These are Hyperstake's vital statistics:
-X11 PoW blocks already phased out
-Proof of Stake Blocks Only
-90 Second Block Time
-Minimum Age - 8.8 days (rounded)
-Maximum Age - 30 days
-Annual Interest Rate - 750%
-Maximum Stake Subsidy - 1,000 HYP
-Recommended Block Size - 1,000-4,000 HYP
The timing specs we already have are quite close to the ones of HYP.
My personal opinion about HYP - it is a ponzi scheme: in a year the total supply would be ~13 times bigger than now with no real value behind this figure. You may consider my opinion as FUD in regard of HYP or as it has to be considered, i.e. as a critical view - it is up to you.
The maximum reward per block is a good thing and I was going to discuss it as well, I just waited until we finish with other parameters. The main purpose of having the maximum reward per block is not the inflation control but the network security enforcement: this maximum keeps people from merging their inputs into a single one and running a wallet once per staking period.
