Distributed Ledger Roaming

Decentralized Multi-Carrier Settlement

Decentralized ledger technology replacing centralized international roaming clearinghouses with real-time, zero-fee cryptographic settlement.

Technical Explanation

Traditional international mobile roaming relies on expensive third-party financial clearinghouses that charge high fees and take days to reconcile call detail records (CDRs). Distributed Ledger Roaming establishes a permissioned consortium blockchain among global telecom operators. When a subscriber makes a call or streams data in a foreign country, smart contracts settle the roaming charge between carriers in milliseconds, eliminating intermediary clearing fees entirely.

Key Functions

  • Decentralized consortium blockchain uniting international telecom operators
  • Instantaneous peer-to-peer financial settlement for international roaming data and calls
  • Eliminating costly third-party roaming clearinghouses and currency exchange risks
  • Cryptographically signed Call Detail Records (CDRs) preventing roaming billing disputes
  • Native integration with GSMA Wholesale Settlement standards and 6G SEPP proxies
