On November 13th, Bitlayer, a Bitcoin-based native two-layer project based on Bitcoin finality, announced that it has contributed the first viable Groth16 verification script splitting implementation to the BitVM open-source project. The 1GB Groth16 verification script gets 975 chunks after splitting, and all chunks can meet the Bitcoin runtime limit. This implementation complements the key components in the BitVM implementation, making it possible for the BitVM protocol to run on the Bitcoin mainnet. In addition, Bitlayer revealed that it plans to launch the BitVM bridge testnet by the end of 2024.
