Most people encounter Bitcoin through price, politics, or curiosity. Dave Lund came to it through structure — through the realization that Bitcoin’s difficulty adjustment behaves less like a man-made system and more like a law of nature.
That conviction led him deep into Lightning, where he saw not just a payments rail, but the foundation for a new financial architecture: one where Bitcoin can stay in self-custody, move at internet speed, and generate native yield.
In this conversation, Lund unpacks the philosophy and strategy behind Flowrate, Lightning Treasuries, and OpenArk, explains why most companies are still unprepared for what Bitcoin treasury management will become, and makes the case that the next great competition in Bitcoin won’t be over price targets — but over yield per sat.
- Most people stumble into Bitcoin — and then there’s a moment where it stops being a curiosity and starts becoming a conviction. What was that moment for you, and what did it cost you to truly believe it?
For me it was the difficulty adjustment. The way Bitcoin keeps its issuance steady no matter how much computing power or energy you throw at it — that reminded me of how biology works. Living systems balance themselves under pressure. Once I saw that, Bitcoin stopped feeling like software and started feeling like something closer to a law of nature. 
It really clicked when I went deep on Lightning. Lightning answers two questions most people treat as separate: how do I earn rent on my Bitcoin without giving it to a custodian, and how do I pay for a coffee. Same protocol solves both. The cost was years I could have spent building in industries with faster paydays. But once you see it, you can’t build anywhere else.
- Lightning is still misunderstood — even inside the Bitcoin world. Why did you bet your builder energy on it, and what do most people get wrong about where it’s actually headed?
Most Bitcoiners are still in waiting mode — waiting for fiat to break, waiting for the next halving, waiting for the price to prove them right. But the price going up because of speculation or money printing isn’t the real win. Making Bitcoin actually useful is the win. Lightning is where that work happens.
What people get wrong is the timing. Lightning today looks a lot like Bitcoin mining did in the early days: messy, scrappy, full of small operators about to get professionalized. The money, the tools, the institutional setup — it’s all showing up now. Anyone who still thinks Lightning is niche is looking at a picture from three years ago.
- You’re running three interconnected projects — Flowrate, Lightning Treasuries, and OpenArk. Walk me through how they fit together in your mind. Are they three doors to the same room, or are they three different rooms running in parallel?
Same room, different doors. Flowrate runs the Lightning side. We manage liquidity for big companies — their Bitcoin, our nodes, their custody. They keep their keys, we make their Bitcoin productive. The yield comes from two simple sources: routing fees and liquidity leasing fees.
OpenArk does the same thing for the next protocol — Ark. Treasuries provide liquidity to Ark servers through multisig and earn yield on it. We orchestrate those deals.
Lightning Treasuries is the public reporting piece. Right now there’s no one place to see which treasuries are actually earning native yield. If companies are going to compete on this, the market needs a scoreboard.
- Companies sitting on Bitcoin are still largely paralysed — they hold, they HODL, but they don’t deploy. What’s the real fear stopping treasuries from earning native yield on Lightning, and why is now the moment that changes?
Two reasons.
First, they don’t know enough about Lightning. The gap between a public-company CFO and a Bitcoin maxi running a node from his basement is huge. That’s a fixable problem, and it’s why Flowrate exists.
Second, security — and that fear is fair. Lightning’s security today isn’t where it needs to be for big institutional money. We’re working on that with auditable secure elements and a project with VLS to add multisig support directly into Lightning. That last piece is a big deal.
Why now? The premium public Bitcoin treasury companies have been trading at is shrinking. Once it’s gone, the next question comes fast: what does this Bitcoin actually earn? Treasuries that can say “native yield on Lightning, no custodian” win the next cycle. The ones just sitting on coins don’t.
- Building in Bitcoin is not glamorous — the cycles are brutal, the critics are loud, and ‘yield on Lightning’ is still a hard sell to CFOs. What’s the hardest thing about what you’re doing that you never say out loud?
Right now digital credit is getting almost all the attention in institutional Bitcoin — and it shouldn’t be. That playbook only works (for now) for the top.. maybe five(?) treasuries with strong access to public markets. It doesn’t work for the next five hundred.
In a few quarters most treasuries are going to look at their balance sheet, see the premium gone, and realize they need a different strategy — one where their Bitcoin actually earns. We’re building for that moment. The hard part is being early to it and watching everyone chase the louder story in the meantime.
- When Flowrate works exactly as you dream it, what does the world look like five – ten years from now because you built it?
In ten years, the biggest payment processors are all on Lightning (the Bitcoin exchanges are already there) — and most of them got there without ever building their own routing infrastructure. They plug into Lightning Service Providers instead. They focus on their product; we make sure the liquidity is there.
Lightning has passed Visa and Mastercard on transaction volume — that’s an eight-to-ten-year curve and it’s already on track. Stablecoins use Lightning to move between chains. Every serious Bitcoin treasury is deployed across Lightning and Ark, and they don’t compete on price targets anymore — they compete on yield per sat (flow rate).
That’s the world I’m building toward. And nobody has to give up their keys to get there.
