CBSG aims to provide telecom members and their customers various services such as secured global digital payments, clearing and settlement, personal authentication, IoT applications and other services using blockchain technology.

The Consortium is also announcing the creation of an additional blockchain working group that will focus on global remittance services. Blockchain technology is well suited for these types of transactions; streamlining processes to better serve consumers. The blockchain platform and solutions proposed by the CBSG Consortium are specifically designed for telecom carriers and will help them create and extend their services beyond traditional markets and borders.

Dominic P. Arena, Group Chief Strategy and Marketing Officer, Axiata Group, said, “As we transform into a New Generation Digital Champion, Blockchain has been identified as a digital platform opportunity which, by design, is extremely well suited to the global telecom operator ecosystem of trusted, connected and distributed parties. We look forward to working with our operator peers to develop the world's most secure and fit-for-purpose Blockchain-as-a-Service (BaaS) infrastructure, upon which we will build the next generation of digital services for our Consumer and Enterprise & Government customers.”

PLDT FVP and Head of International and Carrier Business and PLDT Global Corp. President Katrina Luna-Abelarde said, “The inter-carrier blockchain technology will definitely bring enormous benefits to PLDT's overseas customers whom we have been serving for over 15 years. With the transformation of their lifestyles in the digital era, they require the streamlined solutions proposed by the CBSG Consortium, such as global remittance services, among others. We seek to empower our global customers with CBSG's new platforms and solutions.”

Faizal Rochmad Djoemadi, CEO of Telin said, “The core attributes of blockchains, which is shared ledger, can ensure trust and safe transactions between all participants which potentially can generate new services especially in the digital asset transactions area, mobile transactions and international remittance. We believe deploying blockchain as a service in Telin's extensive global infrastructure will enable our customer's digital business and solution. For Telin, joining the CBSG Consortium will provide a platform to collaborate among global carriers to explore and quickly deploy the service globally.”

Kaan Terzioglu, CEO of Turkcell said, “By transporting valuable digital assets over mobile networks in a secure and transparent framework, blockchains can speed the growth of the digital economy and help us to deliver new services for our customers. We must look beyond simply extending the connectivity of existing telecom infrastructure. As mobile carriers, we are well positioned to offer a ‘blockchain-as-a-service’ ecosystem and we must use this advantage. Therefore, we are looking forward to sharing our experiences with CBSG to discover together the possibilities to monetize on this next generation global cross-carrier blockchain platform. Being a part of this leading telecom blockchain consortium will help us to enhance our services and improve customer experience on our digital platforms.”

“Blockchain is an emerging technology that is changing the way of doing business in every industry. With CBSG global cross-carrier blockchain platform and ecosystem, we are looking forward to not only bring various services such as top-up, roaming wallet, secured clearing and settlement, personal authentication, IoT applications, etc… for our customers but also enhancing their experience in the digital era” said Mr. Doan Dai Phong, Director of Viettel International Business.

Scott Gegenheimer, Zain Group CEO-Operations said, “Blockchain is an important evolving technology, and collaboration is necessary in order to harness the applications and use cases it delivers. As Zain transforms into a digital lifestyle operator, it is important for us to be in the company of other progressive network operators within the Carrier Blockchain Study Group, and together I believe our work can achieve truly remarkable results leveraging blockchain technology across markets and applications.”

Daichi Nozaki, Vice President, Head of Global Business Division, Enterprise Business Unit of SoftBank said, “I am happy to see that other great carriers recognize the significant opportunity in a blockchain platform specifically designed for them — and the inherent advantage a consortium blockchain has over private and public blockchains. SoftBank is continuously building innovative services for its customers who have lives that extend beyond geographic borders. Being able to leverage the new CBSG cross-carrier working groups opens up exciting possibilities to extend our services to match their lives.”

Ling Wu, Founder and CEO of TBCASoft said, “The CBSG Consortium has been growing very fast since it was founded in September 2017. We have accomplished a lot in inter-carrier blockchain business innovation with existing CBSG members. TBCASoft is the leading cross-carrier blockchain platform and solution provider.
