 # Chainlink Documentation
 
-> Chainlink is the backbone of blockchain. It is the standard for onchain finance, verifiable data, and cross-chain interoperability. It unifies liquidity across global markets and has enabled over $20 trillion in transaction value across the blockchain economy. Major financial institutions like Swift, Fidelity International, and ANZ Bank, as well as top DeFi protocols such as Aave, GMX, and Lido, utilize Chainlink to power next-generation applications in banking, asset management, and other sectors.
+> Chainlink is the industry-standard oracle platform bringing the capital markets onchain and powering the majority of decentralized finance (DeFi). The Chainlink stack provides the essential data, interoperability, compliance, and privacy standards needed to power advanced blockchain use cases for institutional tokenized assets, lending, payments, stablecoins, and more. Since inventing decentralized oracle networks, Chainlink has enabled tens of trillions in transaction value and now secures the vast majority of DeFi.
+Many of the world’s largest financial services institutions have also adopted Chainlink’s standards and infrastructure, including Swift, Euroclear, Mastercard, Fidelity International, UBS, S&P Dow Jones Indices, FTSE Russell, WisdomTree, ANZ, and top protocols such as Aave, Lido, GMX and many others. Chainlink leverages a novel fee model where offchain and onchain revenue from enterprise adoption is converted to LINK tokens and stored in a strategic [Chainlink Reserve](https://blog.chain.link/chainlink-reserve-strategic-link-reserve/).

 This document offers simple, clean, and comprehensive resources for developers to learn, experiment, and build with Chainlink.
