Dear community. immudb has just been released as v0.6.2

Release v0.6.2 fixes some important bugs and has many improvements – we recommend updating to it

Bug Fixes

  • require auth for admin commands even if auth is disabled on server, do not allow admin user to be deactivated
  • base64 decoding of passwords: now it requires the "enc:" prefix as base64 can not be differentiated from plain-text at runtime (e.g. "immu" is a valid base64 encode string)
  • only require admin password to be changed if it is "immu"
  • fix ldflags on dist binaries and add static compilation infos
  • cmd/immuclient/audit: fix base64 encoded password not working with immuclient audit-mode
  • immuadmin: repair password change flow right after first admin login
  • pkg/auth: make ListUsers require admin permissions
  • pkg/ring: fixes cache corruption due to a ring buffer elements overwrite on same internal index
  • pkg/store: remove useless ringbuffer array
  • pkg/store: fix uniform cache layers size allocation with small values


  • add bug and feature request report github template
  • fix golint errors
  • githubactions add windows and build step
  • remove plain-test admin password from log outputs
  • add message (cli help and swagger description) about base64-encoded inputs and outputs of get and set commands
  • FreeBSD section in the readme
  • fix changelog auto generation repo and releasing template
  • pkg/server: reduce corruption-checker resource usage


  • expose through REST the following user-related actions: create, get, list, change password, set permission and deactivate
  • immuclient freebsd daemon installation
  • freebsd service install
  • read immudb default admin password from flag, config or env var
  • use immu as default admin password instead of randomly generated one
  • immudb: accept base64 string for admin password in flag/config/env var

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.
