Solana NoStd blake3

A more efficient implementation of Blake3 for SVM.

Installation

cargo add solana-nostd-blake3

Features

  • Adds hash_ref which takes in any type that implements <AsRef<[u8]>>
  • No Hash struct. Returns [u8;32] directly.
  • Makes use of MaybeUninit to skip zero allocations
  • Adds hash_into to let you hash directly into a mutable buffer.

Performance

library function CU cost
nostd-blake3 hashv(&[b"test"]) 100
nostd-blake3 hash(b"test") 105
nostd-blake3 hash_ref("test") 105
solana-program hashv(&[b"test"]) 120
solana-program hash(b"test") 123
