Built on blockchain.
Secured by NFC.
The Xordex blockchain engine and NTAG424 DNA NFC chips work together to create an authentication infrastructure that is cryptographically secure, independently verifiable, and impossible to counterfeit.
Counterfeiting is a $1.7 trillion problem.

Composer
Orchestrates data. Aggregates verified transactions, composes blocks, and manages cross-node synchronization.
Flexible consensus mechanisms.
Proof of Authority
Default. Trusted validators, instant finality, zero gas fees.
DEFAULTProof of Stake
Token-staked validation with economic security guarantees.
Proof of Work
Computational proof for maximum decentralization.
Delegated PoS
Elected delegates for high throughput with governance.
Enterprise-grade security at every layer.
ECDSA Encryption
Elliptic curve digital signatures for transaction authentication
SHA-512 Hashing
Cryptographic hashing for data integrity and tamper detection
Access Control
Granular role-based permissions across all node operations
Block Explorer
Real-time transaction visibility and independent verification
NTAG213 vs NTAG424 DNA β choose your security level.
| Feature | NTAG213/215 | NTAG424 DNA |
|---|---|---|
| Security Level | Basic | Bank-grade |
| Key Storage | On-tag (password) | Secure element (isolated) |
| Authentication | Static UID | Dynamic CMAC |
| Clone Resistance | Low | Virtually impossible |
| Encryption | NXP password | AES-128 + CMAC |
| Use Case | Basic tracking, low-value goods | High-value, regulated products |
Three phases. Zero doubt.
Encoding
Secure identity creation
CSPRNG generates unique cryptographic key per tag
Hardware-backed encryption with audit trails on backend
UID (basic) or CMAC (advanced) with SHA-512 hash integrity
Scanning
Consumer verification
Smartphone detects tag within 1β3 cm, no app needed
Tag transmits URL with unique identifier to verification endpoint
Dynamic page with authentication result + product data
Verification
Blockchain-anchored proof
UID matched or CMAC verified via challenge-response against blockchain
Authentic/invalid status with product origin, certifications, metadata
Verification hash anchored on-chain with block explorer link
Plug-and-play service ecosystem.
Extend your blockchain network with modular services β authentication, KYC, supply chain tracking, loyalty programs, and more.
