Hi guys.
There was such idea: if you want absolutely safe to generate the vanity address (outsource) it is necessary to use partial key. This is too expensive, you need to use all the processing power to generate one vanity address. My idea: use third-party services that will generate a private and public key (something like a certification authority center as GeoTrust, Comodo etc.). The public key will be used to generate a large number of vanity addresses, so they can be made much cheaper. In this case, the full private key can only be obtained using the private key of a third-party service.
Can it work?
