EVM implementation of the
headBlockNumbertracking mode. In this new mode, new block hashes event are still used as a shoulder tap event to trigger the chain head refresh usingeth_blockNumbercall, which will fetch the latest chain head. However, the logic no longer makes the heavy calls to fetch the detailed information of each block; therefore, it hugely reduces the amount of data fetched from the configured JSON-RPC endpoint.The following eth method is no longer required when
