Watchtowers coming to Lightning Network for next ugprade

posted 3 months ago
Lightning Network “watchtowers” — a next step for securing the network — are coming soon. Watchtowers have long been considered a missing piece of Bitcoin’s lightning layer, as they’re crucial for stopping fraud on the Lightning Network. Later this month, Lightning Labs plans to launch the most complete build of a network watchtower to date.

When someone uses Lightning, it’s necessary for someone using it to remain online to make sure their “counterparty” isn’t trying to steal those funds. But this is obviously a UX nightmare; The watchtower “watches” to see if a bad actor tries to broadcast an old transaction — giving themselves extra money — the watchtower responds by punishing that bad actor. Thus, watchtowers outsource this anti-fraud functionality so users don’t have to do perform this kind of monitoring themselves.
