Sofia, Bulgaria – BRAIN++ AI Factory announces CHAIN++: a federated, permissioned data governance chain designed to solve a critical challenge in AI-sharing sensitive datasets securely and legally.
Today, promising AI collaborations are routinely stalled by compliance risks. Traditional paper contracts and standard database logs cannot technically guarantee what happens to data once it leaves an organization’s perimeter.
CHAIN++ changes that. Co-funded by the EuroHPC Joint Undertaking and the European Union, this innovative technology provides absolute data sovereignty and mathematical trust between organizations. In line with our commitment to collaborative innovation, CHAIN++ is being developed to be fully open source upon its official production release.
How it Works: Security at Every Layer
Built directly within our ecosystem at Sofia Tech Park, CHAIN++ coordinates data sharing across independent AI infrastructure networks through three secure layers:
- Cryptographic Smart Contracts: Usage constraints – such as data residency, expiration windows, and specific processing limits – are locked cryptographically on a multi-factory federated chain where records cannot be retroactively modified.
- The Data Guardian: A local, client-side application that scans and auto-classifies outgoing data, immediately blocking any transfer that violates contract terms before it ever leaves your infrastructure.
- Tamper-Evident Audit Trails: Utilizing kernel-level eBPF logging, every single file execution, data access, and container action is stamped with a cryptographic fingerprint, giving compliance teams undeniable proof of regulatory alignment (GDPR, EU AI Act, EHDS).
Engineered for Regulated Industries
CHAIN++ is built specifically to address high-stakes data environments:
- Healthcare & Life Sciences: Securing clinical registries for collaborative research.
- Financial Services: Enabling fraud detection model training without exposing raw consumer transaction logs.
- Public Sector: Driving secure cross-institutional infrastructure projects.
What’s Next?
Our current PoC represents an important internal milestone. The next defined step in our roadmap is the public release of the underlying codebase as open-source on GitLab. Once available, this release will enable the developer and compliance community to explore, audit, and contribute to this new standard for federated AI data trust.
