Immutable

Immutable

Any kind of key-value. Clients can choose how to structure data.

No data mutation APIs are provided.

Data is never overwritten, so multiple versions of the same key co-exist and are verifiable.

Auditable

Auditable

Tamper-evident history system.

Clients and auditors want cryptographic proof of data inclusion and historical consistency in real time.

If tampered, clients and auditors will notice that and take actions.

Secure

Secure

Data ownership is verifiable by clients and auditors.

Sign your data using Public-Key Cryptography.

Keys additions and revocations is immutably stored into the database

Runs on

Easy setup

Build Docker images based on the Dockerfiles in the GitHub repository for the most common architectures or use the prebuild ones on Dockerhub for Linux.
docker run -it -d -p 3322:3322 -p 9497:9497 --name immudb codenotary/immudb:latest

Unmatched performance

immudb has been designed with read and write performance in mind while being tamper-proof. The benchmarks we've done show great results.

Why immudb?

immudb is a ledger database that has been developed with performance, scalability and versatility in mind. The user feedback has shown that they love the very high throughput and being able to store hashes as well as data. They see it as a great alternative to using a blockchain or ledger service.

  • Easy setup
  • Fast and reliable immutable database
  • Secure REST API gateway
  • Powerful, easy to use admin
  • Open source

Very high throughput, immutable database with cryptographic verification

immudb is an indispensable asset when it comes to tamper-proof data:

  • Store every update to sensitive database fields (credit card or bank account data) of an existing application database
  • Store CI/CD recipes to build and deployment pipelines
  • Store public certificates
  • Store tamper-proof log streams (i. e. audit logs)
immudb
// Store any key, value auditproof and tamperproof
key2, value2 := []byte("myClient"), []byte("Visa 6679499384784022 11/23")
verifiedIndex, err := client.SafeSet(ctx, key2, value2)
if err != nil {
   exit(err)
}
fmt.Println("   SafeSet - add and verify entry:")
printItem(key2, value2, verifiedIndex)
immudb
# install immudb service
./immuadmin service immudb install

# check current immudb service status
./immuadmin service immudb status

# install immugw service
./immuadmin service immugw install

# check immugw service
./immuadmin service immugw status
immudb - intuitive setup

Intuitive setup

immudb is built with simplicity in mind:

  • Use the prebuilt binaries or Docker container images for a fast start
  • Install, manage and run immudb and immugw as services (use 'immuadmin service')
  • Simple make command integration if you want to build the applications yourself
  • RESTful interfaces and easy to use clients
  • Combine with any existing application
Immudb - Made for the real world

Consistency check built-in

immudb architecture has built-in verification and audit functionality:

  • immudb server is continuously checking disk/memory consistency
  • immugw is continuously checking the data consistency and integrity
  • immuclient has built-in data consistency and integrity checks
  • API's provide data ownership proof, verification and integrity functions
immudb
// built-in verification for every entry
verifiedItem, err := client.SafeGet(ctx, key2)
if err != nil {
    exit(err)
}
fmt.Println("   SafeGet - fetch and verify entry:")
printItem(nil, nil, verifiedItem)
