The Lightning Network community is proposing a reputation scheme to mitigate channel jamming attacks. Reputation will be tracked locally for each node's peers, based on their history with forwarded HTLCs. The reputation is slow to build and fast to degrade, and sudden changes in behavior are short-lived. Data gathering on repeat interactions from individual senders is of interest to determine the use of local-only reputation-based systems. The community plans to gather data on HTLC endorsement and local reputation tracking for jamming mitigation. They want to observe the effect of endorsement in steady state, gather real-world data for simulation work, and experiment with different algorithms for tracking local reputation.Nodes will allocate slots and liquidity based on reputation, and forwarding of HTLCs will depend on endorsement by high reputation peers. The email also discusses the upcoming call for channel jamming and provides links to relevant GitHub pages. The Lightning-dev mailing list serves as a platform for discussing and developing the Lightning Network. Reputation systems are discussed, noting their vulnerabilities and potential usefulness. The issue of gossiping about reputations is addressed, stating that only information about endorsing HTLCs should be communicated. The discussion concludes that reputation systems are not a core issue but rather an API or plugin matter. The mailing list also provides updates on the development and implementation of Lightning technology.The email text discusses the concept of mitigating channel jamming in a two-part scheme. The first step proposed is endorsement and reputation, which would be used for slow jams that can be easily detected as misbehavior. The second step involves using unconditional fees for quick jams that are difficult to detect. This approach aims to address channel jamming by ensuring there are slots and liquidity available for unknown HTLCs. The email does not provide any specific links or references.
