Cryptocurrency and blockchain are closely related technologies, but there are key differences between them. Cryptocurrency is a decentralized digital currency that is not regulated by central banks. Blockchain, the technology underlying cryptocurrency, is a decentralized digital ledger used to record and verify transactions. Characteristics of cryptocurrencies include anonymity, decentralization, and limited issuance. The characteristics of blockchain include distribution, immutability and transparency. They have wide applications in areas such as digital payments, supply chain management, and financial services. However, cryptocurrencies face volatility and regulatory risks, while blockchain faces scalability and privacy challenges.
