Gas efficiency - [John packel] can it be quantified? → Piotr’s comments on the PR introduce the numbers.
Before this change:
for group size 64, gas cost: 3 142 093, for group size 100, gas cost: 4 860 500. After this change:
for group size 64, gas cost: 1 720 849, for group size 100: gas cost: 2 639 758
Change the behaviour of the staking contract in case an app receives a decrease authorization (e.g., reduce the stake size), the app decides whether the decrease is authorized.
Allowing top-up a stake: e.g., in a single transaction claim the rewards and re-stake.
Minimum stake 40K: they were not allowed to stake 40K (before needed to be 40K and a little bit more).
