I used in the eth client web3.eth.sendTransaction({from:sender,to:receiver,value:amount)
to try send some ether, typed yes to the question, then got a hash number 0x6ec7a8ea0e4cf1b381abea7a03e84338fe75a1c8f47767a8da18255508066ac5
.
Looking at etherscan it looks like the transaction is non-existent.
Checking my accounts values, they didn't move.
How can I know it failed or succeeded and if it failed, then why?
