BLACKCOIN / PROTOCOL V4VERIFY

TRUST NOTHING / REPRODUCE EVERYTHING

Every number here is reproducible on your own node.

This observatory never asks for trust. Run the signed-source v30.1.3 release from the downloads rail, let it sync, and the commands below reproduce the exact values this site publishes — snapshot by snapshot, block by block. The v30.1.3 source commit and tag are SSH-signed by Blackcoin-Dev; the packaged binaries are not code-signed or notarized, so verify the checksums and the signed source before you run anything.

The reproduction contract

  1. Anchor and tip. blackcoin-cli getblockchaininfo — compare blocks and bestblockhash with the anchor shown in the live ledger and in /api/v3/quantum.
  2. Shadow state. blackcoin-cli getgoldrushstate — the pools, counts, and target bits must equal the snapshot fields exactly. The schema-12 replay_state block, including its commitment hash, is the same attestation shown in the Authenticated Replay Integrity panel.
  3. UTXO commitment. blackcoin-cli gettxoutsetinfo muhash — at any shared height, your muhash must match any other honest node's. This is the strongest single check that your view of the chain is the chain.
  4. Any block, transaction, or payout. getgoldrushblock <height>, getrawtransaction <txid> 2, getshadowtransaction <synthetic_txid>, getshadowaddress <address> — each explorer record cites the exact identifiers to feed these calls.
  5. Supply. gettxoutsetinfo muhash reports total_amount — the same base-chain figure served at /api/supply. Synthetic Gold Rush credits are phase-locked and excluded until Migration; getshadowsupply reproduces that ledger.
  6. The release itself. Verify SHA256SUMS.txt, the SSH-signed source commit and tag, the SPDX SBOM, and the build-provenance attestation from the release record before running anything.

If any command disagrees with what this site shows, the site is wrong — file it on the issue tracker ↗ with both outputs. Fail-closed means we would rather show nothing than something you cannot reproduce.
