Codenotary releases open-source immudb 1.11, embedding tamper-proof audit logging and PostgreSQL compatibility to deliver verifiable data trust and simplified compliance.
Codenotary has launched immudb 1.11, a major update to its open-source database that advances it from a tamper-proof datastore into a full trust infrastructure layer.
The release introduces immutable audit logging built directly into immudb, enabling organisations to create permanent, tamper-proof records of both data and database activity, including who accessed or modified data and when.
Built on cryptographic verification, immudb ensures that neither data nor its history can be altered or deleted without detection. This architectural shift removes the need for external logging tools, consolidating all records within a single system and eliminating risks associated with fragmented or modifiable logs.
The update also delivers compatibility with PostgreSQL, allowing existing applications and tools to run unchanged while gaining built-in immutability and auditability. This lowers migration barriers and expands adoption across enterprise environments.
For organisations, the result is unalterable audit trails, simplified compliance and reporting, and reduced operational complexity. By embedding auditability as a native capability, immudb positions open source as a credible alternative to proprietary compliance and logging systems.
“The new immudb focuses on a problem many organizations struggle with: proving that their data – and the actions taken on it – can be trusted,” said Dennis Zimmer, Co-founder and Chief Technology Officer, Codenotary. “While most systems rely on separate logging tools to track changes, those logs can be incomplete, disconnected, or even altered.”
With this release, open source strengthens its role in security-critical infrastructure, enabling verifiable trust across AI systems, cybersecurity, and supply chain environments.
