BitVM Bridge is a cross-chain bridge developed by @BitlayerLabs for connecting Bitcoin with the decentralized finance ecosystem, built on the BitVM smart contract framework.
Compared to other cross-chain protocols, its advantages mainly manifest in the following aspects:
1. Extremely low trust threshold: Traditional cross-chain bridges rely on multi-signature custody or 'honest majority of nodes', while BitVM Bridge only requires 1 honest participant to ensure asset security, significantly reducing reliance on third parties.
2. Dual proof technology for protection: Combining fraud proof and zero-knowledge proof, it prevents malfeasance while ensuring transparency, offering superior security compared to a single mechanism.
3. Strong adaptability to multiple ecosystems: It not only supports EVM chains (such as Base, Arbitrum) but also plans to expand to non-EVM ecosystems like Solana, enabling flexible connections between different blockchain networks.
4. Specifically addresses Bitcoin DeFi pain points: It can safely convert BTC into programmable YBTC, allowing Bitcoin to transcend the limitations of 'store of value' and directly participate in lending, mining, and other DeFi activities, which is challenging for most cross-chain protocols to achieve for Bitcoin.
