$BOB
BOB Coin, part of the "Build on Bitcoin" (BOB) project, is an initiative focused on integrating DeFi with Bitcoin, using a Layer-2 solution. Recently, it launched the Kailua update, incorporating zero-knowledge fraud proofs (ZK) to enhance decentralization and efficiency in dispute resolution. It has raised $9.5M, totaling $21M, with backing from investors such as Castle Island and RockawayX. BOB aims to be the first hybrid ZK rollup, combining validity and fraud proofs for greater security and scalability. Its community is growing rapidly, with +42% of holders and presence in +35 countries.
