Dash digital coin (formerly known as Darkcoin and XCoin) is an open source peer-to-peer cryptocurrency that aims to be the most user-friendly and most on-chain-scalable cryptocurrency in the world. On top of Bitcoin’s feature set, it currently offers instant transactions (InstantSend), private transactions (PrivateSend) and operates a self-governing and self-funding model that enables the Dash network to pay individuals and businesses to perform work that adds value to the network. Dash’s decentralized governance and budgeting system makes it a decentralized autonomous organization (DAO).

Unlike Bitcoin’s single-tier network, where all jobs on the network are performed by miners, Dash utilizes a two-tier network. Certain network functions, such as creating new blocks, are handled by the miners. The second tier of the Dash network consists of “masternodes” which perform PrivateSend, InstantSend, and governance functions.
Masternodes require 1000 DASH as collateral to prevent sybil attacks. That collateral can be spent at any time, but doing so removes the associated masternode from the network. Because masternodes provide vital network functions, the block reward is split between miners and masternodes, with each group earning 45% of the block reward. The remaining 10% of each block reward funds the “budget” or “treasury” system.
Dash has a few features that make it really unique:
Private Send – Dash allows you to send your funds privately by mixing it in between several other transactions, thus making it hard to identify any specific transaction. It uses a coin mixing service based on CoinJoin. This is an optional privacy feature which the user may want to use. But there is a limited cap of 1000 Dash for which you can send using this feature.
Instant Send – This service allows you to send your Dash transactions instantly (within 1.5 seconds). But Masternodes (see below) charges higher fees for processing such transactions. InstantSend also solves the double-spending problem. Note: InstantX was rebranded to InstantSend in 2016.
Masternodes – Unlike Bitcoin, where each note is equal, Dash has special privilege nodes called Masternodes. Anyone can form Masternodes by holding 1000 Dash as collateral. These special nodes perform PrivateSend and InstantSend functions, and earn a 45% block reward.
Dash has competitors, like Monero and PIVX. Dash is more flexible and ready to use, and it has a solid infrastructure. This sets Dash apart from the crowd and makes it a promising currency worthy of investment.
