Even theoretically, how can they do this? I don't see it happening, even setting aside the much rehashed mining electricity consumption issue.
Yeah, theoretically it just used $2 worth of electricity somewhere in the world, but I’m pretty sure PayPal is going to do something nefarious with the $100+ you’d have to give them for the same service
All the hype benefits of pretending to use blockchain, without ever actually using it.
The tldr is thst Lightning is as safe as bitcoin because it uses bitcoin under the hood.
The website you linked is just a collection of random (and often contradictory, just read a few of the “energy” topic) opinions posted on medium.
The person you’re replying to was (sarcastically? I would’ve been) suggesting a solution, which isn’t any of those things.
As there are different ways to use a thing, and everything I’ve seen of Lightning (network not cable) is using the Blockchain in roughly the same sense as a USD denominated bank that happens to not ban accounts from trading Bitcoin uses the Blockchain — i.e. it does, but it’s very much also pretending — this seems reasonable, if not literal.
