# Verify

Function to verify proof

This function uses Merkle Patricia Trie (MPT) to verify the proof.

```solidity
function verify(
    bytes memory message
) public returns (bool, bytes[] memory);
```

<table><thead><tr><th width="133.5">Field</th><th>Description</th></tr></thead><tbody><tr><td><code>message</code></td><td>Data encoded with proof information (You can get an array of <code>Proof</code> when you decode)</td></tr></tbody></table>

What the `verify` function does:

* Verify account proof using MPT to obtain the target storage hash
* Verify the storage proof using MPT to obtain the value of the target storage slot

This validation is used in the initial phase and other validation methods may be developed as modules in the future, such as the use of zkp.
