Problem
Bitcoin's scripting language has limited functionality, hindering its ability to verify complex computations and interact with other blockchain networks. This restricts the development of decentralized finance (DeFi) and other advanced applications directly on the Bitcoin blockchain.
Solution
Fiamma is developing a zero-knowledge proof (ZKP) verification layer for Bitcoin, leveraging BitVM2 technology to enable Bitcoin to verify a broader range of applications. This allows for trustless bridging and enhanced interoperability with other chains, expanding Bitcoin's utility in decentralized finance and other internet applications. Fiamma's implementation of BitVM2 introduces optimistic on-chain ZKP verification for Bitcoin, paving the way for more robust Bitcoin-native applications. The core innovation lies in creating a highly compact ZKP verifier on Bitcoin, optimizing the verification process.
Target Audience
The primary target audience includes Bitcoin holders seeking to earn yields through ZKP verification, as well as developers building DeFi applications and seeking interoperability solutions for the Bitcoin network.
