# DDoS as an Altcoin

As part of my CS 401R (Blockchain) class at BYU, I researched an interesting idea called DDoSCoin. I found the idea [here](https://www.usenix.org/conference/woot16/workshop-program/presentation/wustrow).

## Summary
DDoSCoin is an instance of "useful proof of work". Essentially, someone can set a bounty on a TLS-enabled server, and workers must prove they have made the specified number of connections to the target server by producing a digital signature prefixed with n zeros.
