Exploring Bitcoin's Proof of Work in TypeScript

Bitcoin Reddit

More / Bitcoin Reddit 68 Views

Hi everyone,

I’ve put together a video that walks through a simplified TypeScript implementation of Bitcoin’s Proof of Work consensus mechanism. In the video, I break down block header construction, double SHA256 hash calculations, and the mining process itself. It’s a humble effort to demystify the inner workings of Bitcoin mining and show how these core concepts secure the network.

If you’re curious about the nuts and bolts of Bitcoin’s security model, I hope you enjoy the video and find the GitHub source code useful!
