Ledger Anchoring

Definition ∞ Ledger anchoring is a process where data from one distributed ledger or system is cryptographically recorded onto another, typically more secure or established, ledger. This mechanism provides enhanced data integrity and immutability by leveraging the security properties of the destination ledger. It effectively creates a verifiable link, ensuring that the original data cannot be tampered with without detection. This technique reinforces the trustworthiness of information.
Context ∞ Ledger anchoring is gaining prominence in discussions about interoperability and data security across various blockchain networks and traditional databases. Its utility in providing tamper-proof audit trails for off-chain data or less secure ledgers is a significant development. The focus in news and research often centers on the efficiency and security implications of linking disparate data systems.
