ChainCatcher news, Web3 infrastructure company ChainSafe has announced the launch of a new cross-chain security solution, the Zipline Casper prototype.It is reported that Zipline Casper is an Optimistic-based, trust-minimized, cross-chain block header oracle. It allows anyone to fetch block headers from chains using the Casper finality protocol (such as Ethereum/Gnosis) and submit them on another EVM chain, while ensuring that headers from the original chain that are not finalized will ultimately be rejected on the target chain.ChainSafe plans to have a simplified version of Zipline ready by the end of 2023, and also intends for it to be a core component of the upcoming Sygma cross-chain product.
