VestChain is developing a smart contract platform that will have a double layer architecture. Their network is currently powered by the Ethereum based VEST token.

Wowbit, also known as Wowoo, is a NEO-based tokenization platform. Their smart contract enabled platform is based on their Smart Active Control (SAC) architecture, and is powered by the WWB 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.
