H33-74 on Solana

How H33-74 anchors to Solana

Each anchor is a Solana transaction that commits to a receipt's cryptographic identity (or to a batched commitment covering many receipts). The anchor lives in Solana's canonical ledger and is independently verifiable via any Solana block explorer.

Anchor mechanism on Solana

H33-74 anchors to Solana via memo-instruction commitments and program-controlled anchor accounts. Receipts can be anchored individually for low-latency notarization or batched for cost efficiency.

Chain parameters

What an H33-74 anchor record contains

• The 32-byte commitment from the receipt (or a Merkle root if batched).
• Sufficient on-chain bytes for a third party to verify the commitment matches the receipt.
• A timestamp from the Solana block, providing independent proof that the receipt existed by no later than that block.

What it does not contain: sensitive payload data. The receipt's content lives off-chain. The anchor only commits to its existence and identity.

When Solana is the right anchor

Solana is the right anchor for high-volume operational evidence (millions of receipts per day), when sub-minute notarization latency is required, and when the operator can tolerate Solana's finality model in exchange for throughput and cost. Especially appropriate for AI decision systems, fraud-scoring pipelines, and compliance engines producing high-frequency receipts.

The portability story

A receipt anchored on Solana can also be anchored on Bitcoin, Ethereum, Solana, Polygon zkEVM, Zcash, or any other chain H33-74 supports. The anchors are independent. Adding more anchors does not change the receipt. Removing one anchor (or having one chain become unavailable) does not invalidate the others.

If Solana ever becomes inappropriate for an operator's use case (regulatory, performance, security, cost), the operator adds an anchor on a different chain and continues operating. The historical evidence does not have to migrate, because it was never bound to Solana.

Verifying a Solana anchor

A third-party verifier needs the H33-74 receipt, the Solana anchor transaction (or its hash), and the open-source H33 verifier. From those inputs:

• The verifier checks the three post-quantum signatures over the receipt (ML-DSA-65, FALCON-512, SLH-DSA-128f).
• The verifier checks that the Solana anchor transaction commits to the receipt's identity.
• The verifier reads the Solana block timestamp to establish independent existence-time.

None of those steps depends on H33's infrastructure. The verifier is open-source and the chain is public.
