Following is a promise that i use for getting transaction receipt:

function getTransactionReceiptMined(web3Instance, txHash, interval) {
    const self = this;
    const transactionReceiptAsync = function(resolve, reject) {
        web3Instance.eth.getTransactionReceipt(txHash, (error, receipt) => {
            if (error) {
            } else if (receipt == null) {
                    () => transactionReceiptAsync(resolve, reject),
                    interval ? interval : 500);
            } else {

   return new Promise(transactionReceiptAsync);

function sendRawTransaction() {
  let sendRawTxn = async function(resolve, reject){
//web3_inst is web3 object
        web3_inst.eth.sendRawTransaction("0x" + txSerialized.toString('hex'), function(err, result){
            getTransactionReceiptMined(web3_inst, result)


The above code works when i deploy in (local)ganache and (online testnet)ropsten. But when i deploy in geth, i get following output in (powershell) console:

O [03-28|12:05:27.873] Submitted contract creation

Normally the promise calls itself few times until it receives receipt object, but in case of geth, even after receiving the above output which i assume to be contract deployed successfully, the promise is stuck in infinite loop as receipt is always null. How should i solve this?

PS: I am using solc to compile and deploying using nodejs i.e., no truffle. node version: v10.14.2 web3 version: 0.20.7

I think, that the transaction is not getting mined even after waiting for an hour. Also, please explain why difficulty of pending block (131072) is different than that of network (36, which i had set in genesis).



** Until now, I have been doing geth ... --mine, but when I do geth ... console then miner.start() then it starts creating blocks:

INFO [03-29|14:13:23.907] Successfully sealed new block            number=3172 sealhash=74b181…41550f hash=dbba06…c3dba8 elapsed=4.693s

INFO [03-29|14:13:24.103] Commit new mining work 

Is there any difference between using command line mine vs miner.start() ?

  • when i deploy in (local)ganache and (online testnet)ropsten. But when i deploy in geth - this statement doesn't make much sense, because those 3 entities are not under the same category. Ganache and Geth are node types, while "local" and Ropsten is a network types. In order to describe a deployment, you need to specify both, i.e., what node type you're using and to what network type you're deploying. So while local ganache provides a good deployment-description, (online testnet)ropsten doesn't, and neither does geth. Mar 28, 2019 at 6:53
  • I meant in sense of install location, i.e., geth(one node) and ganache on pc, whereas ropsten testnet (endpoint) from infura.

  • Just say which setup works and which doesn't. At present, I see 3 node types and 2 network types, so there are 6 possible setups, and I'm pretty sure that you've tried only some of them, so please explain which combinations you've tried and what result you get for each combination. Mar 28, 2019 at 7:07
  • I tried on: 1. geth local 2. ganache local 3. ropsten testnet (endpoint from infura)
