Privacy and AI are becoming the hottest combo in crypto right now. There's an interesting play happening on Solana: AIJ token connects to AIJack, a legit open-source project focused on ML security and privacy. The project has picked up decent traction—over 400 GitHub stars and already deployed in more than 10 production environments. What makes it stand out is the practical angle: it's built as a simulator to stress-test machine learning models against security vulnerabilities and privacy risks. Given how much AI infrastructure is moving on-chain these days, this kind of security tooling could matter. Whether it becomes something real or just another hype cycle, the intersection of AI privacy and blockchain is definitely where builders are focusing attention.
