Fiatjaf, the founder of Nostr, recently called the Lightning Network a scam, leading to some Bitcoin developers gradually leaving the network. Concerns about the complexity and security of the Lightning Network have been raised, and two developers have already announced their departure from Lightning Network-related work. Additionally, the network has experienced a significant loss of channels and nodes. Meanwhile, the Bitcoin ecosystem has been thriving, with the development of Bitcoin ETFs and the increasing price of Bitcoin. The criticism from the Nostr founder and the departure of developers have sparked discussions within the Bitcoin community [dab939e0].
