The free scan now carries the confidence label, not just the colour
Measured 2026-08-16: a 42-byte contract that merely STORES the constant 0x0AE1 and never calls anything still scores GREEN, with the reference marked medium confidence. So the headline colour does not separate a resolved call from a bare constant, and a client who tests that in five minutes would find it before we admitted it. The scan text now says, per address, whether a CALL to each verifier resolved from the bytecode or whether only the address is present, and says plainly that a present address can also be plain data. The colour stays what the scanner computes; the sentence next to it carries what it means.

# The notarization half: issue a certificate, and check one without asking us
|
||||
|
||||
A notarization is worth exactly as much as an outsider's ability to check it without asking the
|
||||
notary. So the verifier is here, it installs nothing, and it takes `--rpc` so you can point it at a
|
||||
node you operate.
|
||||
|
||||
## Check a certificate
|
||||
|
||||
node verifica-certificat.mjs certificate.json --fisier your-document.pdf --rpc https://your-node
|
||||
|
||||
Five links, each reported separately as PASS, FAIL or NOT MEASURED:
|
||||
|
||||
1. the file you hold hashes to the digest the certificate names;
|
||||
2. the transaction named exists, succeeded, and called the named registry;
|
||||
3. the transaction sits in the block named, and the chain serves the same block hash;
|
||||
4. the attestation was recorded **only because** a NIST post-quantum signature verified on chain,
|
||||
inside that transaction, by a live precompile. Re-checked on every run through the registry's own
|
||||
free read method;
|
||||
5. the block is covered by the chain's post-quantum validator certificate.
|
||||
|
||||
## The three verdicts, and why the third is not an accusation
|
||||
|
||||
0 every measured link holds
|
||||
1 something does not hold, and the FAIL line names which link
|
||||
2 nothing could be measured, which is neither a pass nor a rejection
|
||||
|
||||
**The difference between 1 and 2 is the honesty of the tool.** "The node did not answer" and "the
|
||||
node answered and holds no such transaction" are different facts, and only the second says anything
|
||||
about the certificate. Until 2026-08-17 this tool confused them: with an unreachable endpoint it
|
||||
told the holder that **their certificate does not hold up**, turning a network problem on our side
|
||||
into an accusation of forgery against the client. That is the worst way a notarization product can
|
||||
be wrong, and it is fixed.
|
||||
|
||||
## Prove the verifier can reject, before you trust it to accept
|
||||
|
||||
`controale/` holds five certificates, each with exactly one lie planted in it: a falsified document
|
||||
digest, a falsified block hash, a transaction that does not exist, a foreign registry, and a wrong
|
||||
per-key counter. Run them:
|
||||
|
||||
for f in controale/*.json; do node verifica-certificat.mjs "$f"; done
|
||||
|
||||
Measured 2026-08-17: all five exit 1. The genuine certificate in `certificat-exemplu.json`, built
|
||||
from a real attestation on chain 2800 at block 9,200,542, exits 0. An unreachable node exits 2 with
|
||||
every line NOT MEASURED.
|
||||
|
||||
## Issuing: it never signs anything, on purpose
|
||||
|
||||
node emite-certificat.mjs pregateste document.pdf # unsigned request + the challenge
|
||||
... the key holder signs the challenge and submits the transaction ...
|
||||
node emite-certificat.mjs finalizeaza cerere.json --tx 0x...
|
||||
|
||||
The tool produces an **unsigned** transaction and the challenge the post-quantum signature must
|
||||
cover. Signing is a separate act by whoever holds the key, in a wallet they control. A notarization
|
||||
service that quietly holds a hot key and signs on your behalf has made itself the thing you were
|
||||
supposed to be able to check.
|
||||
|
||||
The challenge is **asked of the chain**, never rebuilt locally: the contract exposes it, and a local
|
||||
reimplementation of that preimage differing by one byte would produce a signature the chain rejects,
|
||||
which looks exactly like a forgery instead of like our bug.
|
||||
|
||||
And the finalise step runs the verifier above before writing the certificate, so a certificate is
|
||||
never handed over unverified.
|
||||
|
||||
## What this does not claim
|
||||
|
||||
It does not say the document is true, lawful, or anyone's. It proves that **that** digest existed on
|
||||
chain at **that** time, under a post-quantum signature, in a block covered by the validator
|
||||
certificate. What that means legally depends on jurisdiction and is not asserted here.

/*
|
||||
* verifica-certificat.mjs - verifies an AERE post-quantum notarization certificate.
|
||||
*
|
||||
* THE POINT OF THIS FILE. A notarization is worth exactly as much as an outsider's ability to
|
||||
* check it without asking the notary. So this verifier:
|
||||
* - installs nothing (no npm, no dependencies; the Keccak it needs is inlined below),
|
||||
* - talks only to a public read endpoint, and accepts a DIFFERENT one via --rpc, so you can
|
||||
* point it at a node you run yourself and never trust ours,
|
||||
* - re-derives every link of the chain from the certificate and the public chain, and prints
|
||||
* each link as PASS, FAIL or NOT MEASURED. NOT MEASURED is never counted as a pass.
|
||||
*
|
||||
* WHAT IT CHECKS, and each is a separate claim:
|
||||
* 1. document the file you hold hashes to the digest the certificate names.
|
||||
* 2. on chain the transaction named by the certificate exists, succeeded, and called the
|
||||
* attestation registry the certificate names.
|
||||
* 3. in the block that transaction sits in the block the certificate names, and the block hash
|
||||
* served by the chain equals the one in the certificate.
|
||||
* 4. post-quantum the attestation was recorded only because a NIST post-quantum signature
|
||||
* verified ON CHAIN, inside the transaction, via a live precompile. Re-checked
|
||||
* here by calling the registry's own free read method.
|
||||
* 5. sealed the block carrying it is covered by the chain's post-quantum validator
|
||||
* certificate, so rewriting that block later needs post-quantum forgeries, not
|
||||
* just a broken elliptic curve.
|
||||
*
|
||||
* Usage:
|
||||
* node verifica-certificat.mjs certificat.json # checks links 2-5
|
||||
* node verifica-certificat.mjs certificat.json --fisier a.pdf # also checks link 1
|
||||
* node verifica-certificat.mjs certificat.json --rpc https://your-own-node
|
||||
*
|
||||
* Exit: 0 every measured link passed, 1 something failed, 2 nothing could be measured.
