Zetacoin (Symbol: ZET) is a SHA256-based digital currency with high-speed transactions and high-speed difficulty adjustment. Zetacoin (ZET) is a decentralized open-source digital currency cloned from bitcoin in 2013. Zetacoin is similar to bitcoin, but it employes newer technologies to advance the transfer speed; Zetacoins are usually confirmed within 30 seconds, making them ideal for swift, smaller, day-to-day exchanges. The second important feature is that Zetacoin is inflationary. The initial circulating supply of 160 million Zetacoins are increased with a further one million coins/year, making up for lost coins and maintaining the increasing demand for Zetacoin. Zetacoin was not pre-mined at launch and is therefore regarded as a fair-mined” digital currency.
