Block.one

Block.one is a blockchain technology company and investment firm incorporated in the Cayman Islands. It is best known as the originator of EOSIO, an open-source blockchain software protocol designed for building and scaling decentralised applications, using a delegated proof-of-stake consensus mechanism.

The company was founded in 2016 by Brendan Blumer and Dan Larimer. In 2017 to 2018, Block.one conducted an EOS token sale that raised over $4 billion, at the time the largest initial coin offering on record. Block.one has since deployed capital across more than 140 businesses, including Bullish, a regulated digital asset exchange, and has supported projects in blockchain infrastructure, gaming, and financial services.

EOSIO was released as open-source software in June 2018 and has been adopted by developers building decentralised applications across multiple industries. Voice, an NFT marketplace, and Mythical Games, a blockchain gaming platform, are among the ventures that emerged from the Block.one ecosystem.
