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 Elrond blockchain platform is designed to be a public development infrastructure that will be more secure, efficient, and scalable than other blockchain platforms. The Elrond blockchain is aimed at DApp developers and enterprises. Elrond will have a Prof of Stake consensus mechanism, and will include an Adaptive State Sharding feature that will allow multiple validators to process transactions in parallel.

Komodo is a blockchain building platform that is focused on developing anonymity and security focused solutions. Komodo's platform, which was originally a fork of ZCash, is powered by the KMD token, and enables users to send anonymous transactions. Komodo has a delayed Proof of Work consensus algorithm.
Komodo also operates Chainmakers and Chainzilla; which assist clients in creating their own blockchains, decentralized applications, and initial coin offerings. Komodo also provides services related to wallet integrations and blockchain security.
Komodo held the first ever decentralized ICO and pioneered the concept of a dICO. Their goal is to allow users to more easily build blockchain solutions and decentralized exchanges. They are developing a decentralized ICO (dICO) platform as well as a decentralized exchange platform called BarterDEX.
