# Test format: BLS hash-compressed
A BLS compressed-hash to G2.
## Test case format
```yaml
input:
message: bytes32
domain: bytes8 -- the BLS domain
output: List[bytes48] -- length of two
```
All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with `0x`.
## Condition
The `msg_hash_g2_compressed` handler should hash the `message`, with the given `domain`, to G2 with compression, and the result should match the expected `output`.
