Ethereum: Creating Unique Addresses Based on Human Readability
The Ethereum blockchain has introduced various concepts to improve the user experience and verify transaction validity. One such idea is to generate unique addresses based on certain characters, similar to how SHA256 hash functions validate transactions. In this article, we will explore the concept of creating unique Ethereum addresses that start with certain characters, such as “JoeAnonymousUserB7pMqyVa8JRcpZdCQLQ”.
Problem:
In the current system, most Ethereum wallets require a 42-character alphanumeric string to generate an address. This string is generated using the SHA-256 hash function, which makes it difficult for humans to read and understand. For example, consider the following example:
0x...
This hexadecimal representation of the number 0x000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 raistable habitat and unreadable yes.
Solution:
To create unique Ethereum addresses based on human readability, we can use a custom hash function that includes certain characters in the address. One possible approach is to use theb58addressencoding scheme, which converts hexadecimal numbers into human-readable strings using a combination of letters and digits.
Let's see how this works with our original example:
0x…
To create a human-readable address that starts with "JoeAnonymousUserB", we can combine these characters with other alphanumeric characters. One possible implementation is to use theb58addressencoding scheme, which generates an address like this:
JoeAnonymousUserB7pMqyVa8JRcpZdCQLQ
This encoded string is more readable and easier to understand than the original hexadecimal representation.
Implementing Custom Hash Functions:
To generate unique Ethereum addresses based on specific characters, we can implement custom hash functions that include those characters in the address. For example:
- ASCII Encoding: Use the ASCII values of the characters to generate a 42-character alphanumeric string.
- B58Address Encoding Scheme:
Convert hexadecimal numbers to human-readable strings using b58address
.
- Custom Hash Algorithms: Implement your own hash algorithm that includes specific characters and uses theb58address
encoding scheme.
Sample code:
Here's an example of implementing a custom hash function in Solidity, which generates addresses starting with "JoeAnonymousUserB":
“firmness
pragma solidity ^0.8.0;
import “
import “
contract CustomAddressGen {
function generateAddress(string memory _firstChars) public return (address) {
// Convert ASCII character values to hexadecimal
uint8[] memory asciiValues = new uint8[](_firstChars.length);
for (uint256 i = 0; i < _firstChars.length; i++) {
asciiValues[i] = uint8(bytes(_firstChars[i]));
}
// Generate a random 42-character alphanumeric string using ASCII values
string memory hexString = “”;
for (uint256 i = 0; i < 42; i++) {
uint8 charCode = asciiValues[i] % 10;
charCode += 32; // Capitalize for readability
if ((i & 1) == 0) { // Add only the letter character
hexString += string(charCode);
} else { // Add a digit
hexString += string(uint8(asciiValues[i]));
}
}
// Convert a hex string to an address using the b58Address encoding scheme
memory byte encodedHex = abi.encodeWithSigner(address()).param(0, byte(hexString));
return eIP55Addresses().
