Secretarium is a platform that provides data integrity and verifiable transparency for sensitive computing processes. The system uses Trusted Execution Environments (TEEs) to create secure enclaves where data and processes are isolated from external tampering. The platform employs remote attestation to verify that computations occur within secure environments and provides cryptographic proof that systems and operations remain uncompromised. This allows stakeholders to validate platform security even in distributed or untrusted infrastructures. Distributed Ledger Technology (DLT) creates an immutable record of every computation and data transaction, enabling stakeholders to trace decisions and processes throughout their lifecycle. Each action is transparently logged to provide a comprehensive audit trail. The platform uses Merkle Patricia Trie (MPT) structures to provide cryptographic evidence of data integrity. This ensures that unauthorized data changes are immediately detectable, as tampering alters the cryptographic hash at the tree's root. The system is designed for compliance-heavy industries including financial services, healthcare, and legal organizations where data integrity, auditability, and regulatory compliance are required. The platform provides tamperproof records and enables independent verification of data, code, and computing processes.
