My genesis.json file:

{
  "config": {
        "chainId": 10,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
  "alloc"      : {},
  "coinbase"   : "0x0000000000000000000000000000000000000000",
  "difficulty" : "0x20000",
  "extraData"  : "",
  "gasLimit"   : "0x2fefd8",
  "nonce"      : "0x0000000000000042",
  "mixhash"    : "0x0000000000000000000000000000000000000000000000000000000000000000",

  "timestamp"  : "0x00"
}

Initiated geth with the following command:

~ geth --datadir="./prinet-betty/data/" init prinet-betty/genesis.json
~ eth --fast --cache=1024 --rpc --rpcaddr="localhost" --rpccorsdomain="*" --datadir="./prinet-betty/data" --nodiscover --rpcapi="db,eth,net,web3,personal" console

The following code returns the error

const Web3 = require("web3");

let web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));

web3.eth.getAccounts((err, acc) => {
    console.log(acc);
    web3.eth.personal.unlockAccount(acc[0], "qwer1234", 1500)
    .then(res => {
        if (res === true) {
            web3.eth.sendTransaction({
                from: acc[0],
                to: acc[1],
                value: web3.utils.toWei(0.1, "ether")
            })
            .then(console.log)
        }
    });
});

Best Answer

Before running this process, you will start before 5 min because it will increase the speed of mining process. To start mining run:-

miner.start() before compiling node js where api are created.
