FTSE Russell Takes First Step Toward On-Chain Benchmark Data With Chainlink

The post FTSE Russell Takes First Step Toward On-Chain Benchmark Data With Chainlink appeared on BitcoinEthereumNews.com.

In brief FTSE Russell will publish its global equity, FX, and digital asset benchmarks directly on blockchain networks. The data will be accessible to over 2,000 applications across more than 50 public and private blockchains. Observers say the move could transform traditional reference indices into programmable and verifiable financial primitives. FTSE Russell, a global index and data provider, is publishing its market index data on blockchain networks for the first time through Chainlink, a decentralized oracle service widely used across financial and blockchain applications. The index’s equity, FX, and digital asset benchmarks will be published on multiple blockchains via DataLink, a Chainlink service that connects traditional financial data to over 2,000 applications across more than 50 networks. Bringing index data on-chain through Chainlink’s infrastructure would help “securely distribute underlying data” from FTSE Russell’s benchmarks and give trusted, quality data “that powers traditional finance” to institutions and developers, Fiona Bassett, CEO at FTSE Russell, said in a statement on Monday.  The integration makes FTSE Russell’s global indices continuously available on-chain, allowing developers to securely reference and use them across multiple chains and networks. Publishing data on-chain “turns traditional reference indices into programmable, verifiable financial primitives,” Ram Kumar, core contributor at blockchain infrastructure firm OpenLedger, told Decrypt. It’s a collaboration that “bridges TradFi standards with DeFi infrastructure,” making “canonical benchmarks natively available,” while helping “bring institutional legitimacy” to on-chain finance, Kumar explained. How do blockchain oracles work with indices? Oracles act as data bridges between blockchains and the outside world, feeding information that smart contracts cannot access on their own. Each oracle network collects data from trusted sources, verifies it through multiple independent nodes, and delivers a cryptographically signed record on-chain. The process ensures accuracy and transparency without relying on a single intermediary. It also lets institutions and users rely on…
