Babylon is a protocol for staking native bitcoin. You lock BTC in a time-locked script on the Bitcoin blockchain, and that stake helps secure proof-of-stake networks in exchange for rewards. The BTC never leaves the Bitcoin chain or your control, and it isn't wrapped or bridged 2. Babylon Labs builds the protocol. Its companion chain, Babylon Genesis, went live on April 10, 2025 and coordinates staking, slashing and rewards using the BABY token 38. The trade-off: staked BTC is locked for a period and can be partly slashed if the validator you choose misbehaves 2.
