Polygon zkEVM API method that returns the latest consolidated block number.

The Polygon zkEVM chain 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. Once a batch is verified, it is connected to the blockchain, and the block number of the most recent block in that batch becomes the “consolidated block number.”
