Harmony is developing an open consensus blockchain platform. Harmony's sharding-based consensus mechanism is designed to scale as the number of nodes increases in the network. Harmony aims to tackle issues related to scalability by optimizing across multiple layers in a way that will enable parallel transaction processing with reduced latency. Harmony is currently powered by the ONE token, which is built on the Binance blockchain.

Lisk is a blockchain-based platform that allows developers to build and publish their own applications. Lisk uses sidechain development kits, that are written in Javascript, to enable users to create their own blockchain applications according to their needs. Each decentralized App runs on its own sidechain that can be customized, and is connected to the Lisk blockchain, which has a Delegated Proof-of-Stake (dPoS) consensus mechanism. The Lisk network is powered by the LSK coin.

RSK is an open source smart contract platform that is secured by the Bitcoin network. RSK is designed to add value and increase the functionality of the Bitcoin ecosystem by providing smart contracts that are compatible with the network's code and can be written in Solidity. RSK smart contracts are powered by the SmartBitcoin (RBTC) which is linked to Bitcoin. (1 RBTC=1 BTC)
RSK developed the RIF Token which is intended to enable users to access a range of DApps within their ecosystem. In September 2019, RSK purchased the Spanish social media platform Taringa with the goal of using the RIF token as an incentive to encourage users to share content.
