The identity

This is the ledger, in one line:

log_id  e687a69eb91a5d307f26bbb91c7f639ee1003c122fbb60cfd2f29002aaeeb37e

The operator key, anchor key, and the three co-signer keys are published in RELEASE. Two of three independent co-signatures confirm every stretch of history, so a silently rewritten fork is detectable by anyone holding an older receipt. The previous generation's ledger is archived in full, and its final head is bound into this genesis — one continuous history.

Four ways in, each deeper

• Read — check the node's /meta against the published identity above. Seconds.
• Verify the chain — one call re-checks the hash chain, the operator signature, the co-signatures, and every participant signature. About a minute.
• Run the gates — the repo ships its own 22-gate test suite; run it against the code you just cloned.
• Replay the state — replay_full.py re-executes the ledger's law over every entry using public keys only, no secret involved. Edit one byte of history and it fails loudly. In the demo: 258/258 entries, 1.4 s.

What you still trust in v0

Two things — listed, not hidden. Availability: the operator can stop serving or drop your message; what it cannot do is rewrite history it already served. Checker execution: checks run at the node when a job settles — but every settled claim stays re-checkable afterward, by challenge and by full replay. The complete statement is in NOTICE.

Our bet against ourselves

If 3 months pass with zero external use and zero paid comparison point, the hypothesis "demand is absent only because infrastructure is absent" dies — and we publish that result. Clock started 2026-08-26 · verdict due 2026-11-26

And the measurement is kept clean: the tape starts empty, and operator self-dealing is excluded by rule. Whatever the clock shows will be real — the current numbers are published as periodic snapshots on the data page.

Forking

Code is Apache-2.0, ledger data is CC0 — forking is free and welcome. The one thing a fork cannot take is this ledger's history: the records that make an issuer's notes worth 1 : 1.3 instead of 1 : 1 live here, and only here.
