Open Source immudb Immutable Database Reaches Widespread Adoption

Available on Amazon Web Services, Elestio, and used by India’s Ministry of Housing and Urban Affairs

Codenotary today announced widespread adoption of immudb, the first and only open source enterprise-class database with data immutability at scale, by large and small organizations, and cloud service providers. With the tamper-proof database, no data can be compromised – existing records can be updated, but never changed or deleted so there is always a history for tracking.

“immudb has grown very rapidly to be the de-facto standard for immutable storing of critical data”

Following the release of immudb 1.3 last month, Codenotary has seen increased adoption in financial services, government, military, eCommerce, primarily. In thousands of production deployments, immudb automatically stores the data versioned, timestamped and provides a cryptographic guarantee of zero tampering.

“immudb has grown very rapidly to be the de-facto standard for immutable storing of critical data,” said Moshe Bar, chief executive officer, Codenotary. “Now, we see immudb in daily use on all continents, across all industries. And, the number of stars on GitHub has more than doubled over the past year as testimony to the growing popularity of immudb.”

Unlike other databases, immudb is built on a zero-trust model: history is preserved and can’t be changed. Data in immudb comes with cryptographic verification at every transaction to ensure there is no tampering possible. immudb can be deployed in cluster configurations for demanding applications that require high scalability, up to billions of transactions per day, and high availability.

The support of both key/value and SQL makes it simple to use immudb in new and existing applications. Support for Amazon’s S3 storage cloud provides immudb with virtually unlimited data storage capacity. With immudb, organizations can travel back and forth in time and see the change history of their data. Codenotary named this the Time Travel feature of immudb.

“immudb is a great open-source alternative to blockchains and other ledger technologies,” said Joseph Benguira, chief technology officer, Elestio in a blog post. “Unlike these (blockchains and other ledger technologies), immudb can handle millions of transactions per second.”

Elestio is a managed open-source software services provider that extended the existing offering of 16 different database types, with the only tamper-proof database option, immudb.

Also, immudb is available on Amazon Web Services and accessible through the AWS Marketplace.

In India, the Ministry of Housing and Urban Affairs is using immudb as part of its India Urban Data Exchange (IUDX) project to provide a platform to help with planning for growth in cities. Some examples of sharing include location data for buses, IoT sensor data for various monitoring tasks, and crowd-sourced issue reporting data.

immudb is capable of protecting sensitive data for workloads that require the utmost in security. Codenotary uses immudb to underpin its software supply chain security product. There have been more than 15 million downloads of immudb so far. More information can be found here and the software can be downloaded here.

Use Case - Tamper-resistant Clinical Trials


Blockchain PoCs were unsuccessful due to complexity and lack of developers.

Still the goal of data immutability as well as client verification is a crucial. Furthermore, the system needs to be easy to use and operate (allowing backup, maintenance windows aso.).


immudb is running in different datacenters across the globe. All clinical trial information is stored in immudb either as transactions or the pdf documents as a whole.

Having that single source of truth with versioned, timestamped, and cryptographically verifiable records, enables a whole new way of transparency and trust.

Use Case - Finance


Store the source data, the decision and the rule base for financial support from governments timestamped, verifiable.

A very important functionality is the ability to compare the historic decision (based on the past rulebase) with the rulebase at a different date. Fully cryptographic verifiable Time Travel queries are required to be able to achieve that comparison.


While the source data, rulebase and the documented decision are stored in verifiable Blobs in immudb, the transaction is stored using the relational layer of immudb.

That allows the use of immudb’s time travel capabilities to retrieve verified historic data and recalculate with the most recent rulebase.

Use Case - eCommerce and NFT marketplace


No matter if it’s an eCommerce platform or NFT marketplace, the goals are similar:

  • High amount of transactions (potentially millions a second)
  • Ability to read and write multiple records within one transaction
  • prevent overwrite or updates on transactions
  • comply with regulations (PCI, GDPR, …)


immudb is typically scaled out using Hyperscaler (i. e. AWS, Google Cloud, Microsoft Azure) distributed across the Globe. Auditors are also distributed to track the verification proof over time. Additionally, the shop or marketplace applications store immudb cryptographic state information. That high level of integrity and tamper-evidence while maintaining a very high transaction speed is key for companies to chose immudb.

Use Case - IoT Sensor Data


IoT sensor data received by devices collecting environment data needs to be stored locally in a cryptographically verifiable manner until the data is transferred to a central datacenter. The data integrity needs to be verifiable at any given point in time and while in transit.


immudb runs embedded on the IoT device itself and is consistently audited by external probes. The data transfer to audit is minimal and works even with minimum bandwidth and unreliable connections.

Whenever the IoT devices are connected to a high bandwidth, the data transfer happens to a data center (large immudb deployment) and the source and destination date integrity is fully verified.

Use Case - DevOps Evidence


CI/CD and application build logs need to be stored auditable and tamper-evident.
A very high Performance is required as the system should not slow down any build process.
Scalability is key as billions of artifacts are expected within the next years.
Next to a possibility of integrity validation, data needs to be retrievable by pipeline job id or digital asset checksum.


As part of the CI/CD audit functionality, data is stored within immudb using the Key/Value functionality. Key is either the CI/CD job id (i. e. Jenkins or GitLab) or the checksum of the resulting build or container image.
