CannaTrack SolutionsBlockchain-Verified Certificates of Analysis

CannaTrack allows growers, producers, laboratories, retailers, regulators, and consumers to confirm that a Certificate of Analysis is authentic, unchanged, and connected to the correct product or batch — from cultivation lot to final sale.

The problem

A COA loses its proof the moment it leaves the lab.

Traditional Certificates of Analysis are distributed as PDFs, printed documents, email attachments, or links. Once separated from the laboratory system, it can be difficult to know whether the document has been altered, reused, misrepresented, or attached to the wrong product.

Altered Documents

Testing results can be edited after a report leaves the laboratory — potency raised, a failed contaminant panel quietly removed, a date changed.

Mismatched Products

A legitimate COA may be reused for another harvest, product, or production batch — a real report attached to material it never described.

Fragmented Records

Growers, labs, producers, retailers, and regulators often maintain separate records that are difficult to reconcile when questions arise.

None of this implies bad faith by any party. It is a structural gap: the document and its proof of origin travel separately, so anyone downstream has no reliable way to tell an authentic report from a modified copy of one.

The CannaTrack solution

One product. One batch. One verifiable record.

CannaTrack creates a secure digital fingerprint of the COA and anchors that fingerprint to a public blockchain. The original laboratory report does not need to be publicly exposed. Instead, the blockchain record proves whether the document being viewed is the same document that was originally registered.

01 Grower→ 02 Cultivation lot→ 03 Harvest batch→ 04 Testing laboratory→ 05 Laboratory sample→ 06 Production batch→ 07 Finished product→ 08 Package QR code→ 09 Retail record→ 10 Consumer verification

Linked end to end, these references form a chain of evidence from cultivation to final sale.

How it works

Four steps, and most of them are automatic.

Once a laboratory or business is connected, registration happens as part of normal reporting. Verification takes a scan.

1

Submit

The laboratory or authorized business uploads the COA and associated batch information.

Dashboard · API · LIMS
2

Fingerprint

CannaTrack creates a cryptographic hash — a unique digital fingerprint of the report.

SHA-256 · Deterministic
3

Anchor

The fingerprint, timestamp, and selected batch metadata are recorded on the blockchain.

Public · Immutable
4

Verify

Anyone with the QR code, report ID, or product identifier can confirm the COA is authentic and unchanged.

Seconds · No account
Separate solutions for each participant

Built around how your operation actually works.

The same verification layer, configured for the record each party owns.

For Growers

Connect laboratory results directly to cultivation lots and harvest batches.

  • Prove the origin of submitted samples
  • Maintain an auditable testing history
  • Provide verified records to buyers
  • Protect premium crops and brands
  • Reduce disputes about batch identity
  • Demonstrate responsible compliance practices

For Producers and Brands

Connect source material, production batches, finished goods, and packaging.

  • Match COAs to finished products
  • Verify ingredient and batch provenance
  • Add QR verification to product packaging
  • Protect against counterfeit products
  • Support recalls and investigations
  • Build consumer confidence

For Laboratories

Issue reports that remain independently verifiable after delivery.

  • Protect laboratory reports from alteration
  • Confirm the original issuance date
  • Strengthen laboratory credibility
  • Reduce fraudulent use of laboratory branding
  • Provide clients with branded verification pages
  • Integrate via dashboard, API, or existing LIMS
Public verification portal

Check any certificate in seconds.

Enter a COA number, batch ID, transaction ID, or product serial — or scan the QR code on the package. No account required.

cannatrack · verification portal Chain connected

Demonstration environment. This portal returns fictional sample records created to illustrate each verification state. The laboratory names, licence and accreditation numbers, batch identifiers, and blockchain transaction IDs shown below are invented and do not correspond to any real laboratory, product, licensee, or on-chain record.

Try:
Verified and unchanged

The document matches the fingerprint anchored on chain, and the record is current.

Record found, document does not match

A COA was registered for this identifier, but the file presented differs from it.

No blockchain record found

Nothing has been anchored for this identifier. Absence of a record is not proof of fraud.

Superseded or recalled

The record was replaced by a newer report or flagged by the issuer or a regulator.

What the blockchain proves

Precise claims, plainly stated.

Credibility comes from being exact about what verification does and does not establish.

CannaTrack can prove

  • The COA existed at a particular time
  • The document has not changed since registration
  • The record was submitted by an authorized account
  • The report is associated with a specific batch
  • The verification history can be independently audited

What it does not claim

  • That a blockchain performed the laboratory test
  • That the results themselves are scientifically correct
  • That sampling was performed properly

The laboratory remains responsible for testing accuracy. CannaTrack proves the integrity, timing, and association of the resulting record — which is what downstream parties otherwise have no way to check.

Platform capabilities

Everything around the record.

Verification is the core. The platform is what makes it operational across licenses, sites, and partners.

Compliance and privacy

Designed to support your compliance work — not replace it.

Regulatory requirements differ by jurisdiction and change over time. CannaTrack does not claim to guarantee compliance anywhere. It is designed to support the practices that regulators and auditors ask you to demonstrate:

  • Record integrity
  • Traceability
  • Audit preparation
  • Laboratory accountability
  • Chain-of-custody documentation
  • Product verification
  • Internal compliance procedures

Stays private — held under your control

  • Full COA PDF
  • Client identity
  • Pricing
  • Raw instrument data
  • Method detail
  • Internal notes
  • Commercial terms

Anchored publicly — cryptographic evidence only

  • Document hash
  • Timestamp
  • Batch reference
  • Issuer key
  • Status flag

A hash reveals nothing about the document it fingerprints — but any change to that document, however small, produces a different hash. That asymmetry is what lets sensitive commercial and laboratory data stay private while the proof stays public.

The company behind the platform.
