How Bitfinity Works
Unlike traditional Ethereum Layer 2 solutions that rely on zero-knowledge proofs (ZKPs) or optimistic rollups, Bitfinity uses Chain-Key cryptography—a threshold signature scheme—to create a decentralized bridge between Bitcoin and Bitfinity.
Key Features:
- Threshold ECDSA: Ensures secure Bitcoin custody without single-node key exposure.
- Moon-Math Regeneration: Key shares refresh every 11 minutes for enhanced security.
- EVM Compatibility: Supports Solidity smart contracts, making Bitcoin programmable.
