Address

A crypto address is a unique string of characters that represents a wallet that can send and receive cryptocurrency. It is akin to a real-life address, email or website. Every address is unique and denotes the location of a wallet on the blockchain.

Most blockchain addresses are difficult for humans to read, as they take the form of long random strings of letters and numbers. 

Blockchain addresses are public and you can utilize a blockchain explorer to see the transactions in and out of an address. You can also see the amount of assets that the address has. The only exception is the privacy-based blockchains (eg. Monero).

Even though addresses are public, most of the addresses are anonymous (or rather, pseudonymous) as the person owning the address does not usually have their real name associated with it. However, there are cases where addresses and the person or entity behind them are known: this is usually the case for exchanges and token project owners or founders.
