Would this new &quot;multi-party trusted setup&quot; happen to be based on a block chain of its own?<p>If so, then they&#x27;ve introduced a new sort of meta 51% attack potential in a system that gives no economic incentive to mine (i.e., 51% attack is much easier when its not &quot;51% of everyone trying to earn coins&quot;, but instead is &quot;51% of those donating computing to protect zero-knowledge proof&quot;), right?<p>If not so, then how?
