I have created two personal account on private blockchain with geth. This is the balance of one account

web3.fromWei(eth.getBalance(eth.accounts[0]), "ether");


And this is of the second one

 web3.fromWei(eth.getBalance(eth.accounts[1]), "ether");

I unlocked first account

Unlock account 0x942282c0793fb08dea160c74ac45b5d4f2d03192

When i try to send transaction or transfer from one to another, it executes successfully

eth.sendTransaction({from: '0x942282c0793Fb08dEA160C74AC45B5D4F2D03192',to: '0x7258CB67ccBCF4AC755e5D7F0891e9415B683129',value: '1000000000'})

But changes are not reflected when i again check balance accounts.

This is the genesis.json that i have used for blockchain setup.

  • AFAIK, function eth.getBalance returns a promise, which you can resolve into a BigNumber object (or possibly a string which represent an integer value). So you should first resolve this promise (for example, by adding await before eth.getBalance). – goodvibration Feb 19 '19 at 11:49
  • @goodvibration Thanks for reply. It turns out my private blockchain was taking too long to mine a new block, at least 20 minutes thus it was not reflecting changes immediately, is it due to difficulty ? How much i should i reduce it, if i have private network of one or two nodes. Can you guide?. TIA – Saeedi Feb 19 '19 at 14:02
  • I use "difficulty": "0x20000" and it works fine. – goodvibration Feb 19 '19 at 15:19
