What is a Watchtower?

Watchtowers are an important component of the Lightning Network, which is a second-layer Bitcoin payment channel network. Their main purpose is to protect users from potential fraud or attacks from their channel partners. A Watchtower is your shield against potential threats in the Lightning Network. It ensures your transactions remain secure even when your node is offline.
Watchtowers are services that constantly monitor users' payment channels. If a node on the network attempts to send a fraudulent transaction through a channel, the watchtower intervenes immediately, sending an emergency closure transaction to safeguard the funds of the involved users. Watchtowers are particularly useful for users who cannot constantly monitor their payment channels, such as if they are offline for an extended period of time. In this case, the watchtower continues to monitor the channel for them and intervenes in case of any issues. It's worth noting that the use of watchtowers is optional. Users can choose not to use them and monitor their payment channels independently. However, for anyone looking to have an extra layer of security on their Lightning Network payment channels, watchtowers are a recommended choice.
