South Korean Mobile Telecom Giant Launches 2,500 Txns/s Commercial Blockchain

KT Corp may only be the second-biggest mobile carrier in South Korea, but the telecommunications firm is reportedly the first in the world to launch a blockchain-based commercial network.

According to The Korea Herald, KT Corp’s blockchain network will initially have the capacity to handle 2,500 transactions per second. Before the end of 2018, however, the capacity will have been quadrupled. By the end of next year, KT Corp intends to have increased the number of transactions per second to 100,000, according to the head of Blockchain Center at the KT Institute of Convergence Technology, Seo Young-il.

However must be noted blockchain does not mean decentralized. Blockchain can be thinked about as a slower more expensive but more securer version of a database. This extra expensive is passed along nodes,miners and users which all contribute to decentralised the system. What this commercial blockchain is doing instead is making a database that anyone can verify if they wanted to do, but since it commercial only the businesses using them verify…

Enhancing Security and Transparency

Per Young-il, KT’s blockchain-based commercial network will overcome the limitations of both public blockchains and private blockchains by making the existing network more transparent and secure.

“The whole point of applying blockchain to networks is to address security and transaction issues by making the current networks more secure and trusted,” Young-il told The Herald.

According to company officials, the mobile carrier developed its own engine which is capable of processing multiple blocks simultaneously. The wireless carrier will use its existing high-performance servers.

As you can see by their own comments validate my point. It will be centralised but more transparent.   

Global Presence

KT Corp is also planning on incorporating its blockchain solutions to other platforms such as the 5G network and artificial intelligence as the mobile carrier continues expanding in markets outside its home country. Currently, KT has a presence in Asia and Africa as well as parts of Europe and North America.

Additionally, KT is planning on rolling out a blockchain-enhanced data roaming service by partnering with network operators across the globe and this includes NTT Docomo of Japan.

South Korea’s second-largest mobile carrier has also launched a new internet technology which will be secure from hackers. This will be achieved by having users log onto the network using a blockchain ID rather than an IP address making additional identity verification unnecessary and thus preventing the risk of password and ID theft.

The blockchain is only as strong as it checkpoints and with so few of them, you just made the ability to easily check hacks more. 

Bright Future for Blockchain in South Korea

The development comes at a time when the blockchain market in the Asian country is expected to grow rapidly in the coming half a decade. According to South Korea’s Ministry of Science and ICT, the sector is expected to expand from approximately US$44 million in 2018 to a figure of approximately US$885 million in 2022. The government of South Korea has also become more increasingly accommodating of the blockchain sector and cryptocurrencies despite having previously taken a harsher stance.

However the government does not want to lose full control as such commercial blockchains as talked about in this post are the goal. Why? I believe so that they can control the business which in turn controls the chains. 

The country’s primary financial regulator, Financial Services Commission, announced that it was planning on establishing a department to be known as Financial Innovation Bureau which will be solely dedicated to nurturing the blockchain and fintech sector in South Korea. The Financial Innovation Bureau will exist temporarily for a period of two years.
