LCaaS is a Python-based blockchain tool. It receives data through its API and then use its internal blockchain framework to convert data to blocks and then pushes them to blockchain by establishing hash-binding relationship among blogs.

Furthermore, LCaaS, introduces a solution for the common capacity challenges of the blockchains. In LCaaS, we have introduced a novel solution referred to as “Hierarchical ledger” or also known as “Multi-dimensional blockchains”. For more information, navigate to google scholar page and search for “Logchain as a service” and have your fingers crossed, if you see something along the following lines, you are good to go!

LCaaS includes:

• API for incoming traffic
• Proprietary private blockchain implementation
• Integration with Firebase Realtime Database
• Integration with Ethereum Test Network (Ropsten)
• Configurable functionalities (check config.json for more information)

LCaaS uses a number of projects:

• Firebase - Google Real-time Database
• Ropsten Test Network - Ethereum Test Network (based on PoW)

LCaaS is designed and developed with Python 3.6 and make use of the following Python Libraries:

• pyrebase
• ethereum
• flask
• hashlib
• TimeKepper
• json
• web3
• contract_abi

Dillinger requires Node.js v4+ to run.

Download the source code and make sure you have the above libraries in your python environment, then, proceed with the following command:

Python index.py

Since LCaaS runs its own internal web server, you should be able to open any broswer and put:

http://127.0.0.1:5000/

You should see the following message on your web-broswer indicating that LCaaS is running.
