zkSync block number
Latest block number and block details on zkSync Era, or any block by decimal number: hash, timestamp, transaction count, gas used and limit, base fee in gwei and producer. Use for timestamps and confirmation counts; for current fees use zksync_gas. A block that does not exist yet returns 422, uncharged.
