@BounceBit is a crypto project (with its native token BB) that aims to bridge CeFi (Centralized Finance) and DeFi (Decentralized Finance) under what they call a CeDeFi model. It has a dual-token Proof of Stake (PoS) setup: users stake both BB (native BounceBit token) and a BTC-pegged or BTC-derived token (often called BBTC or similar).
