YAcCoin was developed and released in 2013. It was the first digital currency to introduce the Scrypt-n algorithm. YAcCoin is a hybrid PoW and PoS (Proof-of-work and Proof-of-stake) system with a minimal transaction fee of 0.01 YAC. The coin is still in its inflationary-deflationary economic model phase – the block rewards regarding the Proof-of-work mining are equivalent to the amounts of the used computer power. The Proof-of-stake is set at 5 percent per annum. The Fixed transaction fees of the coin are used as a tool of supply depending on the applied velocity.
