Fiatjaf is one of the most prolific developers in Bitcoin and Lightning. But despite contributing to lots of Lightning open source projects (including LNBits, Zeus, lntxbot, Alby), he is best known for creating and promoting Nostr: Nodes and Other Stuff Transmitted through Relays. Also, Fiatjaf reached a point where he resents the Lightning network to the point where he believes it should be abandoned entirely and replaced by Drivechains (as described by BIP300).
In some ways, Fiatjaf’s views appear to be contradictory to ongoing Nostr projects and narratives: Lightning zapping (a way for users to tip each other for posting good content, as introduced by Damus developer William Casarin) is currently one of the most popular activities among Nostr users who believe they can use this as a vehicle to support content creators. Also, the Nostr creative doesn’t agree with the ostrich logos and the use of the color purple to represent the project’s identity. Though Fiatjaf remains adamant that Nostr is a tool which protects free speech from censorship, such is the power of open source projects: anyone can build on top of them.
It should also be noted that Fiatjaf is not against the idea of zapping to send tips: he is, however, no longer convinced that the Lightning network is the optimal way to send small bitcoin transactions among users. He would rather see sidechains get built for such use cases, for the simple reason that the underlying technology offers a better user experience with virtually no chances of making participants deal with trusted custodians and potentially lose their funds. After being one of the most prolific Lightning network developers, Fiatjaf believes it’s time to abandon this second layer to focus on more secure approaches to scaling (Drivechains, Spacechains).
For the reasons presented above, this interview with Fiatjaf was particularly interesting. First of all, it was fascinating to see how the father of Nostr doesn’t agree with everything that the builders are doing – and that’s fine, as the network of relays don’t belong to him and he created everything with censorship resistance in mind. Secondly, I found it endearing to discover a Drivechains proponent who promotes the trust-minimized sidechain technology with an energy that matches Paul Sztorc’s. And thirdly, it was fun to learn about Fiatjaf’s ongoing projects: a decentralized alternative to GitHub and Wikistr (a Wikipedia version which enables multiple points of view to be told about the same person, event, or phenomenon).

Fiatjaf, Nostr and the Quest for Decentralized Social Media
My journey with Nostr began back in May 2021 when Ben Arc introduced me to this innovative platform. Initially conceived as a social media network, Nostr quickly evolved into something much more. Fiat Jaf and I reminisced about the early days, discussing the browser client Branle and the loss of my private keys — a common plight among early adopters of tech with uncertain future.
Nostr, which stands for “nodes and other stuff transmitted through relays,” was born out of a time when censorship seemed to be on the rise. Fiatjaf (who prefers to refer to himself as an anarchist rather than a libertarian), along with Ben Arc (his self-proclaimed left-wing anarchist coding partner) set out to create a platform that was immune to the whims of centralized control. The idea started out from a LNBits extension which ended up receiving an autonomous release.
The Lightning Network: A Path Paved with Challenges
Our conversation took a technical turn as we tackled the Lightning Network’s limitations. Fiatjaf shared his concerns about the network’s ability to handle small transactions and the financial disincentives for running a routing node. I chimed in with my own experiences, highlighting the technical hurdles and the lack of rewards for maintaining the network’s infrastructure.
We also touched on the complexities of implementing new features without introducing bugs, a constant battle for developers in the space.
Drivechains: A Glimmer of Hope for Scaling Bitcoin?
The topic of Drivechains sparked a lively debate. Fiatjaf described them as a more effective way to scale Bitcoin compared to the Lightning Network, despite the potential for increased human politics. I raised some popular concerns about BIP300 just for the sake of playing the devil’s advocate – only to discover that Fiatjaf has already made up his mind about his favorite scaling proposal.
The Battle Against “Shitcoins” and the Future of Commerce
Fiatjaf didn’t hold back his frustration with the proliferation of shitcoins cluttering the market. He emphasized the need for solutions like Drivechains to keep Bitcoin at the forefront of the financial revolution. After the guest suggested that Bitcoin must be built with the future users in mind, I pointed out to the delicate balance between catering to current users and preparing for a vaguely defined and distant moment.
Antoine Riard, a prolific Lightning network developer who raised concerns about the Lightning network’s flawed security assumptions back in October 2023 (and immediately quit the project due to realizing that the issue needs a base layer patch), was Fiatjaf’s preferred example to highlight why Bitcoin’s most popular layer two has failed and deserves to get abandoned for more pragmatic designs.
Sidechains, Miners, and the Evolution of Bitcoin
Fiatjaf and I also delved into the role of miners, the activation of soft forks, and the potential of sidechains. Fiatjaf expressed skepticism that adding multiple pegged sidechains after activating BIP300 would affect sovereign full node operators – as they can optionally validate whichever chain they want and no other rule about the base layer gets changed. He argued that some of the concerns are blown out of proportion.
Nostr’s Evolution and Zaps
Fiatjaf is not a fan of zaps – at least not through the Lightning network. Based on his experience as a developer of LNBits, Zeus, Alby, and lntxbot, he advises other Nostr contributors to discontinue support for Lightning and focus on censorship resistance. His biggest concern is that users rely too much on custodial wallets, send small BTC amounts to each other that make no sense in the context of a peg-out due to the existing dust limit, and cause some Lightning nodes to crash.
Therefore, Fiatjaf’s recommendation is to forget about Lightning network entirely and focus on better tech which enables much better self-custody primitives and scales better for microtransactions.
The Future of Code Collaboration and the Vision of Nostr
As our conversation wound down, Fiatjaf shared his excitement about Wikistr: a Wikipedia client for Nostr that promises a more democratic approach to information, in which multiple articles featuring opposing points of view are allowed and encouraged. He also discussed his vision for replacing centralized platforms like GitHub with decentralized tools, allowing for a more collaborative and open-source environment.
