Staking details will be as follows: 3 rebases a day, one every 8 hours or so (It is based on block times so it is not 8 hours exact).
3 rebase warm up period (once you stake, you may not remove your stake for three rebase periods or one full day)
Target APY is 5% on the 5 day period.
NO sell taxes upon un staking, only selling. Upon launch, the protocol must compile data based on total stakers, amounts etc. initially so the first rebase will not generate any rebasing rewards, however being staked prior to the first rebase can be beneficial.
