Particl Marketplace: Where Sellers Meet Buyers

Particl Marketplace: Where Sellers Meet Buyers
People had been speculating since the dawn of crypto when the world’s largest online marketplaces, the ones of the Amazon caliber like eBay, Etsy or AliExpress, and, well, Amazon itself, would start to accept cryptocurrencies. There were a slew of rumors, opinions, and theories thickly interspersed with false reports popping up here and there of Amazon and its little cousins being on the verge of embracing cryptocurrencies. On top of that, someone has actually posted a petition on change.org to add Ether to Amazon as a payment method.

Long story short, that was a waste of time. High hopes fell flat, and people lost religion. But not all. As the common wisdom goes, when hope dies, action begins. This exposition describes one such effort which tries to bring to fruition the idea of a decentralized marketplace for trading goods and services. And as you might have already figured it out, with a cryptocurrency as a means of payment. So let’s welcome Particl Marketplace and see what it has to offer – and what Amazon has missed.

What is it, in simple words?

Particl Marketplace is an online marketplace where you can trade goods and services. Not a big deal, you may think. However, what distinguishes it from places like Amazon as well as cryptocurrency-enabled marketplaces is the decentralized nature of purchases on Particl. You can think of it as a variety of a decentralized cryptocurrency exchange (aka DEX) where trades are being conducted on-chain. But in case of Particl, it is goods and services that are being traded, not fiat or crypto, with deals on-chain as well, fully encrypted and decentralized.
Particl is a global peer-to-peer privacy-centered marketplace that uses an automated two-party escrow system. It is crypto-agnostic and designed to work with any cryptocurrency, creating a secure, highly-scalable environment supported by a privacy-focused blockchain-based platform. The team behind the project sees its mission in developing “a new decentralized, private and democratic economy” that is governed by the network of its users, with no central authority or middleman getting in the way.
In the project developers’ own words, Particl enables everyone to participate in a free, anonymous exchange of all kinds of goods, without paying any fee and regardless of geographical location. To be sure, you are already thinking about Silk Road and its dark fate, and that the government is going to crack down monumentally on Particl one day. Well, the outcome may vary as the payments on the platform are made using its own cryptocurrency PART, with its laser focus on privacy and anonymity. But more on this later.

How did it grow up?

The development of the Particl project started in early 2017 with the release of the white paper describing the team’s vision for the marketplace, which was shortly followed by a successful seed funding that brought in enough funds ($750,000) to support the development of the project for a year (it turned out sufficient to last for over two years).
These donations helped to establish the Particl Foundation, a non-profit Swiss organization with the goal of providing legal protection for the project to ensure its sustained development and compliance with government regulations. It receives 10% of all the staking rewards generated on the Particl network, making the project self-sustainable and free for most uses.
Unlike other such projects in the crypto arena, Particl has been using its own blockchain from day one, which happened to be July 17, 2017. It was specifically designed to be crypto agnostic by supporting and working with any cryptocurrency. Additionally, it supported the smart contract tech out of the box, giving users an ability to build all kinds of decentralized applications (dApps) that can be directly integrated into the Particl marketplace.
On May 31, 2018, the Particl Marketplace, the Holy Grail of the entire endeavor, was made available for alpha testing on the testnet of the project, which later split into development and stable branches. It went live with the mainnet release of the Particl Open Marketplace on August 12, 2019, which featured Particl Desktop 2.0.0, a client-side application providing user interface and built-in wallet functions.
On November 25, 2019, the Particl Desktop 2.3.0 client was released that enabled Bitcoin payments and marked the introduction of untraceable transactions. With the help of the new in-wallet exchange module, everyone can easily swap their bitcoins for the native PART coin. Moreover, the module allows seamless integration of third-party accountless exchange services right into the marketplace, with StealthEX being one of them.

How is it different from other marketplaces?

The common solution many P2P marketplaces implement to protect buyers and sellers from the other party failing to honor their end of the bargain is through third-party escrow, where the “third-party” in the majority of places and cases is the platform itself that the market participants must mutually trust. In short, it is a single point of failure. And the selling (pardon the pun) point of the entire Particl’s marketplace is its decentralized escrow, which is a thing entirely between the two parties engaged. No middlemen allowed here!
And these are not empty words. Particl implements the concept best known as Mutually Assured Destruction (aptly shortened as MAD), a military doctrine you are certainly familiar with, and probably even afraid of, that consists in a mutual destruction of two belligerent parties in an all-out nuclear holocaust. If you are curious, the idea stems from the game theory and has a lot to do with the Nash Equilibrium, of John Nash’s fame. In a nutshell, Particl removes the need for a trusted escrow agent by introducing MAD escrow smart contracts.
A MAD escrow contract allows to lock funds in a multi-signature address that can be released only if all the parties sign off on the transaction. So both the seller and the buyer lock in the contract an agreed amount for a specified period of time, with the buyer also depositing the payment for the items purchased. The escrowed funds are released when both parties confirm the fulfillment of the agreement. Should one party break the terms, the funds remain locked for good causing a mutual financial loss until both parties agree to sign off.
Another crucial aspect of Particl Marketplace is its end-to-end privacy. The problem with conventional marketplaces acting as an escrow agent is that the communication between the parties should be open to the agent for it to serve as an arbitrator. With Particl, it is no longer required, and all messages between the buyer and the seller are encrypted. Despite being public, only their recipient can decrypt them, which effectively makes messages untraceable.
This is also where the PART coin turns up quite handy. It enables three different privacy modes, and with the most secure mode, the Anon mode, PART transactions utilize the RingCT privacy protocol, which hides both the amount transferred and the identity of the parties transacting. Accordingly, every part of the entire Particl trading environment is thoroughly decentralized, and the full anonymity of market participants is maintained at all times, making the platform a completely trustless marketplace. Big Brother is no longer watching you.
Aside from that, you can stake PART and generate a source of passive income for yourself. Particl uses a custom Proof-of-Stake consensus protocol, allowing you to get a piece of the pie in the form of new coins created at each block according to the scheduled inflation process. The annual inflation rate is initially set to 5% and goes down 1 percentage point every year until it finally floors at 2% indefinitely. Moreover, these rates are a bare minimum as they assume that all PART coins have been staked. Otherwise, the income will be bigger and better as the same rewards are paid to fewer coins.
Additionally, your passive income through staking PART will be augmented by the fees generated through the everyday marketplace operations. Whether it is network fees collected via PART transactions or marketplace listing fees paid by the sellers, all of them contribute to the stakers’ rewards. At the end of the day, staking PART can turn into a profitable business once the Particl platform starts to attract more traffic. In simple words, the more popular the market gets, the more fees it generates, the more coins the stakers earn.
As PART is a standalone cryptocurrency, it can be used outside Particl Marketplace as well. So if you plan on using it for purposes other than eCommerce, it is traded on several exchanges, for example, HitBTC and Bittrex, with more exchanges to list PART in the future. There are native Particl wallets available for storing PART such as Particl Qt with Ledger support, Particl-cli, and Particl Copay Wallet, with the latter available for both the desktop and the mobile. There is also a third-party multicurrency Flare Wallet, enabling cold staking for Particl.
Running Particl is a collective effort, which means no operational costs and no company bagging profits from it. The marketplace buyers don’t pay any commissions other than tiny network confirmation fees, while the sellers are only charged a small listing fee to keep spam listings to a minimum. This creates a highly competitive environment, with the sellers making more profits and the buyers having access to cheaper goods and services as a result.

What’s in the pipeline?

The next major release of the Particl Marketplace should have been Particl Desktop 2.4.0, but it was later rebranded as Particl Desktop 3.0 to reflect its breakthrough nature. It is set for release in the second half of 2020 and will enable the addition of user-created markets and storefronts, effectively turning the Particl marketplace into a network of specialized markets.
And if you think about it, that makes perfect sense. Say, you have a social network account highly merited and full of karma that you want to sell, whatever your reasons might be. Then creating a dedicated market for trading such accounts privately and securely may look extremely appealing to you. Whether it is the right thing to do is another matter, of course.
Kidding aside, it is obviously not about selling or offering something that the society on the whole doesn’t approve of or frowns upon. If you are a freelancer, for example, a graphics designer or a translator, you would be certainly interested in the future freelancer markets – along with your potential employers. Put simply, birds of a feather should flock together.
To keep things in perspective, popular freelancer markets that exist today charge up to 10-20% of what you would get from your client if you negotiated directly. All in all, establishing communities across the marketplace seems to be the next logical step in the natural evolution and growth of the platform. In fact, it is a little surprising that the Particl team didn’t come up with this idea earlier.
Meanwhile, we wish Particl success and good luck in achieving their goals and aspirations.

How to Store Your Bitcoin

Before holding any bitcoin, you need somewhere to store it. Just like in the physical world, you store your bitcoin in a wallet.
Similar to a bank account number, your wallet comes with a wallet address that shows up in a ledger search and is shared with others so you can make transactions. This address, which is a shorter, more usable version of your public key, consists of between 26 and 35 random alphanumeric characters, something like 1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa. Keep in mind that every letter and number in that address is important. Before sending any bitcoin to your wallet, double-check the entire address, character by character.
Also tied to your wallet address is one or more private keys, which as the name suggests should not be shared with anyone. Keys are used to verify you own the aforementioned public key, and to sign off on transactions. Some wallets create a secure seed phrase, a set of words that will allow you to unlock your wallet if you lose your keys. Print this phrase out and keep it in a safe place.
The unfortunate truth is your bitcoin wallet is akin to your physical wallet. If you lose the private keys to your wallet, you’re most likely going to lose the currency in it forever.
Your wallet generates a master file where your public and private keys are stored. This file should be backed up in case the original file is lost or damaged. Otherwise, you risk losing access to your funds.
You can store your private keys on your computer, mobile device, on a physical storage gadget or even on a piece of paper. It’s crucial that you keep your private keys safe by generating backups both online and offline.
Remember: Your wallet does not reside on any single device. The wallet itself resides on the Bitcoin blockchain, just as your banking app doesn’t truly “hold” the cash in your checking account.
While wallet apps work well and are relatively safe, the safest option is a hardware wallet you keep offline, in a secure place. The most popular hardware wallets use special layers of security to ensure your keys are not stolen and your bitcoin is safe. But, once again, if you lose the hardware wallet your bitcoins are gone unless you have kept reliable backups of the keys.
The least-secure option is an online wallet, i.e. storing your bitcoin in an exchange. This is because the keys are held by a third party. For many, the online exchange wallets are the easiest to set up and use, presenting an all-too-familiar choice: convenience versus safety.
Many serious bitcoin investors use a hybrid approach: They hold a core, long-term amount of bitcoin offline in so-called “cold storage,” while keeping a spending balance in a mobile account.
Depending on your bitcoin strategy and willingness to get technical, here are the different types of bitcoin wallets available. Bitcoin.org has a helper that will show you which wallet to choose.
Cloud wallets exist online and the keys are usually stored in a distant server run by a third party. Cloud-based wallets tend to have a more user-friendly interface but you will be trusting a third party with your private keys, which makes your funds more susceptible to theft. Some examples of this wallet type are Coinbase, Blockchain and Lumi Wallet. Most cryptocurrencies, including bitcoin, have their own native wallets. Some offer additional security features such as offline storage (Coinbase and Xapo).
With your private keys stored on a server, you have to trust the host’s security measures and also trust the host won’t disappear with your money or close down and deny you access.
Software wallets can be installed directly on your computer, giving you private control of your keys. Most have relatively easy configuration and are free. The disadvantage is you are in charge of securing your keys. Software wallets also require greater security precautions. If your computer is hacked or stolen, the thief can get a copy of your wallet and your bitcoin.
While you can download the original software Bitcoin Core protocol (which stores a ledger of all transactions since 2009 and takes up a lot of space), most wallets in use today are “light” wallets, or SPV (Simplified Payment Verification) wallets, which do not download the entire ledger but sync to it.
Electrum is a well-known SPV desktop bitcoin wallet that also offers “cold storage” (a totally offline option for additional security). Exodus can track multiple assets with a sophisticated user interface. Some (such as Jaxx Liberty) can hold a wide range of digital assets, and some (such as Copay) offer the possibility of shared accounts.
Before downloading any app, please confirm you are downloading a legitimate copy of a real wallet. Some shady programmers create clones of various crypto websites and offer downloads for free, leading to the possibility of a hack.
Mobile wallets are available as apps for your smartphone, especially useful if you want to pay for something in bitcoin in a shop or if you want to buy, sell or send while on the move. All of the online wallets and most of the desktop ones mentioned above have mobile versions, while others – such as Abra, Edge and Bread – were created with mobile in mind. Remember, many online wallets will store your keys on the phone itself, leading to the possibility of losing your bitcoin if you lose your phone. Always keep a backup of your keys on a different device and print out your seed phrase.
Hardware wallets are small devices that connect to the web only to enact bitcoin transactions. They are more secure because they are generally offline and therefore not hackable. They can be stolen or lost, however, along with the bitcoins that belong to the stored private keys, so it’s recommended that you backup your keys. Some large investors keep their hardware wallets in secure locations such as bank vaults. Trezor, Keepkey and Ledger are notable examples.
Paper wallets are perhaps the simplest of all the wallets. Paper wallets are pieces of paper that contain the private and public keys of a bitcoin address. Ideal for the long-term storage of bitcoin (away from fire and water, of course) or for the giving of bitcoin as a gift, these wallets are more secure in that they’re not connected to a network. They are, however, easier to lose.
With services such as WalletGenerator, you can easily create a new address and print the wallet on your printer. When you’re ready to top up your paper wallet you simply send some bitcoin to that address and then store it safely. Whatever option you go for, be sure to back up everything and only tell your nearest and dearest where your backups are stored.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

This is a seriously important topic everyone is ignoring. Copay / Bitpay wallet has been having problems with their servers. In long story short. TONS of transactions have just gone missing from users across the world. If you go onto the copay help and support forum, there's tons of new topics of people losing funds or them being in limbo in copays system. I have lost over 3k and support is ignoring everyone's tickets... How is no one talking about this ?
EDITED TO INCLUDE BACKSTORY FROM BELOW:
So on December 9th in my copay wallet right now, I am sending out 0.043239 BTC with a fee of 0.000243btc to address : 1LqRQgKFDKfm6za8q6esdU2yFYe1zngqJc with tx : 83309d5858cf226c3c0edd360c36a2c0c059db3da3a3582f47df6cd468bf2f80
Yes I understand this was a low fee, but I send transactions ranging from 400 sat/byte to 80 sat/byte depending on the situation.. it still should have been picked up on the blockchain and in the mempool at 88 sat/b
The reciever who is my brother, has the funds recieved into his wallet. Yet this transaction is not on the blockchain. When I view the transaction in copay it directs me to bitpay insight, which then states transaction does not exist. If I paste this tx into any block explorer it doesn't exist, and if I paste the address of my brother who is recieving the funds, on the blockchain, it says there has been no recieved Bitcoin to the address. On top of this, the balance that was sent out keeps appearing and revanishing in my wallet as if it is there for a second and then disappearing, as well as in my transaction history. I have screenshots and can demonstrate how there is something wrong with copay. This has nothing to do with the mempool.
My transaction did not even touch down in the mempool, but the balance sent out of my copay ? How does this make any sense.. The representative on the copay board keeps going in circles that he encourages us to paste a txid that isn't even real into a blockexplorer other than bitpay insight.. he is also closing all tickets without resolving this problem. By hand i can count 20 people with this issue. Someone even lost 9 btc. This is ridiculous.
Please do not give me the answer that the mempool is too full or this transaction does not exist.. because it does exist, and I'm missing a total of $1500 usd from my wallet which I can view as sent out but unconfirmed and not touching down on the blockchain. I have years of experience in this industry as well as run a business around it. I am familiar with fees / acceleration as well as bumping. And this is not something anyone should be dealing with. Where is my money and how are you going to resolve this.
Here is another user who lost 3 btc with copay with similar issues.. no one is talking about this...

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

Next on the Bitcoin Cash development roadmap: upgrading Address format on Jan 14th

next for bitcoin cash development: https://lists.linuxfoundation.org/pipermail/bitcoin-ml/2017-Novembe000472.html
upgrading the address format.
The C/H format is a copay workaround built on TOP of the protocol.
this would be a change in the code itself.
seems to be consensus on moving forward with this change.

Ok, now that Bitcoin.com Wallet supports BCH BIP70 transactions, it appears that it is currently the best wallet for doing Bitcoin Cash transactions with Bitpay merchants. Here's why...

A week ago, Bitpay (largest payment processor) rolled out Bitcoin Cash (BCH) support to 100,000+ merchants.
At the time of the rollout, the only wallets that supported BCH BIP70 transactions were the Bitpay Wallet & Copay Wallet.
But there's a problem: Bitpay Wallet & Copay Wallet only support BCH CashAddr & Copay address formats, and do not support the BCH legacy address format. Meanwhile, LedgeTrezoJaxx wallets ONLY support the BCH legacy address format. To send BCH back & forth between these wallets, people have to use an online tool to convert the address formats. Very awkward.
Now, it seems that Bitcoin.com Wallet has rolled out support for BCH BIP70 transactions.
I've briefly tried out both the Bitcoin.com Wallet and Bitpay Wallet, and it appears that Bitcoin.com Wallet is currently the best choice for doing BCH transactions with Bitpay merchants. Here's why:
Let me know your thoughts.
submitted by normal_rc to btc [link] [comments]

Ugh. It appears that Trezor Wallet only recognizes BCH "legacy" addresses, while Bitpay Wallet only displays BCH "cashaddr" or "copay" addresses. Use https://cashaddr.bitcoincash.org to do address format conversions.

Bitpay Wallet only dispalys BCH CashAddr or Copay format addresses, but not the Legacy format address.
But Trezor & Ledger & Jaxx Wallets don't support the new BCH CashAddr format.
And the Trezor doesn't support the Copay format address either. Ledger & Jaxx might be in the same situation.
What this means is that if you have a TrezoLedgeJaxx Wallet, and want to send BCH to a Bitpay Wallet, you'll probably have to use an online conversion tool to get the BCH Legacy address format.
u/spair , it's probably best for the Bitpay Wallet to have the option of showing BCH legacy format addresses, to make it easier to transfer BCH from TrezoLedgeJaxx Wallets to Bitpay Wallets.

Dash is not affected by the BitPay Copay attack

Good day everyone !
You might have seen the news on GitHub, Twitter, ZDNet, and various other places on the net. The whole JavaScript ecosystem discovered an attack targeting BitPay's Copay product.In order to be sure the compromised package was included in Copay during the building phase, the attacker had to spread an ingenious, obfuscated and malicious code across the whole ecosystem.This malicious code was looking for a description of a package (bunch of code that works as libraries to enhance programmer's productivity) that had the specific message, "A Secure Bitcoin Wallet", and used that as a decryption key to unveil and execute the dormant code.
This matched two projects: Copay, and our first fork of copay created 2 years ago while Dash was studying the idea of using Copay as a foundation for DashPay. We did not pursue this idea further, and that project was never used.
The Dash Copay Beta that we worked on and released was not targeted and therefore won't manage to steal your funds.

Here is the exact naming thing that got everyone (including ZDNet at one point) confused:
- dash-copay is the name of the repository for the Dash version of Copay, this one is not at risk for different reason (pkg description, different dependencies,...)- copay-dash: Is the library that was also at risk, because it was a fork that we did not even bother to Dashify, so raw, that's it's more a tag of a specific version of Copay that a fork. This one, no one has used (except for bots and researchers that downloaded it in recent days).

So, what happened ?
I’ve been looking at it, thanks to a message from Bitpay.
I want to first say how grateful I am to BitPay; they were blazing fast in sharing with us this information, which allowed us to get in touch with ZDNet and clear all suspicions on Dash.

And secondly for all the foundations they paved, theses packages remain open-source which means that if you do not maintain them, they get outdated, with issues and vulnerabilities. And in this case, I think that the Bitcoin community would benefit from grouping together and starting a Patreon (or forking our governance system) to fund some devs to be able to keep everything up-to-date, to be able to verify the dependencies, and to be able to improve and reduce their dependencies.

So that should be cleared up: This attack targeted everyone, people from React, Vue, Nodemon, from the Node Security team or the Google Security team, experts in their domain also didn't notice it, because it’s finding a needle in a haystack.So clearly, it's not about BitPay, but it’s good warning for all of us to improve our package dependency strategy and review processes.

On the 20th of November, a CS Student found that a package included some strange code. He found a code that he couldn’t really understand, but that is known by most of the crypto community devs (JS).He immediately understood that it was malicious, but it took the community time to get the information, and given the control that the attacker had, we are lucky he didn’t or couldn’t remove the GitHub issue...No fault on that--as a Student, did you know who to contact when you found malicious JS code? (FYI to all CS students: https://nodejs.org/en/security/ is also to be used for third-party vulnerabilities)

This code, present in a minified file, but not in the regular file (the one people actually read), was trying to decipher an aes256 ciphered message that was first turned into a hexadecimal string. The decryption key is the npm_package_description, all packages have one, but Copay specifically has "A Secure Bitcoin Wallet". How did they find that? Well, by iterating all packages descriptions available (and there are a lot of them).

When you enter this passphrase, you then get the code that is injected. This injection as explained before, targets your private keys, requires another package to do that (bitcore-wallet-client), and will then send that information to either:
- A domain bought using crypto and a throwaway email address: copayapi.host (cost: 0.99$/yr..)- If it doesn’t resolve, to a direct static ip (111.90.151.134) which resolves to a Malaysian Transit Service.

Because Dash Copay does not use `bitcore-wallet-client`, and doesn’t have the same description, we were not targeted. The attacker has targeted Bitpay Copay implementation having bch / btc. They didn’t care at all about trying to target other implementations like Dash.

This is a good reminder for us that our decision to limit our dependencies is the right one. It doesn’t help our productivity, but it will benefit the security of our Javascript libraries.

So in the end, this attack specifically targeted the BitPay Copay App from 5.0.2 to 5.1.0.

Introduction to Garlicoin

FAQs

What is Garlicoin?
Garlicoin is a community-based cryptocurrency that was originally founded based on a meme of garlic bread that reached the front page of Reddit. The concept of a memecoin is similar to that of the more well-known Dogecoin, but Garlicoin is actually a fork of Litecoin, which is itself a fork of Bitcoin.
What technology is behind Garlicoin?
As it's just a fork of Litecoin, it's basically the same thing with how the addresses, wallets, etc. work but there are a few key differences. Most importantly, the mining algorithm is called "Allium," which was specially developed to be ASIC-resistant. Originally the coin was based on Scrypt-N but a hard-fork occurred on 2/16/2018 in order to solve the problem of ASICs that were discovered on the network. Another key difference is that Garlicoin only has a 40 second block time, so transactions confirm very fast.
Who developed Garlicoin?
Disclaimer: Most of the code was copy-pasted. However, there are a few developers that continue to work on the project. u/DigitalizedOrange was the founder, he likes anime. Most of the moderators are also part of the team.
Should I invest in Garlicoin?
Like any cryptocurrency, don't treat it as investing. Treat it like speculation or gambling. If you're not willing to lose that money, the answer is no. Garlicoin has even more risk behind it as it isn't trying to be at the forefront of technology or anything. All we have is meme appeal and garlic bread.
Why did the price just moon? Or why did it just crash?
With such a low volume in Garlicoin exchanges, the price can be easily manipulated. Trade with caution.
How can I start mining?
Check out the mining section in the links and tutorials down below. There's a great guide to setting everything up by Pandawan.
Why does the explorer show a different value than my web-based wallet?
Some web-based wallets, such as GarlicWallet.com, are shared wallets meaning that you don't own the private keys and the website will move your coins around between addresses. The address you receive just credits your online account so you can withdraw a specific amount however you technically do not own those coins and if the site goes down then you may lose access to them forever. For that reason, it's highly recommended that you use a wallet where you own the private keys. Paper wallets are the most secure for large values as long as you physically keep them in a safe place, as they cannot be hacked.
What other Garlic Bread goodness can I get into?
Check out GBDS (dating simulator) and GarlicBreadMemes if you can't get enough.
I have another question that isn't answered here!
First try using the search bar for this subreddit. If you can't find an answer then you can create a new thread and someone from the community will most likely help you. If I forgot to add a commonly asked question to this guide, or if there's anything else you'd like to see explained/linked here, please let me know in the comments.

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.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For lots of additional video resources check out the videos wiki page or /BitcoinTV.
Key properties of bitcoin
  • Limited Supply - There will only ever be 21,000,000 bitcoins created and they are issued in a predictable fashion, you can view the inflation schedule here. Once they are all issued Bitcoin will be truly deflationary.
  • Open source - Bitcoin code is fully auditable. You can read the source code yourself here.
  • Accountable - The public ledger is transparent, all transactions are seen by everyone.
  • Decentralized - Bitcoin is globally distributed across thousands of nodes with no single point of failure and as such can't be shut down similar to how Bittorrent works.
  • Censorship resistant - No one can prevent you from interacting with the bitcoin network and no one can censor, alter or block transactions that they disagree with, see Operation Chokepoint.
  • Push system - There are no chargebacks in bitcoin because only the person who owns the address where the bitcoins reside has the authority to move them.
  • Low fee - Transactions fees can vary between a few cents and a few dollars depending on network demand and how much priority you wish to assign to the transaction. Most wallets calculate the fee automatically but you can view current fees here.
  • Borderless - No country can stop it from going in/out, even in areas currently unserved by traditional banking as the ledger is globally distributed.
  • Trustless - Bitcoin solved the Byzantine's Generals Problem which means nobody needs to trust anybody for it to work.
  • Pseudonymous - No need to expose personal information when purchasing with cash or transacting.
  • Secure - Encrypted cryptographically and can’t be brute forced or confiscated with proper key management such as hardware wallets.
  • Programmable - Individual units of bitcoin can be programmed to transfer based on certain criteria being met
  • Nearly instant - From a few seconds to a few minutes depending on need for confirmations. After a few confirmations transactions are irreversible.
  • Peer-to-peer - No intermediaries with a cut, no need for trusted third parties.
  • Portable - Bitcoins are digital so they are easier to move than cash or gold. They can even be transported by simply remembering a string of words for wallet recovery.
  • Scalable - Each bitcoin is divisible down to 8 decimals allowing it to grow in value while still accommodating micro-transactions.
  • Designed Money - Bitcoin was created to fit all the fundamental properties of money better than gold or fiat
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin 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 Cashila or 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.
  • If you prefer to "Be your own bank" and have direct control over your coins without having to use a trusted third party, there are many software wallet options here. If you want easy and secure storage without having to learn computer security best practices, then a hardware wallet such as the Trezor or Ledger is recommended. A more advanced option is to secure them yourself using paper wallets generated offline. Some popular mobile and desktop options are listed below and most are cross platform.
Android iOs Desktop
Mycelium BreadWallet Electrum
CoPay AirBitz Armory
  • If you prefer to let third party "Bitcoin banks" manage your coins, try Coinbase or Xapo but be aware you may not be in control of your private keys in which case you would have to ask permission to access your funds and be exposed to third party risk.
Another interesting use case for physical storage/transfer is the Opendime. Opendime is a small USB stick that allows you to spend Bitcoin by physically passing it along so it's anonymous and tangible like cash.
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, usually from a text message or app, 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.

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. Bitseed is an easy option for getting set up. You can view the global node distribution here.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin ?BTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (?L) or micrometre (?m)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:
  • 0.02 BTC
  • 20 mBTC
  • 20,000 bits
For more information check out the Bitcoin units wiki.

Welcome to the /Bitcoin Sticky FAQ

Maybe you're here because you've received a tip on social media, or maybe you've just been hearing a lot recently about Bitcoin and are wondering what the big deal is? The following videos are a good starting point for understanding how bitcoin works and a little bit about its long term potential:
For lots of additional video resources check out the videos wiki page or /BitcoinTV . Peer-reviewed, research papers can be found here.

Where can I buy bitcoins?

You can buy or sell any amount of bitcoin (from as little as $1 worth) and there are several easy methods to purchase bitcoin with cash, credit card or bank account. A good list of exchanges sorted by region can be found on the exchanges wiki here.
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. Here are a couple useful sites [bitkoin.io, preev.com] that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Where can I spend bitcoins?

Securing your bitcoins

With bitcoin you can "be your own bank" and personally secure your bitcoins OR you can use established companies such as Coinbase and Circle which have secured wallets where they hold the bitcoins for you and provide insurance.
If you prefer to "be your own bank" and have direct control over your coins without having to use a trusted third party, there are many options in the wallets wiki. If you would prefer easy and secure storage without having to learn computer security best practices then a hardware wallet such as the Trezor, Ledger or HW-1 is recommended.
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, usually from a text message or app, making it much harder for thieves to gain access.
Google Authenticator Authy

Earning bitcoins

Just like any other form of money, you can earn bitcoins by working for them. Here are a few resources for bitcoin jobs.

No Treasury proposal for it exists.
  19. 10 Stupid Things People Say About Dash And How To Respond
  20. Sporks: One of the foundations of Dash's success
  21. There is no so called "Master Private Key" in Dash and there never has been. Sporks (explained above) have no relation to user funds, as the source code easily proves.
  22. Trolls vs. Users: The Limited Importance of Online Communities
  23. Dash PrivateSend and usage of denomination inputs
  24. Valuable link list from Dash Force member Mastermined
  25. "But Dash PrivateSend has a much smaller ambiguity set! Its privacy is broken!!!"
  26. Succinct refutation on Masternodes "artifically" blowing up the price & Evan Duffield being the only miner at launch
  27. Bitcoin Cash vs Dash
  28. "Dash rebranded from Darkcoin to distance itself from its dark history!!" -> Not at all. Nothing about its history is "dark" and more importantly this thread called "The Birth of Darkcoin" is stickied by Evan Duffield himself on the official main forum.
  29. "Evan Duffield lied about the launch time so he would get an unfair advantage at mining!" -> Quotes from the original launch thread on Bitcointalk: "Awesome! We'll be launching soon. Things are looking good." and "Launch is being moved to 11PM EST!". As the genesis block proves launch took place at 03:54:41 AM (UTC) on Jan. 19th, 2014 or 10:54:41 PM (EST), Jan. 18th, 2014. So if anything it was 5 minutes early.
  30. "But Litecoin is superior to Dash!!" - Really? Let's compare - Here's another sober look at the facts on this issue.
  31. Why Dash is not prone to cluster analysis attacks
  32. How "centralized" is Dash, really? & Which project is actually centralized here?
  33. From the day Dash started trading until late April 2014 anyone had the chance to buy Dash for less than 1 USD
  34. Dash Core developer MooCowMoo on alleged Masternode centralization and PrivateSend
  35. Why Masternodes have no incentive to vote in a proposal to pay themselves a large sum of Dash
  36. What is Dash's competitive edge?
  37. Why saying "Dash is a company" is false: Dash Core Inc., a company based in Scottsdale, Arizona is not the decentralized network called Dash. The network, consistent of over 4.5k globally distributed, decentralized Masternodes decided to hire and fund the company Dash Core Inc. to develop said network. This is the distinguishing property of Dash being a DAO, so it's understandable people have difficulty grasping the concept. Similarly Dash does not have a CEO, while Dash Core Inc. -obviously- has.
  38. Dash does not and never had a "dev tax": Dash has a Treasury and its distribution is being voted on each month. Only those funds that have been approved by the Masternode network go to proposal owners. The Treasury is capped at 10% of the accumulated block reward of one month. There is no central authority non-requested or non-approved funds go to and there never has been. Those funds are simply not created. So you can have months in which only 8% of the budget is being paid out, with the remaining 2% going to nobody due to not being mined.
  39. "B-but Evan Duffield can roll back the last 24 hours of the blockchain with the flick of a button!" Complete bullshit. The key in question refers to requiring a Masternode to re-validate its pre-existing blockchain in order to ensure it's on the right chain. Masternodes have nothing do with putting or removing transactions into or from the blockchain, only the miners can do that, thus claiming someone can "roll back the blockchain" in Dash is a malicious lie and a desperate attempt to make Dash look centralized when it's not. In short: No such button exists, ever existed or will ever exist.
  40. Why the total coin supply was changed or "The 84 million coin"-Question

General notes:

The Dash community is well aware that during most of its history this project has been under attack by competitors, many of which are trying to portray Dash (among many other things) as a failure. This is oxymoronic, because nobody hates on failures, especially not for 4 successful years in a row.
If you want a quick history lesson, here's a comment I made on where the Dash hate originated from back in 2014
Another, longer history lesson
Remain skeptical towards sensational accusations without evidence. Our community is helpful, knowledgeable and more than happy to answer any questions, as we have done many times on this subreddit. Still, we're all only human, have limited resources and we're just one project among many (always among the top, though!). Stakeholders and investors of other projects will always have an agenda to smear what they perceive as competition (I have yet to see our community actively go after other projects, though).
Just remember the Bullshit Asymmetry: "The amount of energy required to refute bullshit is at least an order of magnitude larger than to produce it." So it would be very unjust to expect a refutation on the spot all of the time. Prefer taking the initiative by asking the community directly about the claim you're confronted with. This community has proven many times to possess the integrity required to admit to technological shortcomings, but at the same time we'll never hesitate to call out illegitimate claims and accusations, of which there are many, for what they are.
The most common and most empty attack is "Dash is a scam".
More importantly you have to ask the critic just this one question: Who was scammed? The answer usually consists of complete silence or attempts to change the topic. This may sound all very defensive to someone who has never experienced the kind of FUD Dash has faced over the years, but the falsehoods we've refuted above are still being perpetuated by a very lonely but also very loud minority.

Not an ICO project

Regarding Dash's finances: Despite what many people assume influenced by the ICO insanity of the recent past, Dash did not have an ICO and Dash does not depend on 3rd party funding/investors. It is self funded from the blockchain and thus an entirely independent organization that does exactly what it wants, not what any angel investors want us to do. Dash is the first currency in history to achieve that.

Quick incomplete rundown of Dash's features

In fact Dash pioneered almost every single one of its features making it one of the most prolific innovators in the cryptocurrency space. Before Dash invented them, none of these features existed:
To re-iterate a previous point:
Dash has been copied by several dozen other projects either completely or through selected features indicating a strong approval of its technology within the wider cryptocurrency industry. The most copied feature by far is the Masternode system and the financial self-reliance it provides.
