Today we reached a massive milestone at Zama : bootstrapping in less than 1 milliseconds. Bootstrapping in FHE allows “cleaning” the noise in encrypted data, and is responsible for the vast majority of the computation time. Thus, the faster bootstrapping gets, the more confidential transactions per second the Zama Protocol can process. We achieved this after years of research on efficiently using GPUs for FHE. The results are MINDBLOWING: Boostrapping latency: - 2021: 53 ms - today: 0.9 ms - speedup: 56x When applied to integers arithmetics, the results are even more insane: 64 bit encrypted addition latency: - 2022: 2,000 ms - today: 8.7 ms - speedup: 230x 64 bit encrypted multiplication latency: - 2022: 13,000 ms - today: 32 ms - speedup: 400x To understand what this means in practice, lets look at confidential stablecoin transfers: - 2022: 0.1 tps - today: 230 tps - speedup: 2,300x And it’s so cheap also: about $0.0001 / transaction for a confidential stablecoin. Tldr; FHE is now FASTER than Ethereum and most L2s! And it’s only a matter of months before we can reach 1000 tps. Next steps: build an FHE ASIC to reach 100k tps by 2029. Enough to cover Visa, Mastercard and SWIFT volume combined. 🚀🚀🚀 Full post in the comments

⏳ The Hidden Bottleneck in Scaling: Data 🔥 🚀 ✨ If your platform depends on external data, your speed of scaling is gated by the speed of integrating it. Architect for that. When we launched in France we learned that scaling supplier integrations is one of the biggest growth bottlenecks. Manual scripts and per-country systems wouldn’t scale. Hence, we rethought how we scale Picnic — technically and operationally. So we asked hard questions: ❓ How do we scale supplier integrations without scaling chaos? ❓ How do we maintain data quality across borders, formats, and teams? ❓ How do we turn every market launch into a plug-and-play experience? The answer: We paused. Rethought everything. And rebuilt. What emerged was a greenfield, event-driven, microservice-powered master data integration system — robust enough to handle country-specific quirks, resilient enough to scale, and beautiful enough to make a whiteboard cry. 🧠🔥 💥 The impact? 📉 80%+ reduction in supplier onboarding effort 🌍 Full reuse across markets — no copy-paste tech debt 🚀 Enabled rapid scaling into new regions 🔁 Replaced all legacy integrations in < 1 year 💬 Set a new internal standard for platform design Read the follow story of slowing down to speed up, scaling smart, and engineering with purpose.

France is about to force millions of businesses into software. Not politely. Not gradually. By law. 📑 Starting in 2026, every French business — from the corner café to the design studio — will have to issue and receive invoices in a standard digital format. Each invoice will go automatically to the customer and to the tax authorities for VAT reporting. Think about all those shoeboxes full of receipts. The envelopes stuffed with slips. The PDFs buried in inboxes. A whole way of working disappears overnight. What a relief. 😮‍💨 For freelancers, maybe it’s just one less pile of paper on the desk. But for B2B companies, it changes everything. Because once invoices live in software, payments naturally follow. Reconciliation follows. Cash flow follows. Suddenly, accounting software isn’t just admin — it becomes the default financial hub. That’s why this will be a fierce battle for software companies. Everyone wants to be the tool SMBs pick for compliance. Because once you win invoicing, you can win everything else. But let’s be honest: there won’t be just one winner. SMBs are too diverse, too fragmented. There’s room for many players to succeed and they will. One regulation. Huge consequences. And…🍿 yes, a little drama. P.S. I’ll be at the Congrès de l’ordre des experts-comptables tomorrow, Swan’s booth #R551
