Codenotary and the SLSA Framework

Codenotary is leading the way in safeguarding against software supply chain attacks–an ever-present threat, where vulnerable artifacts can be introduced at several points. SolarWinds and other hacks have encouraged organizations, like CISA, to release guidelines to minimize the risk of such attacks and develop an industry-wide solution jointly with the commercial and open source communities.Enter …

CAS and Home Assistant: Making Sure Smart Home Are Secure Homes

When we announced the Community Attestation Service, we had a vision. A vision that included two of our passions. The first, making sure software content could be trusted in way that is immutable, tamper-proof and cryptographically verifiable. The second, our passion for open source and its developers. We wanted to ensure that any developer, anywhere, …

FOSDEM ’22 Recap: How immudb protects safety critical data (with math and cryptography)

FOSDEM ’22 was held online as a virtual event this year. Our very own immudb core developer Bartłomiej Święcki proudly presented his talk “Don’t trust us, trust the math behind immudb, how immudb protects safety critical data with math and cryptography” as part of the Open Source and Safety Dev Room. Watch the video and …

OpenSSF’s Alpha-Omega Project – Good, but not enough.

On February 1, the Linux Foundation’s OpenSSF announced the launch of its Alpha-Omega project, an initiative aimed at securing what are considered the most “core ecosystem” Open Source projects as well as another 10,000 widely-deployed open source projects. Microsoft and Google have kicked in a collective $5 million to help fund this effort. There are …

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.
