Is there a Blockstream dev currently working on LN? I thought sidechains like Liquid were more their angle.
[1] Lightning Network by Joseph Poon and Thaddeus Dryja (website), github repository (golang)
[2] Deployable Lightning by Rusty Russel (Blockstream), github repository (C)
[3] Thunder Network by Mats Jerratsch (Blockchain.info), github repository (Java)
The way i see it , the sidechain approach makes sense for now . It cannot be seriously used until the malleability is fixed by segwit. Once that's done, lightning will be developed for the real blockchain
