Cryptographic dispute evidence for autonomous fleets.
When a robot causes an incident — a delivery goes missing, an AMR damages inventory, an AV is involved in a collision — the question that decides who pays is always the same: where was it, exactly, and can you prove it?
GridStamp is the evidence layer. Every operation produces a tamper-evident spatial receipt: HMAC-signed camera frames, Merkle-rooted memory, cryptographic proof-of-location. The receipts hold up under replay, adversarial patches, depth-injection, and GPS spoofing — tested at fleet scale.
In a 92-day simulation with 5,500 agents across 20 fleets and 8 cities, parameterised with publicly disclosed fleet data from Waymo, Tesla, Starship Technologies, Coco Robotics, Serve Robotics, and commercial drone operators (GridStamp is not affiliated with or endorsed by any of them; parameters come from public filings and press releases):
- 14.55M operations processed (fleet simulation)
- 99,911 operations in 43 seconds — 2,323 ops/sec (100K stress test)
- 100% replay detection, 100% HMAC tamper detection, 100% verification pass
- 200 concurrent robots, 80,000 proof chain links, all chains valid
- p99 latency: 0.86ms per spatial proof generation
- 707 tests passing; 221 SDK tests + 100K production stress bench
Receipts are designed to be admissible-grade evidence for insurance disputes, SLA audits, and regulatory investigations. Final admissibility is jurisdiction-dependent and should be confirmed with counsel for your underwriting market.
| Buyer | Problem GridStamp solves |
|---|---|
| AV / robotics insurance underwriters | Reduce loss ratio by resolving location-of-incident disputes with cryptographic evidence instead of he-said/she-said. |
| Logistics visibility platforms (freight, last-mile) | Give shippers verifiable proof-of-delivery their customers can't dispute — upgrade ETAs from claims to receipts. |
| AR gaming & location-based apps | Stop the ~9% of top players who GPS-spoof. Our stress test catches 91% of spoof attempts. |

Six layers, each cryptographically isolated:
| Layer | What it does |
|---|---|
| Perception | HMAC-signed camera frames, stereo depth fusion, dual-camera support |
| Memory | 3-tier spatial memory (short/mid/long-term) with Merkle tree integrity |
| Navigation | A* and RRT* pathfinding on 3D occupancy grids, place cells + grid cells |
| Verification | SSIM + LPIPS + depth comparison for spatial proof-of-location |
| Anti-Spoofing | Replay detection, adversarial patch detection, depth injection, canary honeypots |
| Gamification | Trust tiers, capability badges, streak multipliers, zone mastery, fleet leaderboard |
npm install gridstampimport { createAgent } from 'gridstamp';
const agent = createAgent({
robotId: 'DLV-001',
cameras: [{ type: 'oak-d-pro', role: 'foveal', /* ... */ }],
hmacSecret: process.env.GRIDSTAMP_SECRET, // min 32 chars
}, cameraDriver);
// Capture and verify
const frame = await agent.see();
const proof = await agent.verifySpatial();
// Settle payment only if spatial proof passes
const settlement = await agent.settle({
amount: 15.00,
currency: 'USD',
payeeId: 'merchant-001',
spatialProof: true,
});Robots earn trust through verified operations, similar to a credit score:
| Tier | Points | Fee | Max Tx | Verification |
|---|---|---|---|---|
| Untrusted | 0 | 2.5x | $10 | Every operation |
| Probation | 100 | 2.0x | $50 | Every operation |
| Verified | 500 | 1.5x | $200 | Every 3rd |
| Trusted | 2,000 | 1.2x | $1,000 | Every 5th |
| Elite | 5,000 | 1.0x | $5,000 | Every 10th |
| Autonomous | 10,000 | 0.8x | $25,000 | Spot checks |
All tier changes are HMAC-signed. Spoofing attempts result in immediate two-tier demotion.
Every spatial proof links to the previous via SHA-256 hash chain. A robot's entire operational history becomes a tamper-evident linked list — if any proof is modified, the chain breaks.
import { ProofChain } from 'gridstamp';
const chain = new ProofChain();
chain.append(proof1); // genesis
chain.append(proof2); // links to proof1
chain.append(proof3); // links to proof2
const result = chain.verify();
// → { valid: true, chainIntegrity: 1.0, length: 3 }This means a fleet operator or insurance underwriter can verify the complete history of a robot's spatial claims — not just individual proofs, but the unbroken chain between them.
- Every camera frame is HMAC-SHA256 signed at capture time
- Cryptographic key derivation isolates subsystems (
deriveKey(master, 'frame-signing')) - Monotonic sequence numbers prevent replay attacks
- Canary landmarks detect memory poisoning
- Constant-time HMAC comparison prevents timing attacks
- Fail-closed: any integrity violation blocks payment
