Celer Network announced on social media that the BRC-20 cross-chain bridge will be released in two phases. The first phase will release a cross-chain bridge based on SGN, and according to its xAsset locking and minting model, the SGN cross-chain bridge will ensure security through PoS and Optimistic dual-mode consensus. The second phase will integrate with the intelligent ZK co-processing unit Brevis to achieve a trustless BRC-20 zkBridge, using ZKP to enhance security.
