Private keys and addresses in three sentences:
An Ethereum address is derived from the last 20 bytes of the Keccak-256 hash of a public key, and is written as 0x followed by 40 hexadecimal characters.
Think of an address as an account for receiving funds, and a private key as the only credential for accessing those funds: you can share your account with anyone, but only you should keep your private key.
After pasting an address, double-check the first, last, and a few middle characters—don't check only the beginning and end.
