The Glossary of Cryptocurrency Terms

1BlockA block is a computer file that retains a record, or ledger, of bitcoin transactions completed during a specific period and is worth a certain amount of coins. One block in the Bitcoin network, for example, is worth 6.25 Bitcoins, a value that will halve every four years until the last block is created in 2140. The size of a block varies according to the blockchain. The theoretical limit for Bitcoin is 4MB, but Bitcoin Cash enables anything from 8MB to 32MB.
2BlockchainA decentralized computer network consists of autonomous yet connected blocks, copies of which are distributed throughout the network. When one or more Bitcoin transactions are added to a block, a new block is formed, and the transaction is verified and updated across the blockchain.
3Distributed Ledger A blockchain is also known as a ledger.
4Genesis Block Unspendable coins are contained in the first block of a blockchain. The genesis block of Bitcoin was produced on January 3, 2009, with 50 Bitcoins.
5Block Height A blockchain's total number of connected blocks.
6Peer-to-Peer The direct connection of two or more computers to each other without using a centralized third-party middleman. Blockchains are decentralized networks that function on peer-to-peer networks.
7ProtocolThe program connects the blocks and establishes the rules for adding new blocks to the decentralized network.
8AlgorithmThe algorithm or method for generating keys that keep transactions secure. Hash, Public Key, and Private Key are the three main keys that cryptocurrencies rely on (see below).
9EncryptionAn algorithm is used to turn legible text into illegible text, referred to as a hash or a key. The term cryptocurrency comes from this procedure, which is also known as cryptography.
10HashA verified and a string of letters and numbers represents the submitted transaction. It's commonly referred to as Hash or TxID.
11Hash Rate The rate at which a computer verifies and submits a transaction, creating a new Hash in the process. It is the average speed at which a blockchain generates new hashes, and it is measured in hash/second.
12Public Key A string of letters and numbers identifies the address of your wallet in the Blockchain. Like your email address or bank account number, this information can be shared with others to obtain cryptocurrency.
13Private Key A combination of letters and digits allows you to access your wallet. Like your password or PIN, this is private information that should never be shared.
14Seed Phrase A 12-, 18-, or 24-word phrase that only you and you alone know and that serves as a backup to your private keys. A seed phrase will help you recover your private key if you forget or lose it.
15WalletA blockchain file that receives and keeps your bitcoin, similar to how your email inbox receives and stores emails. Both a Public Key and a Private Key are used to operate it.
16Cold Wallet The offline storing of your wallet's Public and Private Keys by printing them on a piece of paper or putting them on an external hard drive that is not connected to the internet to avoid hacking loss. When you have a significant number of coins in your wallet, cold storage is recommended.
17Hot Wallet Your wallet's public and private keys are saved on an app connected to the internet and used to access it. If your computer or phone is hacked, your keys could be stolen.
18MiningThe process of a computer or a collection of computers verifying transactions. Two things happen when all of the computers accept the transaction on the network: a new block is added to the chain, and new coins are minted and added to the new block.
19ConsensusThe procedure for verifying and submitting transactions. Proof of Work (PoW), Proof of Authority (PoA), and Proof of Stake are the three basic forms of consensus algorithms (PoS).
20MempoolA "waiting area" for valid blocks is a group of validated and submitted transactions awaiting confirmation by all computers in the Bitcoin network. Congestion is indicated by a large mempool size, which signals a backlog of blocks waiting to be added to the blockchain.
21Proof of Work (PoW)Multiple computers in a blockchain compete to mine blocks using this algorithm. Before all other computers approve the new block in the blockchain, the first computer to mine a block must prove that it consumed a particular amount of energy to do so.
22Proof of Authority (PoA) An algorithm that grants authority to mine blocks to a trusted computer or a group of trusted computers. This method is substantially faster than PoW.
23Proof of Stake (PoS)A method that allows a computer to mine blocks based on the number of bitcoin it has. For example, a machine with 2% of the coins available can only mine 2% of all blocks.
24Proof of Activity (PoA)An algorithm verifies transactions using both Proof of Work (PoW) and Proof of Stake (PoS) after a block has been successfully inserted, the system shifts from PoW to PoS.
25Proof of Burn (PoB) A method for computers to mine blocks based on the number of coins they "burn." Sending coins to an unspendable address causes them to be burnt. The more coins that are burned, the more opportunities there are to mine.
26Non-Fungible Token Each NFT is unique as a fingerprint because it is stored within a block and cannot be copied or altered. This is why NFTs are used to prove ownership of digital assets, such as a JPEG image or a digital painting, or to grant access to the item.
27Fiat Currency Government-issued money is circulated through banks. On the other hand, cryptocurrencies are created by computers and circulated through a peer-to-peer network or blockchain.
28NodeA blockchain computer is a computer that is a component of the blockchain network. As a result, a blockchain is a network of nodes.
29FaucetA website or program rewards users with free cryptocurrency in exchange for joining up or completing certain tasks. Some (but not all) of these offers are scams, so be cautious before signing up or sharing any personal information.
30WhaleIndividuals or organizations who own a large number of a cryptocurrency's coins. The minimum number of coins required to qualify as a Whale in Bitcoin is 1,000. A Dolphin or a Fish is a smaller holding.
31NonceA one-time-only random number is created and used to verify fresh blocks. When a block is submitted, it is given a nonce to ensure it is a new block and not an old one re-submitted to the chain.
32Smart Contracts Lines of code that reside on the blockchain and are used to carry out the logic that the developer has designed. When data is sent to the blockchain, the code does what it is supposed to do, such as making a dividend.
33SolidityThe programming language that Ethereum-based smart contracts are written in.
34OracleA code that collects data from various sources both inside and outside the blockchain validates analyses and feeds the results into a smart contract for further action. Smart contracts rely on oracle data to carry out their tasks.
35TokenA coin that symbolizes an asset or has a specialized application in the blockchain ecosystem. Some tokens are used for governance, allowing token holders to vote on blockchain developments.
36Chain Linking The process of connecting two separate Blockchains, such as Bitcoin and Ethereum, to move cryptocurrencies between them. The transaction must be recorded and verified in both blockchains simultaneously for it to be successful.
37Block Explorer A blockchain search engine that allows you to engage in blockchain transactions and access blockchain data. Blockchain.com, blockstream.info, blockexplorer.com, blockcypher.com, and btc.com are other examples.
38Application-Specific Integrated Circuit (ASIC) A dedicated circuit created for machines that solely mine one sort of cryptocurrency and do nothing else. Only Bitcoin can be mined with a Bitcoin ASIC circuit, not Ethereum.
39AltcoinsBecause Bitcoin was the first cryptocurrency, any cryptocurrency that isn't Bitcoin is referred to as an altcoin (such as Ethereum, Litecoin, and Cardano). There are thousands of altcoins, some of which are lawful and others used as financial crime conduits.
40Decentralized Finance (DeFi)A financial service that uses blockchains and smart contracts to make financial and banking services more accessible. Because DeFis are automated, they give everyone access to services previously only available to a select few.
41ExchangeA website that allows you to exchange cryptocurrencies for fiat currencies such as dollars or euros and fiat currency for cryptocurrency and cryptocurrency for cryptocurrency.
42BitcoinThe very first digital currency. It was the first cryptocurrency to be released in 2009, and it is still the most valuable and largest cryptocurrency today.
43SATSBitcoin's smallest unit, equivalent to 0.00000001 BTC. Satoshi Nakamoto, the putative founder of bitcoin, is referred to as Satoshi.
44EthereumEthereum is a blockchain with its cryptocurrency, Ether. Unlike the Bitcoin blockchain, Ethereum allows decentralized programs to be built on top of it, allowing Ethereum to go beyond mining to include decentralized financial services, gaming, and a variety of other decentralized applications.
45Ether (ETH)The Ethereum network's native cryptocurrency. Ethereum, on the other hand, accepts a variety of cryptocurrencies, including Bitcoin.
46GweiThe Ether's smallest unit. 0.000000001 ETH is equal to 1 gwei (10-9 ETH). As a result, one ETH is equal to one billion gwei.
47GasA miner's charge for validating and submitting transactions on the Ethereum network. The requirement of Gas for each transaction protects Ethereum from becoming clogged with invalid transactions.
48dApps (Decentralized Apps)Applications or programs that run on a blockchain and are not controlled by a central authority. If Twitter became a dApp, no one, including Twitter, could erase a message after it was posted.
49Unspent Transaction Output (UTXO) ModelA payment mechanism in which a transaction is split into two parts: the first part delivers the required number of coins to the receiver, while the second part sends the unspent balance to a different address in the sender's wallet. The total quantity of coins in the wallet is determined by adding all of the wallet's unspent balances.
50Account/Balance Model A payment system in which a transaction entails two simultaneous actions: the owner's wallet balance is lowered by the exact quantity of coins sent out, and the recipient's wallet balance is boosted by coins received; there is no list of unspent balances, only an overall balance. In Ethereum, this paradigm is employed, but in Bitcoin, the UTXO model is used.
51ForkWhen the blockchain's algorithm is modified, a split occurs if different computers (miners) disagree about accepting a new algorithm, one group updates to the new algorithm. In contrast, the other group uses the old, resulting in two independent blockchains with the same origin.
52Hard ForkThe blockchain is updated regularly. Computers running an older version of the blockchain are ejected from the new blockchain.
53Soft ForkA tweak to the protocol that compels computers to update their software regularly. Those who do not upgrade will stay on the blockchain, but they will not submit new blocks.
54Market CapitalizationMultiplying the number of coins in circulation by the current market price of a single coin yield the entire worth of a cryptocurrency. This figure could be in the hundreds of billions of dollars or trillions of dollars.
55The FlippeningThe date when Ethereum is projected to surpass Bitcoin in terms of market valuation.
56Exchange A website or app, like Binance, that lets you open an account and buy cryptocurrencies with bitcoins, altcoins, or fiat currency such as dollars or Euros. Funds are transferred to your account using standard means such as PayPal or wire transfer.
57ArbitragePurchasing cryptocurrencies on one exchange and then selling them on another at a higher price.
58StablecoinA cryptocurrency whose value is linked to the value of a fiat currency, a commodity such as gold, or whose supply is regulated by an algorithm, guaranteeing the currency's value remains steady. Tether is the most well-known stablecoin, with a value of about one US dollar.
59MemecoinA cryptocurrency that was created as a prank. Memecoins have no real-world utility and are only valuable because many people think they're hilarious and buy them for that reason. Dogecoin is the most well-known.
60Dollar Cost Averaging (DCA)Buying a certain quantity of cryptocurrency on a weekly, monthly, or annual basis regardless of price variations. This takes the emotion out of the investment process while maintaining consistency and reaping the benefits of price drops.
61Casascius CoinReal metal bitcoins made by Bitcoin user Casascius (Mike Caldwell), each with a piece of paper containing the private key for a specified amount of bitcoins. A total of 27,673 Casascius coins, worth a total of 59,383.9 BTC, were struck.
62Coin MixerA program that makes bitcoin transactions untraceable and anonymous. This is accomplished by taking a single transaction, combining it with others, and then returning it to the owner at a different address and in different amounts.
63Initial Coin Offering (ICO) People are given a new cryptocurrency in exchange for fiat money, bitcoins, or altcoins. Participants in the ICO hope that the new cryptocurrency they purchased will gain popularity and increase in value.
64Anti-Money Laundering (AML)Anti-money laundering policies and regulations are in place.
65Know your Customer (KYC)The steps are taken to validate a crypto user's identity and link it to their wallet.
66Double Spend An attempt to transmit the identical bitcoin payment to two distinct wallets at the same time.
67EscrowA blockchain third party, such as BitPay, holds cryptocurrency until the vendor gets payment before releasing it to the buyer.
68HODLThis is a common misspelling of "hold," It refers to holding on to your crypto assets until the market recovers.
69FOMO (Fear of Missing Out) Selling other assets to invest in a cryptocurrency with a rising value.
70FUD (Fear, Uncertainty, and Doubt)FUD is common among those who are not involved in the crypto field.
71Rekt Borrowed forms were destroyed, resulting in significant losses.
72Bull MarketA period of time when the price of a cryptocurrency has been rising steadily.
73MooningDue to a long bull market run, the price of a cryptocurrency is skyrocketing—going to the moon.
74Pump and DumpBuying a cryptocurrency in big quantities to inflate its price and encourage others to invest, then selling it all when the price rises and a profit can be earned.
75Shill Someone who promotes an altcoin with the hopes of profiting from its rise in value.
76Bear MarketA period when the price of a cryptocurrency falls for an extended period.
77BagholderAn investor who owns a coin that is worth much less than the price they paid for it.

What Does the Future Hold for Cryptocurrency?

The Matrix and Terminator films depict what might happen to societies when they achieve incredible technical power, centralise it, and lose it to an adversary. Because they run on decentralised computer networks, cryptocurrencies are meant to prevent a Matrix or Skynet scenario.

While cryptocurrencies can bring decentralised financial services to everyone on the planet, they still have a long way to go in terms of development and integration. During that time, fiat currencies and the centralised networks on which they are based will continue to have low volatility and a near-monopoly on global financial transactions.
