How to build VPC for Geth in Block chain
Today, I will talk to you about how to build a private network in Geth in the blockchain, which may not be well understood by many people. In order to make you understand better, the editor has summarized the following contents for you. I hope you can get something from this article.
[Windows] step 1:
Create a directory tmpPrivate
Create a genesis.json file and write the following
{"config": {"chainId": 15, "homesteadBlock": 0, "eip155Block": 0, "eip158Block": 0}, "coinbase": "0x0000000000000000000000000000000000000000", "difficulty": "0x40000", "extraData": "", "gasLimit": "0xffffffff", "nonce": "0x0000000000000042", "mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000" "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000", "timestamp": "0x00", "alloc": {} step 2:
CMD enters tmpPrivate, executes commands, and creates Genesis Block.
Geth-- datadir ". /" init genesis.json
At this point, you can notice that two new folders geth and keystore will be added under the current directory.
What is saved in geth is the data related to the block chain.
What is saved in keystore is the user information in the chain.
Step 3:
Create your own private chain
Geth-datadir ". /"-nodiscover console 2 > > geth.log
Console2 > > geth.log means to output part of the console to the file geth.log
Step 4:
Create users on your own private chain
Eth.accounts
The return value is [] because the private chain of Ethernet Fong is created, but there is no account.
Create a new user
Personal.newAccount ("123456")
"123456" is the user's password
You can create several
Step 5:
Start / stop (start digging)
Miner.start () miner.stop ()
Check the account
Eth.accountspersonal.listAccounts
View individual account balance
Eth.getBalance (eth.accounts [0])
Or:
Acc0=eth.accounts [0] eth.getBalance (acc0) after reading the above, do you have any further understanding of how to build a VPC in Geth in the blockchain? If you want to know more knowledge or related content, please follow the industry information channel, thank you for your support.
