Data RelayX

We Team Aakash, built the prototype of the product Data RelayX to provide Resilient Decentralized Data communications & Data Storage in swarm troops. Aiming to enhance the security & resiliency of most sensitive & confidential UAV data. We aim to solve the most unique challenges faced by swarm troops in handling the most confidential Unmanned Aerial Vehicle (UAV) data.

Technology Stack

Frontend Stack

• HTML
• CSS
• JavaScript
• React ( Later )

Backend Stack

• Polkadot's Substrate node template
• My SQL Database
• IPFS
• Data serialization algorithms
• Selenium

Cloud Services

• AWS Lambda Serverless application models
• Amazon Keyspaces apache Cassandra

Prerequisites:

OS: Ubuntu (>ver 20) in WSL2.

• Applications: (All In WSL2)

1. google-chrome and it's web driver
2. python3 and Selenium
3. git
4. rustc and cargo ( for rust and cargo configuration follow : 'https://docs.substrate.io/install/windows/' )

How to run

1. First Install WSL then install rustc and cargo in wsl (follow : 'https://docs.substrate.io/install/linux/' ) First Open command prompt and type:

wsl

Then Clone the repo

git clone https://github.com/IBC-Media/Grant-Akash.git

And run the chain using :

cd Grant-Akash

cargo update

cargo build --release

./target/release/node-template --dev

Interact with the Blockchain :

https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A9944

2. In Windows Install XAMPP server & paste the blob1 in the below path :

C:\xampp\htdocs

3. Run XAMPP server & start Apache & My SQL services
4. Create a Database named test_blob1 & the table named table1 in phpMyAdmin
5. Run the application to encrypt, store & push the Drone generated images to substrate's DLT

localhost/blob1/index.php

6. An automated selenium script will push the Time stamp & CID into the substrate's DLT by accessing polkadotjs extrinsics
7. You can also run the selenium script manually to push & retrieve the data

cd drx
python test.py

This Contains a Custom Pallet named telemetryPallet that has 2 important functions:
Data Pushing: Store A Key-Value Pair onto Blockchain.
Data Retrieval: Retrieve value based on given key.
