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.

CyberMiles is developing a decentralized ecosystem for e-commerce. Their blockchain platform will provide users a library of e-commerce focused smart contracts to develop DApps and will facilitate decentralized settlements between parties.
The Cybermiles blockchain will be optimized specifically for e-commerce exchanges and will maintain records of users' identities, credit histories, and reputation scores. Users will be able to enter into smart business contracts without human intervention.
The CMT token will power the CyberMiles e-commerce network

Ubiq is an Ethereum fork that aims to create a more stable smart contract platform for building DApps. Ubiq's protocol currently uses a Proof-of-Work (PoW) consensus mechanism, but will switch to Proof-of-Stake in 2019. The network is powered by the UBQ coin.
Ubiq's goal is to create a reliable and stable platform for developing DApps by modifying Ethereum's code base with important changes that will make it more secure and reduce instability. Consensus is based on their Flux Difficulty Algorithm, which is designed to constantly adjust the hash rate to protect against network attacks.
