By implementing ECDSA natively in assembler, he was able to speed up signing by 21x. Let's hope it is resistant to side-channel attacks[0] ;) [0] https://news

- lallysingh 11y agoI don't think side channels are an attack vector for them. These are running on machines that they own, and where they control all the software on them. I wonder if removing side-channel countermeasures was part of the optimization?
- mindslight 11y agoSome side channels travel over networks. Timing, for instance.
