Corpus attestation

Goblin House — Corpus Merkle root, 2026-10-03

Daily cryptographic attestation over every sources row in the platform's archive. Anyone can rebuild this root from the platform's public source receipts and verify that the corpus on that date hashed to exactly this string. If it doesn't match, the corpus has been altered.

How to verify this attestation

  1. Pull every source receipt for id in [1..80,465]:
    for id in 1..80465; do
      curl -s https://www.goblinhouse.net/source/$id/receipt.json | jq -r '.custody.contentHash // empty'
    done > leaves.txt
  2. Compute the Merkle root over the resulting hex hashes — sorted ascending by source.id, hashed as raw hex strings (no decoding), Bitcoin-style odd-level duplication. Reference implementation:
    function pairHash(l, r) { return sha256(l + r) }
    function root(level) {
      while (level.length > 1) {
        const next = []
        for (let i = 0; i < level.length; i += 2)
          next.push(pairHash(level[i], level[i + 1] ?? level[i]))
        level = next
      }
      return level[0]
    }
  3. Compare the computed root to b1e16348e03cd5c5bc28e501… above. If they match, the corpus on 2026-10-03 contained exactly the documents whose hashes you fetched. If they don't, one or more documents have been altered, removed, or added since the attestation was published.

The signature is a server-side HMAC — it prevents one curator from silently swapping the row, but it does NOT prove third-party-verifiable integrity (we hold the key). For that, future versions will swap to an asymmetric signature with a publicly-pinned verification key.
