S4 E7: Peter Todd on Hardware Wallets, Security & Proofmarshall

Intellectually speaking, Peter Todd has been a bitcoiner before Satoshi Nakamoto even emerged on the cypherpunk mailing list. As a cryptography and computer science enthusiast, he would try to solve the double-spending problem with Hal Finney and Adam Back when he was just fifteen. His work and credentials definitely qualify him as a cypherpunk, but it’s his relentless critical spirit and adversarial thinking that make him stand apart.

As a true iconoclast, Peter Todd is not afraid to ask the questions that defy canons and would definitely call out the emperor for his nakedness in spite of authoritarian pressures to recognize the existence of clothes.

For these reasons, Todd is the perfect critic of hardware wallets, and the right kind of person to explain how ideal security setups should function. Though he avoids giving specific advice, Peter Todd does promote the development of a critical thinking mechanism which adapts to threats and preemptively phases out possibly disastrous scenarios.

The inclusion of Todd in season 4 of the Bitcoin Takeover Podcast marks a significant shift in tone, as for the first time during the series the guest has absolutely no involvement in the hardware wallet or cold storage business. By having no skin in the game, he can be brutally honest.

Throughout this two-hour interview, the cypherpunk is candid and merciless when it comes to criticizing the lack of transparency that certain manufacturers show.

And when he doesn’t explain why hardware wallets are terrible and how cold storage is best maintained, Peter Todd also talks about his latest project: Proofmarshall. If you’re able to help build the project (also described during the podcast at 1:17:00) or would like to audit it, feel free to contribute on the public GitHub repository.
