Addresses can be generated at no cost by any user of Bitcoin. It is also possible to get a Bitcoin address using an account at an exchange or online wallet service. Also you can generate it offline and store on paper or at any digital storage. Bech32 type starting with bc1. Script hash P2SH address. Bitcoin address format Bitcoin address is an identifier like account number , starting with 1, 3 or bc1 on the mainnet, containing alphanumeric Latin characters and digits except 0, O, I.
Most of these conversions are called hash functions. Instead, we will look at how using these functions in the correct order can lead you to the Bitcoin wallet address that you can use. There is a whole family of such curves that are widely known and used. Bitcoin uses the secpk1 curve. This consists of two byte integers that represent the X and Y of the point on the elliptic curve, concatenated together.
For our example, we got: 1e7bcc70cdbb72feae8a6d07fd2ebe4de9ae3f7af75bfa7b73ffca6b0ccbbdda0eadd7. Note: as you can see from the code, before I used a method from the ecdsa module, I decoded the private key using codecs.
This is relevant more to the Python and less to the algorithm itself, but I will explain what are we doing here to remove possible confusion. The first is a string and the second is a byte array. The result is a Bitcoin full public key, which is equal to: e7bcc70cdbb72feae8a6d07fd2ebe4de9ae3f7af75bfa7b73ffca6b0ccbbdda0eadd7 for us.
But we can do better. As you might remember, the public key is some point X, Y on the curve. We know the curve, and for each X there are only two Ys that define the point which lies on that curve. So why keep Y? Later, we can derive Y from that if needed.
Now, we add the 0x02 if the last byte of Y is even, and the byte 0x03 if the last byte is odd. In our case, the last byte is odd, so we add 0x03 to get the compressed public key: e7bcc70cdbb72feae8a6d07fd2ebe4de9ae3f7af75bfa7. Previously, wallet software used long, full versions of public keys, but now most of it has switched to compressed keys.
From now on, we need to make a wallet address. Whatever method of getting the public key you choose, it goes through the same procedure. Obviously, the addresses will differ. In this article, we will go with the compressed version. The order is important. What matters is that now we have bit integer, which will be used for further modifications.
For our example, the encrypted public key is abb8d73dac84d7e8b. The Bitcoin has two networks, main and test. The main network is the network that all people use to transfer the coins. The test network was created — you guessed it — to test new features and software.
