Dash is a digital currency that can be operated online. Users can use Dash to make secure online instant payments. Merchants can add an open source payment platform built by millions of users around the world to the store. The core of Dash is composed of a unique incentive P2P network. Miners are rewarded for maintaining the security of the blockchain; the master node holders are rewarded for users to verify transactions, store data, and provide multiple services. The master node represents a new level of network. They can form a highly secure cluster-arbitration chain, providing a variety of decentralized services, such as instant transactions, anonymity, decentralized management, etc. At the same time, it can also prevent low-cost network attacks. Thanks to Dash's reward mechanism, its network master nodes have grown to 4,100 since its issuance in 2014, which means that Dash P2P network has become one of the world's largest networks. More nodes mean higher security performance, Dash can provide round-the-clock digital currency services for more end users from all over the world.
