EvenCoin is a self-mining smart contract platform that is built on the Ethereum blockchain. EvenCoin is mined in parallel to even numbers of Ethereum blocks. The team behind EvenCoin are developing several decentralized projects that will use the self-mining protocol, including an exchange and a travel booking platform.

Fantom is developing a smart contract platform based on a directed acyclic graph (DAG). They hope to address the scalability issues of current decentralized platforms. Instead of a blockchain, Fantom's Lachesis Protocol uses a directed acyclic graph to confirm transactions asynchronously. This transaction history is immutable and cannot be modified. The platform's Opera Chain will consist of three layers: an application Layer, Opera Ware Layer, and Opera Core Layer. Fanotm issued an Ethereum-based token in 2018.

BitNew Chain is building a development platform for commercial DApps. BitNew Chain aims to make it easier to develop large scale DApps that can be used with hardware. It will be based on a two-tier decentralized blockchain network with standard physical masternodes, resource segregation, a decentralized computing subsystem（BTN-DC）, and decentralized storage subsystem（BTN-FS). Consensus will be achieved through a hybrid mining process that will combine Proof-of-Stake (PoS) with Proof of Masternode. The network is powered by the BTN coin.
