We would like to describe MARBLEX in the perspective of technology applied to the MBX token. The MBX token is a Klaytn Compatible Token (“KCT”) based on Klaytn blockchain. The Klaytn technology is designed to provide high performance extensively and thus features high transaction processing. At the same time, KCT is based on the Istanbul BFT consensus algorithm and is a mainnet that assures reliability and transparency. Based on the strength of KCT, MBX can also process the high transaction of game content quickly and provide reliability to users under transparent operation/management.
