Babylon is a project that designs Bitcoin security sharing protocols with a vision of building a Bitcoin-secured decentralized world. Its latest development is the world’s first trustless and self-custodial Bitcoin staking protocol, which enables Bitcoin holders to stake their BTC on Proof-of-Stake (PoS) systems such as PoS chains, L2s, Data Availability (DA) layers, etc, enabling them to earn yield without the need for third-party custody, bridge solutions, or wrapping services. Babylon's approach combines the high security and wide adoption of Bitcoin with the efficiency and scalability of PoS systems, increasing Bitcoin's utility. Babylon was founded in 2022 by Stanford Professor David Tse and Dr. Fisher Yu. Professor Tse is a member of the U.S. Academy of Engineering and is renowned as the inventor of the legendary proportional-fair scheduling algorithm for wireless communications. Babylon is led by a team of consensus protocol researchers and experienced layer 1 engineers from around the world.

BitSmiley is a Bitcoin-native DeFi project, leading innovation in the BTC DeFi ecosystem. As the first stablecoin project within this space, bitSmiley introduces the Fintegra framework, which includes a decentralized overcollateralized stablecoin protocol, a native trustless lending protocol, and an on-chain derivatives protocol. The initial offering, bitUSD, is an overcollateralized stablecoin backed by native Bitcoin, designed to ensure stability and security. Users can mint bitUSD across multiple chains without bridging or wrapping, maximizing Bitcoin’s derivatives utility and liquidity. By overcollateralizing BTC, users participate in BTC DeFi protocols, with each bitUSD backed by robust liquidation and repayment systems. bitSmiley expands BTC liquidity and provides a secure, efficient pathway for a wide range of BTC's utilities in the DeFi landscape.
