# Single leaf merkle proof tests
|
||
|
|
||
|
This series of tests provides reference test vectors for validating correct
|
||
|
generation and verification of merkle proofs based on static data.
|
||
|
|
||
|
## Test case format
|
||
|
|
||
|
### `state.ssz_snappy`
|
||
|
|
||
|
An SSZ-snappy encoded `BeaconState` object from which other data is generated.
|
||
|
|
||
|
### `proof.yaml`
|
||
|
|
||
|
A proof of the leaf value (a merkle root) at generalized-index `leaf_index` in the given `state`.
|
||
|
|
||
|
```yaml
|
||
|
leaf: Bytes32 # string, hex encoded, with 0x prefix
|
||
|
leaf_index: int # integer, decimal
|
||
|
branch: list of Bytes32 # list, each element is a string, hex encoded, with 0x prefix
|
||
|
```
|
||
|
|
||
|
## Condition
|
||
|
|
||
|
A test-runner can implement the following assertions:
|
||
|
- Check that `is_valid_merkle_branch` confirms `leaf` at `leaf_index` to verify
|
||
|
against `has_tree_root(state)` and `proof`.
|
||
|
- If the implementation supports generating merkle proofs, check that the
|
||
|
self-generated proof matches the `proof` provided with the test.
