I strongly support many of these changes. Particularly, if the SEC decides to come after Steem because of the premining issue, Calibrae may well prove immune, because of the changes you intend.
I would, however, not disburse all those vests right off. There has been some fluctuation in rewards due to HF19, and how the pool was drained quickly. I reckon maintaining more of a pool could moderate fluctuations, and people would find that easier to count on.
I was raised in Alaska, and royalties on the oil industry were accumulated in a permanent fund. The interest generated from this fund not only made it possible for Alaska to not tax it's citizens, it actually paid them by disbursing interest accrued on the account that was not required by state government.
When I was a kid, Alaska paid us ~$1,000/year, just for being an Alaskan.
Give this some thought. It's possible that keeping a healthy vest fund, rather than simply expending that fund quickly, may be something beneficial to the platform, and the community.
I also like the idea of one issue per HF. HF19 was difficult to parse, because it did two diametrically opposed things. Did selfvoting dramatically increase because minnow votes were worth more, or because there were far fewer votes being cast?
While I reckon the latter more convincing, I've seen no data that proves either supposition. One issue per HF would make it much easier to understand the difference between what was expected to happen, and what did happen, as a result of the change.
Have you considered removing the weighting of VP by SP, and thus removing the currency from the SEC's jurisdiction? I have posted and commented profusely on other problems that arise from this 'feature' of Steemit.
However, getting the SEC off our backs is pretty damn compelling.
Thanks for your hard work and careful thought that has gone into this post!
I only commented sparely, because I am all too given to bloviation =p
I do like very much that you intend to mitigate stake with rep. I reckon it's a great step forward, as rep is community vetting (which will matter much more when bots are incapable of influencing it).
I am not a coder, and much of the guts of the system you are making are above my pay grade. I am also mentally incapable of parsing further the rep/stake weighting of VP, at least until I see a particular implementation.
I'll look forward to further development. I am greatly interested!
