Introducing Sentinel: Trust Infrastructure for Autonomous Machines

2025-01-155 minSentinel Team

The Problem

Robots today are insecure and unverifiable. Enterprises deploying autonomous systems cannot reliably prove which robot performed an action, whether firmware was compromised, whether telemetry is authentic, or whether logs are trustworthy.

This becomes critical in warehouses, drone delivery, autonomous vehicles, industrial systems, and robotics fleets operating at scale.

What We Built

Sentinel is the trust infrastructure layer for autonomous machines. Every robot gets:

  • Cryptographic identity — Ed25519 keypair + W3C DID registration
  • Signed action logs — every event cryptographically signed and timestamped
  • Firmware verification — SHA-256 hash verification with on-chain proofs
  • Trust scoring — dynamic 0-100 score based on behavior and attestation
  • Immutable audit trail — hash-chained logs anchored on Solana

Architecture

We use a hybrid on-chain/off-chain architecture:

  • On-chain (Solana): Robot DIDs, firmware proofs, trust state, signatures
  • Off-chain (PostgreSQL): Telemetry, logs, analytics, fleet data

This gives us the immutability of blockchain with the performance of traditional databases.

What's Next

We're starting with robotics startups who need fleet management, auth, telemetry, and compliance. Phase 2 expands into warehouses and logistics. Phase 3 targets defense and industrial sectors.
