| # appendpage/ledger |
|
|
| Public mirror of every page on [append.page](https://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: |
|
|
| ```bash |
| python verify.py pages/advisors.jsonl |
| ``` |
|
|
| Chain plus every body commitment (the full integrity check): |
|
|
| ```bash |
| 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 |
|
|
| ```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") |
| ``` |
