## Hash throughput

## Memory store (ETS, BLAKE3 CID)

| op | size | throughput |
| --- | ---: | ---: |
| put | 1 MiB | 1273.2 MiB/s |
| get + verify | 1 MiB | 1421.0 MiB/s |

## Digest agreement

Zig BLAKE3 == Rust BLAKE3 (and XXH3): **true**.

BLAKE3 is the content id. XXH3 is checksum-only. OTP SHA-256 is the S3 SigV4 floor, not a CID.
