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.

QLC Chain, formerly known as QLink, is developing a Network-as-a-Service blokchain platform. It will allow them to provide decentralized network services and serve as a DApp development platform. The QLC network is currently built on NEO but will transition to their own blockchain in the future. The QLC Chain will have a hybrid consensus mechanism called Shannon consensus. It will combine elements of delegated Proof-of-Stake (dPoS) with a regulating mechanism that is designed to encourage participation by more nodes.
