Study Notes | Cross-Chain Bridges
① Cross-chain protocols need a mechanism to prove that an operation actually took place on the source chain. Common methods include multisig or validator committees, light-client verification, and zero-knowledge proofs.
② When wrapped assets are transferred back to the original chain, the process works in reverse: the wrapped assets on the destination chain are first burned, then the assets locked on the source chain are unlocked.
③ Before making a cross-chain transfer, check the bridge’s official website. Fake cross-chain websites are a common scam.
