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.

The Interplanetary File System (IPFS) is a decentralized network protocol for sharing hypermedia in a distributed file system. IPFS can be used to link blockchain transactions This effectively timestamps and secures the content, without having to put the data on the chain itself. Filecoin, an IPFS-based decentralized storage cloud, is closely related with the IPFS protocol, and provides the incentive system.

Penta is developing a blockchain platform that DApps can be built on. It will have a Dynamic Stake Consensus (DSC) algorithm to confirm transactions. The Penta network is currently powered by the Ethereum-based PNT token.
