TouchBrick, a DePIN for protecting the privacy of sensitive enterprise AI training data, is building on Peaq. TouchBrick's AI agents, named Sentinels, allow companies to train their AI models using the most sensitive user data, while maintaining privacy, and complying with global regulation frameworks such as GDPR. TouchBrick's Sentinel Machines will leverage peaq IDs for the management of identities and authorization, and exchange the encrypted hashes of training data using the Peaq messaging protocol.
