Facebook Libra Is Architecturally Unsound
I don't disagree with the article per se, but I think many technologists are missing the forest for the trees when it comes to the motivations here. Or perhaps they're being charitable and are evaluating Libra on purely on its stated motivations rather than the ulterior motive that Libra can't name out loud. For example, take this quote:"The possibility that a Libra node run by Mastercard or Andressen Horrowitz would suddenly start running malicious code is such a bizarre scenario to plan for and is better solved by simply enforcing protocol integrity and through non-technical (i.e. legal) means."It goes without saying that Libra isn't concerned about any sort of security event at Mastercard or a16z. The purpose here is simply to evade and arbitrage different regulatory regimes. The plan is to build a ledger that no single party (or coalition of parties in a single legal jurisdiction) has the capacity to edit or alter, and to make such alterations so technically challenging that it's beyond the capacity of any single court or legislature to do so. Once this chain is up and running, it becomes a "fact of nature" that courts and policymakers will simply have to deal with.It's a brilliant strategy from that perspective. It's going to be alternately fascinating and horrifying to see if it works.
