TrueChain is developing a secure and scalable blockchain platform with a strong developer community. TrueChain hopes to improve upon current platforms with a hybrid consensus protocol called Minerva. This hybrid model will combine a consensus mechanism based on Practical Byzantine Fault Tolerance (pBFT) with a FruitChain-based Proof-of-Work protocol. Fruitchain is designed to minimize the incentives of mining pools by decreasing the variance of mining rewards; making the network more decentralized.
TrueChain's architecture also hopes to improve transaction times and reduce fees, by including a sharding mechanism that is locked to Gas fees. The first use cases for their platform will be digital advertising solutions.
The company is backed by several large Chinese blockchain companies, including ZB.com; one of the largest cryptocurrency exchanges. digital advertising industry

Infura is a DApp infrastructure provider that was created by ConsenSys and gives developers the tools to securely access Ethereum and IPFS. Their API enables users to set up Ethereum Nodes, and then install, configure, and maintain the Ethereum infrastructure more easily, and at lower cost. Infura was originally created by ConsenSys.

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.
