Proof-of-Useful-Work proposes that the same GPU computation used for AI workloads can also secure a blockchain network. But that immediately triggers an economic objection - if miners are already getting paid for running AI jobs, does the security of the network collapse? Rafael Pass breaks it down and shows...

@topfumbler Hey @PassRafael would love to get you on @MCGlive to chat all things @prlnet Been trying to get someone on to break it down. Shoot me a dm, yours are off 🫡

economic objections aside, PoWW is an intriguing concept. Could align AI compute with blockchain security if done thoughtfully. But a lot would depend on how the system was designed to prevent abuses.

Pearl started with a simple question: Why should AI and blockchain mining compete for the same GPUs when the same computation could do both? In this talk, Pearl co-founder Ilan Komargodski explains how that idea became a live proof-of-useful-work network turning AI inference into blockchain security with minimal overhead.

What if mining didn’t just secure the network, what if it made it better? That’s PoW 2.0 (Proof of Useful Work). More miners → better UX → more users → stronger network. Psy Protocol turns computation into progress. PoW, evolved.

Proof of work has always demanded a brutal trade-off - to secure a monetary network, you burn energy on the scale of entire countries. Meanwhile, hundreds of billions poured into AI - all for one operation at massive scale - matrix multiplication. For years, these energy markets were disjoint. It was commonly believed that proof of work could never be implemented on top of real-world instances. They were wrong. The same matrix multiplication that powers AI can secure a monetary network as a by-product - every GPU cycle doing double duty. A currency backed by the most valuable computation on earth. A deep dive by Omri Weinstein ⤵️

Proof-of-Useful-Work forced us to solve a problem ordinary blockchains do not have. A Pearl miner performs large matrix multiplications as part of a real AI workload. Naively, when it finds a valid block, it would need to publish those matrices so the network could verify the computation. The matrices may contain private model data or user information, and a single weight matrix can be tens-to-hundreds of megabytes. Publishing them on-chain would be both prohibitively expensive and a privacy risk. This is why we encapsulated the entire mining computation inside a zk-SNARK. A zk-SNARK can take an arbitrarily complex computation and compress it into a small cryptographic proof. The proof reveals nothing about the underlying matrices, while still allowing the network to verify that the miner found a valid block. Instead of placing tens-to-hundreds of megabytes of potentially sensitive data on-chain, Pearl miners publish a zero-knowledge proof of roughly 60 kilobytes. The blockchain verifies the useful computation without ever seeing the model weights, activations or private data behind it. This is what makes Proof-of-Useful-Work practical at scale: large AI computations happen off-chain, while only a compact, privacy-preserving proof reaches consensus.

Karlsen Network Stage 2 is Coming!🚀 At #Karlsen Network, we believe in building the future with integrity and dedication. That’s why we’ve spent months actively developing this major update, ensuring it’s built on solid ground before sharing it with the world. We’re thrilled to reveal that we now have our first results—and they’re set to seriously redefine our roadmap. We’re proud to introduce Network Stage 2, a transformative update that will reshape how computational power is used across the network. With Proof of Useful Work (#PoUW), miners can now perform real-world computations alongside block proof of work, unlocking new earning potential and revolutionizing #GPU usage. With this we celebrate our 1 year anniversary🎂, thank you for your continued trust and support. Together, we’re not just building a network; we’re shaping the future. Enjoy the video!📽 Karlsen Network $KLS

Who still believes in Proof of Work? ✋ At the Skyline PoW Mixer, our founder Carter (Carter Feldman) explained its importance and revival. Proof of Work embodies freedom, not just block mining. Anyone can participate without permission, gatekeepers, or censorship. Psy Protocol advances this with PoW 2.0: Proof of Useful Work. Instead of wasting energy, computation is purposeful. ZK math verifies everything. Miners earn for contributing to real, measurable work that strengthens the network. It’s open-source, censorship-resistant, and built for the next internet. The future belongs to builders, users and decentralization believers. The king is coming home.

AI has two sides: the applications that need intelligence, and the computers that provide it. OptimAI Router brings them closer together. For developers: access a growing range of open AI models through one connection. For node operators: turn your computer into a potential source of AI inference, contributing computing resources to real workloads across the network. One side brings the demand. The other brings the capacity. OptimAI connects them. We're building toward an AI network where developers can access diverse models, more computing resources can participate, and intelligence isn't tied to a single provider. Build with open models. Contribute computing power. Help grow the network. One network. From AI requests to distributed compute. OptimAI Router. Coming soon. ⚡

David Friedberg: “Why don't we let AI models get bar certified and get medically certified?” “So if the AI models, it turns out, are actually proving to be more accurate, more thoughtful, more responsive, more reasonable, whatever metric we're using, and they pass the same criteria as one would need to pass to qualify for the bar, or to qualify for a doctor certificate, why don't we do that for the AI?” “If that then happens, then the same privilege accrues to the AI as it does to the individual human that does it.” “And now, if you extrapolate from where that takes us, if we're suddenly giving AI the same sort of privileged rights that we give to privileged humans, where's that gonna take us ultimately with respect to the overall rights for AI?”
