Energi Coin is a Proof-of-Stake (PoS) cryptocurrency that combines smart contracts, decentralized governance, and a self-funding treasury. Energi was founded by Tommy World Power, with the goal of creating a more sustainable cryptocurrency that had the potential for mass adoption. Energi Coin's funding model is a built-in to the protocol and fuels the growth of the project. Aa portion of freshly-mined coins is assigned to the Treasury. The treasury allows the project to fund not only development, but also support, operations, and marketing. The founder, Tommy World Power personally funded the initial development of the project. Energi is currently shifting to a Solidity-based smart contract platform that will combine all of Ethereum’s existing capabilities with Energi’s unique governance and treasury model.

QChi is an Ethereum-based token with no clear benefits. Their marketing materials do not provide any specific information about their roadmap or what advantages it offers compared to other cryptocurrencies.

DigiByte is a a blockchain platform that places an emphasis on security and block speed. DigiByte has one of the fastest block speeds of any public blockchain and uses an innovative consensus protocol with 5 mining algorithms. This prevents mining centralization and also minimizes the chances of security breaches. DigiByte transactions are limited in size and scope to increase speed, efficiency, and throughput.
DigiByte hopes that these innovations will provide the ideal blockchain infrastructure for a range of applications within the IoT and AI fields, that require a high degree of security and fast block speeds.
