Can Cross-Chain Communication Protocols Reduce Reliance on Single-Source Oracles for Asset Pricing?
Yes, cross-chain communication protocols can significantly reduce reliance on single-source oracles. By enabling a smart contract on one blockchain to natively read the state of another, it can directly access and compare asset prices from decentralized exchanges (DEXs) across multiple chains.
This creates a robust, decentralized price feed sourced from diverse liquidity pools. Protocols like Chainlink's Cross-Chain Interoperability Protocol (CCIP) or LayerZero allow for the transmission of messages and data, not just tokens, which can be used to create more resilient, multi-chain price oracles without relying on a single off-chain provider.
