PANews reported on October 30 that according to CoinDesk, Bitcoin Layer-2 project BOB announced that it has joined the Superchain ecosystem of Ethereum Layer-2 network Optimism, becoming the first Bitcoin native project integrated in this ecosystem. BOB is positioned as a "hybrid Layer-2" network, built on Bitcoin and compatible with Ethereum, aiming to make Bitcoin a decentralized finance (DeFi) center by establishing a bridge with Layer-1 blockchains such as Ethereum. BOB will receive $870,000 in funding from the Optimism Foundation.
