      Consensus is only provably secure if there is complete broadcast: every node broadcasting to every other node. That's impractical, but we should move closer to that ideal, each node communicating directly across as many internet bottlenecks as feasible to prevent eclipse attacks.https://twitter.com/udiWertheimer/status/1082918393940987906 …

      Replying to @ercwl @peterktodd
      As noted, node operators can mitigate risks (have many redundant nodes+connections, use multiple ISPs, Tor, VPNs..). But do they? Peter and dontpanic suggest that some critical nodes aren't being attended to carefully. If that's the case, a successful attack will improve that :)
