Trezor CTO outlines wallet trade-offs for Bitcoin post-quantum signatures
Trezor CTO Tomáš Sušánka says SHRINCS, the leading post-quantum signature proposal for Bitcoin, is difficult for hardware wallet makers because its stateful option needs precise state tracking to prevent fund theft. Trezor is considering making the larger, slower stateless signatures the default and hiding the stateful option in advanced settings. He also said hardware devices need post-quantum firmware authentication, which the Trezor Safe 7 already supports.
Trezor cuts reseller network by 80% after more spy implants found
Trezor has cut its reseller network by 80% after finding more spy implants in wallets sold by Malaysian vendor CryptoBilis, with only 20% of vendors meeting its new sourcing and access rules. It says an update released on November 11 changes the order of display commands so the implants no longer capture the seed phrase, but it still advises CryptoBilis customers to move funds to a new wallet because backups captured earlier remain at risk. Three Trezor Safe 5 units have been found implanted, all bought between August 20 and September 23, and Trezor says no funds have been stolen.
