Klaytn Coin is the native currency of the Klaytn blockchain. It was developed by the South Korean internet giant, Kakao and is operated by its subsidiary Ground X. Klaytn Coin is designed to power an enterprise-grade, service-centric platform that brings a user-friendly blockchain experience to its users. It has a hybrid architecture that combines elements of public and private blockchains. Klaytn uses an optimized version of the Istanbul Byzantine Fault Tolerant consensus algorithm. There are three types of nodes, CN (Consensus Node), PN (Proxy Node) and EN (Endpoint Node). CNs are managed by CCOs (Core Cell Operators) and are in charge of block generation. These blocks are verified by all nodes in the network.
It has partnerships with multiple prominent companies, including Binance, which serves on their governance council, and several large South Korean banks and technology companies. The company also plans to integrate with OpenSea's NFT marketplace to allow Klaytn-powered NFTs to be sold more easily.

Bytecent is developing a decentralized rewards network powered by blockchain. Bytecent allows merchants to create customer loyalty programs that are cross-site and cross-platform compatible. Consumers are not restricted to using their rewards with just one merchant, and can redeem them anywhere Bytecent is accepted. In addition to secure transactions and portability, Bytecent never expire and there are no limitations on how many Bytecent you can accumulate or spend. BYC can be converted to Bitcoin, cash, and gift cards. Bytecent uses a variation of Proof-of-Work (PoW) for consensus that requires miners to manually attend to their computers and is called Proof-of-Miner (PoM). It's designed to prevent the use of advanced and autonomous mining hardware. Avanquest Software, a leading developer of consumer software, has implemented Bytecent for their rewards program.
