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.

Algorand is a Boston based company that is developing a blockchain network with a Pure Proof of Stake (PPoS) consensus mechanism. Algorand's decentralized platform is designed to enable faster transaction times and remove some of the technical barriers of creating scalable DApps. Algorand was founded by Silvio Micali, a pioneer in the field of cryptography.

The Matic Network is a sidechain based scaling solution for public blockchains. Matic aims to allow developers to better scale their Ethereum DApps by using a version of Plasma, along with side chains that use a PoS consensus mechanism. Matic plans on supporting other blockchains as well in order to facilitate interoperability.
