PermaledgrPowered by Hyperledger Fabric
Cannabis chain of custody,
on an immutable ledger.
Permaledgr records every batch movement — from harvest to retail — on a permissioned blockchain. Regulators, partners, and consumers can verify provenance instantly.
Verify a batch — no account required
How it works
Register your organization
Join the permissioned Fabric network with your license type, number, and state. Contact details enable automated transfer notifications.
Record every movement
Create batches at harvest. Transfer, split, or merge as product changes hands. Every action is endorsed by multiple orgs before committing to the ledger.
Verify instantly
Scan a batch QR code to view its complete, tamper-proof chain of custody — no account required. Labs issue on-chain COAs. Regulators get an immutable audit trail.
Built for regulated supply chains
Immutable Chain of Custody
Every transfer, split, and merge is recorded permanently on Hyperledger Fabric. No one can alter the history.
Multi-Org Endorsement
Transactions require sign-off from multiple licensed organizations before being committed to the ledger.
Public Provenance
Share a QR code with any batch. Anyone can verify its full history without needing an account.
Certificate of Analysis
Lab-licensed orgs issue COAs directly on-chain, permanently linking test results to the batch record.
Partial Transfers
Transfer a portion of a batch. A child batch is automatically created on the ledger for the remainder.
Merge & Split
Combine multiple batches into one output, or divide a batch into weighted portions — all on-chain.
