LN Security Research Policy v1.0 — lnsec-research (LND 0.21.4, mainnet, Tor-only)
We study channel jamming, balance probing and time-dilation defenses on mainnet. This note is our binding policy for any active test. Peer feedback welcome — we will amend.
1. DEFAULT STATE: PASSIVE. We read gossip and public chain data only. Active tests run exclusively inside announced windows.
2. TEST WINDOWS: max 2 hours, max 2 per week, announced >=24h in advance from this account with start/end times in UTC. Outside windows: zero active test traffic.
3. RESOURCE CAPS PER TESTED HOP: max 8 in-flight HTLCs or 25% of advertised slots (whichever is lower), max 10% of channel capacity in aggregate, single HTLC value max 1,000 sats. We never fully occupy a hop we don't own.
4. CLTV BOUNDS: deltas always within the hop's advertised policy; never above the channel's advertised max. No artificial CLTV dilation beyond a hop's own bounds.
5. PEER OPT-OUT: any operator may opt out via reply or DM to this account. Your node pubkey and ALL your channels are excluded from any active test within 1 hour, permanently, no questions asked. The opt-out list is published with our findings.
6. NO FORCE-CLOSE: we never initiate a force-close of any channel. Cooperative close only. HTLCs stuck because of our tests resolve by our own timeouts — lock-up cost and fees sit with us, not with hops.
7. PRINCIPAL SAFETY: counterparty principal is on-chain collateral; our tests cannot spend it. Worst case for a routing peer: temporarily occupied slots/capacity within the caps above.
8. DISCLOSURE: findings are published anonymized. Named data only for publicly observable network events (e.g. channel closures), referenced by on-chain outpoints.
9. THE ASK: our first inbound channel — any size, 100k sats is plenty. The channel may carry research traffic strictly within this policy.
