The First Public Chain with Telecom Service Capability


Understand QLC Chain as the first public chain that is embedded with telecom service capabilities

QLC Chain (previously “Qlink” https://qlcchain.org/ ), the public Blockchain for decentralized Network-as-a-Service continues to strengthen its public chain development with the advent of 5G. It is the world’s first infrastructure level public chain with embedded telecom service capabilities, including billing, security and the trusted Cross-Carrier Payment Systems (CCPS). Other than billing and clearance, QLC will also develop user identity authentication and authorization solutions for network access, as well as IPV6 P2P addressing functions, in the future. They are the essential parts of the QLC Chain’s mission which is to create a secure and trusted environment for telecom service providers at the same time to narrow down the digital divide by leveraging Distributed Ledger Technology, to deliver high-quality telecom service to the 4 billion unconnected people in the remote area.

In terms of technology structure, QLC Chain adopts the innovative multidimensional Block Lattice structure with programmed smart contracts on top of it, which is an industrial high-performance structure. The Directed Acyclic Graph structured architecture has high scalability with a transaction per second(TPS) number as high as 7,000. With QLC chain as the infrastructure, each operator around the world can issue their own token to enhance their competitiveness, increase credibility and at the same time lower the operating cost.

The testnet with explorer and wallet, recognized and praised by community members, peers and rating institutions, has already been online since October, 2018. The next milestone for the public chain development team would be delivering the global SMS billing and clearance system that has the capability of facilitating 20 billion transactions per year, by the end of March, 2019.

In A2P SMS industry, the clearance market is not as standardized and transparent as the financial industry. The trustworthiness of agreements made between service providers, telcos, and other related parties have been the core pain points of the global SMS business model. With the first deliverable of QLC Chain, the public ledger will smoothen the inter-carrier clearance process and provide a trusted layer for people’s everyday use of telecom services. In return, the infrastructure will benefit every consumer and smartphone user.

New Hire

With great pleasure QLC announces the addition of Wen Yuangui in the team as Senior Public Chain Developer. Wen will lead the development of Block Lattice based public chain for telecom services. Wen Yuangui has over 10 years experience with Huawei Technologies, one of the largest telecommunication equipment vendors in the world. Wen was responsible for developing various routing protocols, during which time earned multiple patents. In 2018, Wen devoted in blockchain technologies industry, successfully developed a blockchain big data collection system from on-chains, mainstream exchanges and news platforms. We believe that Wen will bring ample relevant knowledge and experience to the project.

“It is an exciting opportunity to join QLC Chain. I believe that, what QLC Chain is working on would be the next step of telecommunication industry evolution, advancing operators’ technology and business model at the same time enhancing the next generation telecom service users’ experience. I am honored to be one of the team members and feel privileged having the pertinent experience to contribute”, says Wen Yuangui.

QLC Reviews

Cointastic who is also a community member of QLC did thorough research and wrote a review article. Read the full article here:

Mark van Rijmenam who is the Author “Blockchain: Transforming Your Business and Our World” & “Think Bigger”, and influencer on Blockchain & Big data wrote the article 3 Ways How Blockchain Could Disrupt the Telecom Industry, and mentioned QLC as one of the practitioners.

About QLC Chain
QLC Chain is the next generation public Blockchain for decentralized Network-as-a-Service(NaaS). The QLC Chain and supporting ecosystem will enable any individual, business or organization to leverage their network resources to instantly become a service provider or network operator. The mission is to bring people online through a simpler, more pleasant, and more secure way with full transparency.

It deploys a multidimensional Block Lattice architecture and uses virtual machines (VM) to manage and support integrated Smart Contract functionality. Additionally, QLC Chain utilizes dual consensus: Delegated Proof of Stake (DPoS) and Shannon Consensus, which is a novel consensus developed by the QLC Chain team. Through the use of this dual consensus protocol and multidimensional Block Lattice architecture, QLC Chain is able to perform a high number of transactions per second (TPS), provide massive scalability and an inherently decentralized environment for NaaS related applications (dApp).
