What is PotCoin and how does it work?

Could you elaborate on PotCoin, its origin, and the mechanisms that power its operations? As a cryptocurrency specifically designed for the cannabis industry, how does it differentiate itself from other digital currencies? Is there a particular blockchain technology that PotCoin employs, or does it utilize a unique consensus mechanism? Furthermore, how does the ecosystem work in terms of transactions, exchanges, and wallets? What are some of the challenges PotCoin faces, and how is it overcoming these barriers to wider adoption? I'm particularly interested in how PotCoin aims to revolutionize the cannabis industry through its decentralized and secure financial solutions.
