GM CT ☀️ Decentralized finance protocols are sitting on a hidden risk surface that smart contract audits never catch. I spent years reviewing audited DeFi codebases that still rely entirely on classical ECDSA signature verification. @quipnetwork allows automated market makers and lending vaults to integrate post-quantum verification at the contract level. Protocols can authenticate high-value pool settlements through quantum-resistant signature schemes. Zero protocol refactoring. Total systemic insulation. Security audits are meaningless if the signature scheme itself becomes mathematically broken.

Google cut Bitcoin’s quantum deadline to three years. Their March research paper found breaking Bitcoin’s elliptic curve cryptography takes about 500,000 qubits. Not the 10 million everyone assumed. Google’s target for full post-quantum migration: 2029. I’ve been working on post-quantum security since 2019. Almost nobody outside a narrow group takes this seriously yet. For my business, that’s an edge.

Good night everyone 🌙 A machine doesn't have to be doing something right now to have value. There's a lot of computing capacity sitting idle across the world, while demand for compute keeps growing. The interesting question is whether those unused resources can become productive participants in a larger network. That's one reason @quipnetwork caught my attention. Instead of thinking about compute as something that belongs to a single machine or provider, Quip explores a model where available resources can contribute to distributed workloads. Turning unused capacity into useful computation is a simple idea, but the scale of it could be much more interesting.

Bitcoin's plan to survive #QuantumComputers has reached one of the oldest disagreements in the protocol: how big a block is allowed to get. The problem they're hitting (repeatedly) is that post-quantum signatures are REALLY big. On the Delving Bitcoin forum, developers spent late July and August comparing four ways to build a quantum-resistant output type, under names that admittedly mean nothing outside the protocol: P2MR, P2TRv2, P2TRH and P2QR On a Bitcoin Core regtest run, developer jeanpablojp clocked a P2MR two-leaf spend at 513 weight units against 545 for the equivalent Taproot script path, with the design needing only about 96 lines on top of the existing Taproot code. Developer conduition points out that hash-based schemes would need an 8x jump in block size. Each year, the blockchain would grow by TERABYTES - rather than the hundreds of gigabytes it currently grows by. That is a lot of disk space to ask of anyone running a full node. Pieter Wuille, one of #Bitcoin's most senior developers, is less worried about the storage footprint. His point is that storage has always grown faster than the chain, and the real limit is validation bandwidth at the tip - where every node has to validate new blocks as fast as they arrive. On the positive side, the conversation has at least moved on to costing the #Quantum migration and choosing an approach. It's a WAY more concrete conversation than the usual ⌛quantum-will-break-Bitcoin ⌛ coverage.

Quantum computers... for video games? Just imagine, some guys actually used a QPU to build a game. Quantum Backrooms uses real QPUs to generate constantly changing mazes inside the game world. Pretty unusual approach.😉 And here’s the most interesting part - we still have no idea what else people will start using quantum technologies for once access becomes easier. That’s exactly why @quipnetwork idea of making quantum computing power more accessible feels especially interesting to me.

The Responsible Fintech Institute and crypto custody solution @Safeheron are piloting quantum-safe wallet generation and transfers on a NEAR testnet. The pilot brings banks and regulators together across jurisdictions to build post-quantum infrastructure for the whole industry.

NEAR is one of the first blockchains with quantum-safe signing live on mainnet. NEAR's first quantum-safe signature scheme, ML-DSA (Dilithium), protects user accounts and assets today. Here's what's next + the full quantum-safe roadmap 🧵

Billions of dollars currently sit exposed to quantum attacks, per Bloomberg. Most major chains have post-quantum roadmaps mapped years out. NEAR already shipped FIPS-204 post-quantum signing. Full thread:

Question for BSV miners (TAAL, GorillaPool, anyone on Teranode): We verify transparent proofs (STARKs, no trusted setup) inside Bitcoin Script on mainnet. You've already mined our 600 KB scripts and 1.6 MB unlocking scripts... it works. The catch: a proof's security is paid for in bytes, and the current policy limits (~500 KB per script, ~1 second validation) cap us at about 64-bit security. Would any of you raise the script limit to 4 MB and validation time to 5 seconds, at a higher fee rate? That gets the same proofs to 128-bit. Happy to pay for the compute. Thanks, my DMs are open.

The most paranoid people might be the nation states accumulating #Bitcoin to avoid sanctions. We can't prove a quantuk computer doesn't already exist. What we can do is use algorand with falcon signatures today...
