      An apt summary of most if not all of non-PoW protocols: "we solve distributed consensus on X by assuming we have solved distributed consensus on Y." In the process you'd get fancy terms like "randomness beacon" that sounds sophisticated, but in reality just obfuscates the issue.https://twitter.com/random_walker/status/1043613473974964224 …

      The consensus problem intuitively sounds trivial but is fiendishly hard. A common trap is to design protocols that assume a solution to consensus… without even realizing it. Prime example: "All nodes generate the same pseudorandom value by observing astronomical phenomena." https://twitter.com/random_walker/status/1043610027070754821 …

      You'd then get these diabolical white papers that go on for pages, filled with formulas no less, to prove the robustness of these protocols. All starting off of a circular reasoning fallacy. But math, right? 🙄

      I am constantly befuddled that everyone doesn't realize PoS is circular exactly as you describe. It's simply a logical error to think that you can somehow "fix" circular arguments.

      Maybe it's because Bitcoin itself has a certain circularity...BTC is valuable b/c it's secure b/c PoW is trustless b/c of incentives which only exist b/c BTC is valuable... But a virtuous cycle is a different circularity than begging the question.

      yeah I wouldn’t call that circular reasoning, that’s just positive feedback loop.

          How is PoS different in your mind?

          Or rephrased, can you be more specific in your criticism of circularity?
