ZeroSync Implements Stark Proofs for Instant Bitcoin Verification
Blockchain developer ZeroSync has achieved a significant milestone by implementing a client system based on Stark proofs for the Bitcoin header chain.
This development, built on Starkware’s Cairo programming language, allows Bitcoin users to validate the network’s state without the need to download the entire blockchain or rely on a third party. The project leverages Starks, a type of Zero-Knowledge (ZK) proof developed by StarkWare, to address Bitcoin’s challenges related to transaction speeds and network congestion.
Zero-Knowledge proofs (ZK proofs) are cryptographic techniques that offer enhanced privacy and scalability by allowing a party to verify the truth of a statement without disclosing additional information. ZeroSync’s implementation of a verifier for the Bitcoin header chain is a significant advancement for light clients, such as wallets. These clients can now verify the inclusion of transactions on the Bitcoin network nearly instantly, while only needing to store a header chain proof instead of downloading the entire block headers. This achievement is expected to lower the entry barriers for individuals and entities looking to participate fully in the Bitcoin network.
Looking ahead, ZeroSync has ambitious plans to further enhance Bitcoin’s scalability using Stark Proofs. The company is working on implementing a Layer 2 protocol with advanced privacy and scalability features, aiming to enable Bitcoin to process more than 100 token transactions per second. This development could play a crucial role in addressing Bitcoin’s scalability requirements and improving its overall efficiency as a decentralized network.
