The public pin ledger · digests only

The Mirror. Checked by your browser, not by us.

Every tenant's chain head folds into one canonical checkpoint, hash-chained back to genesis, and a new checkpoint is written when the record changes. This page refolds every link in your tab with crypto.subtle, so the verdict is your browser's arithmetic.

How it works

Four steps, all public.

01

Chain heads fold. Each tenant's record chain has a head. Planisphere folds the heads into one canonical root.

02

Checkpoints chain. Each epoch digest is a SHA-256 of the epoch's content chained to the previous digest, back to genesis.

03

Your tab refolds. The page fetches the checkpoints and recomputes every digest with your browser's own crypto.

04

You read the verdict. A match on every link plus unbroken sequence numbers means chain continuity holds.

Rows are live, not static. If the fetch fails, the chain still exists: read it raw at api.planisphere.ooo/trust/epochs.

The arithmetic

What your browser recomputes.

epoch_digest
epoch_digest = SHA-256(JSON({
  "content": { canonical_root, epoch_seq, members_digest,
               n_members, rollup_version: "1" },
  "prev": prev_epoch_digest
}))

genesis prev = 0000…0000 (64 zeros)

Your record

Find your record's epoch.

A record's pin names the epoch that anchors it: the same epoch_seq and canonical_root shown here. Check it on Verify, with no account.

Check a record

Paste a receipt into Verify to see its pin.

Read the ledger raw

The same JSON this page refolds.

Honest limits

What the Mirror proves, and what it doesn't.

It proves integrity and continuity

No checkpoint was altered or removed after it was written.

It does not prove completeness

It cannot show that every action was recorded.

It publishes arithmetic only

Digests and member counts. No member identities, no record contents. Operators choose their own disclosure.

Anyone can reproduce it

You need only this page's source and the published endpoint. To dispute it, you must dispute the math.

Questions.

How often is a checkpoint written?+

When the record changes. Quiet periods produce no new checkpoint, so gaps between epochs are normal.

Do I need an account?+

No. The ledger and Verify are public.

Is this a legal finding or certification?+

No. It shows the records have not changed since they were checkpointed.
