@macfarla I’ve been working on understanding the implementation of the eth_getBlockByNumber JSON-RPC method within the project. Still, I’ve been having trouble locating the specific code where this method is implemented and handled.

Could you kindly point me to the implementation of the eth_getBlockByNumber method, or let me know if there are any resources or documentation that would help me understand how these methods are structured and processed?
