An old miner, after many years of mining, found that his Bitcoin was piled up like a mountain, but he could only leave it idle.

He tried to explore new ways and discovered @build_on_bob, putting Bitcoin into the lending pool and unexpectedly earning his first profit. This made him start to pay attention to the changes in the Bitcoin ecosystem.

BOB, as the entry point for Bitcoin DeFi, is reshaping the entire system. It uses BitVM bridging technology to allow native Bitcoin to directly enter smart contracts without relying on third-party custody. This uniqueness lies in its avoidance of the trust risks associated with traditional bridges, making capital flow more direct.

After integrating Babylon and Euler, BOB created a multi-chain yield product. Users can earn interest across chains using Bitcoin while maintaining the core security of Bitcoin. This has fostered the growth of the developer community, which can build applications using Ethereum tools but settle on Bitcoin, forming a hybrid ecosystem.

The mainnet is about to go live, and BOB's focus is on scalability. It supports the rapid deployment of DeFi applications, lowering the entry barrier and allowing more people to benefit from Bitcoin. This is not just a technical upgrade, but a push for Bitcoin's evolution from a single asset to a comprehensive platform.
