## Hash Chain Consistency

Hash Chain Consistency is a property of a Merkle Tree where each parent node is a hash of its children, creating a secure chain of dependencies that cannot be broken. If any data at the bottom of the tree is changed, the hash of that node changes, which ripples up the entire tree, changing the final Merkle Root.

This makes it impossible to tamper with the data without detection. In an audit, consistency ensures that the reported total liabilities are exactly the sum of all individual user balances.

It is a fundamental cryptographic assurance that the audit data is complete and accurate. This consistency is what makes the audit verifiable by any third party.

It turns a large dataset into a single, manageable, and tamper-proof proof.
