Thank you for another vote to proceed. As I said, I am taking a market survey, so I am counting these.

Realize that the disk-space Proof-of-Work is not critical for fixing the design flaw in Bitcoin that allows cartelization. The only required fix is to not stop making new coins. This was called "inflatacoin", but it is only a very small rate similar to gold which is debased roughly 2.5% per year (consider it a storage fee if you want). This is not inflation, it is funding your miners and keeping the ecosystem from degenerating to cartelization.

I hope you all know that Rockefelller got his opening, because of the bottleneck of the railroads and that creating railroads cost (on an opportunity cost yearly ROI basis) "more" than could be earned from the fees of transport. So it is analogous in that way and also where there could be two competing railroads, then better to form a cartel than drive each other bankrupt (remember this is very large capital so it is ripe for political capture too). Remember all utilities end up under the control/regulation of the government. The cellular wireless networks are similarly heading this way for the same reasons.

My proposed disk-space Proof-of-Work improvement is a separate improvement, as are my proposals to increase anonymity, make transactions faster, fix micropayments, etc. Many improvements I am proposing over current Bitcoin.
