ledger

Public mirror of every page on append.page, pushed roughly every 10 minutes when any chain changes.

For each page slug <slug> you get two files under pages/:

• pages/<slug>.jsonl — the JCS-canonicalized hash chain (one entry per line, hash-committed to its predecessor). Any later edit, deletion, or reorder is mathematically detectable by anyone who kept a prior snapshot (this dataset is one such copy — HuggingFace also keeps full Git history).
• pages/<slug>.bodies.jsonl — the actual post text + per-entry salt, in the same row order as the chain. Erased entries appear with body: null and erased: true; salt is still present so anyone with a private archive of the body from before erasure can re-verify it offline.

Verify a page in one command

Chain only:

python verify.py pages/advisors.jsonl

Chain plus every body commitment (the full integrity check):

python verify.py pages/advisors.jsonl --with-bodies pages/advisors.bodies.jsonl

Exit code 0 means the chain is intact AND every non-erased body satisfies SHA-256(salt || body) == entry.body_commitment. The verifier is self-contained Python (stdlib + the jcs package for RFC 8785 canonicalization) and ships in this repo.

Load into Python

import json
with open("pages/advisors.jsonl") as f:
    entries = [json.loads(line) for line in f if line.strip()]
with open("pages/advisors.bodies.jsonl") as f:
    bodies = [json.loads(line) for line in f if line.strip()]
print(len(entries), "entries,", sum(1 for b in bodies if not b["erased"]), "live bodies")
