Off-Chain Relay

Offchain

An off-chain relay represents a mechanism facilitating communication and state updates between a blockchain and external systems or other blockchains without directly recording every interaction on the primary chain. This approach enhances scalability and reduces transaction costs by processing data and executing logic outside the main blockchain consensus layer. Consequently, relay networks often involve specialized nodes responsible for verifying and relaying information, acting as intermediaries between on-chain smart contracts and off-chain computations or data sources. The design prioritizes efficiency and flexibility, enabling complex interactions and integrations that would be impractical or prohibitively expensive to implement solely on-chain.
