I have setup my one ethereum node successfully and I want to mine contract which was not mined yet on maine ethereum network, can it’s possible ? if possible then how much hash power need to achieve ? please help me.
If you have a transaction waiting in the pool that you want included in a block, then you could resend the transaction with the same nonce and a higher gas price. Gas prices are still in the 20-30Gwei range: https://www.ethgasstation.info/
I don’t know much about mining unfortunately.
There are some online calculators that you might be able to use to see how long it might take to mine a block given the hash rate of your hardware. Though I haven’t used any so can’t vouch for how good they are.
Etherscan shows the hashrate:
As for including your own transaction into a block, I assume this is possible, though I don’t know how to do this.
Sorry I can’t be more helpful on this. There may be other community members who could advise.
Thanks @abcoathup for your time.
