Harmony is developing an open consensus blockchain platform. Harmony's sharding-based consensus mechanism is designed to scale as the number of nodes increases in the network. Harmony aims to tackle issues related to scalability by optimizing across multiple layers in a way that will enable parallel transaction processing with reduced latency. Harmony is currently powered by the ONE token, which is built on the Binance blockchain.

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.

QuarkChain is building a blockchain with a focus on speed and scalability. They hope to significantly improve transaction times and reduce fees with an architecture that will rely on a two-layered blockchain and elastic sharding. QuarkChain uses a hybrid Proof-of-Work (PoW) consensus mechanism that is ASIC-resistant. Transactions are first confirmed on one blockchain layer, and then on the second. The network will be powered by the QKC coin.
