Timur Badretdinov In the first article of this series, we generated a bitcoin private key: 60cfdbc59d31cc8e5cf5e45bab85b79cb32a9f3da9efc2.

Creating the Bitcoin wallet address from the private key is a bit complicated. Here, the process will be much simpler.

What is an ethereum address

We need to apply one hash function to get the public key and another one to get the address. Public key This part is almost identical to what we discussed in the Bitcoin articleso if you read that one, you can skip it unless you need a refresher.

Blockchain Address 101: What Are Addresses on Blockchains?

There is a whole family of such curves that are widely known and used. Bitcoin uses the secpk1 curve. Ethereum uses the same what is an ethereum address curve, secpk1, so the process to get the public key is identical in both cryptocurrencies. By applying the What is an ethereum address to the private key, we what is an ethereum address a byte what is an ethereum address, which is two byte integers that represent X and Y of the point on the elliptic curve, concatenated together.

For our example, we got 1e7bcc70cdbb72feae8a6d07fd2ebe4de9ae3f7af75bfa7b73ffca6b0ccbbdda0eadd7.

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 https://catalogshow.ru/address/wallet-address-validate.html second is a byte array.

Now, unlike Bitcoin, Ethereum what is an ethereum address the same addresses on both the main and all test networks. Users specify the network that they want to use later in the process when they make and sign a transaction. To make an address from the public key, all we what is an ethereum address to do is to apply Keccak to the key and then take the last 20 bytes of the result.

Ethereum Wallets for Beginners AND Experts

No other hash functions, no Base58 or any other conversion. Initially, there were what is an ethereum address checksum mechanisms to validate the integrity of the key. However, inVitalik Buterin introduced a checksum mechanism, which has since been adopted by wallets and exchanges.

Adding a checksum to the Ethereum wallet address makes it case-sensitive.

First, you need to get the Keccak hash of learn more here address. Note that this address should be passed to the hash function continue reading the 0x part.

Second, you iterate over the characters of the initial address. Finally, you add 0x back at the start of the resulting string.

The checksum address is the same what is an ethereum address the initial what is an ethereum address if you ignore the case. But the uppercase letters let anyone check that the address what is an ethereum address indeed valid.


You can find the algorithm of the checksum validation at the page linked here. All we need to do is to apply the ECDSA to public key, then apply Keccak, and finally take the last 20 bytes of that what is an ethereum address.
