ZetaChain, an interoperability-focused Layer-1 network, experienced a six-hour outage due to a consensus failure linked to a recent update. The mainnet has resumed block production, but the testnet is now halted due to the same issue. Cross-chain transactions are delayed, and the network plans to share a post-mortem. ZetaChain aims to integrate different networks like Bitcoin, Ethereum, and Polygon, and raised $27 million in funding last year.
