Test format: Blob to KZG commitment

Compute the KZG commitment for a given blob.

Test case format

The test data is declared in a data.yaml file:

input:
  blob: Blob -- the data blob
output: KZGCommitment -- The KZG commitment
  • blob here is encoded as a string: hexadecimal encoding of 4096 * 32 = 131072 bytes, prefixed with 0x.

All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with 0x.

Condition

The blob_to_kzg_commitment handler should compute the KZG commitment for blob, and the result should match the expected output. If the blob is invalid (e.g. incorrect length or one of the 32-byte blocks does not represent a BLS field element) it should error, i.e. the output should be null.
