Lightning Network Watchtower
Watchtowers send LN justice transactions when they detect an outdated channel close.
If your node goes down for extended periods of time, there is a possibility of an attack on your channels. A node on the other side of your channel may attempt to force close with an earlier state where they had more of the funds on the channel than the current state is. In this scenario, watchtowers will send a punishing transaction on your node's behalf, taking all the funds of the attacker on the channel and sending them to your node's on-chain wallet.
Watchtowers on LN can only issue the punishing transaction if an attack was detected and can not change the transaction. Therefore, as a watchtower client you don't need to trust the watchtower. You can add more than one watchtower to your node. Learn more about LND Watchtowers.
