zkSync Era announced on Twitter the launch of a new proof system upgrade, Boojum, which will assist the network in transitioning to a proof system supported by STARK to further achieve decentralization. The team intentionally designed zkSync Era to perform cryptographic upgrades without regenesis, which means that the Boojum upgrade will not cause any user interruptions.
zkSync Era said that the long-term goal of the project is to achieve user-driven, decentralized proof generation. The Boojum upgrade represents a breakthrough in this direction: the prover runs on consumer-grade GPUs and only requires 16 GB of GPU RAM. In addition, Boojum will also provide performance supplements to the zkSync Era sequencer.
Boojum is now live on the mainnet, generating and verifying “shadow proofs” with real production data so that the team can test the system before fully migrating.
