Digital assets are a type of digital or virtual money that is protected by cryptography, designed to be nearly impossible to counterfeit or reuse. Most digital assets are built on blockchain technology, which is a decentralized ledger technology maintained collectively by a distributed network of computers. The core feature of digital assets is that they are typically not issued by any central authority, theoretically making them immune to government interference or manipulation. This design allows for secure online payments without relying on third-party intermediaries. The term "cryptography" refers to various cryptographic algorithms and password technologies that protect these inputs, including elliptic curve encryption, public-private key pairs, and hash functions. Digital assets can be obtained through mining, purchased on digital asset trading platforms, or rewarded for completing specific tasks on the blockchain. Not all e-commerce websites support digital asset trading. In fact, even mainstream digital assets like Bitcoin have relatively limited applications in retail transactions.
