I have setup a private blockchain in AWS micro instance using go-ethereum. In that when I start the mining process it was taking nearly 2-3 hours to mine a new block.Whereas on my local machine it was taking 30 mins initially to start after that it took 1 sec to mine a new block. In Genesis block, I had assign difficulty as 0x400.

{
    "config": {
        "chainId": 15,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
    "nonce": "0x0000000000000042",
    "difficulty": "0x400",
    "gasLimit": "2100000",
    "alloc": {
        "0xc490758cadb047809fa59df82a2057e6407784ab": { "balance": "100000000000000000000000000" },
        "0xa4f6f95b6cb36025dd09c9f5fe068e401951e963": { "balance": "10000000000000000000" }
    }
}
  • I think you are having problems with the dag generation, don't you? – Florian Castelain Feb 15 '18 at 9:43
  • For private blockchain you can use PoA then the block time can reduce to seconds. – Ha ĐANG Sep 6 '18 at 9:30

Please use t2 medium instances of AWS. Preferrably 2 instances. connect the 2 nodes by addPeer, Start mining in one instance. connect nethereum on the other and transactions would take 4-5 seconds.

    Can you explain why? – Grzegorz Feb 15 '18 at 10:04
