Independent verification

Check the record. Trust the chain.

You do not need the Verifyum database to inspect a public anchor. Use the transaction signature stored in the portable proof package or public metadata.

Solana Explorer

Require successful execution, finalized status, the published Verifyum signer and the exact Memo value.

Direct JSON-RPC

Call getTransaction with the transaction signature and inspect the response instead of trusting copied status text.

Portable proof

Use the original file and private manifest to recompute the commitment, then compare it with the finalized Memo transaction.

Direct RPC example

Read the transaction yourself.

curl -s https://api.mainnet-beta.solana.com   -X POST   -H 'Content-Type: application/json'   -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "getTransaction",
    "params": [
      "PASTE_TRANSACTION_SIGNATURE_HERE",
      {
        "commitment": "finalized",
        "encoding": "jsonParsed",
        "maxSupportedTransactionVersion": 0
      }
    ]
  }'

Check meta.err, the transaction signer, the Memo program instruction, the exact memo, the slot and the estimated block time. A block time shows when the commitment entered the block. It does not prove when the original file was created.
