Contract address is not shown in rinkeby testnet etherscan

Question

I am using Getch with truffle framework and i created an account. I have Migrations and Election.sol. After i can migrate, i couldnt see it in etherscan website. Although truffle migrate --reset --network rinkeby returns saving artifacts and contract addresses, why i cant see it on website?

geth --datadir ../eth_node --nodiscover console --syncmode "fast" --rpc --rpcapi="db,eth,net,web3,personal" --cache=1024 --rpcport 8545 --rpcaddr 127.0.0.1 --networkid=4 --"allow-insecure-unlock" --mine --minerthreads 1

truffle.config

  rinkeby: {
   host: "127.0.0.1",     // Localhost (default: none)
   port: 8545,            // Standard Ethereum port (default: none)
   network_id: "4",       // Any network (default: none) (Rinkeby's id 
                             is given)
  from:"address",
  gas: 3000000  

OUTPUT:

When i use this following function

   function checkAllBalances() { 
     var i =0; 
      eth.accounts.forEach( function(e){
      console.log("  eth.accounts["+i+"]: " +  e + " \tbalance: " + 
       web3.fromWei(eth.getBalance(e), "ether") + " ether"); 
        i++; 
       })
     };

It returns balance: 79228162514.246021893543950335 ether

What is wrong in my configuration?

Election.sol

 pragma solidity 0.5.8;

 contract Election {
  // Model a Candidate
      struct Candidate {
      uint id;
      string name;
      uint voteCount;
 }

 // Read/write Candidates
 mapping(uint => Candidate) public candidates;
// Store Candidates Count
uint public candidatesCount;

 constructor() public {
  addCandidate("Candidate 1");
   addCandidate("Candidate 2");
 }

 function addCandidate (string  memory _name) private {
     candidatesCount ++;
     candidates[candidatesCount] = Candidate(candidatesCount, _name, 0);
 }

}

Migrations.sol

  pragma solidity >=0.4.21 <0.6.0;

  contract Migrations {
  address public owner;
  uint public last_completed_migration;

  constructor() public {
   owner = msg.sender;
  }

  modifier restricted() {
    if (msg.sender == owner) _;
    }

  function setCompleted(uint completed) public restricted {
    last_completed_migration = completed;
  }

   function upgrade(address new_address) public restricted {
    Migrations upgraded = Migrations(new_address);
    upgraded.setCompleted(last_completed_migration);
   }
   }

eth.getBlock(0) returns

Answer 1

You are not on the official rinkeby network. It genesis block has hash 0x6341fd3daf94b748c72ced5a5b26028f2474f5f00d824504e4fa37a75767e177.

Several other fields are different:

• nonce is 0x0000000000000000
• gasLimit 4700000
• genesis.json is much bigger

To correctly setup Rinkeby you can follow the instructions in their page https://www.rinkeby.io/#geth.
