Architectural Comparison
IoT Authentication: Traditional API Keys vs. Decentralized Identity
A technical and operational comparison of legacy centralized authentication versus modern decentralized identity for IoT device management and secure payment authorization.
| Authentication Factor | Traditional API Keys | Decentralized Identity (DID) |
|---|---|---|
Architecture | Centralized Server | Decentralized Ledger |
Security Model | Single Point of Failure | Cryptographic Proof-of-Ownership |
Credential Lifecycle | Manual Rotation & Revocation | Programmatic, On-Chain Revocation |
Device Onboarding | Manual Provisioning (High Touch) | Self-Sovereign, Automated |
Attack Surface | Database Breach, Key Leakage | Private Key Compromise Only |
Audit Trail | Centralized Logs (Mutable) | Immutable On-Chain History |
Interoperability | Vendor-Locked, Proprietary | W3C Standard (DID, VC) |
Implementation Time | 4-6 weeks (Custom Backend) | 2-3 weeks (SDK Integration) |
Ongoing OpEx | High (Server, DB, Security Patching) | Low (Gas Fees Only) |
Scalability Limit | Server/DB Bottleneck | Underlying Blockchain Throughput |

Frequently Asked Questions
Get clear answers on our process, security, and timelines for implementing blockchain-based identity and payment solutions for IoT devices.
We implement a multi-layered security architecture. Each device receives a unique, non-transferable on-chain identity (typically an NFT or SBT) anchored to its hardware root of trust. Private keys are generated and stored in secure enclaves (like TPM or HSM modules). All authentication logic is executed via audited smart contracts on EVM-compatible chains, ensuring tamper-proof verification. Our standard deployment includes a comprehensive security audit by a third-party firm.
