Merkle Proof Verification
Merkle Proof Verification is the process by which a user or auditor checks that a specific piece of data exists within a Merkle Tree without needing the entire dataset. To verify, the user is provided with the path of hashes from their leaf node up to the root.
By re-calculating the hashes along this path using their own data, they can see if the final result matches the publicly known root hash. This is an efficient and lightweight process that allows for individual verification of solvency.
It is widely used in cryptocurrency wallets and exchanges to provide users with assurance that their assets are accounted for in the firm's total reserves. This democratization of verification is a key feature of blockchain-based financial systems.
It shifts the burden of proof from the institution to the math itself.
