đź“ť Original message:Very interesting paper. When you talk about a market, what are you
referring to exactly? A market means that demand and supply are matched
continuously, and Bitcoin has no such mechanism. A lot of discussion has
been around fixing the "supply" of blocksize. A floating number would mean
that a hardcoded number or function would be replaced by a decision process
involving users (demand). I don't think a fee market exists and that demand
or supply are not easily definable. Ideally supply of transaction
capability would completely depend on demand, and a price would exist such
that demand can react to longterm or shorterm supply constraints. In such a
scenario there would be no scalability concerns, as scale would be almost
perfectly elastic.
