AgroTrace
Prove where your harvest came from. AgroTrace is blockchain traceability for Indian agricultural exports, mango and turmeric, that follows a consignment backward to the farm and forward to the buyer through every change of custody. Every event is recorded where and when it happens and anchored on a tamper-evident ledger, so origin and quality claims rest on evidence rather than paper. No external chain, no token, no gas.
Two commodity chains. One engine.
Turmeric and mango run on the same engine today, each with its own workflow, roles, quality parameters and regulatory requirements, with more crops added as data rather than code.
2 chains
Turmeric & mango, one engine
Turmeric runs 14 stages, mango runs 12, each with its own roles, quality parameters and regulatory set. New crops are added as data, not code.
1 unit
The harvest batch
One traceable origin unit per chain, registered by the farmer, with nothing recorded before it.
On chain
Anchored, not asserted
Every record is anchored on an internal permissioned ledger with hash-linked blocks and a signed consensus round.
2 party
Custody as agreement
Every handoff is a two-party custody transfer the receiver accepts or disputes, co-signed on the ledger.
QR
Public verification
Any consignment is verifiable from a QR code, with the full journey, certificates and laboratory results.
Alerts
Quality on the record
On-chain quality assays, a maximum-residue-limit panel per commodity, and an IoT breach alert before the vessel departs.
The record keeps breaking where custody changes.
Indian agricultural exports are worth billions a year, yet each break in the record carries a cost, and a single import alert abroad can place every later consignment under detention on arrival. AgroTrace addresses each gap.
01.
Origin claims on paper
A certificate of origin or a Spices Board registration moves as a paper document, which invites duplicate presentation, quantity inflation and transcription error.
02.
Lost batch identity
Several field lots merge on a grading or polishing floor within one shift, so a finished carton can no longer be traced back to a source farm.
03.
Unrecorded quality events
A residue reading, a moisture reading or a treatment goes unwritten and surfaces months later as a rejection at a foreign port.
04.
Adulteration and residues
Lead chromate colouring in turmeric, ethylene oxide fumigation banned by the EU, or a pesticide over the market limit on mango, none of it visible until arrival.
05.
Contamination in transit
A humidity spike raises aflatoxin risk in turmeric, or a cold-chain break spoils mango, with no reading on the record to catch it in time.
06.
Disputes at the handoff
A grower declares one weight and grade, the next party receives another, and the disagreement surfaces at the end of the chain rather than the moment it happened.
Every actor. Every stage. One chain.
Every step follows the same shape: record, validate, anchor, hand off, accept or flag, finalise, verify. Switch between the two commodity chains to see each ordered stage, its actor and where custody passes.
The traceable unit is the harvest batch. 14 ordered stages, from the Armoor and Nizamabad belt to the destination port. Drying and the quality assay are performed on the finished product late in the chain.

The essential difference: turmeric is tested late, on the finished powder, and adds boiling, drying, polishing, mandi sale, grinding and Spices Board certification. Mango is tested early, on the raw fruit, and adds packhouse grading, disinfestation treatment, NPPO phytosanitary clearance and APEDA certification. The downstream logistics tail is shared.
Built for every actor in the chain.
Batch & Consignment Management
Register the harvest batch at the farm with cultivar or GI variety, location, harvest date and quantity, then assemble the export consignment from a certified batch. Each carries a QR code, scannable at any point to pull the full history.
Compliance Scorecard
Each mandatory check is scored pass or fail against a configurable MRL panel per commodity, curcumin, lead chromate, ethylene oxide and aflatoxin for turmeric, the pesticide panel for mango, aligned to FSSAI, EU, US, Japan and Codex limits. Catch violations before the vessel is loaded.
IoT Monitoring & Alerts
Rules run automatically as data is recorded. A humidity spike that raises aflatoxin risk in turmeric transit, or a cold-chain excursion for mango, is flagged before the vessel departs so the container can be held.
Two-Party Handoffs & Disputes
Custody does not advance silently. The unit lands in the receiver's acceptance queue; they accept, co-signing quantity and grade on chain, or flag a discrepancy, which opens a dispute both parties work from on the same immutable record.
Role-Scoped Workspaces
Every party in the chain has an account and a workspace scoped to their own work, farmer, boiling and drying and polishing units, mandi, processing unit, packhouse, treatment facility, laboratory, regulators and the overseas buyer, so the record is built by the people who hold the produce.
Public Verification
Anyone can verify a consignment at agrotrace.cerulea.io without logging in. The page shows the compliance scorecard, the full farm-to-shore journey, the certificates and the laboratory results, including the verified curcumin figure for turmeric.
Profile-Driven Engine
A thin engine interprets a declarative profile that defines a whole commodity chain, its entities, roles, stages and rules. Adding a crop is writing a profile, not changing the engine, so the same platform grows beyond mango and turmeric.
Multilingual PWA
Localised across nine Indian languages and delivered as an installable progressive web app that works on a phone, so the actor who holds the produce can capture the record in the field, in their own language.
The blockchain layer inside AgroTrace.
AgroChain is an entirely internal, permissioned ledger with no external dependencies, no gas fees and no wallet setup. Every event produces a transaction, hashed with SHA-256 and signed by the acting party, gathered into a block with a Merkle root and a hash link to the block before it, and finalised by a signed consensus round.
Consensus
4-of-5 validator set
A five-node validator set signs each block; a block is finalised only when it reaches the four-of-five threshold, otherwise its transactions return to the mempool.
Integrity under load
Single producer, one chain head
Block production runs on a single producer with an in-process guard on the true chain head, so a burst of records cannot fork or wedge the chain, and any unfinalised block is recovered on restart.
Integrity
SHA-256 Merkle tree
Every transaction is hashed and signed, every block carries a Merkle root and a hash link to the previous block, all the way back to a genesis block.
Document anchoring
Digest on chain, file off chain
Certificates and documents are anchored by their SHA-256 digest, so the original file can be checked against the ledger without storing it on chain.
5-Node Validator Set, 4-of-5 to Finalise
Anyone can verify. No login required.
Every consignment carries a QR code that resolves to a public verification page. A buyer, an auditor or an importing authority can check the full journey from farm to foreign shore, the certificates, and the laboratory results, each reading against its limit, with no account and no blind trust. A separate chain explorer lets anyone re-confirm that every block is hash-linked to the one before it.
