How to buy vanity Bitcoin address

There is an old utility vanitygen to generate vanity Bitcoin address, and your laptop is able to produce addresses with 5 characters (example: 1Anton***) in a few minutes. But if you prefer 6, 7 or more length this will be 60 or 3600 times longer. This is really weeks of work on your laptop.

Did you ever hear about split-key address generation scheme? This allows you to outsource vanity address computations in an absolutely secure way. No one will ever have access to your final private key. This is 100% cryptographically secure way to buy vanity addresses.

Recently I build Dapp on Ethereum for that: https://vipco.in – there are a few steps how to use it:

Install MetaMask plugin, or use any Ethereum wallet.
Get some VIP coins on an exchange or on smart contract on the top right corner of the website. You need it to pay for tasks
Create a task by providing:

Preferred address prefix, for example, 1Anton.
Reward, ensure your price VIP/GH is concurrent enough – miners usually select most paid tasks.
Public Key of any Bitcoin address you already own (needed for split-key address generation scheme)

Wait until your task is completed. You also will be able to increase task reward to speed up task processing. When it will be completed you’ll receive Private Key Part. You should add your secret Private Key which Public Key you used to create a task with Private Key Part found by miners. The result will be your Private Key to Bitcoin address with your desired prefix. You can perform addition in online calculator on the bottom of the Dapp web page.

P.S.
Also you can mine vanity addresses for other participants and earn VIP coins using this software: https://github.com/VipCo-in/VipCoinMiner
