Ethereum bitcoin address sample
Ethereum bitcoin address sample we get deeper into the concept of Ethereum Blockchainit is important to understand how Public Key, Private Key and Address are generated. To make this easier for beginners, Ethereum bitcoin address sample am trying to explain the technical concept with an example. Ethereum key generation is based on elliptical curve ecpk1.
A good library generate a private key with taking sufficient randomness into account. For this exercise we will take "1" as private key which is an acceptable private key because it lies in specified range mentioned above.
Ethereum requires private key to be bit long. Here is the sample code for nodejs. This is done using group operation of EC cryptography. To derive public key, private key is multiplied by G.
Multiplication used to derive public is EC multiplication which is entirely different from normal multiplication for which I ethereum bitcoin address sample going to use JS library. G is called generator point which is one of the domain parameters of EC cryptography. G has fixed value for ecpk1, which is recommended by experts. For a given ethereum bitcoin address sample key, pr, the Ethereum address A pr a bit value to which it corresponds is defined as the right most bits of the Keccak hash of the corresponding ECDSA public key.
To generate Ethereum address, take Keccak hash of public key. Right most 20 bytes is your Ethereum address. This is just an example to understand the concept.

The format of your private key is 3abf45abad64ccb3bf7faacbfe88fdd9ad8fe Note that there is a lowercase version 0xc2d7cfdbc7cd3f9 and a partially uppercase version 0xC2D7CFDBC7cd3F9.
The partially uppercase version has a checksum to verify the address. See EIP55 - Yet another cool checksum address encoding. You can generate a new Ethereum account by executing geth account new if you already have the geth Ethereum node software installed:. Here your account or address is 0x4e6cf0ed2d8bbf1fbbc9f2aceba4bf The contents of the file also includes an encrypted version of your private key. Again, you must retain the passphrase used to create the account.
Enter a password AND save this password in a secure location. Click on OKrepeat the same password and confirm:. Back this file and any other existing files in the same directory in a secure location. See Network Ports, Files And Directories for the location of the directories and files on your computer.
Enter a password in the following screen. You will have to remember this password, so save it in a secure location. Click on Generate Wallet:.
Your new wallet has been generated. Click on Download and download the file onto your computer. Back this file up in a secure location. Click on I understand. In the following screen, you will see the sample private key 85e3d0b2bbd00ae5cdc4aed6afbf2bdae. Save this private key in a secure location. You can print a paper wallet from the following screen:.
In the following screen, you upload the JSON file you just created, to test the new new account:. You will see your account sample 0xdd4eccddf50c27aebb14d99bfdb6 in the following screen. You can provide this address publicly to receive funds into your newly created account. See How are ethereum addresses generated? See Account uniqueness guaranteed? See Public key vulnerable to brute force in the future? You store your ERC20 tokens in the same account you use for storing ethers.
You can store ERC20 tokens in an account with 0 ethers, but when you want to transfer the tokens from your account, you will need some ethers to pay for the gas required to transfer your tokens. From How can I recover or reset a lost wallet password? You will need to provide some password hints for the application to attempt finding your password. The easiest way is to use the View Wallet Info tab in https: Your private key will be displayed in the next page.
