Proof of work Spec #130

Closed roeslpa closed 8 years ago

roeslpa commented 8 years ago

Wrote a more specific description of the proof of work. Resolves #68

cburkert commented 8 years ago

@roeslpa Your suggestion looks plausible to me. However, I know too little about proof-of-work protocols to do a in-depth analysis. For now, this should do, but we should keep this in mind for later auditing. Furthermore, I'd would be useful to read what inspired your suggestion (existing protocols).

@cburkert : was that an "ack"?

roeslpa commented 8 years ago

@cburkert I added my inspiration and modified the protocol to prevent precomputation. Would you ack for now and we keep it in mind for an audit?

thechauffeur commented 8 years ago

I have several question about this spec until I can ack it. We should discuss this in real-time and post the outcome here.

In any case we need an issue (enhancement, future work) about independently auditing the proof-of-work spec.

thechauffeur commented 8 years ago

My questions are answered and this spec looks sane to increase the amount of work someone must do to (D)DoS the (drop) system.

We could force this protocol only on suspicious connections (e.g. on connections using IPs with more than r requests per time unit).
