2 Blockchain local testnet

2.1 Set up a Private Ethereum Blockchain

Use this tutorial: https://media.consensys.net/how-to-build-a-private-ethereum-blockchain-fbf3904f337, or use the dockerized version: https://github.com/Capgemini-AIE/ethereum-docker.

Example of genesis.json: https://gist.github.com/dickolsson/e652b3d0e7bee55aa0a582d8a03900bf.

2.2 Install MetaMask in your browser

https://metamask.io/

2.3 Connection

Now connect to de local testnet with MetaMask using assigned port in ´--rpcport´ command. Note: It's nessesary initialize the nodes with the parameter --rpc and if you want to connect with other nodes, this parameter must setted --rpcaddr 0.0.0.0.

3 Smart contract

Read the Ethereum documentation: http://www.ethdocs.org/en/latest/.

To introduce on smart contracts and Dapps, see this videos from 1 to 10 and 20:
