Or we could have forging bands where a certain level of coins would put you in a group.
For example, forging groups could be:
- Accounts > 4M
- Accounts [1M, 4M)
- Accounts [500K, 1M)
- Accounts [100K, 500K)
- Accounts [1K, 100K)
- Accounts [1, 1K)
Each subsequent block could come from a different group. Assuming less concentration at the top, that would encourage asset consolidation up to 4M and then a splitting of assets less than that.
(1) Bands with less accounts would be more desirable
(2) As people move to less occupied bands, the bands will reach an equilibrium where they all have ~ the same number of accounts
(3) Everyone or no one
It's just something I thought up of now, so I haven't fully thought it through.
forging groups may be good; then the richer are earning from other rich, and so on.
To avoid that someone splits his big account to n*999999, to get "better" forging,
the limits could be floating, changed by some algorithm (if not too difficult to implement).
But later, in active network, the tx fees may change the understanding of forging's effects/benefits.
