What is the essence of digital currency?

Digital currency is a decentralized digital asset that is traded and controlled through distributed ledger technology (such as blockchain). Its essential characteristics include anonymity, immutability, scarcity and programmability. Digital currencies are primarily used for online transactions and payments, but also extend into areas such as remittances, investments, and decentralized finance (DeFi).

The Essence of Digital Currency

Digital currency is a digital asset that is usually traded and controlled using cryptography technology. Unlike traditional currencies, digital currencies do not have a physical form but are stored in digital wallets or accounts.

Essential characteristics:

• Decentralization: Digital currencies do not rely on central banks or other financial institutions, but are managed through distributed ledger technology (such as blockchain).
• Anonymity: Many digital currencies offer anonymous transactions, allowing users to transfer money without revealing their identity.
• Immutability: Once a transaction on the blockchain is recorded, it cannot be tampered with or reversed.
• Scarcity: Some digital currencies, like Bitcoin, have a limited supply, giving them intrinsic value.
• Programmability: Some digital currencies support smart contracts, allowing transactions to be executed automatically under specific conditions.

How it works:

Digital currency operates through blockchain technology. The blockchain is a distributed and immutable account book that records all transactions. Each block contains a set of verified transactions and is linked to the previous block, forming a persistent and secure record of transactions.

Transaction verification is performed by miners distributed around the world by solving complex mathematical problems. Successful miners are rewarded with new digital currency, thus ensuring the security of the network.

Uses:

Digital currencies are primarily used for online transactions and payments, but their uses are constantly expanding. Some common use cases include:

• Remittances: Cross-border money transfers can be faster and cheaper using digital currencies.
• Payment: Online stores and physical stores are increasingly accepting digital currencies as a payment method.
• Investing: Some investors view digital currencies as an alternative asset class from which they hope to gain capital appreciation.
• Decentralized Finance (DeFi): Digital currencies are used to create new financial products and services, such as lending and exchanges, that are not controlled by traditional financial institutions.
