The document describes the steps to create a private Ethereum network with 4 nodes using the same genesis block. It details how to initialize and start each node with different ports, check connectivity between nodes, create and transfer accounts, and begin mining to generate blocks across the network. The genesis code provided specifies the initial empty state of the private network before any transactions occur.

1. 1. Create four nodes with the same genesis
a. vijay​ (​geth --datadir .ethereum/vijay init vijay-genesis.json​)
b. nexthoughts​ (​geth --datadir .ethereum/nexthoughts init vijay-genesis.json​)
c. vendetta​ (​geth --datadir .ethereum/vendetta init vijay-genesis.json​)
d. fintech​ (​geth --datadir .ethereum/fintech init vijay-genesis.json​)
e.
2. Start all 4 node with the same network and different ports
a. vijay​ ( ​geth --datadir .ethereum/vijay/ --port 30303 --networkid 1234 console
2>vijay-console.log​)
b. nexthoughts​ (​geth --datadir .ethereum/nexthoughts/ --port 30306 --networkid 1234 console
2>nexthoughts-console.log​)
c. vendetta​ (​geth --datadir .ethereum/vendetta --port 30304 --networkid 1234 console
2>vendetta-console.log​)
d. fintech​ (​geth --datadir .ethereum/fintech --port 30305 --networkid 1234 console 2>
fintech-console.log​)
