# Test format: Ethereum-customized BLS fast aggregate verify Verify the signature against the given pubkeys and one message. ## Test case format The test data is declared in a `data.yaml` file: ```yaml input: pubkeys: List[BLS Pubkey] -- list of input BLS pubkeys message: bytes32 -- the message signature: BLS Signature -- the signature to verify against pubkeys and message output: bool -- true (VALID) or false (INVALID) ``` - `BLS Pubkey` here is encoded as a string: hexadecimal encoding of 48 bytes (96 nibbles), prefixed with `0x`. - `BLS Signature` here is encoded as a string: hexadecimal encoding of 96 bytes (192 nibbles), prefixed with `0x`. All byte(s) fields are encoded as strings, hexadecimal encoding, prefixed with `0x`. ## Condition The `eth_fast_aggregate_verify` handler should verify the signature with pubkeys and message in the `input`, and the result should match the expected `output`.
