Last week Rusty Russell started a discussion on LN protocol V1.1, focusing on the new payment models it would bring with it, along with experimental support of new technologies, we discover those technologies with the applications they might bring to Lightning.
Pending payments are a common UX problem for LN that users often complain about. While the cause of this problem is not easily unraveled, there have been several issues involving stuck intermediate nodes awaiting revocation and recipients who can’t give timely preimage replies.
Fabrice Drouin proposed a change to address the issue using a faster
“proceed/try another route” answer using a probe with a short timeout requirement.
The system sends the blank
probe request prior to sending the actual payment,
via the same route.
