Cryptographic hash types for SUM Chain.

We use Blake3 for all hashing operations. Blake3 is:

  • Extremely fast (faster than MD5 while being cryptographically secure)
  • Designed by world-class cryptographers (same team as Blake2)
  • The reference implementation is written in Rust
  • Parallelizable and SIMD-optimized
