How is blockchain revolutionizing the telephone sector?

Blockchain is a technology that allows information to be stored and transmitted in a secure, transparent and decentralized way. Its best-known application is cryptocurrencies, but it has many other possibilities in various fields, such as health, education, art or telephony.

In this article, we will explore how blockchain is transforming the telephony sector, offering innovative solutions to improve asset management, data security, quality of service and user experience.

What benefits does blockchain bring to telephony?

The telephone sector faces several challenges, such as competition, regulation, innovation, sustainability and customer satisfaction. Blockchain can help overcome these challenges, providing the following benefits:

Traceability: The blockchain allows the origin, state and destination of telephony assets, such as devices, SIM cards, antennas or networks, to be recorded and tracked in an immutable and verifiable way. This facilitates quality control, fraud prevention, resource optimization and cost reduction.
Security: The blockchain guarantees the integrity, confidentiality and availability of telephony data, such as calls, messages, contracts or invoices. This is achieved by encrypting, distributing and validating information between multiple nodes in the network, preventing manipulation, theft or loss of data.
Efficiency: Blockchain improves the efficiency of telephony processes, such as activation, portability, roaming or customer service. This is achieved through automation, simplification and standardization of operations, eliminating intermediaries, paperwork and human errors.
Innovation: Blockchain encourages innovation in the telephone sector, creating new business opportunities and added value for customers. This is due to the interoperability, flexibility and scalability of the technology, which allows the development of new services, products and business models based on the blockchain.

What examples are there of blockchain applications in telephony?

Currently, there are several examples of blockchain applications in the telephone sector, both nationally and internationally. Some of the most notable are:

Telefónica Tech:
It is a division of Telefónica that offers integrated technological solutions in cybersecurity, cloud, IoT, big data and blockchain. Telefónica Tech has different blockchain services so that companies can apply the technology in the most secure way, ensuring the authorship of the information that circulates, from where, how, when and who generates it. In this way, it ensures, through cryptography, that the recorded data cannot be modified1.
IBM Blockchain Platform:
It is an IBM platform that allows you to create, deploy and manage blockchain networks in any environment, whether public, private or hybrid. IBM Blockchain Platform has collaborated with Telefónica Tech to build a new solution that improves control of companies' assets throughout the supply chain, using hybrid cloud technologies2.
TrustOS:
It is a Telefónica platform that facilitates the integration of blockchain into any business process, without the need for technical knowledge. TrustOS offers different modules that solve common business problems, such as digital identity, traceability, tokenization or reputation. TrustOS has been used, for example, to create a blockchain network that allows Movistar+ customers to access exclusive and personalized content3.

Blockchain is a technology that is revolutionizing the telephone sector, providing benefits such as traceability, security, efficiency and innovation. The blockchain allows information to be recorded and transmitted in a secure, transparent and decentralized way, improving asset management, data security, service quality and user experience. In addition, there are several examples of blockchain applications in the telephone sector, both nationally and internationally, that demonstrate the potential and versatility of this technology.
