Polyhedra

2025 was a year we had to fight for. From zkML progress on major models, advancing ExpChain toward mainnet, and launching Ocash mainnet alpha, redefining how privacy, compliance, and AI payments can coexist. We never stopped building. 2026 will be bigger. Read full blog here. blog.polyhedra.network/polyhedra-movi…

AI can now execute full-scale cyberattacks. But that’s not the real problem. The real problem is: you no longer know what to trust. Our co-founder and CTO @Tiancheng_Xie sat down with @Tony0kai on the latest episode of Hash It Out to break down what’s actually changing — across AI security, multi-agent systems, and post-quantum infrastructure. They covered: → Why Claude Mythos completing a 32-step network attack changes the economics of cybersecurity → How AI makes attacks cheaper — but also makes defense scale the same way → Why closed-source advantages in cyber models may only last 6–12 months → The real risk in multi-agent systems: prompt injection, fake data, and loss of control → Why zero-knowledge proofs don’t stop attacks — but make systems verifiable → How post-quantum security is becoming a race to define the next internet standard As AI systems become more autonomous, the challenge isn’t just preventing attacks: It’s proving that what you’re running — your model, your data, your agents — is actually what you think it is. That’s the layer most systems still don’t have, and exactly what we’re building. 🎥 Watch the full episode: youtu.be/VPu71nFXS0o

𝗛𝗮𝘀𝗵 𝗜𝘁 𝗢𝘂𝘁 - 𝗔𝗜 𝗜𝘀 𝗕𝗿𝗲𝗮𝗸𝗶𝗻𝗴 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 You can’t write bug-free code. That’s just reality. Now add AI: → Bugs are found faster → Exploits are generated faster → Attacks scale automatically The response? → Use AI to defend → Reduce human in the loop Security is no longer human vs human. It’s AI vs AI. 👇 Taken from Hash It Out with @Tiancheng_Xie & @Tony0kai x.com/PolyhedraZK/st…

6/ As marketplaces continue to grow, trust must extend beyond storefront names and profile pages. With Polyhedra i-D, platforms can help ensure that seller accounts remain tied to real, accountable individuals. Try id.polyhedra.network

5/ That’s why we built Polyhedra i-D. Our zk-powered face verification confirms real human presence and identity consistency — without storing biometric data or exposing personal information.

1/ Online marketplaces have made it possible for anyone to become a seller. In minutes, a new storefront can appear, listing products and accepting payments from customers around the world. But as e-commerce scales, a critical question is becoming harder to answer: Who is actually behind the seller account? Here’s what’s happening 👇

A viral claim said: “Bitcoin can be cracked in 9 minutes.” TC’s take: → This is not a near-term risk → Practical quantum machines don’t exist yet → Crypto can upgrade when needed When it becomes real, the industry will move fast. 👇 Taken from Hash It Out with @Tiancheng_Xie & @Tony0kai x.com/PolyhedraZK/st…

Google disclosed a quantum vulnerability using a zero-knowledge proof. The technology they used to responsibly warn the world about the collapse of classical cryptography — is the same class of proof system our team has spent a decade building. Our co-founder and CTO @Tiancheng_Xie sat down with @Tony0kai on the first episode of Hash It Out to unpack what this means - for AI, for post-quantum security, and for the role zero-knowledge infrastructure plays in both. They covered: → Google's breakthrough and why they disclosed it via ZK → AI collapsing the economics of cybersecurity - $1.4B drained from crypto in the past year → Why verifiable computation matters more as AI models become more capable → The real timeline for post-quantum migration Zero-knowledge proofs were designed to prove truth without revealing secrets.

6/ As democratic systems explore digital voting, trust must extend beyond login credentials. With Polyhedra i-D, platforms can help ensure that every vote reflects a real individual while preserving both security and personal privacy. Try id.polyhedra.network

5/ That’s why we built Polyhedra i-D. Our zk-powered face verification can confirm that a real human is present and tied to a verified identity, without storing biometric data or exposing personal information.

1/ Voting has traditionally required one thing: physical presence. Citizens travel to polling stations, show identification, and cast their ballots in person. But as societies digitize, that model is beginning to change. Here’s what’s happening 👇 :
