PIVX (Private Instant Verified Transaction) was launched in February 2016 as a fork of DASH, primarily due to philosophical differences. While Dash is pushing for mass adoption of cryptocurrency as its primary goal, the PIVX team wanted to work further towards making transactions more private. The two coins are still very similar from a technical perspective. PIVX has a 60 second block time compared to Dash’s 2.5 minutes, but both also offer “instant” transactions for a nominal fee.
Bitcoin revolutionized the world of cryptocurrency when it introduced a decentralized blockchain, but after its release many developers thought of ways it could be improved. While some of these developers ended up working on Bitcoin itself, Evan Duffield decided to go his own way when he created Dash. His goals with Dash were to increase anonymity, make a more user-friendly cryptocurrency, and make sure the system could scale into the future.
