Advertising Node Liquidity

A proposal by Lisa Neigut allowing LN nodes advertise their willingness to provide incoming capacity in exchange of fees in a “market” of advertised liquidity rates. This would help merchants to have access to incoming capacity which they need in order to receive payments from customers. The current alternatives would be either for customers to wait for on-chain confirmations and open a new channel or for merchants to make arrangements with other merchants that offer channel liquidity.

lightning-dissector: A Wireshark Plugin for Lightning Network Protocol

Nayuta, a team currently developing a new Lightning Network implementation called ptarmigan, announced the release of a wireshark plugin for the Lightning Network (BOLT) protocol. The plugin is hosted here.

It’s alpha version, but it can decode some BOLT message. Currently, this software works for Nayuta’s implementation(ptarmigan) and Éclair. When ptarmigan is compiled with some option, it write out key information file. This Wireshark plug-in decode packet using that file. When you use Éclair, this software parse log file.

Improving payment UX with low-latency route probing

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.
