Definition ∞ Verifiable evidence or data directly recorded and secured on a blockchain ledger. This cryptographic proof ensures transparency, immutability, and public auditability of transactions or states. It eliminates the need for trusted third parties to validate information.
Context ∞ The reliance on verifiable data directly recorded on a blockchain is fundamental to the integrity and trustlessness of decentralized systems. Discussions often involve the efficiency of generating and storing such proofs, especially for complex computations or large datasets. Advancements in zero-knowledge proofs and other scaling solutions aim to enhance the practical application of on-chain verification for broader use cases.
