PugCoin is a digital form of currency that allows people to make secure transactions online without the need for intermediaries like banks or governments. It uses encryption techniques to verify and record transactions and control the creation of new units. The main function of PugCoin is to provide a decentralized and secure way to transfer value between individuals or entities. Unlike traditional currencies, which are subject to central authority and can be manipulated by governments or financial institutions, cryptocurrency transactions are recorded on a public ledger and verified by a network of computers around the world.
