Sergey Nazarov

Sergey Nazarov is a previous Proof of Talk speaker, a co-founder of Chainlink and CEO of Chainlink Labs. His professional work concerns the infrastructure that allows smart contracts to use information and services beyond the blockchain on which they run. Chainlink supplies tools for external data, offchain computation and communication between blockchain networks, connecting application developers with resources that would otherwise sit outside a smart contract’s reach.

Chainlink and Chainlink Labs describe related parts of that work. Chainlink is the technology platform and network, while Chainlink Labs is the organization Nazarov leads. Independent reporting has described the company’s expansion from oracle services into tools for tokenization, connectivity between chains and enterprise data infrastructure. These areas involve more than issuing a digital representation of an asset: applications also need access to prices, information about underlying assets and a way to communicate across different systems.

Nazarov’s public speaking has addressed those connections between decentralized applications and established capital markets. Chainlink’s dated presentation archive includes his September 2025 Sibos keynote on the future of digital assets in capital markets, an April 2024 presentation on connecting Web3 to capital markets, and a November 2025 discussion on payments and interoperability at the Federal Reserve’s fintech conference. These appearances document his professional engagement with payments, digital assets and the systems connecting decentralized applications with established financial markets.

His role places him at the meeting point of blockchain application development and financial infrastructure. For readers following tokenization, his work provides context for the services surrounding an asset after it is represented onchain: the information that informs its contracts, the external systems with which it interacts and the connections needed when participants use different networks.
