To my understanding it is purely software thing. It cannot be detected from
outside if miner uses this improvement or not. So patenting it is worthless.

I&#39;d like to announce a white paper that describes a very new and

The fact that you&#39;ve chosen to patent this improvement could be a
centralization concern depending on the licensing model used. For example, =
