View the "pending" Block

This section describes how to view the 'pending' block.

After running the 'geth' miner for more than a hour, I still don't see any new blocks generated.

Let's check to see if there any "pending" blocks waiting to be "mined":

> eth.getBlock("pending")
{
  difficulty: 17171480576,
  extraData: "0xd983010801846765746887676f312e392e328777696e646f7773",

  hash: null,
  logsBloom: "0x00000000000000000000000000000000000000000000000000000...",
  miner: null,
  mixHash: 
     "0x0000000000000000000000000000000000000000000000000000000000000000",
  nonce: null,
  number: 1,
  parentHash: 
     "0xd4e56740f876aef8c010b86a40d5f56745a118d0906a34e69aec8c0db1cb8fa3",

  timestamp: 1520195159,
  totalDifficulty: 0,
  transactions: [],
  transactionsRoot: 
     "0x56e81f171bcc55a6ff8345e692c0f86e5b48e01b996cadc001622fb5e363b421",
  uncles: []
}

Good. We have an empty block (no transactions) in the queue pending to be "mined".

May be the issue is that my "miner" is too slow to find the magic "nonce". See next tutorial on how to speed up the miner performance.
