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
