> Hello, list,
> I haven't closely following the Lightning Network's state of affairs since late 2018 and I wondering, is it possible to support the following use-case with LN:
> 1. A user subscribes to the service by opening a channel with it
> 2. User sets his LN node to "trust" invoices that come from said service
> 3. On subscription renewal, service sends an invoice to the client's LN node
> 4. Since the client's node is "trusting" service's node, it pays invoice straight away
> User, of course, may cancel the subscription at any time by removing service's LN node public key from the list of "trusted". Or the user can set a limit on the amount and the frequency of payments that would be accepted from the trusted node.
> For that matter, the questions are:
> 1. Is it possible to send invoices just by LN means? (Should we use TLVs?)
> 2. Is it possible to enable automatic machine-to-machine payments? As in the example above, by accepting invoices from "trusted" nodes.
