EOS is a blockchain platform launched in 2018 by Block.one and its then-CTO Dan Larimer, providing infrastructure — accounts, authentication, databases, communication, and application scheduling — for decentralized applications. Block.one raised roughly $4 billion in its 2017–2018 token sale to fund the platform, one of the largest in blockchain history.

Larimer left Block.one at the end of 2020, and EOS lost roughly 30 percent of its value within 18 hours of the announcement, exposing how closely the ecosystem's fortunes were tied to a single founder. Block.one subsequently grew estranged from the EOS chain it had built, and the EOS Network Foundation emerged as the ecosystem's de facto steward, funding continued development — including renewed contributions from Larimer, who returned to EOS-adjacent work in 2022. 📝Buttrfly, an influencer-marketing marketplace introduced to me by investor 📝Tony Anthony, is one of the decentralized applications built on EOS's architecture.

Key Features

• Delegated Proof of Stake — a consensus model where token holders elect block producers, trading some decentralization for higher throughput.
• Account-based identity — human-readable account names rather than raw wallet addresses, with resource allocation tied to token stake.
• Free-at-use transactions — apps stake EOS for network resources rather than users paying gas per transaction.
• Inter-blockchain communication — built-in tooling for applications to interact across chains.
