Zetacoin (ZET) is a decentralized cryptocurrency, launched in 2013 that is similar to Bitcoin in many ways. It was founded by a developer by the alias of Pawel Kuskowsky. Zetacoin is designed to facilitate the fast, secure, and low cost transfer of funds. Transactions are taken place on its own network layer, separated from Bitcoin’s conventional blockchain protocol. What makes Zetacoin unique? Zetacoin provides a unique feature in its block confirmation system. It utilizes a Proof-of-Stake (PoS) system, which encourages full nodes to actively process transactions. This is in contrast to Bitcoin, which supports a Proof-of-Work (PoW) system, where mining is used to validate the blocks. By incentivizing full nodes to process transactions, Zetacoin eliminates the need for mining and makes the network more secure and efficient. Where is it used? Zetacoin is not widely accepted as a form of payment and is not listed on any major exchanges. However, it can be used as a means of transferring funds quickly and securely, similar to Bitcoin. Where to buy/sell Zetacoin? The most popular exchange to buy/sell Zetacoin is CryptoBridge. This platform is an open source, community driven digital asset exchange. You can also find Zetacoin available for purchase on Crypto-Bridge, LiteBit.eu, and Crypto World. Overall, Zetacoin has much potential to change the digital currency industry. Its PoS system eliminates the need for mining, which makes it more efficient and secure. However, due to its relatively small user base, it is currently quite difficult to acquire and is not widely accepted. That said, it is definitely worth keeping an eye on as this could easily change in the near future.
