Don't trust us. Check.

Verify it yourself

Python, no dependencies. It walks the whole chain and fails loudly if any row was changed.

import hashlib, json, urllib.request
prev, seq = "0" * 64, 0
while True:
    req = urllib.request.Request(f"https://signals.sex/api/v1/ledger?after={seq}", headers={"User-Agent": "ledger-verify/1"})
    rows = json.load(urllib.request.urlopen(req))["result"]
    if not rows: break
    for r in rows:
        assert r["prev"] == prev, f"chain broken at seq {r['seq']}"
        h = hashlib.sha256((prev + r["kind"] + r["key"] + r["body"]).encode()).hexdigest()
        assert h == r["hash"], f"row {r['seq']} was altered"
        prev, seq = h, r["seq"]
print("ledger intact,", seq, "rows, head", prev)

Raw rows: /api/v1/ledger · each body is canonical JSON · hash = sha256(prev + kind + key + body)
