Chainlink, under the leadership of co-founder Sergey Nazarov, is at the forefront of transitioning global finance onto blockchain technology. The network's oracles have facilitated over $27 trillion in on-chain data transactions and currently support 70% of the decentralized finance (DeFi) sector. In 2025, Chainlink formed strategic partnerships with Swift, DTCC, UBS, and the U.S. government to integrate real-world assets onto blockchains. Nazarov anticipates that 2026 will be pivotal as traditional finance and DeFi converge.
