Does the Lightning network use blockchain?

Is Lightning network still blockchain technology or not anymore?


The Lightning Network is a protocol that builds on top of a blockchain and uses cryptography to allow value to be transferred between untrusted parties outside of the blockchain, giving these value transfers the ability to handle increased capacity. But the Lightning network is built on top of a blockchain (hence it's known as a "layer 2" solution) because the value transferred in the network is funded by and settled to the originating blockchain.

    so... is it a YES or a NO ? – Nulik Nov 8 '17 at 15:57

    I would characterize the lightning network protocol as a blockchain technology, yes – Eric Allam Nov 8 '17 at 16:00

    but how can it be blockchain technology if its protocol doesn't have its own blockchain. Bitcoin would be blockchain technology, but Lightning network shouldn't , according to common logic. With your logic, any technology working on top of a blockchain would be blockchain technology too, even if it doesn't have its own blockchain. – Nulik Nov 8 '17 at 16:28

    I don't think this is the place to argue semantics. Eric gave an elaborate answer, but he can't know what you mean by the term "blockchain technology", which is a vague as it gets. – Pieter Wuille Nov 8 '17 at 16:42
  • @PieterWuille the obvious thing for a "blockchain technology" is to have a blockchain. do you agree ? But Lightening Network does not have one – Nulik Nov 9 '17 at 17:34
