Agenda

• 16:30–16:45 — Networking

• 17:00–17:45 — Socratic Seminar
• 17:45–18:15 — Demos & Startup Showcase (incl. closing demo — Sonar → preview Builders Turin 2)

A participatory afternoon: bring questions, jump into the discussion, and share what you're building — or what you're stuck on. Plenty of Q&A throughout.

Intro

• Chatham House Rules — no photos/video
• First Builders Turin! 10-second intros: name · what you do · what you want out of it

Socratic Seminar

Lightning: reliability & the mobile problem

• Matt Corallo: 99% payment success is unacceptable — LN is far better than that
• LDK: async payments fix receiving on mobile
• Breez SDK "Class of Q2 2026" — instant bitcoin in every app

Open source: control vs. cost

• Corallo: open source is about control, not customizability
• Xiaoyin Qu: "Open source will win AI — because it's cheaper"
• GitHub killed our CI mid-release + banned twice "by mistake" — FOSS infra risk

Quick hits: mining & dev tooling

• First StratumV2 block (GoMining / DMND_Sv2)
• Fable 5 / Claude dev-tooling

Local spotlight

• Vincenzo: CLN plugin manager / Coffee plugin in Core Lightning
• BLOX, Piazza Solferino — a Torino hub
