just got my cypherock.com in mail!

i'm an avid ledger fan (been gifting them on xmas to basically everyone i could reach my hands to)

however, the premise of having physical multi-party cards instead of a seed on a piece of paper is intriguing

maybe this xmas i'll be sending cypherock https://i.imgur.com/3uysQLs.jpg

@cassie where do you stand on hardware wallets?

I trust in redundancy and math over hardware which is never fully auditable (without an electron microscope) — hardware implementations may be better than software, but MPC of hardware or software is better than either alone

It’s not — they just Shamir split 2-of-5 with four onto tap cards and one on the wallet, then combines in memory on demand for use. The secret split might be MPC, but when the signing is performed, it’s plain old 1PC

if i understood correctly this is a hardware version of mpc
