Decentralized oracle network Chainlink has launched its data feeds on Polygon's zero-knowledge scaling solution compatible with the ethereum virtual machine.
In a press release shared with crypto.news, Chainlink said the expansion now allows blockchain developers to build decentralized applications on Polygon's zkEVM in a new way, resilient to API downtime and flash loan attacks.
Polygon Labs director Marc Borion said the integration of Chainlink oracles will unlock the deployment of “several important protocols on Polygon zkEVM early next year,” without revealing details.
“Chainlink oracles unlock a wealth of DeFi applications, providing opportunities for new dApps that truly leverage the unique value propositions of a ZK rollup, including fast finality and strong security.”

Chainlink oracles are decentralized applications that connect blockchains to off-chain data sources. These programs allow smart contracts to access real-world information such as prices, events, and other data not stored on the blockchain.
In November 2023, Chainlink rewarded White hat hackers Zach Obront and Or Cyngiser (Trust) receive a $300,000 reward for discovering a critical bug that could have compromised the integrity of their verifiable random function (VRF), a random number generator that enables smart contracts. access random values without compromising security. .
In 2022, Trust and Obront discovered that an owner of a malicious VRF subscription could manipulate the system to manipulate the random number generation process. By repeatedly blocking and repeating the randomness, white hat hackers learned that they could force users to receive an undesirable result while obtaining the desired value for themselves.
