What is Dash?
Dash (DASH) is a blockchain-based peer-to-peer cryptocurrency that was forked out of Bitcoin to offer faster transactions to users than Bitcoin could deliver. Dash is a blend word for digital cash.
Dash was launched in January 2014 as Xcoin, and quickly changed its name to Darkcoin. In March 2015, Darkcoin was rebranded as Dash.2 Dash was created as a fork of Bitcoin, which means it duplicated Bitcoin’s existent code and made it better by addressing the issues users faced with Bitcoin.
So apparent flaws and weaknesses in Bitcoin are absent in Dash, making both digital coins substantially different in terms of efficiency. As an alternative to Bitcoin, Dash provides a faster and more anonymous service to its users.
One of the setbacks of using Bitcoin is the slow rate at which funds are transferred, confirmed, and visible in a recipient’s account. It could take minutes or even hours for a transaction to be confirmed and finalized using the Bitcoin system. With Dash, however, it takes seconds to confirm a transaction.
While a number of other cryptocurrencies also offer instantaneous confirmed transactions like Dash, not all of them lock down these transactions once they are made. Consider a buyer who purchases goods from a seller and sends their payment. If the system confirms the payment but does not lock the amount down, the buyer could make another purchase using the same funds that should have been restricted in the first place.
In the crypto world, this phenomenon is called the double-spending issue. The InstantSend (previously called InstantX) feature available to Dash users solves the double-spending issue by barring the amount of money that is sent without having to wait for a block confirmation to consider the transaction confirmed.
