Mustard Seal EAR99
Mustard Seal is the cryptographic commitment layer of the Mustard Chain bilateral micro-ledger. At configurable intervals, Mustard Seal computes a commitment (hash root) of the current chain state and publishes it to a verifiable public layer. This enables third-party audit of chain integrity without exposing the underlying transaction data, party identities, or internal ledger structure. The seal acts as a notarization point — any party (including those outside the bilateral relationship) can verify that the chain state at the time of sealing was authentic and unmodified. Mustard Seal bridges the gap between the privacy of bilateral ledgers and the transparency of public blockchains.
How XO Defense Addresses This
Mustard Seal is Phase 3 of the Mustard Chain protocol (MC-001), extending bilateral integrity to third-party verification. In defense applications, Mustard Seal enables command authority to audit field transactions without requiring access to the raw ledger data — verifying that supply chain records, payment transactions, or command acknowledgments are authentic without exposing operational details. The seal mechanism is designed for constrained environments: the commitment itself is a fixed-length cryptographic hash that can be transmitted via Mustard Envelope over any transport in the XO Defense matrix.
