Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

SQ

I like Square as a company and see a lot of people are bullish about it. However, a few things stop me from investing. Be interested to hear thoughts but at the moment I am a Square bear.
Management
Jack Dorsey is a visionary. I don’t think this is controversial. However, his track record at Twitter is worrying for shareholders. Be it daily active user growth, ambition with acquisitions but ultimately failure to monetise a fantastic platform where you have big corporations, celebrities and even the President reaching out to 200m daily active users for free. With Square, the closed loop business model of businesses and consumers is again a fantastic concept that could break the power of Visa/Mastercard. Execution remains to be seen, of course.
Competition
Square operate in a highly competitive field for consumers and businesses. Let’s take consumers based on Square’s fast-growing Cash App. It offers things a normal bank does like deposits, ATM access, money transfer. If it becomes a fully-fledged bank offering loans, credit; it is competing against the likes of big incumbents (e.g. JP Morgan, Bank of America). Granted they’re dinosaur firms but they already have a huge customer base that are older and, therefore, have more money and deposits. This means it is much easier for them to monetise their customers resulting in high ARPU. Why would these lucrative customers, en-masse, want to uproot their finances to Square when their existing providers will be providing the same service by copying Square, as JP Morgan have done this week? Link
For businesses, Square’s provides software offering (invoicing, PoS, online store) but face strong competition from the likes of Shopify who are taking a fully integrated service approach to SMEs which allows them to take their business online but also manage all their backend processes, including payments. This is a highly convenient service for entrepreneurs. Shopify already has 6% share of the online retail market. Square also provides hardware products which make it easy for SMEs, in particular, to take payments. However, there is evidence that retail is facing a more permanent shift in the US vs. the rest of the world with 60% less footfall today than a year ago Link. 58% of Square’s GPV is from food/drink, retail and professional services. Square may have good market share but it is a shrinking industry.
And as a final piece, competitors in both spaces are generally in very healthy financial shape: Paypal, Shopify, Global Payments, Western Union and big banks are well-capitalised.
Valuation
Perhaps you can get over the above with the fact that Square has strong network effects and are able to win customers cheaply. However, in my opinion, Square is priced for perfection. Simply looking at a price/sales metric, it is trading 13x LTM. This is high but maybe relatively reasonable for a fast-growing business. However, 25% of Square’s revenue is accounted by Bitcoin “revenue”. This brings little value to Square (2% gross profit) and even Square themselves discount this revenue in their KPIs because it is “out of their control and not reflective of Square’s performance”.
Now onto profits. It is not fair to be too hard on Square’s profitability. After all, it is in high growth phase and its marketing costs were its highest opex line item at roughly 35% for YTD. However, a cursory look at it is Enterprise Value / EBITDA (forward look to Dec2020), it is 242x. If we give credit for Square’s business plan for a further two years, today’s Enterprise Value over broker consensus forecast EBITDA for 2022, it is still a heady 77x. This is when Square is supposed to have EBITDA of $1bn which is three times more than it is forecast for Dec 2020. Priced to perfection.
If you compare it to Paypal, it is trading at 39x and 27x EV / EBITDA for Dec 2020 and 2022.
Conclusion
Square has formidable backers like Ark Invest. I am also not a great believer in “dumb retail” overvaluing a stock for a prolonged period of time. But for reasons above, I am cautious with Square and yet it keeps climbing so please tell me what I am missing…

Bitcoin Newcomers FAQ - Please read!

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
It all started with the release of the release of Satoshi Nakamoto's whitepaper however that will probably go over the head of most readers so we recommend the following videos for a good starting point for understanding how bitcoin works and a little about its long term potential:
Some other great resources include Lopp.net, the Princeton crypto series and James D'Angelo's Bitcoin 101 Blackboard series.
Some excellent writing on Bitcoin's value proposition and future can be found at the Satoshi Nakamoto Institute.
Some Bitcoin statistics can be found here and here. Developer resources can be found here. Peer-reviewed research papers can be found here.
Potential upcoming protocol improvements and scaling resources here and here.
The number of times Bitcoin was declared dead by the media can be found here (LOL!)

Key properties of Bitcoin

Where can I buy bitcoins?

Bitcoin.org and BuyBitcoinWorldwide.com are helpful sites for beginners. You can buy or sell any amount of bitcoin (even just a few dollars worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer. Some of the more popular resources are below, also check out the bitcoinity exchange resources for a larger list of options for purchases.
Here is a listing of local ATMs. If you would like your paycheck automatically converted to bitcoin use Bitwage.
Note: Bitcoins are valued at whatever market price people are willing to pay for them in balancing act of supply vs demand. Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.
Note: For increased security, use Two Factor Authentication (2FA) everywhere it is offered, including email!
2FA requires a second confirmation code to access your account making it much harder for thieves to gain access. Google Authenticator and Authy are the two most popular 2FA services, download links are below. Make sure you create backups of your 2FA codes.
Google Auth Authy OTP Auth
Android Android N/A
iOS iOS iOS

Watch out for scams

As mentioned above, Bitcoin is decentralized, which by definition means there is no official website or Twitter handle or spokesperson or CEO. However, all money attracts thieves. This combination unfortunately results in scammers running official sounding names or pretending to be an authority on YouTube or social media. Many scammers throughout the years have claimed to be the inventor of Bitcoin. Websites like bitcoin(dot)com and the btc subreddit are active scams. Almost all altcoins (shitcoins) are marketed heavily with big promises but are really just designed to separate you from your bitcoin. So be careful: any resource, including all linked in this document, may in the future turn evil. Don't trust, verify. Also as they say in our community "Not your keys, not your coins".

Where can I spend bitcoins?

Check out spendabit or bitcoin directory for millions of merchant options. Also you can spend bitcoin anywhere visa is accepted with bitcoin debit cards such as the CashApp card. Some other useful site are listed below.
Store Product
Gyft Gift cards for hundreds of retailers including Amazon, Target, Walmart, Starbucks, Whole Foods, CVS, Lowes, Home Depot, iTunes, Best Buy, Sears, Kohls, eBay, GameStop, etc.

Coinmap and AirBitz are helpful to find local businesses accepting bitcoins. A good resource for UK residents is at wheretospendbitcoins.co.uk.
There are also lots of charities which accept bitcoin donations.

Merchant Resources

There are several benefits to accepting bitcoin as a payment option if you are a merchant;
If you are interested in accepting bitcoin as a payment method, there are several options available;

Can I mine bitcoin?

Mining bitcoins can be a fun learning experience, but be aware that you will most likely operate at a loss. Newcomers are often advised to stay away from mining unless they are only interested in it as a hobby similar to folding at home. If you want to learn more about mining you can read more here. Still have mining questions? The crew at /BitcoinMining would be happy to help you out.
If you want to contribute to the bitcoin network by hosting the blockchain and propagating transactions you can run a full node using this setup guide. If you would prefer to keep it simple there are several good options. You can view the global node distribution here.

Why Bitcoin is Superior to Gold

There is a constant war being fought between goldbugs, like Peter Schiff, and Bitcoin enthusiasts so I decided to make an outline, with links, comparing and contrasting gold and Bitcoin. I made this in November of 2019 (thus the information therein is based on figures from that time) but, being scatter brained, neglected to post this for the Bitcoin community to see. The yardsticks I used to compare the two assets included the following: shipping/transactions costs, storage costs, censorship factor, settlement time, stock to flow, blockchain vs clearing house, validation, etc. I will also touch on Roosevelt's gold confiscation executive order in 1933, transporting gold during the Spanish Civil War in 1936, and the hypothetical cost for Venezuela to repatriate its gold more recently.
I will provide a brief summary first then follow that with the outline I made. This information can be used as a tool for the Bitcoin community to combat some of the silly rhetoric coming from goldbugs such as Peter Schiff and James Rickards. I would like to make it clear, however, that I am not against gold and think that it performed its role as money very well in a technologically inferior era, namely Victorian times but I think Bitcoin performs the functions of money better than gold does in the current environment.
I have been looking to make a contribution to the Bitcoin community and I hope this is a useful and educational tool for everyone who reads this.
Summary:
Shipping/transaction costs: 100 ounces of gold could be shipped for 315 dollars; the comparable dollar value in Bitcoin could be sent for 35 dollars using a non-segwit address. Using historical precendent, it would cost an estimated $32,997,989 to transport $1 billion in gold using the 3.3% fee that the Soviets charged the Spaniards in 1936; a $1 billion Bitcoin transaction moved for $690 last year by comparison. Please note that the only historic example we can provide for moving enormous sums of gold was when the government of Spain transported gold to Moscow during the Spanish Civil War in 1936. More information on this topic will be found in the notes section.
Storage costs: 100 ounces of gold would require $451 per year to custody while the equivalent value of Bitcoin in dollar terms could be stored for the cost of a Ledger Nano S, $59.99. $1 billion USD value of gold would cost $2,900,000 per year while an Armory set up that is more secure would run you the cost of a laptop, $200-300.
Censorship factor: Gold must pass through a 3rd party whenever it is shipped, whether for a transaction or for personal transportation. Gold will typically have to be declared and a customs duty may be imposed when crossing international borders. The key take-away is gatekeepers (customs) can halt movement of gold thus making transactions difficult. $46,000 of gold was seized in India despite the smugglers hiding it in their rectums.
Settlement time: Shipping gold based on 100 ounces takes anywhere from 3-10 days while Bitcoin transactions clear in roughly 10 minutes depending on network congestion and fee size.
Historic confiscation: Franklin Roosevelt confiscated and debased the paper value of gold in 1933 with Executive Order 6102. Since gold is physical in nature and value dense, it is often stored in custodial vaults like banks and so forth which act as a honeypot for rapacious governments.
Stock to flow: Plan B's stock to flow model has become a favorite on twitter. Stock to flow measures the relationship between the total stock of an asset against the amount that is produced in a given year. Currently gold still has the highest value at 62 while Bitcoin sits at 50 in 2nd place. Bitcoin will overtake gold in 2024 after the next halving.
Blockchain vs clearing house: gold payments historically passed through a 3rd party (clearinghouse) in order to be validated while Bitcoin transactions can be self validated through the use of a node.
Key Takeaway from above- Bitcoin is vastly superior to gold in terms of cost, speed, and censorship resistance. One could theoretically carry around an enormous sum of Bitcoin on a cold card while the equivalent dollar value of gold would require a wheelbarrow...and create an enormous target on the back of the transporter. With the exception of the stock to flow ratio (which will flip in Bitcoin's favor soon), Bitcoin is superior to gold by all metrics covered.

Breaking down Venezuela conundrum; http://blogs.reuters.com/felix-salmon/2011/08/23/how-to-get-12-billion-of-gold-to-venezuela/
“The last (and only) known case of this kind of quantity of gold being transported across state lines took place almost exactly 75 years ago, in 1936, when the government of Spain removed 560 tons of gold from Madrid to Moscow as the armies of Francisco Franco approached. Most of the gold was exchanged for Russian weaponry, with the Soviet Union keeping 2.1% of the funds in the form of commissions and brokerage, and an additional 1.2% in the form of transport, deposit, melting, and refining expenses.”
“Venezuela would need to transport the gold in several trips, traders said, since the high value of gold means it would be impossible to insure a single aircraft carrying 211 tonnes. It could take about 40 shipments to move the gold back to Caracas, traders estimated. “It’s going to be quite a task. Logistically, I’m not sure if the central bank realises the magnitude of the task ahead of them,” said one senior gold banker.”
“So maybe Chávez intends to take matters into his own hands, and just sail the booty back to Venezuela on one of his own naval ships. Again, the theft risk is obvious — seamen can be greedy too — and this time there would be no insurance. Chávez is pretty crazy, but I don’t think he’d risk $12 billion that way.”
“Which leaves one final alternative. Gold is fungible, and people are actually willing to pay a premium to buy gold which is sitting in the Bank of England’s ultra-secure vaults. So why bother transporting that gold at all? Venezuela could enter into an intercontinental repo transaction, where it sells its gold in the Bank of England to some counterparty, and then promises to buy it all back at a modest discount, on condition that it’s physically delivered to the Venezuelan central bank in Caracas. It would then be up to the counterparty to work out how to get 211 tons of gold to Caracas by a certain date. That gold could be sourced anywhere in the world, and transported in any conceivable manner — being much less predictable and transparent, those shipments would also be much harder to hijack. How much of a discount would a counterparty require to enter into this kind of transaction? Much more than 3.3%, is my guess. And again, it’s not entirely clear who would even be willing to entertain the idea. Glencore, perhaps?”
“But here’s one last idea: why doesn’t Chávez crowdsource the problem? He could simply open a gold window at the Banco Central de Venezuela, where anybody at all could deliver standard gold bars. In return, the central bank would transfer to that person an equal number of gold bars in the custody of the Bank of England, plus a modest bounty of say 2% — that’s over $15,000 per 400-ounce bar, at current rates. It would take a little while, but eventually the gold would start trickling in: if you’re willing to pay a constant premium of 2% over the market price for a good, you can be sure that the good in question will ultimately find its way to your door. And the 2% cost of acquiring all that gold would surely be much lower than the cost of insuring and shipping it from England. It would be an elegant market-based solution to an artificial and ideologically-driven problem; I daresay Chávez might even chuckle at the irony of it. He’d just need to watch out for a rise in Andean banditry, as thieves tried to steal the bars on their disparate journeys into Venezuela.”

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Eth 2.0 vs Polkadot and other musings by a fundamental investor

Spent about two hours on this post and I decided it would help the community if I made it more visible. Comment was made as a response to this
I’m trying to avoid falling into a maximalist mindset over time. This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
Can someone help me see the downsides of diversifying into DOTs?
I know Polkadot is more centralized, VC backed, and generally against our ethos here. On chain governance might introduce some unknown risks. What else am I missing?
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
Response:
What else am I missing?
The upsides.
Most of the guys responding to you here are full Eth maxis who drank the Parity is bad koolaid. They are married to their investment and basically emotional / tribal in an area where you should have a cool head. Sure, you might get more upvotes on Reddit if you do and say what the crowd wants, but do you want upvotes and fleeting validation or do you want returns on your investment? Do you want to be these guys or do you want to be the shareholder making bank off of those guys?
Disclaimer: I'm both an Eth whale and a Dot whale, and have been in crypto for close to a decade now. I originally bought ether sub $10 after researching it for at least a thousand hours. Rode to $1500 and down to $60. Iron hands - my intent has always been to reconsider my Eth position after proof of stake is out. I invested in the 2017 Dot public sale with the plan of flipping profits back to Eth but keeping Dots looks like the right short and long term play now. I am not a trader, I just take a deep tech dive every couple of years and invest in fundamentals.
Now as for your concerns:
I know Polkadot is more centralized
The sad truth is that the market doesn't really care about this. At all. There is no real statistic to show at what point a coin is "decentralized" or "too centralized". For example, bitcoin has been completely taken over by Chinese mining farms for about five years now. Last I checked, they control above 85% of the hashing power, they just spread it among different mining pools to make it look decentralized. They have had the ability to fake or block transactions for all this time but it has never been in their best interest to do so: messing with bitcoin in that way would crash its price, therefore their bitcoin holdings, their mining equipment, and their company stock (some of them worth billions) would evaporate. So they won't do it due to economics, but not because they can't.
That is the major point I want to get across; originally Bitcoin couldn't be messed with because it was decentralized, but now Bitcoin is centralized but it's still not messed with due to economics. It is basically ChinaCoin at this point, but the market doesn't care, and it still enjoys over 50% of the total crypto market cap.
So how does this relate to Polkadot? Well fortunately most chains - Ethereum included - are working towards proof of stake. This is obviously better for the environment, but it also has a massive benefit for token holders. If a hostile party wanted to take over a proof of stake chain they'd have to buy up a massive share of the network. The moment they force through a malicious transaction a proof of stake blockchain has the option to fork them off. It would be messy for a few days, but by the end of the week the hostile party would have a large amount of now worthless tokens, and the proof of stake community would have moved on to a version of the blockchain where the hostile party's tokens have been slashed to zero. So not only does the market not care about centralization (Bitcoin example), but proof of stake makes token holders even safer.
That being said, Polkadot's "centralization" is not that far off to Ethereum. The Web3 foundation kept 30% of the Dots while the Ethereum Foundation kept 17%. There are whales in Polkadot but Ethereum has them too - 40% of all genesis Ether went to 100 wallets, and many suspect that the original Ethereum ICO was sybiled to make it look more popular and decentralized than it really was. But you don't really care about that do you? Neither do I. Whales are a fact of life.
VC backed
VCs are part of the crypto game now. There is no way to get rid of them, and there is no real reason why you should want to get rid of them. They put their capital at risk (same as you and me) and seek returns on their investment (same as you and me). They are both in Polkadot and Ethereum, and have been for years now. I have no issue with them as long as they don't play around with insider information, but that is another topic. To be honest, I would be worried if VCs did not endorse chains I'm researching, but maybe that's because my investing style isn't chasing hype and buying SUSHI style tokens from anonymous (at the time) developers. That's just playing hot potato. But hey, some people are good at that.
As to the amount of wallets that participated in the Polkadot ICO: a little known fact is that more individual wallets participated in Polkadot's ICO than Ethereum's, even though Polkadot never marketed their ICO rounds due to regulatory reasons.
generally against our ethos here
Kool aid.
Some guy that works(ed?) at Parity (who employs what, 200+ people?) correctly said that Ethereum is losing its tech lead and that offended the Ethereum hivemind. Oh no. So controversial. I'm so personally hurt by that.
Some guy that has been working for free on Ethereum basically forever correctly said that Polkadot is taking the blockchain tech crown. Do we A) Reflect on why he said that? or B) Rally the mob to chase him off?
"I did not quit social media, I quit Ethereum. I did not go dark, I just left the community. I am no longer coordinating hard forks, building testnets, or contributing otherwise. I did not work on Polkadot, I never did, I worked on Ethereum. I did not hate Ethereum, I loved it."
Also Parity locked their funds (and about 500+ other wallets not owned by them) and proposed a solution to recover them. When the community voted no they backed off and did not fork the chain, even if they had the influence to do so. For some reason this subreddit hates them for that, even if Parity did the 100% moral thing to do. Remember, 500+ other teams or people had their funds locked, so Parity was morally bound to try its best to recover them.
Its just lame drama to be honest. Nothing to do with ethos, everything to do with emotional tribalism.
Now for the missing upsides (I'll also respond to random fragments scattered in the thread):
This isn’t a 100% ETH question, but I’m trying to stay educated about emerging tech.
A good quick intro to Eth's tech vs Polkadot's tech can be found on this thread, especially this reply. That thread is basically mandatory reading if you care about your investment.
Eth 2.0's features will not really kick in for end users until about 2023. That means every dapp (except DeFI, where the fees make sense due to returns and is leading the fee market) who built on Eth's layer 1 are dead for three years. Remember the trading card games... Gods Unchained? How many players do you think are going to buy and sell cards when the transaction fee is worth more than the cards? All that development is now practically worthless until it can migrate to its own shard. This story repeats for hundreds of other dapp teams who's projects are now priced out for three years. So now they either have to migrate to a one of the many unpopulated L2 options (which have their own list of problems and risks, but that's another topic) or they look for another platform, preferably one interoperable with Ethereum. Hence Polkadot's massive growth in developer activity. If you check out https://polkaproject.com/ you'll see 205 projects listed at the time of this post. About a week ago they had 202 listed. That means about one team migrated from another tech stack to build on Polkadot every two days, and trust me, many more will come in when parachains are finally activated, and it will be a complete no brainer when Polkadot 2.0 is released.
Another huge upside for Polkadot is the Initial Parachain Offerings. Polkadot's version of ICOs. The biggest difference is that you can vote for parachains using your Dots to bind them to the relay chain, and you get some of the parachain's tokens in exchange. After a certain amount of time you get your Dots back. The tokenomics here are impressive: Dots are locked (reduced supply) instead of sold (sell pressure) and you still earn your staking rewards. There's no risk of scammers running away with your Ether and the governance mechanism allows for the community to defund incompetent devs who did not deliver what was promised.
Wouldn’t an ETH shard on Polkadot gain a bunch of scaling benefits that we won’t see natively for a couple years?
Yes. That is correct. Both Edgeware and Moonbeam are EVM compatible. And if the original dapp teams don't migrate their projects someone else will fork them, exactly like SUSHI did to Uniswap, and how Acala is doing to MakerDao.
Although realistically Ethereum has a 5 yr headstart and devs haven't slowed down at all
Ethereum had a five year head start but it turns out that Polkadot has a three year tech lead.
Just because it's "EVM Compatible" doesn't mean you can just plug Ethereum into Polkadot or vica versa, it just means they both understand Ethereum bytecode and you can potentially copy/paste contracts from Ethereum to Polkadot, but you'd still need to add a "bridge" between the 2 chains, so it adds additional complexity and extra steps compared to using any of the existing L2 scaling solutions
That only applies of you are thinking from an Eth maximalist perspective. But if you think from Polkadot's side, why would you need to use the bridge back to Ethereum at all? Everything will be seamless, cheaper, and quicker once the ecosystem starts to flourish.
I see a bunch of posts about how Ethereum and Polkadot can thrive together, but are they not both L1 competitors?
They are competitors. Both have their strategies, and both have their strengths (tech vs time on the market) but they are clearly competing in my eyes. Which is a good thing, Apple and Samsung competing in the cell phone market just leads to more innovation for consumers. You can still invest in both if you like.
Edit - link to post and the rest of the conversation: https://www.reddit.com/ethfinance/comments/iooew6/daily_general_discussion_september_8_2020/g4h5yyq/
Edit 2 - one day later PolkaProject count is 210. Devs are getting the hint :)

Spoofing

Caller ID spoofing
It is very easy for anyone to make a phone call while having any number show up on the caller ID of the person receiving the phone call. Receiving a phone call from a certain number does not mean that the person/company who owns that number has actually called you.
Email spoofing
The "from" field of an email can be set by the sender, meaning that you can receive scam emails that look like they are from legitimate addresses. It's important to never click links in emails unless absolutely necessary, for example a password reset link you requested or an account activation link for an account you created.
SMS spoofing
SMS messages can be spoofed, so be wary of messages that seem to be from your friends or other trusted people.

The most common scams

The fake check scam (Credit to nimble2 for this part)
The fake check scam arises from many different situations (for instance, you applied for a job, or you are selling something on a place like Craigslist, or someone wants to purchase goods or services from your business, or you were offered a job as a mystery shopper, you were asked to wrap your car with an advertisement, or you received a check in the mail for no reason), but the bottom line is always something like this:
General fraudulent funds scams If somebody is asking you to accept and send out money as a favour or as part of a job, it is a fraudulent funds scam. It does not matter how they pay you, any payment on any service can be fraudulent and will be reversed when it is discovered to be fraudulent.
Phone verification code scams Someone will ask you to receive a verification text and then tell you to give them the code. Usually the code will come from Google Voice, or from Craigslist. In the Google version of the scam, your phone number will be used to verify a Google Voice account that the scammer will use to scam people with. In the Craigslist version of the scam, your phone number will be used to verify a Craigslist posting that the scammer will use to scam people. There is also an account takeover version of this scam that will involve the scammer sending a password reset token to your phone number and asking you for it.
Bitcoin job scams
Bitcoin job scams involve some sort of fraudulent funds transfer, usually a fake check although a fraudulent bank transfer can be used as well. The scammer will send you the fraudulent money and ask you to purchase bitcoins. This is a scam, and you will have zero recourse after you send the scammer bitcoins.
Email flooding
If you suddenly receive hundreds or thousands of spam emails, usually subscription confirmations, it's very likely that one of your online accounts has been taken over and is being used fraudulently. You should check any of your accounts that has a credit card linked to it, preferably from a computer other than the one you normally use. You should change all of your passwords to unique passwords and you should start using two factor authentication everywhere.
Cartel scam
You will be threatened by scammers who claim to be affiliated with a cartel. They may send you gory pictures and threaten your life and the lives of your family. Usually the victim will have attempted to contact an escort prior to the scam, but sometimes the scammers target people randomly. If you are targeted by a cartel scam all you need to do is ignore the scammers as their threats are clearly empty.
Boss/CEO scam A scammer will impersonate your boss or someone who works at your company and will ask you to run an errand for them, which will usually be purchasing gift cards and sending them the code. Once the scammer has the code, you have no recourse.
Employment certification scams
You will receive a job offer that is dependent on you completing a course or receiving a certification from a company the scammer tells you about. The scammer operates both websites and the job does not exist.
Craigslist fake payment scams
Scammers will ask you about your item that you have listed for sale on a site like Craigslist, and will ask to pay you via Paypal. They are scamming you, and the payment in most cases does not actually exist, the email you received was sent by the scammers. In cases where you have received a payment, the scammer can dispute the payment or the payment may be entirely fraudulent. The scammer will then either try to get you to send money to them using the fake funds that they did not send to you, or will ask you to ship the item, usually to a re-shipping facility or a parcel mule.
Craigslist Carfax/vehicle history scam
You'll encounter a scammer on Craigslist who wants to buy the vehicle you have listed, but they will ask for a VIN report from a random site that they have created and they will expect you to pay for it.
Double dip/recovery scammers
This is a scam aimed at people who have already fallen for a scam previously. Scammers will reach out to the victim and claim to be able to help the victim recover funds they lost in the scam.
General fraudulent funds scams The fake check scam is not the only scam that involves accepting fraudulent/fake funds and purchasing items for scammers. If your job or opportunity involves accepting money and then using that money, it is almost certainly a frauduent funds scam. Even if the payment is through a bank transfer, Paypal, Venmo, Zelle, Interac e-Transfer, etc, it does not matter.
Credit card debt scam
Fraudsters will offer to pay off your bills, and will do so with fraudulent funds. Sometimes it will be your credit card bill, but it can be any bill that can be paid online. Once they pay it off, they will ask you to send them money or purchase items for them. The fraudulent transaction will be reversed in the future and you will never be able to keep the money. This scam happens on sites like Craigslist, Twitter, Instagram, and also some dating sites, including SeekingArrangement.
The parcel mule scam
A scammer will contact you with a job opportunity that involves accepting and reshipping packages. The packages are either stolen or fraudulently obtained items, and you will not be paid by the scammer. Here is a news article about a scam victim who fell for this scam and reshipped over 20 packages containing fraudulently acquired goods.
The Skype sex scam
You're on Facebook and you get a friend request from a cute girl you've never met. She wants to start sexting and trading nudes. She'll ask you to send pictures or videos or get on webcam where she can see you naked with your face in the picture. The scam: There's no girl. You've sent nudes to a guy pretending to be a girl. As soon as he has the pictures he'll demand money and threaten to send the pictures to your friends and family. Sometimes the scammer will upload the video to a porn site or Youtube to show that they are serious.
What to do if you are a victim of this scam: You cannot buy silence, you can only rent it. Paying the blackmailer will show them that the information they have is valuable and they will come after you for more money. Let your friends and family know that you were scammed and tell them to ignore friend requests or messages from people they don't know. Also, make sure your privacy settings are locked down and consider deactivating your account.
The underage girl scam
You're on a dating site or app and you get contacted by a cute girl. She wants to start sexting and trading nudes. Eventually she stops communicating and you get a call from a pissed off guy claiming to be the girl's father, or a police officer, or a private investigator, or something else along those lines. Turns out the girl you were sexting is underage, and her parents want some money for various reasons, such as to pay for a new phone, to pay for therapy, etc. There is, of course, no girl. You were communicating with a scammer.
What to do if you are a victim of this scam: Stop picking up the phone when the scammers call. Do not pay them, or they will be after you for more money.
Phishing
Phishing is when a scammer tries to trick you into giving information to them, such as your password or private financial information. Phishing messages will usually look very similar to official messages, and sometimes they are identical. If you are ever required to login to a different account in order to use a service, you should be incredibly cautious.

PSA: you did not win a giftcard: https://old.reddit.com/Scams/comments/fffmle/psa_you_did_not_win_a_gift_card/
Sugar scams
Sugar scammers operate all over the internet and usually come in two varieties: advance-fee scams where the scammer will ask for a payment from you before sending you lots of money, and fake check style scams where the scammer will either pull a classic fake check scam, or will do a "bill pay" style scam that involves them paying your bills, or them giving you banking information to pay your bills. If you encounter these scammers, report their accounts and move on.
Google Hangouts
Google Hangouts is a messaging platform used extensively by all kinds of scammers. If you are talking with someone online and they want you to switch to Hangouts, they are likely a scammer and you should proceed with caution.
Publishers Clearing House scams
PCH scams are often advance-fee scams, where you will be promised lots of money after you make an initial payment. You will never need to pay if you win money from the real PCH.
Pet scams
You are looking for a specific breed of puppy, bird, or other pet. You come across a nice-looking website that claims to be breeding them and has some available right now - they may even be on sale! The breeders are not local to your area (and may not even list a physical location) but they assure you they can safely ship the pet to you after a deposit or full payment. If you go through with the payment, you will likely be contacted by the "shipper" who will inform you about an unexpected shipping/customs/processing fee required to deliver your new pet. But there was never any pet, both the "breeder" and the "shipper" are scammers, typically operating out of Africa. These sites are rampant and account for a large percentage of online pet seller websites - they typically have a similar layout/template (screenshot - example)
If you are considering buying a pet online, some easy things to check are: (1) The registration date of the domain (if it was created recently it is likely a scam website) (2) Reverse image search the pictures of available pets - you will usually find other scam websites using the same photos. (3) Copy a sentence/section of the text from the "about us" page and put it into google (in quotes) - these scammers often copy large parts of their website's text from other places. (4) Search for the domain name and look for entries on petscams.com or other scam-tracking sites. (5) Strongly consider buying/adopting your pet from a local shelter or breeder where you can see the animal in person before putting any money down.
Thanks to djscsi for this entry.
Fake shipping company scams
These scams usually start when you try to buy something illegal online. You will be scammed for the initial payment, and then you will receive an email from the fake shipping company telling you that you need to pay them some sort of fee or bribe. If you pay this, they will keep trying to scam you with increasingly absurd stories until you stop paying, at which point they will blackmail you. If you are involved in this scam, all you can do is ignore the scammers and move on, and try to dispute your payments if possible.
Chinese Upwork scam
Someone will ask you to create an Upwork or other freelancer site account for them and will offer money in return. You will not be paid, and they want to use the accounts to scam people.
Quickbooks invoice scam
This is a fake check style scam that takes advantage of Quickbooks.
The blackmail email scam The exact wording of the emails varies, but there are generally four main parts. They claim to have placed software/malware on a porn/adult video site, they claim to have a video of you masturbating or watching porn, they threaten to release the video to your friends/family/loved ones/boss/dog, and they demand that you pay them in order for them to delete the video. Rest assured that this is a very common spam campaign and there is no truth behind the email or the threats. Here are some news articles about this scam.
The blackmail mail scam
This is very similar to the blackmail email scam, but you will receive a letter in the mail.
Rental scams Usually on local sites like Craigslist, scammers will steal photos from legitimate real estate listings and will list them for rent at or below market rate. They will generally be hesitant to tell you the address of the property for "safety reasons" and you will not be able to see the unit. They will then ask you to pay them a deposit and they claim they will ship you the keys. In reality, your money is gone and you will have no recourse.
Craigslist vehicle scams A scammer will list a vehicle on Craigslist and will offer to ship you the car. In many cases they will also falsely claim to sell you the car through eBay or Amazon. If you are looking for a car on Craigslist and the seller says anything about shipping the car, having an agent, gives you a long story about why they are selling the car, or the listing price is far too low, you are talking to a scammer and you should ignore and move on.
Advance-fee scam, also known as the 419 scam, or the Nigerian prince scam. You will receive a communication from someone who claims that you are entitled to a large sum of money, or you can help them obtain a large sum of money. However, they will need money from you before you receive the large sum.
Man in the middle scams
Man in the middle scams are very common and very hard to detect. The scammer will impersonate a company or person you are legitimately doing business with, and they will ask you to send the money to one of their own bank accounts or one controlled by a money mule. They have gained access to the legitimate persons email address, so there will be nothing suspicious about the email. To prevent this, make contact in a different way that lets you verify that the person you are talking to is the person you think you are talking to.
Digit wallet scam
A variation of the fake check scam, the scammer sends you money through a digital wallet (i.e. Venmo, Apple Pay, Zelle, Cash App) along with a message claiming they've sent the money to the wrong person and a request to send the money back. Customer service for these digital wallets may even suggest that you send the money back. However, the money sent is from a stolen credit card and will be removed from your account after a few days. Your transfer is not reversed since it came from your own funds.
Cam girl voting/viewer scam
You will encounter a "cam girl" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to go to their site and sign up with your credit card. They may offer a free show, or ask you to vote for them, or any number of other fake stories.
Amateur porn recruitment scam
You will encounter a "pornstar" on a dating/messaging/social media/whatever site/app, and the scammer will ask you to create an adult film with hehim, but first you need to do something. The story here is usually something to do with verifying your age, or you needing to take an STD test that involves sending money to a site operated by the scammer.
Hot girl SMS spam
You receive a text from a random number with a message along the lines of "Hey babe I'm here in town again if you wanted to meet up this time, are you around?" accompanied by a NSFW picture of a hot girl. It's spam, and they'll direct you to their scam website that requires a credit card.
Identity verification scam
You will encounter someone on a dating/messaging/social media/whatever site/app, and the scammer will ask that you verify your identity as they are worried about catfishing. The scammer operates the site, and you are not talking to whoever you think you are talking to.
This type of scam teases you with something, then tries to make you sign up for something else that costs money. The company involved is often innocent, but they turn a blind eye to the practice as it helps their bottom line, even if they have to occasionally issue refunds. A common variation takes place on dating sites/dating apps, where you will match with someone who claims to be a camgirl who wants you to sign up for a site and vote for her. Another variation takes place on local sites like Craigslist, where the scammers setup fake rental scams and demand that you go through a specific service for a credit check. Once you go through with it, the scammer will stop talking to you. Another variation also takes place on local sites like Craigslist, where scammers will contact you while you are selling a car and will ask you to purchase a Carfax-like report from a specific website.
Multi Level Marketing or Affiliate Marketing
You apply for a vague job listing for 'sales' on craigslist. Or maybe an old friend from high school adds you on Facebook and says they have an amazing business opportunity for you. Or maybe the well dressed guy who's always interviewing people in the Starbucks that you work at asks if you really want to be slinging coffee the rest of your life. The scam: MLMs are little more than pyramid schemes. They involve buying some sort of product (usually snake oil health products like body wraps or supplements) and shilling them to your friends and family. They claim that the really money is recruiting people underneath you who give you a slice of whatever they sell. And if those people underneath you recruit more people, you get a piece of their sales. Ideally if you big enough pyramid underneath you the money will roll in without any work on your part. Failure to see any profit will be your fault for not "wanting it enough." The companies will claim that you need to buy their extra training modules or webinars to really start selling. But in reality, the vast majority of people who buy into a MLM won't see a cent. At the end of the day all you'll be doing is annoying your friends and family with your constant recruitment efforts. What to look out for: Recruiters love to be vague. They won't tell you the name of the company or what exactly the job will entail. They'll pump you up with promises of "self-generating income", "being your own boss", and "owning your own company." They might ask you to read books about success and entrepreneurs. They're hoping you buy into the dream first. If you get approached via social media, check their timelines. MLMs will often instruct their victims to pretend that they've already made it. They'll constantly post about how they're hustling and making the big bucks and linking to youtube videos about success. Again, all very vague about what their job actually entails. If you think you're being recruited: Ask them what exactly the job is. If they can't answer its probably a MLM. Just walk away.

Phone scams

You should generally avoid answering or engaging with random phone calls. Picking up and engaging with a scam call tells the scammers that your phone number is active, and will usually lead to more calls.
Tax Call
You get a call from somebody claiming to be from your countries tax agency. They say you have unpaid taxes that need to be paid immediately, and you may be arrested or have other legal action taken against you if it is not paid. This scam has caused the American IRS, Canadian CRA, British HMRC, and Australian Tax Office to issue warnings. This scam happens in a wide variety of countries all over the world.
Warrant Call
Very similar to the tax call. You'll get a phone call from an "agent", "officer", "sheriff", or other law enforcement officer claiming that there is a warrant out for your arrest and you will be arrested very soon. They will then offer to settle everything for a fee, usually paid in giftcards.
[Legal Documents/Process Server Calls]
Very similar to the warrant call. You'll get a phone call from a scammer claiming that they are going to serve you legal documents, and they will threaten you with legal consequences if you refuse to comply. They may call themselves "investigators", and will sometimes give you a fake case number.
Student Loan Forgiveness Scam
Scammers will call you and tell you about a student loan forgiveness program, but they are interested in obtaining private information about you or demanding money in order to join the fake program.
Tech Support Call You receive a call from someone with a heavy accent claiming to be a technician Microsoft or your ISP. They inform you that your PC has a virus and your online banking and other accounts may be compromised if the virus is not removed. They'll have you type in commands and view diagnostics on your PC which shows proof of the virus. Then they'll have you install remote support software so the technician can work on your PC, remove the virus, and install security software. The cost of the labor and software can be hundreds of dollars. The scam: There's no virus. The technician isn't a technician and does not work for Microsoft or your ISP. Scammers (primarily out of India) use autodialers to cold-call everyone in the US. Any file they point out to you or command they have you run is completely benign. The software they sell you is either freeware or ineffective. What to do you if you're involved with this scam: If the scammers are remotely on your computer as you read this, turn off your PC or laptop via the power button immediately, and then if possible unplug your internet connection. Some of the more vindictive tech scammers have been known to create boot passwords on your computer if they think you've become wise to them and aren't going to pay up. Hang up on the scammers, block the number, and ignore any threats about payment. Performing a system restore on your PC is usually all that is required to remove the scammer's common remote access software. Reports of identity theft from fake tech calls are uncommon, but it would still be a good idea to change your passwords for online banking and monitor your accounts for any possible fraud. How to avoid: Ignore any calls claiming that your PC has a virus. Microsoft will never contact you. If you're unsure if a call claiming to be from your ISP is legit, hang up, and then dial the customer support number listed on a recent bill. If you have elderly relatives or family that isn't tech savvy, take the time to fill them in on this scam.
Chinese government scam
This scam is aimed at Chinese people living in Europe and North America, and involves a voicemail from someone claiming to be associated with the Chinese government, usually through the Chinese consulate/embassy, who is threatening legal action or making general threats.
Chinese shipping scam
This scam is similar to the Chinese government scam, but involves a seized/suspicious package, and the scammers will connect the victim to other scammers posing as Chinese government investigators.
Social security suspension scam
You will receive a call from someone claiming to work for the government regarding suspicious activity, fraud, or serious crimes connected to your social security number. You'll be asked to speak to an operator and the operator will explain the steps you need to follow in order to fix the problems. It's all a scam, and will lead to you losing money and could lead to identity theft if you give them private financial information.
Utilities cutoff
You get a call from someone who claims that they are from your utility company, and they claim that your utilities will be shut off unless you immediately pay. The scammer will usually ask for payment via gift cards, although they may ask for payment in other ways, such as Western Union or bitcoin.
Relative in custody Scammer claims to be the police, and they have your son/daughtenephew/estranged twin in custody. You need to post bail (for some reason in iTunes gift cards or MoneyGram) immediately or the consequences will never be the same.
Mexican family scam
This scam comes in many different flavours, but always involves someone in your family and Mexico. Sometimes the scammer will claim that your family member has been detained, sometimes the scammer will claim that your family member has been kidnapped, and sometimes the scammer will claim that your family member is injured and needs help.
General family scams
Scammers will gather a large amount of information about you and target your family members using different stories with the goal of gettimg them to send money.
One ring scam
Scammers will call you from an international number with the goal of getting you to return their call, causing you to incur expensive calling fees.

Online shopping scams

THE GOLDEN RULE OF ONLINE SHOPPING: If it sounds too good to be true, it probably is.
Dropshipping
An ad on reddit or social media sites like Facebook and Instagram offers items at huge discounts or even free (sometimes requiring you to reblog or like their page). They just ask you to pay shipping. The scam: The item will turn out to be very low quality and will take weeks or even months to arrive. Sometimes the item never arrives, and the store disappears or stops responding. The seller drop-ships the item from China. The item may only cost a few dollars, and the Chinese government actually pays for the shipping. You end up paying $10-$15 dollars for a $4 item, with the scammer keeping the profit. If you find one of these scams but really have your heart set on the item, you can find it on AliExpress or another Chinese retailer.
Influencer scams
A user will reach out to you on a social media platform, usually Instagram, and offer you the chance to partner with them and receive a free/discounted product, as long as you pay shipping. This is a different version of the dropshipping scam, and is just a marketing technique to get you to buy their products.
Triangulation fraud
Triangulation fraud occurs when you make a purchase on a site like Amazon or eBay for an item at a lower than market price, and receive an item that was clearly purchased new at full price. The scammer uses a stolen credit card to order your item, while the money from the listing is almost all profit for the scammer.
Instagram influencer scams
Someone will message you on Instagram asking you to promote their products, and offering you a discount code. The items are Chinese junk, and the offer is made to many people at a time.
Cheap Items
Many websites pop up and offer expensive products, including electronics, clothes, watches, sunglasses, and shoes at very low prices. The scam: Some sites are selling cheap knock-offs. Some will just take your money and run. What to do if you think you're involved with this scam: Contact your bank or credit card and dispute the charge. How to avoid: The sites often have every brand-name shoe or fashion item (Air Jordan, Yeezy, Gucci, etc) in stock and often at a discounted price. The site will claim to be an outlet for a major brand or even a specific line or item. The site will have images at the bottom claiming to be Secured by Norton or various official payment processors but not actual links. The site will have poor grammar and a mish-mash of categories. Recently, established websites will get hacked or their domain name jacked and turned into scam stores, meaning the domain name of the store will be completely unrelated to the items they're selling. If the deal sounds too good to be true it probably is. Nobody is offering brand new iPhones or Beats or Nintendo Switches for 75% off.
Cheap Amazon 3rd Party Items
You're on Amazon or maybe just Googling for an item and you see it for an unbelievable price from a third-party seller. You know Amazon has your back so you order it. The scam: One of three things usually happen: 1) The seller marks the items as shipped and sends a fake tracking number. Amazon releases the funds to the seller, and the seller disappears. Amazon ultimately refunds your money. 2) The seller immediately cancels the order and instructs you to re-order the item directly from their website, usually with the guarantee that the order is still protected by Amazon. The seller takes your money and runs. Amazon informs you that they do not offer protection on items sold outside of Amazon and cannot help you. 2) The seller immediately cancels the order and instructs you to instead send payment via an unused Amazon gift card by sending the code on the back via email. Once the seller uses the code, the money on the card is gone and cannot be refunded. How to avoid: These scammers can be identified by looking at their Amazon storefronts. They'll be brand new sellers offering a wide range of items at unbelievable prices. Usually their Amazon names will be gibberish, or a variation on FIRSTNAME.LASTNAME. Occasionally however, established storefronts will be hacked. If the deal is too good to be true its most likely a scam.
Scams on eBay
There are scams on eBay targeting both buyers and sellers. As a seller, you should look out for people who privately message you regarding the order, especially if they ask you to ship to a different address or ask to negotiate via text/email/a messaging service. As a buyer you should look out for new accounts selling in-demand items, established accounts selling in-demand items that they have no previous connection to (you can check their feedback history for a general idea of what they bought/sold in the past), and lookout for people who ask you to go off eBay and use another service to complete the transaction. In many cases you will receive a fake tracking number and your money will be help up for up to a month.
Scams on Amazon
There are scams on Amazon targeting both buyers and sellers. As a seller, you should look out for people who message you about a listing. As a buyer you should look out for listings that have an email address for you to contact the person to complete the transaction, and you should look out for cheap listings of in-demand items.
Scams on Reddit
Reddit accounts are frequently purchased and sold by fraudsters who wish to use the high karma count + the age of the account to scam people on buy/sell subreddits. You need to take precautions and be safe whenever you are making a transaction online.
Computer scams
Virus scam
A popup or other ad will say that you have a virus and you need to follow their advice in order to remove it. They are lying, and either want you to install malware or pay for their software.

Assorted scams

Chinese Brushing / direct shipping
If you have ever received an unsolicited small package from China, your address was used to brush. Vendors place fake orders for their own products and send out the orders so that they can increase their ratings.
Money flipping
Scammer claims to be a banking insider who can double/triple/bazoople any amount of money you send them, with no consequences of any kind. Obviously, the money disappears into their wallet the moment you send it.

Zano Newcomers Introduction/FAQ - please read!

Welcome to the Zano Sticky Introduction/FAQ!

https://preview.redd.it/al1gy9t9v9q51.png?width=424&format=png&auto=webp&s=b29a60402d30576a4fd95f592b392fae202026ca
Hopefully any questions you have will be answered by the resources below, but if you have additional questions feel free to ask them in the comments. If you're quite technically-minded, the Zano whitepaper gives a thorough overview of Zano's design and its main features.
So, what is Zano? In brief, Zano is a project started by the original developers of CryptoNote. Coins with market caps totalling well over a billion dollars (Monero, Haven, Loki and countless others) run upon the codebase they created. Zano is a continuation of their efforts to create the "perfect money", and brings a wealth of enhancements to their original CryptoNote code.
Development happens at a lightning pace, as the Github activity shows, but Zano is still very much a work-in-progress. Let's cut right to it:
Here's why you should pay attention to Zano over the next 12-18 months. Quoting from a recent update:
Anton Sokolov has recently joined the Zano team. ... For the last months Anton has been working on theoretical work dedicated to log-size ring signatures. These signatures theoretically allows for a logarithmic relationship between the number of decoys and the size/performance of transactions. This means that we can set mixins at a level from up to 1000, keeping the reasonable size and processing speed of transactions. This will take Zano’s privacy to a whole new level, and we believe this technology will turn out to be groundbreaking!
If successful, this scheme will make Zano the most private, powerful and performant CryptoNote implementation on the planet. Bar none. A quantum leap in privacy with a minimal increase in resource usage. And if there's one team capable of pulling it off, it's this one.

What else makes Zano special?

You mean aside from having "the Godfather of CryptoNote" as the project lead? ;) Actually, the calibre of the developers/researchers at Zano probably is the project's single greatest strength. Drawing on years of experience, they've made careful design choices, optimizing performance with an asynchronous core architecture, and flexibility and extensibility with a modular code structure. This means that the developers are able to build and iterate fast, refining features and adding new ones at a rate that makes bigger and better-funded teams look sluggish at best.
Zano also has some unique features that set it apart from similar projects:
Privacy Firstly, if you're familiar with CryptoNote you won't be surprised that Zano transactions are private. The perfect money is fungible, and therefore must be untraceable. Bitcoin, for the most part, does little to hide your transaction data from unscrupulous observers. With Zano, privacy is the default.
The untraceability and unlinkability of Zano transactions come from its use of ring signatures and stealth addresses. What this means is that no outside observer is able to tell if two transactions were sent to the same address, and for each transaction there is a set of possible senders that make it impossible to determine who the real sender is.
Hybrid PoW-PoS consensus mechanism Zano achieves an optimal level of security by utilizing both Proof of Work and Proof of Stake for consensus. By combining the two systems, it mitigates their individual vulnerabilities (see 51% attack and "nothing at stake" problem). For an attack on Zano to have even a remote chance of success the attacker would have to obtain not only a majority of hashing power, but also a majority of the coins involved in staking. The system and its design considerations are discussed at length in the whitepaper.
Aliases Here's a stealth address: ZxDdULdxC7NRFYhCGdxkcTZoEGQoqvbZqcDHj5a7Gad8Y8wZKAGZZmVCUf9AvSPNMK68L8r8JfAfxP4z1GcFQVCS2Jb9wVzoe. I have a hard enough time remembering my phone number. Fortunately, Zano has an alias system that lets you register an address to a human-readable name. (@orsonj if you want to anonymously buy me a coffee)
Multisig
Multisignature (multisig) refers to requiring multiple keys to authorize a Zano transaction. It has a number of applications, such as dividing up responsibility for a single Zano wallet among multiple parties, or creating backups where loss of a single seed doesn't lead to loss of the wallet.
Multisig and escrow are key components of the planned Decentralized Marketplace (see below), so consideration was given to each of them from the design stages. Thus Zano's multisig, rather than being tagged on at the wallet-level as an afterthought, is part of its its core architecture being incorporated at the protocol level. This base-layer integration means months won't be spent in the future on complicated refactoring efforts in order to integrate multisig into a codebase that wasn't designed for it. Plus, it makes it far easier for third-party developers to include multisig (implemented correctly) in any Zano wallets and applications they create in the future.
(Double Deposit MAD) Escrow
With Zano's escrow service you can create fully customizable p2p contracts that are designed to, once signed by participants, enforce adherence to their conditions in such a way that no trusted third-party escrow agent is required.

The Particl project, aside from a couple of minor differences, uses an escrow scheme that works the same way, so I've borrowed the term they coined ("Double Deposit MAD Escrow") as I think it describes the scheme perfectly. The system requires participants to make additional deposits, which they will forfeit if there is any attempt to act in a way that breaches the terms of the contract. Full details can be found in the Escrow section of the whitepaper.
The usefulness of multisig and the escrow system may not seem obvious at first, but as mentioned before they'll form the backbone of Zano's Decentralized Marketplace service (described in the next section).

What does the future hold for Zano?

The planned upgrade to Zano's privacy, mentioned at the start, is obviously one of the most exciting things the team is working on, but it's not the only thing.
Zano Roadmap
Decentralized Marketplace
From the beginning, the Zano team's goal has been to create the perfect money. And money can't just be some vehicle for speculative investment, money must be used. To that end, the team have created a set of tools to make it as simple as possible for Zano to be integrated into eCommerce platforms. Zano's API’s and plugins are easy to use, allowing even those with very little coding experience to use them in their E-commerce-related ventures. The culmination of this effort will be a full Decentralized Anonymous Marketplace built on top of the Zano blockchain. Rather than being accessed via the wallet, it will act more as a service - Marketplace as a Service (MAAS) - for anyone who wishes to use it. The inclusion of a simple "snippet" of code into a website is all that's needed to become part a global decentralized, trustless and private E-commerce network.
Atomic Swaps
Just as Zano's marketplace will allow you to transact without needing to trust your counterparty, atomic swaps will let you to easily convert between Zano and other cyryptocurrencies without having to trust a third-party service such as a centralized exchange. On top of that, it will also lead to the way to Zano's inclusion in the many decentralized exchange (DEX) services that have emerged in recent years.

Where can I buy Zano?

Zano's currently listed on the following exchanges:
https://coinmarketcap.com/currencies/zano/markets/
It goes without saying, neither I nor the Zano team work for any of the exchanges or can vouch for their reliability. Use at your own risk and never leave coins on a centralized exchange for longer than necessary. Your keys, your coins!
If you have any old graphics cards lying around(both AMD & NVIDIA), then Zano is also mineable through its unique ProgPowZ algorithm. Here's a guide on how to get started.
Once you have some Zano, you can safely store it in one of the desktop or mobile wallets (available for all major platforms).

How can I support Zano?

Zano has no marketing department, which is why this post has been written by some guy and not the "Chief Growth Engineer @ Zano Enterprises". The hard part is already done: there's a team of world class developers and researchers gathered here. But, at least at the current prices, the team's funds are enough to cover the cost of development and little more. So the job of publicizing the project falls to the community. If you have any experience in community building/growth hacking at another cryptocurrency or open source project, or if you're a Zano holder who would like to ensure the project's long-term success by helping to spread the word, then send me a pm. We need to get organized.
Researchers and developers are also very welcome. Working at the cutting edge of mathematics and cryptography means Zano provides challenging and rewarding work for anyone in those fields. Please contact the project's Community Manager u/Jed_T if you're interested in joining the team.
