Introduction
A blockchain bridge enables digital assets and data to move between different blockchains. It creates interoperability across otherwise siloed ecosystems.
SupraNova currently uses a trustless bridging model called HyperNova. It validates cross-chain messages using validator signatures and membership proofs, ensuring that only verified data is accepted. This mechanism is cryptographically secure and does not rely on centralized intermediaries. Additionally SupraNova applies cryptographic proofs and ancestry verification to further enhance message integrity, thus removing the need for a multisig committee or centralized relay.
SupraNova supports two bridging protocols:
- HyperNova is a trustless bridge that uses the external verifiability of source chain consensus layer. For example, it uses Sync committee signatures and ancestry proofs in Ethereum. It’s used for high-security, cryptographically secure bridging.
- HyperLoop is a fast, multi-signature bridge for Layer2s and the chains that do not support external verifiability of its consensus. It prioritizes low latency and cost, and provides game-theoretic security.
