  Digital currencies can be categorized based on their underlying technology, such as blockchain-based currencies and non-blockchain-based currencies. Blockchain-based currencies, like Bitcoin and Ethereum, utilize a decentralized ledger system to record transactions and ensure security. They rely on consensus mechanisms, such as proof-of-work or proof-of-stake, to validate transactions. Non-blockchain-based currencies, on the other hand, may use alternative technologies, such as directed acyclic graphs (DAGs) or centralized databases, to achieve similar functionalities. Each category has its own strengths and weaknesses, and the choice of technology often depends on the specific requirements and goals of the digital currency project.
