Sergey Nazarov has worked in the blockchain industry since 2010, giving him one of the longest-running tenures of any technologist in the industry, which began only a year earlier in 2009 with Bitcoin’s creation. Sergey initially built some of the first smart contracts before blockchains like Ethereum were even a concept and went on to invent Decentralized Oracle Networks in the Chainlink whitepaper, which is the core technology powering Chainlink and underpinning the majority of data transfer onto all chains. After Chainlink became the leading source of all data transfer into various blockchains, it was successfully expanded to become the most secure form of cross-chain connectivity across blockchains for both data and value transfer. Chainlink has so far enabled over $22 trillion in transaction value.
