BOS aims to transform Bitcoin into a programmable base layer for digital economies. The company made headlines after verifying the first zero-knowledge (ZK) proof on Bitcoin mainnet, a milestone enabling programmability without altering the original protocol.
The project is part of the Bitcoin decentralized finance (BTCFi) sector, which has emerged in the last couple of years to enable the deep wells of liquidity held in BTC to finance utility elsewhere in the digital asset ecosystem.
BOS plans to use the funds to scale its developer and institutional infrastructure, including Grail Pro, a BTC yield protocol now in pilot with custodians. The project also supports trustless bridging across other blockchain networks such as Ethereum and Cardano.
Greenfield Capital’s Jascha Samadi called the breakthrough “a fundamental shift in blockchain infrastructure,” arguing BOS is turning Bitcoin into the secure foundation for the broader digital asset economy.
