Zero-trust
document
verification.
Certification of digital documents of any kind — especially those with legal or financial value. Using blockchain and cryptography, any third party can instantly verify authenticity without contacting the issuing institution.

The problem
Document fraud is a
multi-billion euro problem.
Fake diplomas, forged contracts, backdated agreements, and counterfeit certificates cost institutions, employers, and governments enormous sums every year — and they undermine trust in entire sectors.
Traditional verification relies on contacting the issuing institution — slow, expensive, unreliable, and impossible if the institution no longer exists or their records have been compromised.
The NewCo solution
One blockchain record.
Permanent truth.
NewCo Blockchain Certificates create an immutable, timestamped record of every document's exact content at the moment of certification — stored permanently on the COTIC blockchain.
Any verifier — employer, authority, court, or individual — can check authenticity in under a second, independently, from anywhere in the world, without involving the issuer at all.
Capabilities
Trust you can
build systems on
Cryptographic hash per document
Every document receives a unique SHA-256 fingerprint permanently recorded on the COTIC blockchain — any alteration, however small, changes the hash and invalidates the certificate.
Immutable timestamp
Each certification record includes a blockchain timestamp that cannot be backdated, forged, or altered — providing legally admissible proof of existence at a given moment.
Instant third-party verification
Any verifier worldwide can check a document's authenticity by uploading the file or entering its hash — with results in under one second, without contacting the issuing institution.
No central authority required
Verification is completely decentralised. There is no single point of failure, no intermediary to contact, and no dependency on the issuer remaining in operation.
Batch certification API
Institutions processing large volumes — universities, government agencies, legal registries — can certify thousands of documents per hour via our REST API.
eIDAS 2.0 compatible
Our certification process is aligned with the EU's eIDAS 2.0 regulation for electronic identification and trust services — enabling cross-border recognition across all EU member states.
Process
From document to
blockchain record
Institution submits the document
A digital document is submitted through our secure portal or via the REST API. The document itself is never stored on our servers — only a cryptographic hash (digital fingerprint) is generated client-side and sent to the blockchain.
COTIC blockchain records the hash
A unique SHA-256 hash is generated and written permanently to the COTIC blockchain with a certified timestamp, the institution identifier, and document metadata. This record is immutable — it cannot be changed or deleted.
Certificate and QR code issued
The institution receives a blockchain transaction ID and a verifiable QR code that can be embedded in the physical or digital document. The QR links to the verification portal.
Anyone verifies in under one second
The document recipient — employer, authority, court — uploads the document to the verification portal or scans the QR code. The portal computes the hash and checks it against the blockchain record. The result is instant: authentic, tampered, or revoked.
Who it's for
Every institution
that issues documents
Universities & education
Issue tamper-proof digital diplomas, transcripts, and certificates. Graduates share a verification link — employers confirm authenticity instantly without calling the institution.
Legal & notary services
Certify contracts, deeds, powers of attorney, and sworn translations. Immutable timestamps create irrefutable proof of signing date and document integrity.
Government & public sector
Digitise and certify birth certificates, land registries, permits, and public records. Citizens receive verifiable digital documents that are impossible to counterfeit.
Financial institutions
Certify loan agreements, compliance documents, audit reports, and regulatory filings. Auditors verify document integrity without relying on any party's assertions.
HR & recruitment
Verify employment history, professional qualifications, and references in seconds. Eliminate credential fraud in hiring pipelines with zero manual back-checking.
Healthcare & pharma
Certify clinical trial documents, regulatory submissions, and product approvals — creating an auditable chain of integrity from creation to submission.
Common questions
Frequently asked questions
What types of documents can be certified?
Any digital document in any format (PDF, Word, images, spreadsheets, etc.). The system certifies the content hash, not the format — so file conversions do not affect verification.
What does verification look like for a third party?
The verifier visits our verification portal, uploads the document or pastes the hash, and receives an instant confirmation showing the certification date, the issuing institution, and whether the document matches its original certified state.
Can documents be revoked?
Yes. Issuers can publish a revocation record on the blockchain. Verification then shows the document as revoked, with a timestamp of revocation — maintaining the complete history.
Is this legally valid in the EU?
Our implementation is designed in alignment with eIDAS 2.0 and the EU Blockchain Observatory recommendations. For specific legal admissibility in your jurisdiction, we recommend consulting your legal team — we are happy to provide technical documentation.
How does the API integration work?
We provide a REST API with full OpenAPI specification. Your system submits document hashes (you never send the document itself — only the hash), and receives a blockchain transaction ID for the certification record.
