I wanted to transfer 5 etheres from my coinbase address to my another account. My coinbase balance is:

    > eth.getBalance(eth.coinbase)

So I transferred it and sendTransaction gave txhash also

     > personal.unlockAccount(eth.coinbase, "jevel")
 > eth.sendTransaction({from:eth.coinbase, 
to:"0xe773d39957869a5edf76285fadb78e49875f273e", value:web3.toWei(5, 
"ether"), gas:21000})
INFO [09-24|10:38:50.553] Submitted transaction                    

but when I checked it, it was showing null:


After that I mined my transaction :

> miner.stop()

Then I checked the number of blocks mined:

    > eth.blockNumber

It is showing 0.

My private network have zero peers. Is that the problem???

  • It seems to be a bug, unless you are doing something wrong. Have a read here Alternatively, the transaction never gets mined. Please try to increase the gas limit by noticeable amount

  • @cryptoS. You didn't mine a block yet. Make sure the difficulty on your private testnet is not too high.

It took time for mining to start, initially, it was generating DAG but eventually successful to transfer ether.
