The stakeholders are going to vote for the Notary, but how is it's going to take place and when?
The current plan for the first election is that the voting would happen when people redeem their KMD, or some short of other temporary procedure. For the later elections we must develop a better system, and about that we currently have no info. jl777 is thinking the best way to implement it.
For the first election it is possible that we don't even get 64 candidates, so there's a change there won't really be any meaningful elections. We will see.
Hopefully a way can be found to let BTCD holders still vote even if they keep staking and don't redeem before the election.
