Oddbean new post about login | logout I've heard @NVK and guests talk about various trade-offs between seed storage schemes, but never about SeedXOR hammering (2-of-3 SeedXOR, using only XOR operation and uses/produces 3 valid BIP39 seeds). Seems like a nice to have feature on my coldcard, but are there any downsides to this scheme? https://cp4space.hatsya.com/2021/09/10/hamming-backups-a-2-of-3-variant-of-seedxor/ https://github.com/AndreasGassmann/seed-xor-hamming
