EOSeoul is an EOS block producer ​ candidate. [1] ​ Their team consists of NEOPLY and NEOWIZ, a leading online game company in Korea with more than 1,000 employees (including subsidiaries), and is a listed company on the Korean stock exchange with an annual revenue of approximately $200 million. [2] [3]

One of the main logos of EOSeoul.

NEOPLY is Korea`s first start-up accelerator set up in 2008 by NEOWIZ.

They have been developing and managing PC online & mobile games on a global scale and has been one of the leaders in this field in Korea for the past 20 years. [4]

NEOWIZ’ business has transformed and expanded over the years, closely following the history of the internet and the development of the industry, constantly searching for opportunities that rise in this space. They believe that the next big thing would be the blockchain protocol which would bring a new paradigm to this era. [5]

Image of the location of the servers that EOSSeoul will be a part of.

Users on the internet can copy and own data without incurring any cost. This openness was what allowed internet to explode and expand. However, this meant that the creator/owner of the data was not properly rewarded as he/she was entitled to. [6]


Blockchain protocol recognizes the ownership of data. The ownership belongs to the user who contributed or created the data, and reward is given to those who positively contribute to the ecosystem and thus providing incentive for them to continue to do so. [7]

However, there is still a lot of problems to be solved. The whole blockchain ecosystem needs to be more accessible to the wider public and developers need to contribute more useful services to this ecosystem and thus create a positive cycle. At the same time, the block producers need to provide a reliable network infrastructure. They believe that EOS software could be the closest solution to the issues that we are facing. Therefore, they would like to participate in the innovation of the EOS ecosystem. [8]

Their block production servers will be located in Tokyo ​ and Singapore ​. [9]
