Splice Signing Order Woes

Imagine a three node network with two channels

A <-> B <-> C

Let's say B would like to perform two splices:

splice-out 10M sats from A <-> B
splice-out 10M sats from B <-> C

IMMEDIATELY AFTER RECEIVING CHANNEL_REESTABLISH

  • Do we have any active inflight splices?
    • Yes:
      • does latest splice inflight have commit and remote sig?
        • Yes: continue
        • No: send next_funding txid of latest inflight candidate, then, continue
      • peer sends next_funding value of:
        • None: Have I sent splice tx signatures?
          • Yes: Have I received splice tx signatures?
  • Yes: send nothing

Go through rebase conflicts that don't delete any code and auto-fix them.

ddustin / Splice locked ack flow
Last active June 26, 2023 14:12
splice_locked ->
<- splice_locked
(Whichever side has lower funding pubkey starts STFU)
STFU ->
<- STFU (ack)
splice_locked_ack ->
<- splice_locked_ack
Receiving splice_locked_ack ends STFU mode and
means we can atomically move to the new channel
confirmed state.

ddustin / SPLICE LOCKED Race Condition
Last active April 4, 2023 19:44
Legend:
Item -> means sent
Item <- means received
Chan X (implies a channel at block height X)
(Since these happen at different times)
Splice locked race condition example
Node A. Node B.
