Hey! I'm David, the author of the Real-World Cryptography book. I'm a crypto engineer at O(1) Labs on the Mina cryptocurrency, previously I was the security lead for Diem (formerly Libra) at Novi (Facebook), and a security consultant for the Cryptography Services of NCC Group. This is my blog about cryptography and security and other related topics that I find interesting.

And now some history about how the word Entropy was "coined" by Shannon. Taken from Tobin - Entropy, Information, Landauer’s limit and Moore’s law


Well done! You've reached the end of my post. Now you can leave a comment or read something else.
