Episode notes

The secure element is a circuit with low capacity processing. With some crypto accelerator, there are piece of hardware that can accelerate the cryptographic operation. But when I refer to Ledger operating system, like this part is software, it's firmware and this part is implemented inside the secure element. It's possible for the keys to not leave the secure element even when you are doing a signature.

Ledger has been the center of attention since the announcement of their new “Recover” feature which has brought into question how secure our Ledger devices actually are.

Charles joins us to walk through how exactly this recover feature functions, breaking down how a Ledger actually functions, and possible paths moving forward.
