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.

Nethereum is an open source .NET integration library for Ethereum. It is designed to help developers easily integrate the Ethereum blockchain into their .NET applications. It consists of modular libraries for features that are covered are writing smart contracts, cryptographic wallets, DApps, and managing blockchain data.

QLC Chain, formerly known as QLink, is developing a Network-as-a-Service blokchain platform. It will allow them to provide decentralized network services and serve as a DApp development platform. The QLC network is currently built on NEO but will transition to their own blockchain in the future. The QLC Chain will have a hybrid consensus mechanism called Shannon consensus. It will combine elements of delegated Proof-of-Stake (dPoS) with a regulating mechanism that is designed to encourage participation by more nodes.
