Enhancing both interoperability and scalability, zkBridge employs state-of-the-art zero-knowledge proof systems. By utilizing zkSNARKs, it allows a prover to effectively assure the receiving blockchain that a specific state transition has occurred on the originating blockchain. The zkBridge framework encompasses a block header relay network and an updater contract, which work in tandem to maintain system integrity. This relay network fetches block headers from the sender blockchain, creates validity proofs for these headers, and transmits them along with their proofs to the updater contract established on the receiver blockchain. The updater contract is responsible for upholding a light-client state, automatically incorporating block headers from the sender blockchain once their corresponding proofs are validated, while simultaneously refreshing the current main chain status of the sender. Additionally, the Polyhedra Network supports the development of infrastructure for seamless interoperability among diverse systems, ensuring robust security without imposing additional trust requirements. This innovative approach not only streamlines cross-chain communication but also fortifies the overall ecosystem against potential vulnerabilities.
