Chainlink Upgrades Crypto Bridge Security with CCIP 2.0

Chainlink has rolled out a major fix aimed at preventing cross-chain attacks after a $292 million hack in April. The Chainlink CCIP upgrade, officially named CCIP 2.0, gives companies more control over how their cross-chain transfers get verified.

The upgrade allows companies to add optional security verifiers on top of Chainlink's default 16-node operator network, run either in-house or through outside providers such as Infosys and Nethermind.

This change is in response to a $292 million hack that occurred at Kelp DAO in April, which relied on a single verifier. The new upgrade also retires the Risk Management Network, a separate set of nodes that independently double-checked transactions.
