According to news on October 9, Xiaohui Liu, head of the MVC technology department and founder of sCrypt, announced on Twitter that the research on the Bitcoin side chain MVC (MicrovisionChain) has made significant progress in the third quarter of 2024, and will implement the following in the next six months. Three aspects: 1. Fully enable the OP_CAT opcode: MVC, as a Bitcoin side chain, will use the OP_CAT opcode to support Layer-1 smart contracts, allowing developers to build Turing-complete decentralized applications (DApps) under the UTXO model ). 2. SegWit integration: The introduction of SegWit will improve transaction processing efficiency, reduce transaction fees, and optimize the execution of smart contracts to ensure higher transaction throughput and security. 3. Merged mining research: MVC will further strengthen the decentralized security model by merging mining with Bitcoin and leveraging the security and computing power of the Bitcoin network, while attracting more miners to participate.
