How Blockchain in Telecom Is Addressing Key Industry Challenges

Blockchain technology is opening up new areas of innovation for the Telecom industry. From 5G enablement to Identity-as-a-Service, blockchain technology is facilitating new business models, while solving age old challenges around data integrity and centralisation.

Data Security & Integrity

Communication Service Providers (CSPs) seeking to enhance data integrity and security are increasingly turning to blockchain solutions to track and secure data across various disparate systems. Decentralized networks paired with cryptographically secured data provides CSPs with a trusted source of immutable data that can be used throughout a company’s operations — from billing systems to identity management.

Automating Inefficient Operations

Automatic execution of transactions via smart contracts on the blockchain help provide a whole new level of efficiency for Telecoms providers. Laborious manual processes in areas such as identity verification, billing of services, and data roaming now benefit from automation and dynamic execution via blockchain technology. Overall, blockchain reduces the need for manual intervention and reduces the reliance on middle-men throughout a CSPs operations. Not only does this result in a better service for customers, but also leads to cost reduction through efficiency gains for the entire industry.

Blockchain Use Cases in Telecom

With benefits ranging from security to automation, blockchain for telecom is enhancing traditional operations and enabling new business models.



Digital ledger technology is enabling CSPs to create and share immutable digital identities for customers by storing data securely on the blockchian. These digital identities represent a largely untapped revenue stream for the telecom industry; identity-as-a-service.

Fraud Prevention

Fraud is a big problem for the telecom industry, costing billions of dollars every year. But, blockchain technology in telecom is helping providers to combat deception in two key areas, identity theft and roaming fraud. For data roaming fraud in particular, permissioned blockchains are enabling both the sharing of verifiable data between network operators, and the instantaneous settlement of roaming contracts, both of which are helping to reduce the risk of fraud.

5G Networks

When it comes to 5G Networks, blockchain technology is enabling providers to drive efficiency and provide a better service to customers in a number of areas. For example, the current Access Network Discovery and Selection Function System (responsible for selecting the most appropriate access network for a device), is a centralised system prone to delays and issues surrounding provisioning of networks. With a blockchain-based solution to ANDSF, smart contracts can allow for seamless provisioning between access networks for the device and end user. Plus the ability to enforce dynamic rules and contracts across provisioning networks — unlocking discounted rates or better connections.
