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.
