After learning about all sorts of new Bitcoin L2s, Lisa Neigut (aka Nifty). my very first podcast guest, has returned in person to lecture me about why Lightning Network is still the best!

Lisa’s “lightning maximalism” is rooted in “payments maximalism.” If you purely intend to expand bitcoin’s utility as a payments tool, she argues that lighting – in conjunction with federated protocols and ecash mints like Fedi – can get the job done. Much to my surprise, those two worlds have been building roots together and creating synergies for some time, including through wallets like Aqua that make Liquid and lightning interoperable.

Nifty says that lightning is becoming the high-speed “connective tissue” between several Bitcoin L2s, with swap providers like Boltz. These trustless swaps are a special quality of lightning that Ethereum wishes it could have to keep its L2 ecosystem together.

Nifty is the founder of Bitcoin++, co-founder of Base58, and a former Lightning Network engineer at Blockstream. Listen to learn more about one of Bitcoin’s OG Layer 2s, and hear an expert’s defense for it despite all the recent FUD!
