A public address or public key is a cryptographic code that allows a user to receive cryptocurrencies into his or her account. The public key coupled with the private key are significant tools required to ensure the security of the crypto economy.
Everyone who owns cryptocurrencies (bitcoin, ether, …) has to have a unique identifier or address - much as you would with your bank account. This is the public address of your Wallet which you need to store your crypto assets.
What does this address look like?
It is a long series of numbers and letters like this one - mine, for example, is this:
Bitcoin Public Address:
Ethereum Public Address:
You are also given a Quick Response code (or QR code). You can send that to people, or they can scan it with the camera function on their smart phone to easily have your wallet address. It’s just a short cut rather than having to type out your full address which is rather long!
Like this one:
Should I worry about putting that on a public website!?
Not at all! This address is safe to give to anyone. It is like publishing your bank account number (IBAN), all you can expect is that someone sends you money. People can’t access your wallet at all if you publish your PUBLIC ADDRESS. So feel free to send me bitcoins if you wish! I will be very happy :).
