Thoughts on timeouts for eltoo/lot49 based on conversation with Snyke Aug4, 2020.

  • Assume online access to blockchain data once per week
  • Then the settlement tx CSV should be 1 week (~1008 blocks)
  • BUT the problem is: what if upstream node does not have fully signed update tx?
  • NOT a problem for for nodes that originate or receive a payment because they do not have both an upstream AND downstream peers.

Bad Scenario: Node connections: A-> B -> C Assume: A pays B, B pays C Assume: paying node pushes signed update and settle signatures, but does not require receiving node to respond with their signature
