The reward can still be low because you can choose many watchtowers. If you have a high value channel, you could choose for example hundreds of watchtowers. Only the first one to broadcast the revocation would get the reward.
The reward only has to be high enough for it to be worthwhile for other nodes to spend a small amount of memory storing your txn.
- dragontamer 7y agoWhat's the point of being a watchtower if only one watchtower gets the reward? In the case of 100x watchtowers watching one transaction, each watchtower only has a 1% chance of actually getting the reward.
- aeternum 7y agoIt's true, I believe the low probability of getting the reward is the greatest flaw with the watchtower reward scheme. Not just if you have many watchtowers, but the likelihood of a peer attempting a channel breach in the first place esp. when watchtowers are in place would be extremely low since that peer is almost certainly assured to lose money. There are some services currently providing watchtower for a flat fee instead, and the going rate is low (1 satoshi / txn watched) =~ $ 0.00008
