Test format: Verify cell KZG proof
Use the cell KZG proof to verify that the KZG commitment for a given cell is correct.
Test case format
The test data is declared in a data.yaml file:
input:
commitment: Bytes48 -- the KZG commitment
cell_index: CellIndex -- the cell index
cell: Cell -- the cell
proof: Bytes48 -- the KZG proof for the cell
output: bool -- true (correct proof) or false (incorrect proof)
Bytes48is a 48-byte hexadecimal string, prefixed with0x.CellIndexis an unsigned 64-bit integer.Cellis a 2048-byte hexadecimal string, prefixed with0x.
All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with 0x.
Condition
The verify_cell_kzg_proof handler should verify that commitment is a correct KZG commitment to cell by using the cell KZG proof proof, and the result should match the expected output. If the commitment or proof is invalid (e.g. not on the curve or not in the G1 subgroup of the BLS curve), cell is invalid (e.g. incorrect length or one of the 32-byte blocks does not represent a BLS field element), or cell_index is invalid (e.g. greater than the number of cells for an extended blob), it should error, i.e. the output should be null.
