Altcoin
Any cryptocurrency other than bitcoin.
Bitcoin
A peer-to-peer digital currency created in 2009 that offers the promise of lower transaction fees than traditional online payment mechanisms. Unlike government-issued currencies, bitcoin is run and ‘regulated’ by its own users using a technological infrastructure called a “blockchain.” Bitcoin was created by someone whose identity has not yet been verified who goes by the name of Satoshi Nakamoto.
Blockchain
A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via an algorithm. This public ledger records all transactions that have ever been executed on that blockchain. Blockchains are constantly growing, as completed ‘blocks,’ or transactions, are added in a linear, chronological order. Every computer connected to the Bitcoin network gets a copy of the blockchain which, in theory, makes the whole system more secure as more computers, or “nodes”, become part of the blockchain.
Cryptocurrency
Cryptocurrency, or crypto, is a digital currency designed to work as a medium of exchange or store of value through a blockchain network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it.
Decentralized Finance (DeFi)
Financial services that operate with blockchain technology to facilitate transactions directly between participants. DeFi uses blockchain and peer-to-peer networks to facilitate financial services like lending, staking, and trading. DeFi services operate without a central authority.
Ethereum
A decentralized blockchain platform that enables programable financial transactions through smart contracts. It supports a wide range of financial applications, including decentralized finance (DeFi) services like lending, borrowing and trading without intermediaries. Ethereum’s native cryptocurrency, Ether (ETH), is used to pay for transaction fees and services on the network, and the platform operates on a Proof of Stake (PoS) system to validate and secure transactions.
Exchange
The marketplace where securities, commodities, derivatives and other financial tools such as ETFs are traded. Exchanges, such as stock exchanges, allow for fair and orderly trading and efficient circulation of securities prices. Exchanges give firms looking to market publicly listed securities the platform to do this.
Exchange Traded Fund (ETF)
An ETF is an open-ended fund that provides exposure to underlying investment, usually an index. Like an individual stock, an ETF trades on an exchange throughout the day. Unlike mutual funds, ETFs can be sold short, purchased on margin and often have options chains attached to them.
Futures
Financial contracts that obligate buyers and sellers to buy or sell an asset — often physical commodities or financial instruments — at a predetermined future date and price. Futures contracts also stipulate the quality and quantity of the underlying asset and are standardized to facilitate trading on a futures exchange. Some futures call for physical delivery; others are settled in cash.
Futures Exchange
A central marketplace where futures contracts, options or other derivatives are traded.
Non-fungible Token (NFT)
A unique digital identifier that is recorded on a blockchain and used to certify ownership and authenticity. It cannot be copied, substituted, or subdivided. NFT ownership is recorded in the blockchain and can be transferred by the owner, allowing NFTs to be sold and traded.
Proof of Work (PoW)
A consensus mechanism used by many blockchains, including bitcoin, where miners compete to solve cryptographic puzzles to validate transactions and create new blocks, earning bitcoin in the process. Bitcoin follows a PoW structure to validate transactions.
Proof of Stake (PoS)
An mechanism where validators on a blockchain are chosen to create new blocks based on the number of coins they hold and are willing to "stake" as collateral.
Smart Contract
A self-executing contract with the terms of the agreement directly written into code. These digital contracts execute automatically once certain terms and conditions are met.
Stablecoin
A type of cryptocurrency that is pegged to a stable asset, such as a fiat currency like the US Dollar or a commodity like gold.
Tokenization
The process of converting rights to an asset into an immutable digital token on a blockchain. Tokenization often involves issuing digital tokens to represent ownership of an asset. Tokens are usually immutable and tradable.
