Post quantum security of the BLAKE family

Is there any proof that BLAKE (including 2 and 3) is post-quantum secure? We know that as Merkle–Damgård (with proper padding) preserves collapse sha2 is post-quantum secure. I know that the sponge-...

Can Blake2 be a replacement for double SHA-256?

My previous question was closed because it was too open-ended, so let me simplify the question: Is it a good choice to drop double SHA-256 and use straight Blake2 in a Bitcoin-like blockchain (more ...

Using platform-level RNGs for key derivation with hash functions like BLAKE3?

So I've read stack overflow questions like this one. What I'm wondering is a bit more specific though: I'm really liking what I'm seeing with BLAKE3. (I suspect that this hash function is relatively ...
