The debug_traceBlockByHash method returns execution traces for all transactions in a block, identified by its block hash on the Arbitrum network.
It is useful for:

Debugging full block execution

Analyzing patterns inside a block

Reviewing internal calls, gas usage, and failures

Understanding transaction flows at a low level

This method is primarily used by developers, indexers, and advanced debugging tools.
