Polygon zkEVM API method that returns the current batch number of the chain. The Polygon zkEVM uses batch verification to improve scalability and reduce gas fees. This means that multiple transactions are grouped together and verified as a single batch using zero-knowledge proofs. The zkevm_batchNumber method returns the current batch number of the zkEVM, which is used to identify the latest batch of transactions being verified.
