Hey! I'm David Wong,
a crypto engineer at O(1) Labs. Previously I was the security lead of the Diem (formerly Libra) blockchain at Novi (Facebook). And before that, I was a security consultant at the Cryptography Services (NCC Group). I'm currently writing a book called Real-World Cryptography.
You can find more about what I do on my blog. This webpage serves to document things I've done.
