Wanchain is a blockchain-based distributed superfinance marketplace. This is the definition that the developers whitepaper suggests. It is noteworthy that this loud name hides a really interesting filling. The Wanchain platform allows you to exchange digital assets between other blockchains. It uses the latest cryptographic theories to build a non-proprietary cross-chain and distributed ledger protocol that records both cross-chain and internal transactions.
Released in 2014, Groestlcoin (GRS) cryptocurrency enables private and fast transactions. It is the first coin that activated Lightning Network and SegWit. You can buy GRS for both crypto and fiat currencies (USD, EUR, GBP, KRW). This cryptocurrency is listed on multiple exchanges.
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.
