APIS is developing a masternode mediation platform that will lower the barriers of entry for users wanting invest their coins on their own masternode of a network. A masternode is a type of node that has additional voting influence and block rewards, on a Proof-of-Stake network. Investors are able to place coins on a masternode and receive a stable interest from the block rewards; similar to interest that is given in a bank. APIS will allow users to invest in masternodes without having to deal with the technical requirements or stake a prohibitively large number of coins.
Their network is powered by the Ethereum-based APIS token.

Emercoin is a blockchain-based development platform. It has developed a range of easy-to-use dSDKs (Decentralized Software Development Kits) that can be used to more easily build DApps. This set of software development tools allow the creation of blockchain-based software and services.
Emercoin's dSDKs have been implemented in several innovative DApps and provide developers with solutions for a variety of functionalities. Some of the dSDK's that Emercoin offers are specifically geared for decentralized DNS, SSH, SSL, and DPO solutions.
Emercoin has a hybrid consensus mechanism that combines elements of Proof-of-Stake (PoS) with a Proof-of-Work (PoW) algorithm that is merge-mined with Bitcoin. The network is powered by the EMC coin.

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.
