Would this new "multi-party trusted setup" happen to be based on a block chain of its own?
If so, then they'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 "51% of everyone trying to earn coins", but instead is "51% of those donating computing to protect zero-knowledge proof"), right?
If not so, then how? (rewind to Jan 2, 2009...)
- jhasse 11y agoI haven't read the paper, so correct me if I'm wrong: I think the "multi-party trusted setup" isn't about a blockchain or something complex. It's just an algorithm to set up some initial values.
