Nice and detailed overview of the Lightning and Raiden network. Both networks are built to strongly leverage their underlying blockchains and cryptocurrencies. Just like the lightning network could save Bitcoin, Raiden will help Ethereum scale. Besides Ethereum and Bitcoin, the two most widely used blockchains, the third major player is Grahpene created by Dan Larimer and runs services like Bitshares, Steemit and soon EOS. Blockbasis is also based on the Graphene blockchain, which does has built in scalability features already.
