The change is intended to make evidence history easier to inspect—not to prove that a knowledge claim is true. This account is based on contributor Nicola Lorenzini’s September 30, 2026 implementation report, not an independent audit of the repository, contract, production deployment, or reward ledger. Read Lorenzini’s DEV Community report.
What MYZ-209 was intended to change
A Knowledge Card can draw on multiple sources. The implementation described by Lorenzini distinguishes those ordinary evidence records from structured proof attestations, which describe a commitment associated with a payload.

Before the change, evidence identity could be entangled with how records were presented or ordered. The report says MYZ-209 introduced stable SRC-* identifiers so a source could retain its identity across refreshes and reimports. It also aimed to display Proof v2 and Proof v3 as distinct attestations without erasing Proof v2 history or creating duplicate URL nodes.
For classification, the report favors structured fields—such as proof type, version, and role—over labels alone. Text detection remains useful as a fallback for legacy records that lack those fields.

How sources, digests, and attestations differ
- Source: material that supports a knowledge claim. A stable
SRC-*ID helps refer to the same evidence record through graph changes. - Digest: a hash that identifies a particular payload. In the reported Proof v3 example, the digest uses SHA-256.
- Attestation: a structured record that commits to a digest or otherwise records a proof version and role.
- Transaction evidence: a blockchain transaction reference that can help someone inspect whether an attestation was recorded.
The reported verification path is canonical payload → SHA-256 digest → attestation → independent comparison. Someone checking the commitment would need to compare the relevant payload and digest, then inspect the attestation evidence. A digest can identify a payload, and a transaction can provide evidence that an attestation occurred; neither establishes that the claim in the payload is accurate, complete, or well-supported.
“The blockchain reference doesn’t magically prove that the knowledge itself is true.” — Nicola Lorenzini
What the report says Proof v3 contains
For the Knowledge Card discussed in the post, Lorenzini describes Proof v3 as including a SHA-256 digest and an Ethereum Sepolia attestation. The post also lists a contract address and deployment and attestation references associated with the payload and documentation. Those details are the author’s report; the available account does not independently verify the contract, deployment, or live network state.

Proof v2 and Proof v3 are presented as coexisting versions, not as a security ranking. The report describes version-specific grouping and preservation of historical Proof v2 records, with Proof v3 connected to the Knowledge Card. It does not provide a full protocol specification or enough evidence to compare the versions’ security properties generally.

Why graph inspection mattered after the build
Lorenzini says the first implementation built successfully, but inspection of the rendered graph exposed semantic problems that a build alone did not catch:
- Proof v2 appeared in duplicate representations.
- Raw evidence already grouped into a proof still appeared as ordinary source nodes in the proof-filter view.
- The Proof v3 node did not have an edge to its Knowledge Card.
The reported fixes grouped proof evidence by version, hid evidence consumed by a grouped proof from the proof-filter view, and added the missing Proof v3-to-card edge. The distinction is about the filtered proof view: the report says ordinary SRC-* nodes remained visible in the complete graph.
What was reported in production
As of Lorenzini’s September 30, 2026 post, the production Proof filter showed Proof v3, a SHA-256 digest, and Proof v2. The Knowledge Card was connected to Proof v3, and the filtered view had no duplicate raw proof sources. This is a reported state at publication, not a current live check or independent production verification.
Implementation workflow and its limits
The author describes a workflow that included implementation, tests, a Vercel preview, visual graph inspection, fixes, a second preview, final verification, merge, and production verification. According to the post, CI failures were traced to unrelated backend tests, and Daniel Ioni performed final preview verification. These are process details reported by the author, not independent test results.

The account also reports a 250 MYZ contributor reward confirmed by a MyZubster maintainer. Lorenzini says the public ledger entry had not yet been independently located at publication, and characterizes MYZ as an internal accounting unit—not an on-chain token or a fiat payment. The amount therefore should not be read as a verifiable public transfer.

The reported design makes an important modeling distinction visible: sources support knowledge, stable IDs help preserve source identity, and attestations make a payload commitment easier to inspect. For that distinction to be useful, graph structure must reflect the relationships accurately; the author’s account of visual review shows how duplicate nodes or a missing edge can undermine that clarity even when a build passes.
It is a transparency improvement as described by its contributor, not a truth oracle. Verifying a digest or transaction can help establish what payload was committed and whether an attestation was recorded; assessing whether the underlying knowledge is true still requires examining its evidence and reasoning.
