Hello!
I will demonstrate quickly and directly how to create a contract and your Javascript client in Ethereum's Blockchain!
First let's install the Ethereum Geth client (https://github.com/ethereum/go-ethereum).
To do this in Linux run the following command:
sudo apt-get install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum
Instantiate your node in development mode and accessing the console:
geth --dev --ipcpath ~/.ethereum/geth_test.ipc console --rpc --rpccorsdomain "http://localhost,http://ethereum.github.io" --rpcapi="db,eth,net,web3,personal"
Create the master account in the ethereum console
personal.newAccount()
Minimize a little to generate the money needed to make the deploy:
miner.start()
Stop mining
wait a few seconds and you can stop on the console itself:
miner.stop()
Deploy the contract using the remix (http://ethereum.github.io/browser-solidity)
Good! I am learning to configure this blog, if you want me to conclude this article please comment, that I will detail and improve this post with details and who knows even a video !!!!
