# Test format: Compute KZG proof
|
||
|
|
|
||
|
|
Compute the KZG proof for a given `blob` and an evaluation point `z`.
|
||
|
|
|
||
|
|
## Test case format
|
||
|
|
|
||
|
|
The test data is declared in a `data.yaml` file:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
input:
|
||
|
|
blob: Blob -- the data blob representing a polynomial
|
||
|
|
z: Bytes32 -- bytes encoding the BLS field element at which the polynomial should be evaluated
|
||
|
|
output: KZGProof -- The KZG proof
|
||
|
|
```
|
||
|
|
|
||
|
|
- `blob` here is encoded as a string: hexadecimal encoding of `4096 * 32 = 131072` bytes, prefixed with `0x`.
|
||
|
|
- `z` here is encoded as a string: hexadecimal encoding of `32` bytes representing a little endian encoded field element, prefixed with `0x`.
|
||
|
|
|
||
|
|
All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with `0x`.
|
||
|
|
|
||
|
|
## Condition
|
||
|
|
|
||
|
|
The `compute_kzg_proof` handler should compute the KZG proof for evaluating the polynomial represented by `blob` at `z`, 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) or `z` is not a valid BLS field element, it should error, i.e. the output should be `null`.
