Generate Jaxnet Vanity Address

This is fork of http://github.com/MarinX/btc-vanity project

What is jaxnet vanity address?

Vanity addresses are valid bitcoin addresses that contain human-readable messages.

For example, 1JAXeBPzzD72PUXLzCkYAtGFYmK5vYNR33 is a valid address that contains the letters forming the word "JAX" as the first 3 Base-58 letters. Vanity addresses require generating and testing billions of candidate private keys, until one derives a jaxnet address with the desired pattern...reference

Length of address

The frequency of a vanity pattern (1KidsCharity) and average time-to-find on a desktop PC

Length	Pattern	Frequency	Average search time
1	1K	1 in 58 keys	< 1 milliseconds
2	1Ki	1 in 3,364	50 milliseconds
3	1Kid	1 in 195,000	< 2 seconds
4	1Kids	1 in 11 million	1 minute
5	1KidsC	1 in 656 million	1 hour
6	1KidsCh	1 in 38 billion	2 days
7	1KidsCha	1 in 2.2 trillion	3–4 months
8	1KidsChar	1 in 128 trillion	13–18 years
9	1KidsChari	1 in 7 quadrillion	800 years
10	1KidsCharit	1 in 400 quadrillion	46,000 years
11	1KidsCharity	1 in 23 quintillion	2.5 million years

Using library

Install

go get github.com/tjaxer/jax-vanity

Use it as library

package main

import (
	"fmt"

	"github.com/tjaxer/jax-vanity"
)

func main() {

	// create configuration
	cfg := &jaxvanity.Config{
		// buffered channel, more buffer, faster to find matching pattern
		Buffer: 5,
		// if you want to use testnet, set true
		TestNet: false,
	}

	btc := jaxvanity.New(cfg)

	// find a patters eg adddress which starts with "ab"
	address, err := btc.Find("JAX", true)
	if err != nil {
		panic(err)
	}
	
	fmt.Println("ADDRESS\n%s\n", address.Address())
	fmt.Printf("PUBLIC KEY\n%s\n", address.PublicKey())
	fmt.Printf("PRIVATE KEY\n%s\n", address.PrivateKey()) // RAW Hex format
}

Use it as a CLI tool

go get github.com/tjaxer/jax-vanity/cmd/jaxvanity

Usage: ./jaxvanity [OPTIONS] pattern
Example: ./jaxvanity

  -help
        Show usage message
  -testnet
        Use testnet
  -threads int
        How many threads you want to spawn (default 16)
  -uncompressed
        Use uncompressed public key 

Tests

No magic, just run
