You know, I've noticed you've spent a tremendous amount of time and
energy on this list promoting these kinds of metrics; obviously you're
somewhat of an expert on this compared to the rest of us.
Why don't you look into spearheading one of these analyses yourself to
show us how it's done?
> The idea is to come up with some sort of standardized metric so as
> the tools and issues come up you are comparing similar things.
>=20
> The first thing you have to do is link "centralization pressure" and
> (pressure to merge with a big miner) to some sort of overall
> decentralization metric. For instance, how much do big miners
> reduce decentralization to begin with? That is a complicated
> analysis on its own. Then you can measure specif use cases with a
> tool like that.
>=20
> the idea at least is that the metrics do not "take sides" on any
> issue and just provide a measure of whatever it is you are
> measuring.
>=20
> most of the references have to do with measuring decentralization in
> political systems so a system would need to be developed to apply to
> software projects like Bitcoin:
