A bridge between real achievements and the blockchain

A blockchain can store and transfer value, but it knows nothing about the real world. For a person's achievement to become an asset, someone has to record it on the network honestly. That is the job of the Holdmark oracle.

01 · The trust problem

Any record is worth exactly as much as its source

A diploma screenshot can be forged, a self-declared rating can be drawn. That is why Holdmark does not accept data from users. We accept it only from issuers — the organisations that awarded the achievements: the university signs the diploma, the olympiad committee the result, the testing centre the score, the tech park the grant.

02 · How the oracle works

Four steps from the source's signature to verification by anyone

  1. The source signs.

    Through an integration (API / secure cabinet) the issuer certifies the fact with its digital signature. The signature is cryptographic proof that the record was made by that issuer.

  2. The oracle verifies and relays.

    The Holdmark oracle checks the issuer's signature, the format and the consistency of the data — and writes the credential to the blockchain. Neither the platform nor the person can alter the record after the fact.

  3. The record becomes a credential.

    Every fact lives on-chain as a separate credential with an address, a date and the source's signature. Credentials are assembled into the person's passport and the Holdmark Score is computed.

  4. Anyone can verify.

    An investor, a fund or a regulator checks in one click who issued the record, when, and whether it has changed. Trust stops being a matter of the platform's reputation — it becomes mathematics.

03 · The same for companies

The same rails work for company cases: the issuer's financial and operating figures (revenue, assets, statuses) are verified at the source and recorded on-chain. So a tokenised Astana Hub or VK Cloud asset rests on verifiable data, not on a slide deck.
