Few days back, we implemented a simple blockchain on my youtube channel.
But blockchains aren't in silos, they need consensus mechanisms for adding new blocks.
I've added a proof of work example in my github, this one is a proof of stake example.
For proof of stake, you need to give different amount of tokens to different peers.
This means, you will create multiple peers by -
- Starting the server for the blockchain by
go run main.go - Opening multiple terminal instances and typing
nc localhost 9000 - Each of these terminals will be a new peer and you can see the proof of stake happening in action in the terminal
- There will be one clear winner and the hash of that peer will be mentioned in the terminal
