Few days back, we created a very simple blockchain on my youtube channel. It demonstrated what a blockchain is really well, but blockchains need some consensus mechanism.
In this example, I have shown a very simple POW consensus mechanism.
Uses GO for the same.
To run -
go run main.go
Open http://localhost:8080 in a browser and you will see one block.
To add blocks, you send a POST request to localhost:8080 using CURL.
Send a BPM like {"BPM":75} in the body of this post request.
curl -X POST -H "Content-Type: application/json" -d '{"name": "75"}'
Your terminal will start performing the work.
Then hit the same terminal from a browser and you will an added block. Voila!
