Instant crypto transactions with Dash InstantSend

InstantSend transactions are locked and confirmed in just 1 second — vs. 60 minutes with Bitcoin. Pioneered by Dash and often copied by other coins.

Double-spend is a first generation cryptocurrency problem.

Double spending means spending the same money twice. If Bob buys a t-shirt from Ted for 1 DASH, then tries to buy one from John using the same 1 DASH, only one of these transactions are going to confirm. Both Ted and John have to wait for confirmations in order to give the t-shirt to Bob.

First generation cryptocurrencies must wait for a certain period for enough blocks to pass to ensure that a transaction is both irreversible and not an attempt to double-spend. This process is time-consuming and may take from 10 minutes to 1 hour. Other cryptocurrencies achieve faster confirmation by centralizing authority, defeating the whole purpose.

How Dash solved the double-spend problem.

Our decentralized masternode network locks InstantSend transaction and ensures it will not be double-spent. InstantSend allows Dash to be used in point-of-sale without relying on a centralized authority. Bitcoin takes 10 minutes to have 1 confirmation — sometimes more — while InstantSend transactions have the equivalent of 24 confirmations on the Dash blockchain in 1 second.

Dash is 3,600x faster than Bitcoin.
