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!
