Odaily Planet Daily News BOB (Buildon Bitcoin) announced a partnership with zero-knowledge proof infrastructure RISC Zero. By integrating Kailua, a hybrid architecture framework launched by RISC Zero, it will become the industry's first Rollup project to use zero-knowledge proof as fraud proof. It will significantly save time and costs of existing settings, and can shorten the withdrawal time from the usual 7 days to 1 hour. This is a key step for BOB to achieve Rollup Phase 1 and Phase 2 on L2beat.

BOB is the first chain to use zero-knowledge proof (ZK). Compared with the Optimistic Rollup with slow withdrawal speed and expensive anti-fraud mechanism and the ZK Rollup with high operating cost, this new method combines the advantages of both.

Alexei Zamyatin, co-founder of BOB and founding member of the BitVM Alliance, said: “With the launch of a fully functional proof system, BOBL2 will have full Ethereum security. This means that BOB will remain on the L2 layer of Phase 0, while most other L2 layers will move to other categories on L2Beat. Phase 1 Rollup only depends on the launch of the Security Committee, which will be announced in the near future. Phase 2 Rollup only requires opening the proposal process to anyone.”
