Bitcoin is a protocol which implements a public, permanent, and decentralized ledger. In order to add to the ledger, a user must prove they control an entry in the ledger. The protocol specifies that the entry indicates an amount of a token, bitcoin with a minuscule b. The user can update the ledger, assigning some of their bitcoin to another entry in the ledger. Because the token has characteristics of money, it can be thought of as a digital currency.
Satoshi Nakamoto is the name used by the presumed pseudonymous person or persons who developed bitcoin, authored the bitcoin white paper, and created and deployed bitcoin's original reference implementation. As part of the implementation, Nakamoto also devised the first blockchain database. Nakamoto was active in the development of bitcoin up until December 2010.
A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work as a medium of exchange through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. It is a decentralized system for verifying that the parties to a transaction have the money they claim to have, eliminating the need for traditional intermediaries, such as banks, when funds are being transferred between two entities.
Litecoin is a decentralized peer-to-peer cryptocurrency and open-source software project released under the MIT/X11 license. Inspired by Bitcoin, Litecoin was among the earliest altcoins, starting in October 2011. In technical details, the Litecoin main chain shares a slightly modified Bitcoin codebase. The practical effects of those codebase differences are lower transaction fees, faster transaction confirmations, and faster mining difficulty retargeting. Due to its underlying similarities to Bitcoin, Litecoin has historically been referred to as the "silver to Bitcoin's gold." In 2022, Litecoin added optional privacy features via soft fork through the MWEB upgrade.
Bitcoin is a cryptocurrency, a digital asset that uses cryptography to control its creation and management rather than relying on central authorities. Originally designed as a medium of exchange, Bitcoin is now primarily regarded as a store of value. The history of bitcoin started with its invention and implementation by Satoshi Nakamoto, who integrated many existing ideas from the cryptography community. Over the course of bitcoin's history, it has undergone rapid growth to become a significant store of value both on- and offline. From the mid-2010s, some businesses began accepting bitcoin in addition to traditional currencies.
Nicholas Szabo is a computer scientist, legal scholar, and cryptographer known for his research in digital contracts and digital currency. He graduated from the University of Washington in 1989 with a degree in computer science and received a Juris Doctor degree from George Washington University Law School. He holds an honorary professorship at the Universidad Francisco Marroquín.
Vitaly Dmitrievich Buterin, better known as Vitalik Buterin, is a Russian-Canadian computer programmer, and founder of Ethereum. Buterin became involved with cryptocurrency early in its inception, co-founding Bitcoin Magazine in 2011. In 2014, Buterin deployed the Ethereum blockchain with Dimitry Buterin, Gavin Wood, Charles Hoskinson, Anthony Di Iorio, and Joseph Lubin.
Ethereum is a decentralized blockchain with smart contract functionality. Ether is the native cryptocurrency of the platform. Among cryptocurrencies, ether is second only to bitcoin in market capitalization. It is open-source software.
A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Since each block contains information about the previous block, they effectively form a chain, with each additional block linking to the ones before it. Consequently, blockchain transactions are irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks.
Andreas M. Antonopoulos is a British-Greek Bitcoin advocate, tech entrepreneur, and author. He is a host on the Speaking of Bitcoin podcast and a teaching fellow for the M.Sc. Digital Currencies at the University of Nicosia.
Roger Keith Ver is an early investor in Bitcoin, Bitcoin-related startups and an early promoter of Bitcoin. Ver has sometimes been referred to as "Bitcoin Jesus". He now primarily promotes Bitcoin Cash as Ver sees it as fulfilling the intended and original purpose of the "Bitcoin White Paper", first published in 2009 by Satoshi Nakamoto, in which Nakamoto referred to Bitcoin as a peer-to-peer electronic cash system.
Wei Dai is a computer engineer known for contributions to cryptography and cryptocurrencies. He developed the Crypto++ cryptographic library, created the b-money cryptocurrency system, and co-proposed the VMAC message authentication algorithm. The smallest subunit of Ether, the wei, is named after him.
Consensys is a private blockchain software technology company founded by Joseph Lubin and based in New York City.
Ethereum Classic is a blockchain-based distributed computing platform which offers smart contract (scripting) functionality. It is open source and supports a modified version of Nakamoto consensus via transaction-based state transitions executed on a public Ethereum Virtual Machine (EVM).
Jed McCaleb is an American programmer, entrepreneur, and philanthropist. He is the founder and CEO of aerospace startup Vast and a co-founder and the CTO of Stellar.
