The state machine approach I described doesn't necessarily require blocks or even miners to exist at all. Rather, it assumes that a single-use seal primitive is available, and a random beacon primitive for tx linearization, and then builds a system on top of those primitives. Transaction data - the proofs that certain states have been reached in the system - does not need to be broadcast publicly; if Alice wants to convince Bob that she has given him money, the only person who needs that transaction (and transactions prior to it in the tx history) is Bob. So as to your question about miners assembling blocks, and what blocks contain: there doesn't need to be blocks at all! Transaction history linearization is something your wallet would do for you. -- https://petertodd.org 'peter'[:-1]@petertodd.org
