Babylon

Babylon scales Bitcoin security to the Proof-of-Stake economy via decentralized staking and timestamping protocols.

Babylon transforms Bitcoin into a security layer for the broader blockchain ecosystem. By utilizing the Bitcoin Staking Protocol, it allows BTC holders to earn rewards from PoS networks while maintaining self-custody. The architecture integrates three core components: a staking protocol for trustless lockups, a timestamping service to prevent long-range attacks, and a data availability layer. This setup enables nascent chains to inherit Bitcoin's $1 trillion market cap security without requiring bridges or third-party trust.
