While most people will have probably heard about Vertcoin, not everyone is aware they have recently changed their mining algorithm. Vertcoin has always prided itself on being an ASIC-resistant digital currency, and therefore launched with the Scrypt-N algorithm, which reduces mining efficiency over time.
As digital currencies need to keep evolving over time in order to stay relevant and ahead of the curve, the VTC developers felt a change in mining algorithm was in order. And not just to a regular mining algorithm we have all heard about, but they chose for the Lyra2RE algorithm. Lyra2RE is a new Proof-of-Work algorithm for an ASIC-free future.
