In the given Ethereum virtual machine VM ware image, the required/supporting software was
installed.
Step 1: Open the terminal and create a test folder
$mkdir eth-test
Step 2: Go the newly created folder
$cd eth-test
Step 3: Create user accounts using geth command
$geth account new --datadir ~/node_1
Running of this command will ask you to enter a password. This password
(passphrase) is must to remember.
Once the password is entered an user account will be created by generating a hash
address as follows
Address: {3c3be55cab52db2021201d8b5f00de54ad226364}
Step 4: Create another user using geth command
$geth account new --datadir ~/node_2
Further steps after this command are similar to Step 3.
Step 5: Since any peer in the Blockchain network creates blocks based on Genesis block,
let us create a genesis block for newly created nodes 1 and 2. To do this move to the
folder node_1 first
$cd node_1
and create a json file with the name customGenesis.json
Step 6: Copy the following content into the newly created customGenesis.json file
{
"config": {
"chainId": 12102018,
"homesteadBlock": 0,
"eip155Block": 0,
"eip158Block": 0
},
"difficulty": "0x20000",
"gasLimit": "0x2fefd8",
"alloc": {},
"nonce": "0x0000000000000042",
"timestamp": "0x0",
"parentHash":
"0x0000000000000000000000000000000000000000000000000000000000000000",
"extraData": "",
"mixhash":
"0x0000000000000000000000000000000000000000000000000000000000000000",
"coinbase": "0x0000000000000000000000000000000000000000"
Step 7: Now come out of the node_1 and intialize the genesis block
$cd ..
$geth --datadir ./node_1 init ./node_1/customGenesis.json
Step 8: Repeat the step 5 to 7 for node_2 also
Step 9: geth --datadir ~/Node_1 --maxpeers 95 --networkid 13 --nodiscover --rpc
--rpccorsdomain "*" --port 30301 --rpcport 8544 --
