RE: Steem Witnesses - Weighted votes based on ranking
I think the key question is how many witnesses can one entity control. Dividing stake into more accounts could increase the number of witnesses that one entity can control if that entity has sufficient stake to do so. In the current system dividing stake is not necessary as each account has 30 equally weighted votes. Reducing the number of votes or reducing the weight of votes based on a rank would likely offer incentive to an entity to divide stake between accounts to obtain more witnesses. If the number of votes are reduced sufficiently or if the weighting is heavily skewed, it becomes close to impossible for one entity to control the required 17 witnesses as their stake supporting witnesses is greatly reduced by dividing the stake into several accounts. I explain in detail in another post using an example of reduced number of witness votes.
Yep, I get that. And I read your post which was again well detailed.
The downsides that I see from reducing the number of witness votes are ones which you have also mentioned:
On a positive note, Steem is becoming less susceptible to centralization as newly created Steem is getting distributed to more users. It is also difficult to buy a sufficient amount of Steem from exchanges to have a strong influence on the blockchain. The only way to do it is to buy large accounts such as the Steemit accounts. Even these accounts hold a considerably smaller proportion of stake compared to what they held a few years ago.
