First Principles Ep. 6 with Shafi Goldwasser What if you could prove something is true without revealing why it’s true? Turing Award winner Shafi Goldwasser tells the origin story of zero-knowledge proofs: how a playful question about playing poker securely over the telephone led her, Silvio Micali, and Charles Rackoff to rethink what a mathematical proof could be. Goldwasser traces those ideas through interactive proofs, the sum-check protocol, SNARKs, and the systems now used to verify computation and preserve privacy on blockchains. She also reflects on why breakthrough ideas are often rejected at first, how toy problems can produce foundational theories, and whether AI systems should have to prove their answers. Hosted by Tim Roughgarden with Justin Thaler 00:00 Intro 03:36 How mental poker inspired zero-knowledge proofs: Proving that something is true without revealing the underlying information 06:30 The simulation paradigm and the meaning of “zero knowledge” 08:33 Why the original paper was repeatedly rejected 10:33 How interactive proofs became more powerful than conventional proofs 13:36 The road to modern SNARKs 19:02 Why the sum-check protocol is so useful for verifiable computation 25:31 Why many so-called “zk proofs” are not actually zero knowledge 34:06 Why toy examples, playfulness, and narratives can produce deep theory 37:23 The role of rigor and computational assumptions in cryptography 42:44 Applying zero-knowledge proofs to law, evidence, and secret software 45:23 Training AI systems to provide proofs alongside their answers 54:27 Why genuinely new ideas are often difficult for experts to recognize

BITCOIN RAILS #69: ZERO-KNOWLEDGE PROOFS FOR POST-QUANTUM BITCOIN | with Benedikt Bünz 🔗 YOUTUBE: 🌿 SPOTIFY: While many Bitcoiners remain hopeful the network will embrace zero-knowledge proofs for protocol-level use cases, practical adoption has remained limited outside of BitVM and a handful of experimental proposals. Most of the world’s ZKP research has circled around Ethereum and other ecosystems, where significant resources have been dedicated to advancing these systems, particularly for scaling and privacy applications. One of the most notable contributors to this research is Benedikt Bünz ☕️ — professor of cryptography at NYU and collaborator of Dan Boneh, who together inarguably form one of the strongest blockchain-applied cryptography teams in the world. The pair recently announced they’ll be leading the new post-quantum cryptography unit localhost research — the first dedicated PQ research effort within a major Bitcoin development organization. With Benedikt leading the charge on the use of zero-knowledge proofs for post-quantum mitigation, the question emerges: will the post-quantum transition be the catalyst to finally bring zero-knowledge proofs to Bitcoin's core protocol? In more detail, Benedikt and I discuss: - Why ZKPs haven’t been widely adopted by the Bitcoin technical community — and why the threat of quantum computers may change that posture going forward - How ZKPs could be used for signature batching to address larger post-quantum signatures in Bitcoin’s post-quantum era - Why Bitcoiners will likely prioritize hash-based signatures as an initial post-quantum scheme — rather than more efficient but less proven alternatives (e.g., lattice-based) - How ZKPs have evolved over the last decade and may finally be ready for Bitcoin’s strict requirements around trust assumptions - Why Benedikt and Dan are teaming up with localhost research to create the first post-quantum cryptography unit within a major Bitcoin development organization + what they hope to accomplish This episode of Bitcoin Rails is brought to you by: LayerTwo Labs LayerTwo Labs — developing research, software, and technologies for scaling Bitcoin via the integration of Drivechains (BIP 300/301) Hashi on Sui — a primitive for executing Bitcoin DeFi transactions, without having to trust a federated bridge or other centralized entity BitBox BitBox — an open-source Bitcoin-only hardware wallet, with smooth UX and no compromises on security.

"As you realized, there was no money lost. And this is by design." Kostas Chalkias (Kostas Kryptos) is co-founder and Chief Cryptographer of Mysten Labs, the team behind Sui. When the network halted, he was in the war room. This is his breakdown of what actually happened. "The ideal option is to halt, compared to just losing money if something else happens." We cover: — Why halting the network was a deliberate design choice, not a failure — What was really going on behind the scenes while crypto Twitter panicked — The global war room: 50+ people across Europe and the US working through the night — Why a decentralized network recovers differently than one company flipping a switch — "Move fast and break things", why the Facebook motto is exactly wrong for money — Why Kostas believes most other blockchains wouldn't have recovered in days — Where the line sits between an honest edge case and a broken system — What the outage proved about how Sui is actually built Thanks to Kostas for coming on New Era Finance Podcast. Highlights: 00:00 — Intro 00:43 — What Happened During The Outage 03:45 — Why Halting Was The Right Call 05:30 — Inside The War Room 08:00 — Why Decentralized Recovery Takes Longer 11:00 — The Lessons That Made Sui Stronger 14:30 — Why AI Agents Are The Real Users Of Crypto 19:00 — Free Stablecoin Payments vs Bank Fees 23:00 — Own And Monetize Your Own Data 27:00 — Why A Fast Layer-1 Changes Everything

ZKForge V1 is now live and the source code is public on GitHub: Visit: Users can sign up, log in, and chat privately using zero-knowledge authentication (ZK-STARK) with full end-to-end encryption and non-custodial wallet integration. No passwords, no stored private keys, all encryption and identity verification happen locally on the user’s device. Core Features • Zero-Knowledge Authentication (ZKAuth) Users sign up and log in using a locally generated Ed25519 keypair. Authentication uses zero-knowledge proofs (ZK-STARK-compatible), proving identity ownership without revealing the secret key. The backend never sees or stores private keys , only the derived public key and Solana address. • End-to-End Chat Encryption Every conversation is encrypted with per-room symmetric keys (nacl.secretbox AES-grade security). Keys are sealed and exchanged using ephemeral Curve25519 boxes derived from each user’s Ed25519 keypair. Messages are signed for sender authenticity. The server cannot decrypt messages; all encryption happens client-side. • Global Lounge (Public Encrypted Room) Encrypted public discussion room using a temporary shared key. Messages self-destruct after a defined time window. Rate-limit and anti-spam protections are enforced through Supabase RLS policies. • Wallet Integration (Non-Custodial) Each user derives a Solana wallet from their zero-knowledge secret. Private keys are generated and stored locally, never sent to the backend. Supports in-app USDC transactions signed locally. • WebSocket-Based Real-Time Updates Secure WebSocket channel for live message delivery, typing indicators, and presence tracking. Each message includes cryptographic nonce, ciphertext, and signature validation before render. Architecture Overview Frontend (React + Tailwind): Encryption, proof generation, local key storage, message rendering. Backend (Express + Supabase): Stateless API for sessions, rate limits, and metadata. Crypto Layer (tweetnacl, ed2curve, bs58): Signing, sealing, encryption primitives. Database (Supabase PostgreSQL): Stores ciphertext and public keys only. Realtime (WebSocket): Delivers encrypted payloads instantly. Key Design Principles Zero Storage of Private Keys All signing keys exist only in the user’s local storage. Provable Authentication Login requests include cryptographic proofs verified without revealing secrets. Encrypted-At-Rest and In-Transit All messages are encrypted before leaving the device. Verifiable Sender Identity Each message includes a detached Ed25519 signature verifying authorship. Tech Stack Frontend: React, TailwindCSS, TypeScript, Vite Backend: Node.js (Express), Supabase, MongoDB Cryptography: TweetNaCl, ed2curve, bs58, genSTARK Blockchain: Solana Web3.js Realtime: WebSockets Security: Row-Level Security, JWT Sessions, Proof Verification What’s next x402 protocol implementation

Joe Rogan just said what nobody in finance wants to hear about quantum computing. Rogan: “It’s over. Like there’s no privacy.” He’s not being hyperbolic. He’s being early. Every dollar in every bank account on Earth is protected by one thing. Math. Not vaults. Not guards. Not governments. Math problems that current computers can’t solve fast enough to break. That’s it. RSA encryption. Elliptic curve cryptography. The same math guarding your savings account guards sovereign wealth funds. Defense networks. Nuclear launch protocols. Quantum computing doesn’t pick the lock. It removes the door. A quantum system at sufficient scale breaks RSA encryption in hours. The same problem would take a classical computer longer than the age of the universe. This isn’t theoretical. Google, IBM, and China are racing toward fault-tolerant quantum systems. The timeline isn’t a century. It’s a decade. Maybe less. Rogan: “I think the real problem is the financial market. It’s all numbers, right? It’s all just ones and zeros.” He’s right. And it’s worse than he thinks. The first entity to reach that threshold doesn’t gain an advantage. They gain access. Every encrypted financial transaction ever recorded. Every classified document. Every crypto wallet. Every private key. Every medical record. Every secret ever sent over a wire becomes a postcard. China holds more quantum computing patents than any nation on Earth. Their research runs without public oversight or shareholder pressure. They’ve been harvesting encrypted Western data for years. Intelligence agencies have a name for the strategy. Harvest now, decrypt later. Rogan: “If somebody controls that before we do, if somebody breaks through with this type of technology and then just shuts all the other ones off.” If a foreign power achieves this before post-quantum encryption is deployed, there is no countermove. You can’t un-read stolen data. You can’t restore trust in a system whose entire security model became fiction overnight. People talk about AI as the defining technology of the century. They might be wrong. AI needs data and compute and infrastructure to be dangerous. Quantum computing just needs to exist. One breakthrough. One machine. One moment where the math that protects everything stops being hard enough. Most people heard Rogan and thought exaggeration. The ones paying attention heard a countdown. We built the entire modern world on one assumption. That certain math problems would stay unsolvable forever. Nobody promised us that.

Ep. 16 | Free The Money | Zcash & ZODL: Why Encryption Wins in an AI Driven World In this episode, I’m joined by Tony Margarit 🛡 , former Finance & Ops at the Electric Coin Company (ECC), the original team behind Zcash 🛡️ and the Zashi wallet. Tony breaks down what’s happening inside the Zcash ecosystem, why the former ECC team launched Zcash Open Development Lab, and what they’re building now with their newly rebranded wallet, Zodl (fka Zashi). We talk about the bigger mission: making privacy normal and scaling private digital cash to billions. Tony explains why Zcash isn’t “corporate controlled,” and how decentralized development actually works across multiple teams and contributors. We also discuss Tachyon, a major upcoming upgrade designed to dramatically improve Zcash’s scalability and prepare the network for billions of users. We get into the product leap that matters most for real adoption: world-class UX + real utility. Tony explains Near Intents and why it’s a major unlock, enabling more seamless swaps across ecosystems so users can keep value encrypted while still interacting with other assets. Tony also explains CrossPay as a key bridge to adoption: the ability to pay friends or vendors in the currency they want while keeping your own holdings private. We cover why Zcash still supports transparent transactions, how that helps with exchange access and adoption without weakening shielded privacy, and why Ledger/Trezor shielded support could be a major catalyst for growing the shielded pool. Finally, we go deep on the AI angle — blockchain surveillance, wallet deanonymization, and why encryption (not just obfuscation) matters as AI gets more powerful. We wrap with how zero-knowledge proofs could reshape identity, governance, and everyday verification online. Sign up for ITrustCapital with this link for $100 funding bonus.

Picture this: you have a driver's license in your wallet. When someone needs to check your age, you just pull it out. You don't have to call the DMV and ask permission first. Now imagine trying to do that same thing online. Today, every time you need to prove something about yourself digitally - your age, your identity, that you're a real person - you have to go through some company's server. Google's. Facebook's. Some random third party that now has all your data. And here's the worse part: those systems don't talk to each other. The government ID system can't talk to your bank. Your bank can't talk to new stuff like crypto payments. Everything is siloed. If you want AI agents to pay for things on your behalf? Forget it. Nothing connects. So Evin McMullen evin, Billions Network co-founder and CEO, asked: why can't your digital identity work like your physical wallet? Your government already signed your passport. That signature is tamper-proof. What if you could generate zero-knowledge proofs straight from your device - proving you're over 18 without revealing your birthdate, proving you're human without exposing who you are? No middleman. No surveillance. No permission needed. Just pull out your proof whenever you want, like pulling out your driver's license. That's what Billions Network built with institutions like the European Commission and government systems. W3C open standards that connect everything: government ID systems, blockchain payment rails for AI agents, legacy infrastructure. One signature. Infinite proofs. Your device. Video clip from #TheBraveTechnologist podcast episode 106 with Evin hosted by LukΞ Mulks 🦁⟁◎⟁ 🙏
