CYRQODE: event journal and proof
CYRQODE proves what really happened: one mark on a product and a chain of immutable events — who made it, from what, under whose approval and when.
Tell us what needs to be proven in your process. We will come back with a connection option: marks, your own ledger on the protocol, or the CYRQODE ledger.
In short
CYRQODE is a BizDNAi technology: one mark on a product with a chain of immutable events behind it — what happened, in what relation, under whose authority.
Every accounting system answers 'what is recorded'. CYRQODE answers a different question: what actually happened and whether it can be proven a year from now.
A record proves that a document with exactly this content existed on the stated date without storing the document: the journal holds a SHA-256, not the content.
Personal data never enters the journal: an event refers to an entity identifier, not to a person.
What CYRQODE consists of
| Element | What it is |
|---|---|
| CYRQODE | brand of the technology |
| BUIP | protocol of identity, events and proofs |
| Circle Mark | physical sign carrying a stable entity identifier |
| BizDNAi | owner of the technology |
How it works
The mark encodes exactly one entity identifier — a UUID — plus the profile's service fields. Name, date, author, price, expiry date and any text are not in the mark: all of that changes, the mark does not.
A journal record contains the fact, the time, participants as identifiers and references to evidence as hashes. There is no personal data, no document content and no commercial terms in the journal.
What a record proves
The record proves that a document with exactly this content existed on the stated date without storing the document itself. Anyone can check: compute the SHA-256 of their own copy and compare it with the record.
The technology can prove that an action was performed by an entity with the proper permit at the proper time — knowing neither the name nor the position.
Proof levels
The first journal record (6 September 2026) has proof level PL-0 — an owner statement. Signatures and independent witnessing are a later layer, and the record page states this explicitly.
What is public and what is not
Licences: specification and schemas — CC BY 4.0, code — Apache 2.0.
Rule in case of doubt: if it belongs to the protocol — public, if it belongs to operations — private. You can open the closed at any time; you cannot close the open.
| Public | Private |
|---|---|
| protocol specification, schemas, test vectors | ledger core, resolver, projections and aggregates |
| client libraries, mark generator, scanner | access policies, operations |
| demonstrational registry records | data of specific legal entities |
How to connect
| Option | What is needed |
|---|---|
| Marks only, no ledger | You generate marks and read them in your own system; no agreements needed — the licences allow it |
| Your own ledger on the protocol | You implement storage yourself while following the event format, canonicalization and signature |
| The CYRQODE ledger | You send events to the service and use the ready resolver; the service address, namespace identifier and credentials are required |
Two principles
The core is industry-neutral: manufacturing is the first and most saturated consumer, but not the subject of the protocol. Manufacturing fields live in a separate profile.
Personal data never enters the ledger: an event refers to an entity identifier, not to a person.
Frequently asked questions
What is CYRQODE in simple terms?+
A mark on a product and an event journal behind it. The mark lets you prove what really happened: what it is made of, who made it, on which equipment, under whose approval, with which documents.
How is it different from an accounting system?+
An accounting system answers 'what is recorded'. CYRQODE answers a different question: what happened, in what relation to everything else, under whose authority, and whether it can be proven a year from now.
Does personal data enter the journal?+
No. An event refers to an entity identifier, not to a person. Only the data owner knows the name and position in their own system.
Does CYRQODE store the documents themselves?+
No. The journal holds the document's SHA-256. The record proves that a document with this content existed on the date without storing the document itself.
Can we use marks only, without a ledger?+
Yes. You can generate marks and read them in your own system — the licences allow it, with no agreements required.
