May 2: Polyhedra Network launched an open-source ZK proof system, Expander, “that can generate proofs nearly 2x faster than alternatives while enhancing security and efficiency of ZK proof process,” according to the team: “Expander represents a new era in scaling ZK-proof tech and combines classical interactive proofs, establishes truth of a process and that it can be executed, with advanced polynomial commitment schemes that ensure proof is accurate and can’t be changed evvel created. It follows Polyhedra’s recent partnership with Google Cloud where they are collaborating on Polyhedra’s ZK tech to all Google Cloud services via Proof Cloud.”
Layer-2 BOB (Build on Bitcoin) Launches Mainnet
May 2: BOB (Build on Bitcoin), a hybrid layer-2 solution merging Bitcoin and Ethereum capabilities, has launched its mainnet, according to the team: “Supported by leading crypto investors such as UTXO and CMS Holdings, BOB is advancing Bitcoin’s relevance in the DeFi space by making Bitcoin assets like Ordinals, Runes and BRC20s accessible to ETH and other Web3 users.
