      well the double-spending was plausibly described in multiple threads as broadcast the transactions, and have a byzantine agreement protocol to keep it to a single view several times on the list even by 1998. and in that thread ^ you're saying the remaining problem is inflation.

      we know now that controlling inflation is possible in a decentralised way via Bitcoin's mining difficulty adjustment. but I don't think anyone figured that out before despite exploring the problem for 10years +/- b-money & bit-gold approach were not that decentralised @NickSzabo4

      Making non-fungible bit gold was decentralized. Making it fungible required a ShapeShift-like exchange, which at that time would have had to have been centralized.

      Non-fungible Bitgold is centralized in the same sense that stocks are centralized: sure there are thousat and thousands. But each one is a centralized system.

      To avoid confusion, what do you think non-fungible Bitgold is?

      I think in the bit-gold model there was proposed to be a collectible market collecting up different scarcity stamps, into standard value bundles. those specialised dealers would not be so decentralised as a market function.

      But concretely, what prevents double spends in that model?

      That's a preposterous way to describe its flaws. It is decentralized, but in a flawed way (vulnerable to Sybil attack) which Nakamoto greatly improved upon. In any case, it was the state of the art in secure decentralization in 1998, nobody knew how to do it any better.

          1998 simply didn't have decentralized consensus. There's no reason to sugar coat it - it just hadn't been invented.

          you have to start somewhere. if anything I think that's the biggest under appreciated path where projects stall where they could have succeeded: fear of the good enough vs hypothetical best. good enough can be improved, and a sort-of-functioning system aids further realisations.

          I firmly believe that the discussion we had was starting well behind the starting line. It would have been *better* to not have to overcome those wrong ideas and start from a clean slate.
