Colt Technology Services and PCCW Global, the international operating division of HKT, Hong Kong’s premier telecommunications service provider, announced that have further progressed their blockchain Proof of Concept (PoC).

Additional members of the ITW Global Leaders’ Forum (GLF) are also getting involved in the initiative. Fellow GLF members now getting involved include; BT, HGC Global Communications, Telefonica and Telstra.

Colt and PCCW Global, in conjunction with blockchain start up Clear, revealed in March that the businesses had undertaken a trial that demonstrated how the inter-carrier settlement of wholesale international services, could be automated through the use of blockchain. By using blockchain technology, the PoC was able to reduce this labour intensive process from hours to minutes.

The initial PoC used historical data as a test of the technology and its use case for the sector. Now, the parties have taken the trial a step further by ingesting actual live data feeds into the ledger, enabling traffic to be automatically verified and settled between carriers.

While the original two carriers are now using live data to verify and settle traffic, other members of the GLF have also seized the opportunity to get involved in the initiative, with the aim being to soon expand the bilateral testing between Colt and PCCW Global to encompass a multilateral series of relationships among the wholesale telecommunications industry as a whole.

Carl Grivner, CEO, Colt
We were optimistic by the success of the initial trial, but utilising live data was an important next step to prove the use case for blockchain technology in our industry. 

Marc Halbfinger, CEO, PCCW Global and the Chairman of the GLF
A lot of the conversations at the GLF have been around how innovative technologies such as blockchain can be used to improve the overall efficiency of the industry, and with the PoC expanding to include more carriers, it is clear that the industry is seeing the benefit of becoming further aligned.
