Any change would still be subject to the usual soft-fork rules, requiring a super-majority to be in favour of the fork before it activated.
Forgive me if I'm wrong, but doesn't that just mean if
-YOU- decide to do the update and fork?
Because you have [ control ] of the majority amount of clam?
Maybe I'm wrong, I'm not 100% sure of all facts. But its been the way I've been understanding this.
Yes, I could, but I won't. I don't consider the CLAMs in the JD bankroll mine. They belong to the investors. For the voting phase I will have JD vote according to the wishes of its investors. For any subsequent soft-fork phase, I hadn't thought about that until now. I guess I need to have an option for each investor to decide whether they want to go with the soft fork or not, calculate which percentage of the bankroll is in favour, and use that percentage to decide how many blocks to stake in favour of the fork. That works, right?
If we're going to get hung up on what I *could* do, I could right now decide to orphan all blocks not staked by JD and take all the block rewards for myself. Hell, I could just steal the whole bankroll and not let anyone withdraw. All of those things are pretty easy to detect however, and quickly trash the value of the CLAMs I'm holding.
So long as I stick to my word and allow the owners of the coins I'm holding to have their say (in voting and in agreeing to any forks) then I don't see a problem. Although of course it would be better if no single entity had custody of more than 50% of the coins.
