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.

CanonChain is developing an underlying blockchain protocol based on Fog networking and a Proof-of-Participation (PoP) consensus mechanism. Their network is designed to provide incentives for contributing computing resources on fragmented networks, and is powered by the Ethereum-based CZR token, known as Xuanchi.

Aergo is developing an SQL based smart contract platform that will allow developers to more easily share data and create DApps. Their platform will combine elements of public and private blockchain architectures and will have a hybrid BFT/dPoS consensus mechanism. The ERGO Hub will serve as a blockchain hosting service that will allow users to test and deploy their own blockchains. Their network is currently powered by the Etherem-based AERGO token.
