Telekom tests first inter-operator blockchain network

First inter-operator blockchain network

Deutsche Telekom, T-Mobile US, Telefonica, and Orange have created the first inter-operator blockchain network, together with the GSMA

- Providing a fully digital, resilient, simple and trusted solution for 
  concluding wholesale roaming discount agreements    
- Replaces the usual analogue and manual processes

  Telekom, T-Mobile US, Telefonica, Orange and the GSMA, are jointly testing a 
  production-ready solution based on blockchain technology. It allows operators 
  to easily generate and sign secure, inter-operator roaming discount 
  agreements.    The solution was initially designed by Deutsche Telekom 
  Laboratories (T-Labs) and Deutsche Telekom Global Carrier, the international 
  wholesale unit. However, plans are underway to open-source the code, so it can
  be freely used by the industry at large. It also drastically reduces the 
  complexity of the current process, which involves drafting, signing and 
  manually implementing inter-operator roaming discount agreements.    This 
  innovative development provides a new layer of trust, as the agreed-upon terms
  cannot be subsequently changed or tampered with. In addition, it allows a 
  holistic, analytic view of agreements, enabling further automation of the 
  roaming wholesale workflow in the future, for example settlement processes 
  between operators.    This is the first time operators are able to jointly 
  test blockchain as a solution that also incorporates a corresponding legal 
  framework, governance model, and integration into corporate IT 
  infrastructures. Hyperledger Fabric has been implemented for this project, 
  which is an open-source blockchain solution backed by the Linux foundation.   
  "Our new solution is scalable; therefore IoT devices and new emerging 
  business requirements can be easily accommodated in the future. Disputes and 
  financial losses will be minimized," says John Calian, Senior Vice President 
  and Head of T-Labs, Deutsche Telekom's innovation unit.    Rolf Nafziger, 
  Senior Vice President of Deutsche Telekom Global Carrier, adds, "The 
  inter-operator workflow in roaming has been basically unchanged for the last 
  20 years. In the near future however, new services like NB-IoT, LTE-M or VoLTE
  and other quality-based services will drastically increase the complexity of 
  inter-operator discount agreements and respective settlements. This 
  blockchain-based solution is the start of automating sections of our workflow.
  It will put us in a position to handle the additional complexity while 
  increasing overall efficiency."
