ThunderCore is a Proof of Stake blockchain that is powered by the native Thunder Token. ThunderCore is compatible with Ethereum and is designed to have fast confirmation times. Transactions are verified by consensus nodes that complete a round of voting to confirm transactions in under one second. The network's compatibility with Ethereum is intended to allow developers to easily migrate DApps to the platform.

Mainframe is creating a blockchain development platform for decentralized applications. Their marketing materials place a strong emphasis on encryption, privacy, and interoperability. Onyx, a decentralized workplace messaging tool, is the first application to be built on the Mainframe network.
Mainframe is powered by the MFT token.

QuarkChain is building a blockchain with a focus on speed and scalability. They hope to significantly improve transaction times and reduce fees with an architecture that will rely on a two-layered blockchain and elastic sharding. QuarkChain uses a hybrid Proof-of-Work (PoW) consensus mechanism that is ASIC-resistant. Transactions are first confirmed on one blockchain layer, and then on the second. The network will be powered by the QKC coin.
