Definition ∞ Proof-carrying messages are data transmissions that include a cryptographic proof verifying the correctness or validity of the message’s content or its sender’s actions. These proofs allow recipients to confirm the authenticity and integrity of the message without needing to trust the sender or a third party. This mechanism enhances security and efficiency in decentralized communication.
Context ∞ In the realm of cross-chain communication and layer-2 solutions, proof-carrying messages are becoming increasingly relevant for ensuring secure and trustless interactions between disparate blockchain environments. News frequently covers new protocols and advancements that leverage this technology to improve the reliability and safety of inter-blockchain operations.
