The most complete collection of Bitcoin & Crypto Vocabulary! The Crypto community has developed a vocabulary of its own and it can be a bit confusing in the beginning, but don't worry, after reading this you will most probably be a bit more fluent in the jargon of the Bitcoin lingo.
Address or public key — Your Bitcoin address can be likened to your bank account number or e-mail. This is the only information required to receive payment in Bitcoins. It is important to note that for every transaction a different address should be used.
Accumulation — Accumulation means to buy as many coins as possible at the lowest possible price. It is often claimed that →Whales projects →fudden to accumulate as many coins as possible at a low price.
Airdrop — An Airdrop refers to the distribution of free → coins. New projects sometimes give away some of their coins to promote their product. For some Airdrops you have to actively do tasks to get them. Sites like Airdropking are specialized in finding the latest Airdrops.
Altcoin — any cryptocurrency that isn’t bitcoin. Yes, I do mean ANY!
Antminer — An antminer is a popular mining hardware, produced by →Bitmain.

B2B — B2B is an abbreviation for business to business, in contrast to →P2P or →Peer to Peer
Bearish — an expectation of when the price is set to decrease.
BearWhale — The so-called BearWhale is a user unknown to date, who owned at least 36,000 Bitcoin in the years 2013 / 2014. According to his own account, a large part of his lifelong savings was invested at a price of about $8 per BTC. He HODLed these Bitcoins for a long time until the discussion about reducing the blocksize shook his confidence and he decided to sell. On a memorable day in 2014 (October 5), he finally sold 30,000 BTC in a block! at a price of $300 over Bitstamp. This event became famous in the crypto community as the “Battle of BearWhale”.
Bit — It’s a sub-unit of a single bitcoin. One (1) bitcoin (BTC or B⃦) equals a million bits (1,000,000bits). This makes for ease of transacting with goods and services.
Bitcoin — When communicating Bitcoin as an idea, the first letter is capitalized. For example a sentence like — “Let us discuss the process of Bitcoin mining at lunch”.
On the other hand, bitcoin without capitalization represents a unit of account. For example — “Did you get the 3 bitcoins Trevor sent you?”
Bitcoin (maximalist) — Bitcoin (BTC) is the oldest → cryptocurrency. It was developed by → Satoshi Nakamoto. Bitcoin is currently the → cryptocurrency with the highest → market capitalization. A Bitcoin maximalist only accepts Bitcoin as the “one, true” → cryptocurrency
Bitcoin cash — Bitcoin Cash (BCH) is a → hard fork of Bitcoin, which promises to increase the → transaction speed of Bitcoin and additionally reduce the → mining fees by increasing the → block size. Increasing the block size has advantages and disadvantages, and it remains to be seen whether this approach is a sensible approach for → scaling. Bitcoin Cash has not activated → Segwit and does not intend to scale with the → Lightning Network. Bitcoin Cash and Bitcoin both want to bear the name “Bitcoin” and the ticker symbol BTC, since they both claim that they represent the “real” vision of Bitcoin, created by → Satoshi Nakamoto. One of the most influential Bitcoin Cash supporters is → Roger Ver
Bitcointalk — Bitcointalk is the largest discussion forum for cryptocurrencies.
Bitfinex — The Bitfinex is a → cryptocurrency exchange on which → Fiat can be exchanged for → Crypto.

Block Reward — Number of coins →Miner receives for publishing a valid →Blocks if it becomes part of →Blockchain
Binance — Binance is one of the largest →cryptocurrency exchanges.
Block — This is a collection of transactions records in the blockchain that confirms a lot of pending transactions. At approximately every 10minutes, a new block of transactions by the process of mining gets added to the blockchain.
Blockchain — blockchain’s are distributed online ledgers, that are secured by cryptography. Look at them like public databases that anyone can access and read, however the data can only be updated by the owners. Also note, the data is copied and resides across thousands of computers worldwide. For a more in depth explanation, check out — https —//en.wikipedia.org/wiki/Blockchain
Blockfolio — A popular app to track the current exchange rate of crypto currencies.
Block size — Denotes the size of a → block. Usually the size of a block is between a few kilobytes and a few megabytes. Some cryptocurrencies prefer to have a fixed, small block size (→ Bitcoin), while others prefer to use a larger block size (→ Bitcoin Cash). Some cryptocurrencies use a dynamic block size that can change over time (→ Monero). Still other cryptocurrencies like → IOTA or → Nano don’t have conventional block sizes because they don’t use blockchain technology. A larger block means that more transactions can be accepted per unit of time, which reduces the → transaction fees and empties the → mempool more quickly. However, large blocks make the → blockchain grow faster, which can lead to → centralization, since fewer people are willing to operate a → full node. Different perspectives on the block size has led to the → hard fork between → Bitcoin and → Bitcoin Cash.
Block Lattice — Block Lattice is an alternative data structure, which promises some advantages over the block chain. For example, a block lattice allows faster →transactions for fewer fees. The block lattice works fundamentally differently than the →Blockchain. This data structure is currently used by the crypto currency →Nano.
Block time — The average time it takes to publish a block. Longer block times result in a lower transaction speed.
Blox — A popular app to track the current exchange rate of cryptocurrencies.
Bounty — Some →ICOs pay people to find bugs, translate documents and promote the ICO. The payment for these activities is often called bounty

BTC —This is the token symbol for representing Bitcoin.
Bullish — an expectation that price is going to increase.
Bubble — A bubble occurs when the prices of a commodity (here — crypto-currencies) in the market significantly exceed the intrinsic value of this commodity. Bubbles can “burst” at any time within a very short time, which causes a →bear market to be created.
Burning — Burning crypto-currencies means sending them to an address that is/can’t be controlled by anyone. They are effectively destroyed and removed from circulation forever.
Buywall — A high demand of crypto currencies at a certain price. A buywall graphically appears as a high vertical wall on the bid side in a depth chart.

Confirmation — This implies a hand shake i.e. a particular transaction has been sorted out by the network, added to a block of transactions and are most likely irreversible. Transactions receive a confirmation when they are included in a block and for each subsequent block. For low value transactions, a single confirmation may be considered to be secured, however waiting for 6 confirmations or more when dealing with huge volume of Bitcoins is considered best practice. The more confirmations that get stacked on top of your blocks’ transaction, the less the risk of getting your transaction reversed.
Cryptographic Signature — A particular Bitcoin wallet and its corresponding private key are connected via cryptographic wizardry. Using an appropriate private key, your Bitcoin wallet signs a transaction, which is easy for the entire network to validate that the amount of Bitcoin being sent corresponds to your signature. The magic here now is the impossibility of guessing your private key.
Cryptography — This is a branch of mathematics that helps establish tamper evidence, providing a high level of security. Software version control tools, banking and ecommerce already make use of some form of cryptography. The Bitcoin blockchain is built on cryptographic hashes, which culminate into an ever growing blockchain ensuring tamper evidence and tamper proof on the network.
Craig Wright — Also known by the nickname →Fake Satoshi or →Faketoshi is a well-known →Bitcoin cash advocate. Craig Wright himself says that he is →Satoshi Nakamoto, but he has not been able to prove this beyond doubt until today. Many people, including →Vitalik Buterin doubt very strongly that Craigh Wright is Satoshi.
Crash — A very sharp drop in prices.
Crypto(currency) — Cryptocurrency.
Crypto Kitties — Cryptokitties is a popular →dApp on the →Ethereum →Blockchain
Double Spending — The double spending problem has been a major issue with previous digital currencies, where an unscrupulous user tries to manipulate the system by transacting their Bitcoins to different recipients at the same time.

Decentralized — In a decentralized system, the users are linked to each other via →P2P. There is no central authority, with special privileges. Anyone can join a decentralized network, it is difficult to take offline and – in the best case – almost impossible to hack. A real decentralized network is →trustless. Decentralized autonomous organization — A decentralised autonomous organisation is an organisation which is regulated by →Smart contracts. The idea of a DAO comes from →Dan Larimer. The hack of the Smart Contracts of the first decentralized autonomous organization ́The DAO ”. Leads to →Hard Fork of the →Ethereum network. The hard fork is now known as →Ethereum, the old block chain where the hack is still present is known as Ethereum Classic.
Decentralized exchange — A →stock exchange, which is regulated by →Smart Contracts. Decentralized exchanges are in theory cheaper and safer than centralized exchanges. Unfortunately they often have less good design and little Trading→Volume

EOS — EOS is the name of a crypto currency that uses →Dan Larimer’s →dPOS. It is a direct competitor of the →Ethereum network. EOS promises free and fast transactions and →Smart contract functions.
ERC-20 token — ERC – 20 Token (Ethereum Request for Comment) is a set of standard program code often used to create personalized →Token on →Ethereum →Blockchain as part of a →Smart contract. This functionality is often used by →ICOs. All these tokens can be used in Ethereum compatible →Wallets. Since these →Token use the Ethereum blockchain, you need Ethereum to pay the →Transactions fees for sending the tokens.
Escrow — Escrow payment means that the coins are held by a third party until both the buyer and the seller signal that the purchase/sale has gone smoothly. If there are any problems with the transaction, the third party will decide whether the buyer or the seller will get the money back.

Eth(ereum) — ETH is the →Tickersymbol of Ethereum. Ethereum is the second largest crypto currency. The founder of Ethereum is →Vitalik Buterin. Ethereum is the largest platform. Most →ICOs are launched on the Ethereum Blockchain. The Ethereum Blockchain hosts many →dApps and →Smart contracts. →Smart Contracts must be written on the Ethereum Blockchain in the programming language →Solidity. The consensus algorithm is →POW and not →ASIC resistant. However, the →Casper update will cause an →Hardfork of the Ethereum network and then make Ethereum a →POS block chain. The →Blockzeit is faster than the block time of →Bitcoin. The currency of the Ethereum block chain is Ether.
Etherscan — Etherscan is a popular →Ethereum →Blockchain explorer. A software that allows you to search the Ethereum block grove for transactions
Exit scam — Exit scamming (= cheating by running away). Exit scammers get people to give them money. Mostly they promise the money lenders fantastic profit expectations. However, these profit expectations are not fulfilled. On the contrary, the exit scammer runs away – goes abroad – and steals the whole investment. Many →ICOs were exit scams

FUD — Fear, Uncertainty, and Doubt. Another negative based emotion spread intentionally by the media or a group of people within the crypto sphere that are typically looking to cause a price to drop, in hopes that they can purchase the cryptocurrency at a discount.
FUDster — anyone who is intentionally spreading FUD.
Fungibility — Fungibility. The property that coins cannot be assigned to a previous owner and are therefore 1 —1 interchangeable. →Monero has this property.
Fullnode — Node, which has downloaded and recalculated the whole blockchain.
Gains — Profit (in cryptocurrencies)
Gas — Gas is the name of a cryptocurrency that is needed to send tokens on the NEO platform. Gas is generated by holding NEO in a compatible → wallet. Gas also refers to the → transaction fees in → Ethereum. Gas is paid in → Gwei. Before you can make a transaction you have to decide how high the gas limit for the transaction should be. Gas limit is the maximum number of Gwei that you want to spend on the transaction. Complicated calculations require a higher gas limit. Increasing the gas limit will not make the Ethereum transaction faster.
Github — A popular website for uploading computer code and working together on it.
GPU — Graphics processing unit is a hardware part in a normal computer. GPUs are usually more powerful than CPUs and are therefore sometimes still used for →Mining, especially in coins that are →ASIC-resistant.
Gwei — 1 Gwei denotes 0,000 000 001 (1×10^-9) ether. 1 Gwei is therefore 10^9 Wei. The →Gas price is paid in Gwei and increasing it enhances the speed of a →Ethereum transaction.

Sometimes hard cap also refers to the maximum number of coins that can ever be put into circulation. For example, the hardcap for →Bitcoin is approximately 21 million BTC.
Hard Fork — new blockchain software that is non-backwards compatible. This causes a cryptocurrency to split into 2 separate currencies.
Hardware wallet — A hardware wallet is an electronic device that can create and store keys offline →Private . This method of storage is one of the most secure. Only using a →Paperwallets can be considered more secure. However, hardware wallets are much easier to use. Therefore, unlike paper wallets, they can also be used in everyday life. Paper wallets are more suitable only for →cold storage. The two best known hardware wallets are the Trezor and the Ledger Nano S. There are also e.g. Keepkey and CoolWallet S.
Hash Rate — The processing power of the Bitcoin network has a unit of measurement called a hash rate. In order to ensure security of the Bitcoin network, intense mathematical operations must be carried out by the network. At a hash rate of 10 Th/s, you would expect 10 trillion calculations per second.

Mining (pool) — Mining is the process of finding a correct solution of the →Hash(function) in a →POW network. People who actively participate in guessing an accepted solution of the hash function are called miners. If a miner is successful, he can publish a valid →Block. In return he (or she) receives in compensation and the miner reward (a certain number of newly created coins). In principle, anyone can become a Miner, but for most people it will not be financially rewarding. In →POW currencies, mining secures the network from attacks. A Mining Pool is a collection of miners who work together and share the reward among themselves.
Mining — This is a process performed by special nodes on the Bitcoin network called miners. It involves them competing against themselves to solve a computationally intensive cryptographic puzzle in order to decide who gets to add the next block of transactions to the blockchain, as well as securing the network.

Ponzi scheme — A fraudulent system in which victims are encouraged to invest in an → ICO or company that does not conduct a legitimate business, but only by making a profit to find more and more lenders. So the system builds on exponential growth and will implode over time and will not be able to pay off many investors.
POS — Proof-of-Stake (POS)
POW — Proof-of-Work (POW)
Premine — A premine (pre-mining) takes place if a developer sends a certain number of coins to his own address before the blockchain is made public. Premine can be fraudulent, but it can also be seen as a means of paying for development and listing on exchanges.
Privacy (coin) — Privacy coins usually use a → bitcoin-like ledger system, but add technology that obscures the path of the transaction. → Monero and ZCash are popular examples.
Private Key — This is for your eyes only secret piece of alphanumeric data which proves your right of ownership to spend Bitcoin from your Bitcoin wallet. It can be likened to your Bank vault combination lock. Private keys are either stored on a remote server for web/app based wallets; stored on your computer for software wallets; or they can even be printed on a piece of paper or metal. There specially designed hardware wallets that are similar to flash drives.
Proof of stake — Proof-of-stake (POS) is a consensus algorithm in which the amount of coins you have is directly related to the probability that you can publish a block. Proof of Stake is very environmentally friendly compared to Proof of Work. There is no mining at Proof of Stake.
Proof of work — Proof of Work is a consensus algorithm to achieve global → consensus. This algorithm is used by → Bitcoin and other cryptocurrencies. With proof of work, → miners calculate various → hashes with high energy consumption.
Public key — A public key is a cryptographic key that can be shared publicly without any problems. Transactions are often sent to the public key. It is important never to confuse the private key with the public key. The public key can be thought of as the address of a mailbox for which the private key is the key to unlocking it.
Pump — With a pump, a few → Whales (a less liquid) coin ask very strongly in a short time, which results in an immense price increase.
Pump and dump — A → pump and → dump is a scam that requires a group of investors to buy a certain (less liquid coin) at the same time. As soon as uninitiated investors start to develop → FOMO and invest in the coin due to the price increase, all the initiated investors start selling off their previously purchased coins. This sale in turn leads to a drop in prices. The portfolio of uninitiated investors often lose a large amount of value in a very short time.

Shitcoin — Shitcoin is a derogatory (but sometimes sarcastic / lovingly-meant) collective term for all “useless” coins. Bitcoin maximalists often unironically refer to all coins, except Bitcoin, as Shitcoin.
Short — If a position is “short”, it makes profit when the price drops
Short squeeze — A short squeeze is a rapid rise in price that occurs when there is a shortage of supply and excess demand triggered by people who have an open short and are forced to buy back the coins to minimize their losses, which is what Price keeps going higher and higher.
Side Chain — A sidechain is a separate blockchain that is linked to a mainchain.
Sign — Before you can send a → transaction you have to sign it with the → Private key. In wallets, this often happens automatically in the background.
Smart contract — Smart contracts are self-executing contracts in which the conditions are stored as snippets of code on the blockchain. Smart contracts, once published, cannot be changed again. Bugs in smart contracts can therefore have devastating consequences.
Softcap — Softcap is the minimum amount of capital that an ICO would like to collect to start the project
Softfork — A soft fork is a rule change (update) of the node software. A “soft fork” will not create “new” coins, since a soft fork is fully backward compatible.
