Abstract: Telephone calls can be validated using blockchains. In one example, a computing node can generate a distributed ledger indicating relationships between telephone numbers and unique identifiers assigned to the telephone numbers. The distributed ledger can be accessible to a telecommunication system for validating telephone calls.

Abstract: Telephone calls can be validated using blockchains. In one example, a telecommunication system can access a distributed ledger indicating relationships between telephone numbers and unique identifiers assigned to the telephone numbers. The telecommunication system can then verify a telephone call based on the relationships in the distributed ledger.
