NEO, formerly known as AntShares, is one of the leading smart contract enabled blockchain platforms that allows for the development of digital assets. Similar to Ethereum, NEO uses two different tokens: NEO and GAS, each of which have a specific purpose on the network. NEO tokens give holders a share in the ownership of the NEO blockchain, and when they are held in a compatible wallet, they are rewarded with GAS tokens. NEO has a Delegated Byzantine Fault Tolerance (dBFT) consensus algorithm that has uses some features of PoS, and is designed to be more scalable than other consensus mechanisms.

The UMA token is used to enable holders to participate in community governance issues and to help resolve contract disputes on the UMA platform. UMA is designed to be a decentralized financial contracts platform, and is an abbreviation of Universal Market Access. Their goal is to build the financial infrastructure that will make creating decentralized financial services easier. UMA provides a variety of smart contract templates as well as a decentralized oracle that can be used to validate payouts related to financial contracts.

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.
