NEM (New Economy Movement) is a blockchain-based platform for operation of mission-critical transactions for businesses. The platform has its own blockchain and a native token called XEM. NEM appeared on the market in 2015. Currently, it is one of the most successful blockchain projects hailing from Japan.
SmartMesh (SMT) ERC-20 token is used as a means of payment within the SmartMesh ecosystem, as well as the reward coin to node contributors and users. It is listed on a few exchanges and trading against BTC, ETH and USDT.
Ark (ARK) is the native token of the blockchain-based Ark platform. The platform itself provides the instruments that enable users to develop and customize other blockchains. The blockchains can be managed through the TypeScript programming language. Moreover, these blockchains can be connected to each other via the functionality of Ark. The Ark framework can be used to execute peer-to-peer operations, manage the data on a distributed ledger, access API solutions, etc. The Generic Transaction Interface can be used to customize the types of transactions and entire blockchains. Unlike Solidity, TypeScript is much easier for the general public which makes Ark more user-friendly.
