Sergey Nazarov (Blockchain / Oracle Networks) at Chainlink — San Francisco, United States

Sergey Nazarov co-founded Chainlink, the world's leading decentralized oracle network that connects blockchain smart contracts with real-world data, APIs, and payment systems. Without oracles like Chainlink, DeFi protocols, prediction markets, and cross-chain bridges would be impossible. Nazarov's vision of a "hybrid smart contract" model combining on-chain and off-chain computation has proven foundational to the DeFi ecosystem's growth to hundreds of billions of dollars in locked value.
