PANews reported on March 17th that Sui Developers announced on the X platform that Sui's new virtual machine (VM) has been publicly released and a bug bounty program has been launched, hoping to gain community review before the mainnet launch. The bella-ciao branch is a rewrite of the execution layer, featuring faster speed, packet caching, and next-generation Move functionality. It has already passed internal review and multiple independent audits of osec_io and zellic_io. Bug reports can be submitted through HackenProof, with rewards paid according to mainnet standards, valid until the testnet launch.
