Blockchain and the telecommunication industry

Blockchain and the telecommunication industry

By starke_kunst | art of crypto | 28 Nov 2019

I want to continue a series of articles about new areas where blockchain can be used. Also, I want to highlight some startups that are trying to implement blockchain solutions in those new areas.

Do not forget to check my previous articles “Blockchain and the digital advertising market” and “Blockchain and the decentralized video distribution”.

Today I want to talk about telecommunications. The first time I faced this type of using blockchain technology was when I saw the news in July 2019 that the consulting company KPMG began to cooperate with TOMIA, Microsoft and R3 in the development of the blockchain for telecommunications settlements.

The blockchain will help to solve the problems with operating data that arise with connecting 5G. A huge amount of data is generated daily, including metadata about when and where the call starts and ends, the terms of the contract with the user and payment information that must be authenticated by at least two parties if service operations occur. Most of the information will be verified using smart contracts developed by KPMG.


In the telecom industry, the blockchain can be applied to:

- digital identity

- data management (storage of various documents, insurance, airline tickets, etc.)

- roaming (exclude roaming fraud)

- 5G (selection of the fastest node for communication)

- Smart City (the concept of integrating several information and communication technologies and the Internet of things (IoT solutions) for managing city property)

- mobile trading

- M2M (Inter-machine interaction, Machine-to-Machine)

- IoT (secure P2P connection for IoT devices to create a cost-effective and self-managing system).

IBM roaming blockchain PoC solutions

IBM, together with Syniverse, has created a blockchain-based Unified Data Record (UDR) system that allows mobile operators to verify accounts under roaming agreements quickly. Thanks to the use of smart contracts, the blockchain system improves the efficiency of interaction between operators, ensures transparency of processes and simplifies dispute management in case of their occurrence. The feature has already been tested in Orange and TeleSystems (MTS).

Three months ago, the Enterprise Ethereum Alliance (EEA) published a collection of examples of the use of blockchain in telecommunications. The telecommunications activities group (SIG) includes T-Mobile, SK Telecom, KDDI, ConsenSys and others.


IBM, SoftBank and TBCASoft will launch a blockchain payment service for mobile operators Cross-Carrier Payment System (CCPS), to provide users with the opportunity to use their mobile phones for settlements with local enterprises abroad.


It is a decentralized global telecommunications platform that allows mobile operators and service providers to interact with each other directly. This solution is based on a private blockchain network, which provides autonomous regulation of fees for international roaming.


Any mobile operator can publish their prepaid tariff plans in the form of smart contracts in the BubbleTone blockchain. These offers will be visible to all other operators and their subscribers. When the subscriber activates the offer, a new smart contract is created, according to which the foreign operator directly receives data on the user's identity and payment. 

Thus, one of the very interesting areas for the development of the blockchain technology is telecommunications. This trend can be easily determined by the participants in such initiatives as IBM, SoftBank, Microsoft, Orange, T-Mobile, SK Telecom, etc.
