Adam Back is a British cryptographer and cypherpunk. He is the CEO of Blockstream, which he co-founded in 2014. He invented Hashcash, which is used in the bitcoin mining process.
Bitcoin is the first decentralized cryptocurrency. Nodes in the peer-to-peer bitcoin network verify transactions through cryptography and record them in a public distributed ledger, called a blockchain, without central oversight. Consensus between nodes is achieved using a computationally intensive process based on proof of work, called mining, that secures the bitcoin blockchain. Mining consumes large quantities of electricity and has been criticized for its environmental impact.
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 until December 2010.
A cryptocurrency, crypto-currency, or crypto is a digital currency designed to work through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it.

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.
NXT is an open source cryptocurrency and payment network launched in 2013 by anonymous software developer BCNext. It uses proof-of-stake to reach consensus for transactions—as such, there is a static money supply. Unlike Bitcoin, there is no mining. NXT was specifically conceived as a flexible platform around build applications and financial services, and serves as basis for ARDR (Ardor), a blockchain-as-a-service multichain platform developed by Jelurida, and IoTeX (cryptocurrency) the current steward of NXT as of 2021. NXT has been covered extensively in the "Call for Evidence" report by ESMA.

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 2008 by Satoshi Nakamoto, in which Nakamoto referred to Bitcoin as a peer-to-peer electronic cash system.
Monero is a cryptocurrency which uses a blockchain with privacy-enhancing technologies to obfuscate transactions to achieve anonymity and fungibility. Observers cannot decipher addresses trading Monero, transaction amounts, address balances, or transaction histories.
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.
Craig Steven Wright is an Australian computer scientist and businessman. He has publicly claimed to be the main part of the team that created bitcoin, and the identity behind the pseudonym Satoshi Nakamoto. These claims are generally regarded as false by the media and the cryptocurrency community. In March 2024, Mr Justice James Mellor in the British High Court ruled that Wright is not Satoshi Nakamoto. In July 2024, a British High Court judge referred Craig Wright to UK prosecutors for alleged perjury related to his claims of being Satoshi Nakamoto. As of 2019, Wright lived in the United Kingdom.
