Logchain

Logging secured by blockchain 📜⛓️

Logs get chained

The current log line contains the signature of the previous line with your secret.

• detect lines deleted / lost
• detect logs tampering

Philosophy

The package is intended to be a lightweight util for generating incorruptible logs.

For this pupose we rely as much as possible on standard packages: few dependencies, high quality.

The formatters are easy extensible by simply deriving from Basic.

Usage

Install

npm install node-logchain

Choose your log type

Init once in main

Use everywhere with standard logging

Check your logs integrity afterwards
