enabling ICA in the next upgrade seems very reasonable, so I’m certianly not blocking on that.
I do have some concerns over the proposed mechanisms to pick the validator set, however.
Copy Staking
The copy staking mechanism is really interesting. Long term, I am a bit worried about it however.
If stTIA becomes very successful, and say 50% of the voting power is copy staked, does that mean that if I don’t liquid stake, my voting power can be doubled? If so, then does that mean it only costs half as much to attack the network?
Does this mechanism need to account for other liquid staking protocols as well?
stTIA
If stTIA holders control a council, would this open us up to governance attacks? Meaning, would it be possible to buy or borrow a bunch of stTIA, set a malicous council, and then return or sell the stTIA?
stTIA Veto
similar to the above concerns, could an attacker borrow a bunch of stTIA and veto all changes? Have vetos occurred in other scenarios? If users are using their stTIA in defi, would this mean they would have to exit their positions to potentially save the protocol?
