During my time at Ledger I identified a few blind spots. Onboarding with true self custody is still too complex, and we've as an industry designed great cryptographic schemes that aren't used as much as they deserved outside of it. So I'll be starting a new team to work on that.

However I missed the efficiency of small dedicated teams. Ledger started with Olivier Tomaz (hardware & low level embedded), Cédric Mesnil (embedded cryptography) and myself (jack of all trades / fan of Buffers) - the architecture and tech vision didn't change.

Thanks to Clave for highlighting the security differences between regular FIDO credentials and Passkeys. I'll take a slightly more tech optimistic bet on this - the current situation is temporary, once the enclaves firmwares are updated Passkeys will also be hardware bound
1/ Passkeys, Secure Enclave, Webauthn... These concepts are often used incorrectly and can be confusing. So, what exactly are they, and what are the key differences between them?
Let's delve into these concepts to gain a better understanding 🧵

I've read several misconceptions about Common Criteria certifications. Typically:
- "Components producers pay for certification"
- "Certifications test only against a known set of predefined scenarios"
- "Certifications are not a replacement for independant review"

Thanks for being at the frontline of new ZK applications and making cryptography cool with great UX, swag and events. Take some well deserved rest and keep writing this story 🫡
Today, Sismo returned funds to its investors.
We shipped fast, solved hard problems and built a great community. Yet, our pace was unsustainable, we sprinted a marathon.
I'm proud of the battle we fought and the way we did it, with full engagement and passion.

step 1 go to

Big fuss ongoing about
