This will only work if the current node's mv.boldStakerAddress is the one that is staked on the chain (needs $10 million USD). We should instead fetch the latest assertion we locally agree with. I think we need to expose a helper method for this, and I can do this once I return from holiday

To test out multiple validations, we'll probably need to setup assertion posting...I can also help with this once Im back
