ZeroSync Deployed a System Based on zk-Proofs for Bitcoin Network
Blockchain developer ZeroSync has achieved a significant milestone by implementing the first client system based on Stark proofs for the Bitcoin header chain.
This system, built using Starkware‘s Cairo programming language, is a noteworthy development that allows Bitcoin users to validate the state of the network without the need to download the entire blockchain or rely on third-party intermediaries.
Stark proofs are a type of Zero-Knowledge (ZK) proof developed by StarkWare, offering enhanced privacy and scalability to blockchain networks. ZK proofs enable parties to verify the truth of a statement without revealing additional information, which can help address Bitcoin’s challenges related to transaction speeds and network congestion.
ZeroSync’s verifier for Bitcoin is especially significant for light clients, as it allows them almost instantaneously to verify the inclusion of transactions on the Bitcoin network. Instead of downloading all block headers, these light clients store only a header chain proof.
This innovative approach significantly lowers the entry barriers for users to participate fully in the Bitcoin network. ZeroSync is planning to leverage Stark Proofs to bring mass scalability to Bitcoin in the long term, with a Layer 2 protocol that promises remarkable privacy and scalability properties. This could potentially enable Bitcoin to process over 100 token transactions per second, significantly enhancing its scalability.
ZeroSync’s current release focuses on a verifier for Bitcoin’s header chain, which is a crucial step in the direction of providing full blockchain verification to nodes without the need to download and process the entire blockchain data. The ultimate goal is to deploy a zero-knowledge proof verifier on Bitcoin’s mainnet, which could have far-reaching implications for the network’s scalability and usability.
