# Virtue (VirtuE Deep-Tech) > Virtue builds human-centered AI: EDAA™ affective computing, Liquid Ethics, and DCA (Deductive Causal Architecture), a sovereign causal-computing layer that lets governments, institutions and companies own, audit and scale the intelligence they create. Key facts: - DCA (Deductive Causal Architecture) adds dedicated, hardware-encrypted causal computing to the data center. It reasons through cause and consequence in inspectable steps around an ontology of human intent, instead of relying on statistical correlation alone. - DCA is deployed with data centers, which offer centralized or decentralized AI systems to governments and companies, configured with in-country partners. Each organization keeps a private, auditable model of its own operations and scales at a deterministic cost. - EDAA™ is Virtue's affective computing engine: it interprets behavioral and environmental cues so AI products can respond to human emotion and context. - DCA powers the OWN Experiences ecosystem (https://ownexperiences.com/). - Contact: marketing@virtuedeep.tech ## DCA - [DCA Tech Memo](https://dca.virtuedeep.tech/): DCA as Layer Zero, the technical memo - [Technical documentation](https://documentation.virtuedeep.tech/): architecture and integration documentation ## Website - [Home](https://virtuedeep.tech/): overview of Virtue, affective computing, DCA and FAQ - [EDAA™ - Build your solution](https://virtuedeep.tech/virtue-build-your-solution/): adding affective sensitivity to data-driven products - [Solutions](https://virtuedeep.tech/safety-security-human-digital/): vSense (customer experience), vSafe (operational safety and security), vEd (education) - [Ethical AI](https://virtuedeep.tech/ethical-ai/): Liquid Ethics, privacy and responsible AI ## Related - [OWN Experiences](https://ownexperiences.com/): the human-centered ecosystem powered by DCA
