# Light Client A contract that verifies the proof, and developers can define it on their own. In the initial stage, a mock-up verification using Patricia Merkle Tree (MPT) is created for account proof and storage proof. Verification methods such as ZKP will be implemented in the future. The Light Client Contract defines the `requestQuery` and `verify` functions as interfaces. Also, since verification requires the acquisition of block headers (state root), the method of acquisition can be customized within this contraption at this time ([Konoha](/docs/protocol/konoha.md)). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://futaba.gitbook.io/docs/protocol/light-client.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
