Meaning
Cryptographic proof that ties a large dataset to a single hash value stored on a secure ledger. Use of a Merkle tree anchor allows anyone to verify that a specific piece of data was part of a larger set at a certain time. This technique is used to prove the integrity of digital records without showing the whole database. it is a staple of blockchain technology.
Data Integrity
Integrity of the information is guaranteed by the mathematical properties of the hash. A Merkle tree anchor provides a way to detect any change in the underlying data. If a single bit is changed, the anchor hash will no longer match.
Verification Proof
Proof of existence for a document is provided by the anchor and its associated path. Within a Merkle tree anchor, the record of the path allows a user to verify their data against the public hash. This process is fast and efficient.
Cryptographic Consistency
Consistency of the record over time is maintained by the immutable nature of the anchor. By using a Merkle tree anchor, a company can prove that its records have not been altered since they were first recorded. This is a powerful tool for audits.
The anchor is permanent.
