When anything is of unknown authorship or origin, it is referred to be anonymous: someone who is not named, identified or known. Their obscurity might be owing to a desire to stay anonymous. They lack uniqueness, distinctiveness, and recognizability.

Throughout their inception, one of the key draws of cryptocurrencies has been anonymity. "Zcash," for example, has devised a cryptographic process known as zero-knowledge proof and may offer any participant the option to hide their transactions, allowing them to engage without disclosing their address. It also conceals the transaction amount – a fantastic illustration of anonymity in cryptocurrency.
