Truly Decentralized Gaming Platform
with Meta-Blockchain

We are the world’s first gaming platform built using meta-blockchain technology such as ETH, EOS, etc. We are building a next-generation gaming platform with a vision for a truly decentralized service focusing on three points: decentralized Identity, decentralized Ledger and decentralized CDN.


Develop a Decentralized Platform

We are developing a distributed version that combines the systems of the centralized and decentralized platforms for initial stable operations, but once P2P Seeder (Nodes) are secured, it will be changed to a fully decentralized dapp.
