Haraka Hash: A Look at AES-based PoW for Blockchains

Haraka Hash is really interesting to me, it’s not a typical checksum hash function like SHA, or Blake, nor it is a KDF like Argon2 or scrypt. Instead, Haraka is designed as an AES-based permutation , optimized for short inputs and extremely high throughput on modern CPUs with AES-NI instructions. But why? Why would anyone use this? Well, for crypto… Why Use Haraka in Crypto? Haraka’s core idea is…
