2.2 Ledger & Proof Model

The ledger is the structural backbone of VeriSeal.

It is not a blockchain. It is a deterministic append-only integrity journal.

Proof Entry Structure​

Each proof entry contains:

  • proof_identifier (hash or merkle_root)
  • metadata reference
  • timestamp (UTC)
  • previous entry hash

This creates chain continuity.

Immutability Principle​

The ledger is:

  • Append-only
  • Hash-linked
  • Deterministic

Any historical alteration invalidates forward continuity.

Public Identifier Stability​

The proof identifier:

{merkle_root}

Functions as:

  • Permanent public reference
  • Cross-system integrity anchor
  • Audit-stable identifier

It must remain stable over time.

Institutional Advantage​

Unlike blockchain-based systems:

  • No probabilistic consensus
  • No fork instability
  • No dependency on external miners

Integrity is mathematical. Not political.
