I've noticed more activity recently on the LND github page.
Particularily here: https://github.com/lightningnetwork/lnd/tree/master/watchtower
Watchtowers are coming!
What is a watch tower?
A watch tower watches transactions on the LN for you and checks for counter-party cheat (which reveals a cryptographic secret). Using this, the watchtower is then able to transmit a punishment transaction and sweep the funds from the cheater into your wallet.
Of course, your node can be online to watch for this, but a watch tower serves as a backup in case your node is offline for a long time.
Watchtowers are already available for the Lightning Bitcoin Wallet on android.
With this security feature, LN will be even easier and safer to use!
Hi
I don't see this feature on Lightning Bitcoin Wallet? No settings called watchtower or so.
On LBW, it's called Olympus Server. They charge a small fee to watch your channels. It was discussed here in a medium post.
Ok, now I understand the reason behind those servers, I thought they are only for backups
