Protocol Walkthrough
The chain,
step by step.
Step 1 / 6
Identity created.
500 serials are registered under batch BCH-49A2. Each serial is cryptographically signed — mathematically bound to this manufacturer, this batch, this moment.
BATCH_REGISTERED
BCH-49A2 → 500 serials assigned
Signature: 7f3a… Hash: a4f2…
Step 2 / 6
Custody transferred.
The batch ships to a regional distributor. The custody claim is accepted by the eligibility gate — both parties are verified, the state is ELIGIBLE.
CLAIM_ACCEPTED
SRL-7F3A → dist-01 (Mumbai CFA)
State: ELIGIBLE Latency: 12ms
Step 3 / 6
Anomaly detected.
A scan event arrives from an unexpected region — Signal 3 fires. The serial was already scanned 400km away 6 minutes ago. This is physically impossible.
SIGNAL_3: DUPLICATE_SCAN
SRL-7F3A flagged → State: RESTRICTED
Distance: 412km Gap: 6min Confidence: HIGH
Step 4 / 6
In transit. Verified.
The legitimate shipment continues. Logistics custody is recorded with GPS coordinates. The hash chain grows. Every transfer is sealed and immutable.
CUSTODY_RECORDED
logistics-07 → pharmacy-12 (Pune)
GPS: 18.5204°N, 73.8567°E Chain: intact
Step 5 / 6
Authenticity confirmed.
The pharmacy scans the serial at point of receipt. Five detection signals run in parallel. All clear. Verification returns ELIGIBLE in 47ms.
VERIFY_RESULT: ELIGIBLE
SRL-7F3A — 4 signals clear
Latency: 47ms Merkle proof: valid Trust: GREEN
Step 6 / 6
Every product. Proven.
The consumer scans the QR code. A certificate is issued — cryptographically provable, independently verifiable, tamper-evident. The supply chain doesn't lie.
CERTIFICATE_ISSUED
SRL-7F3A → consumer verified
Hash: 9c3f… Proof chain confirmed
