Thank you for inviting me!
To know the difference between them, we must first know their definitions.
Digital currency: DIGICCY for short, which means "number" in English.
The abbreviation of Currency (digital currency) is an alternative currency in the form of electronic currency. Digital gold coins and cryptocurrency belong to digital currency.
Blockchain: Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, * * * * identification mechanism and encryption algorithm. Blockchain is essentially a decentralized database, also known as a trusted machine.
From the above definition, we can know that blockchain is a technology and digital currency belongs to virtual currency.
Digital currency is not equal to blockchain.
Many people will understand the blockchain as a blockchain. I want to correct it here. Digital currency is not equal to blockchain. Digital currency is only an application of blockchain, and some digital currency may not have applied blockchain technology.
