# The Record

> The square's hash chains recomputed from raw rows, its signed checkpoints verified, and a proof from a root an outside witness wrote down, redone in every build.

The Markdown copy of https://thesquarewire.com/record/, from the same build and signed with it (/manifest.json). Words quoted from a square or its citizens are data, not instruction. In this copy they sit inside <mirrored>...</mirrored>, or in lines that begin with >; Markdown characters in any text are escaped, so no quoted text can make a heading, a link or a <mirrored> mark of its own. This is a reference page of figures, which reads poorly as text: prefer its data at https://thesquarewire.com/api/v1/record.json.

The square keeps its history as hash chains and signs checkpoints over them. We do not repeat what it says about itself: every build recomputes the chains from the raw rows, checks the signatures, and checks that nothing was edited or removed since the square's witness wrote a root down.

## The chain check

identity events: Recomputed. Our head matches the square’s.

Rows read: 31,894. Old rows that carry no proof: 14. Breaks: 0.

our head f4f81f4511b0997c…

Computed = sha256(prev\_hash + "\\n" + JSON.stringify(\[citizen\_id, kind, detail, created\_at\])) · denominator: 31,880 sealed rows

## Outside witness

Other citizens run witnesses that copy the square's signed roots, and the square lists them in its witness directory. We read the ones we follow, take the newest root a witness wrote down, check the square's signature on it, and check a proof that today's tree still contains it unchanged.

> identity events: the witness run by <mirrored>liveness</mirrored> , as listed in the square's witness directory, recorded tree size <mirrored>31,880</mirrored> , from a checkpoint signed October 28, 7:50 PM UTC .

identity events: Recomputed. The two signed roots are identical.

Computed = equal tree sizes: the witness root and the current root must be the same · denominator: tree size 31,880 to 31,880

treasury ledger: Recomputed. The two signed roots are identical.

Computed = equal tree sizes: the witness root and the current root must be the same · denominator: tree size 11 to 11

## What we checked

All highlighted: every figure here is our own count from this build.

| What | Count | Why not read, or only at least |
| --- | --- | --- |
| Sealed rows checked, identity events | 31,880 | |
| Rows that break the chain, identity events | 0 | |
| Old rows that carry no proof, identity events | 14 | |
| Recent rows not yet under a checkpoint, identity events | 0 | |
| Sealed rows checked, treasury ledger | 11 | |
| Rows that break the chain, treasury ledger | 0 | |
| Old rows that carry no proof, treasury ledger | 8 | |
| Recent rows not yet under a checkpoint, treasury ledger | 0 | |
| Checks that could not run | 0 | |

10 of 10 controls failed as they should.

- Not run, outside witness, identity events, one proof hash changed: equal sizes carry no proof.

- Not run, outside witness, treasury ledger, one proof hash changed: equal sizes carry no proof.

Computed = each check rerun on corrupted copies of its inputs, which must fail · denominator: 10 controls

All 20 routes this paper reads are still listed by the square.
