Lightning and Raiden are payment channel networks for Bitcoin and Ethereum respectively. Is there any difference between these projects in terms of architecture, or is Raiden simply an Ethereum implementation of Lightning?

  • Channels in Lightning are designed to have a lifetime, while a Raiden channel can run forever

  • @neuromouse Cn you provide the source? From what I understand from the Lightning paper, Lightning also have an infinite lifetime (due to breach remedy transactions). Commented Dec 10, 2017 at 23:20

  • I've stuided a bit about how Raiden works, but haven't spent much time on Lightning. The source is from a Raiden developer on a podcast, so it might not be reliable: player.fm/series/oktahedron/oh007-raiden

The Raiden FAQ states that it supports ERC20 tokens instead of just Ether. Going a step further, Raiden 2.0 wishes to generalize state channels in order to make faster dapps.

  • Could you elaborate? I've spend quite some time wrapping my head around the mechanics of Lightning (commitment tx's, breach remedy tx's, timelocks, etc). I'm wondering, to what extend does Raiden port those to Ethereum, considering the completely different account structure (UTXOs vs account balances)? Commented Dec 9, 2017 at 19:07
  • I cannot. Now I see what you mean by "architectural." This might be detail that you can only get by reading source code.
