> and it's not bitcoin; it doesn't have the same assurances, there are some third-party channels that route the transactions. (I admit, I haven't studied LN in detail.) lightning clients pass around bitcoin transactions to each other, check the protobufs: https://github.com/ElementsProject/lightning/blob/2bf92c906326d299e42317cc15727edf845b16ca/lightning.proto https://github.com/ElementsProject/lightning/blob/2bf92c9063... admittedly the protobufs have changed since i last looked, here's the canonical diagram describing the hashed timelock bitcoin transaction concept: https://github.com/ElementsProject/lightning/blob/2bf92c906326d299e42317cc15727edf845b16ca/doc/htlc.svg https://github.com/ElementsProject/lightning/blob/2bf92c9063... or read the paper https://lightning.network/lightning-network-paper.pdf https://lightning.network/lightning-network-paper.pdf > LN specifically requires segwit false, see http://diyhpl.us/wiki/transcripts/scalingbitcoin/hong-kong/overview-of-bips-necessary-for-lightning/ http://diyhpl.us/wiki/transcripts/scalingbitcoin/hong-kong/o...
