New: immudb Coding Challenge - Winter 2020 Edition #immuchallenge

immudb is not a blockchain, immudb is the lightweight, high-speed immutable database with built-in cryptographic proof and verification. With immudb you can track changes in sensitive data in your transactional databases and then record those changes permanently in a tamperproof immudb database. This allows you to keep an indelible history of sensitive data, for example debit/credit card transactions.

Traditional DB transactions and logs are hard to scale and are mutable. So there is no way to know for sure if your data has been compromised.

As such, immudb provides unparalleled insights retroactively of changes to your sensitive data, even if your perimeter has been compromised. immudb guarantees immutability by using cryptographic data structures internally.

immudb gives you the same cryptographic verification of the integrity of data written with SHA-256 like a classic blockchain without the cost and complexity associated with blockchains today.

immudb has 4 main benefits:

immudb is immutable. You can add records, but never change or delete records.
Data stored in immudb is cryptographically coherent and verifiable, like blockchains, just without all the complexity and at high speed.
Anyone can get started with immudb in minutes. Whether you're using node.js, Java, Python, Go, .Net, or any other language. It's very easy to use and you can have your immutable database running in just a few minutes.
Finally, immudb is Open Source. You can run it on premise, or in the cloud. It's completely free. immudb is governed by the Apache 2.0 License.

immudb can be ran on Linux, FreeBSD, Windows, and MacOS, along with other systems derived from them, such as Kubernetes and Docker.

Quickstart

Getting immudb up and running is quite simple. Choose any of following options:

Running immudb in Docker
Download immudb release binary
Build immudb by yourself
Running as a service

Running immudb in Docker

Pull immudb Docker Image from Docker Hub:

docker pull codenotary/immudb:latest

Run immudb in a container:

docker run -it -d -p 3322:3322 -p 9497:9497 --name immudb codenotary/immudb:latest

immudb should be up and running, you can check the container logs:

docker logs immudb

Download immudb release binary

Download latest release binaries from here. Then just run immudb as follows:

# run immudb in the foreground
./immudb

# run immudb in the background
./immudb -d

To stop immudb in that case you need to find the process ps -ax | grep immudb and then kill -15 <pid>. Windows PowerShell would be Get-Process immudb* | Stop-Process.

Using immudb

Integrate immudb into your application using official SDKs already available for the following programming languages:

Java immudb4j
Golang immudb-go
.net immudb4dotnet
Python immudb-py
Node.js immudb-node

We've developed a "language-agnostic SDK" which exposes a REST API for easy consumption by any application. immugw may be convenient tool when SDKs are not available for the programming language you're using, for experimentation, or just because you prefer your app only uses REST endpoints.

For a super quick start, please follow step by step guides for each SDK or pick a basic running sample from immudb-client-examples. Otherwise, you can use the immudb CLI tools described below.

CLI tools

immuclient is the CLI client for immudb. You can read, write data into immudb from the commandline using direct or interactive mode.
immuadmin is the admin CLI for immudb. You can manage immudb and get statistics as well as runtime information.

The latest release binaries can be found here

Real world examples

We already learned about the following use cases from users:

use immudb to immutably store every update to sensitive database fields (credit card or bank account data) of an existing application database
store CI/CD recipes in immudb to protect build and deployment pipelines
store public certificates in immudb
use immudb as an additional hash storage for digital objects checksums
store log streams (i. e. audit logs) tamperproof

Companies using immudb

Opvizor - immutable log (syslog) solution for VMware vSphere

Multiple databases

It is possible to create and use many databases. There is no hardcoded limit on the number of database immudb can handle, but keep in mind that for every database created, 4 more file descriptor will be used. Also, the database name must be shorter that 128 bytes, in order to comply with filesystem limitations. This is because every database is stored in a directory which has the same name of the database. For the same reason, special characters (such as /) in the database name must be avoided.

The default number of open file per process on modern linux systems is usually 1024. Thats mean that without increasing that number, immudb is limited to about 250 databases. It's easy to increase that limit.

If you are using systemd services, you only need to set LimitNOFILE=65536 in the service file, and restart the service.

With systemV init, you have to put ulimit -n 65536 in your init file, before launching immudb.

It is also possible to modify /etc/security/limits.conf, which sets the system defaults.

If you are using a dedicated immudb user, just add:

# /etc/security/limits.conf
immudb    hard    nofile      65536
immudb    soft    nofile      65536
