This is amazing. Peter Todd has some intense software security knowledge. And "much of his research covers Proof of Publication and Embedded Consensus systems, both highly relevant to Counterparty technology." (

Thanks, although I wouldn't call my knowledge "intense" myself. Rather I'd describe it as very different from what other auditors normally look at. Having Sergio do an audit as well was a smart choice - he thinks very differently than I do and finds issues that I miss all the time, and vice versa!
