How it came to be

Preface

Some time ago I wrote PURR (Protocol for Universal Request-Response Communication) to teach my friend how to implement custom TCP protocols in Go. I took it as the foundation, added proof-of-work checking to the request-response cycle and voila!

I used go-pow as my PoW algorithm.

Main

Once that was done, all that's left to do is fill up the cmd folder with the main files (client and server) that satisfy functional requirements. I called the server - teach; and the client is called - learn.

For the server, I found some quotes here and copied them over as strings.

Dockerization

Dockerfiles are stored in the .docker folder. The resulting images are built FROM scratch and contain just the Go binary, which makes them nice and lightweight at around 3MB each.

Notes

I wouldn't call this a production-ready technology. The server doesn't implement any kind of graceful connection handling (e.g. telling the client what's wrong in case of a transaction error).

This is simply a PoC server that uses PoW to PIMAGSE (prove I'm a good software engineer). Yeah, it's a pun. Hope you appreciate a little bit of humour.
