Ark is secure blockchain technology platform that aims to build an entire ecosystem of linked blockchains. This spiderweb-like network will have many use cases, thanks to Ark’s scalable and flexible structure. Its blockchain technologies makes its easy for developers to build their own blockchains and link them with the other blockchains in the Ark ecosystem through SmartBridges. Some of its already existing parts are a physical card system, a hypermedia protocol platform, and a privacy system. It has a Delegated Proof of Stake consensus and a Byzantine fault tolerance system in place to further secure the ecosystem.
Ark (ARK) is the underlying token of the main blockchain of the Ark ecosystem which can be used to give block rewards and can also be sent peer-to-peer.
