Cryptocurrency hack-a-thon-o-rama weekend project.
Make an Ethereum Dapp written in Solidity.
# 1. install truffle cli
npm install -g truffle
# 2. start truffle develop ethereum client
truffle develop
# 3. in a new console: compile Dapp
truffle compile
# 4. deploy migration
truffle migrate --reset --network developmentIn addition to truffle develop there are other options for Ethereum Clients both development and real:
# stand alone local test client
docker run --rm -it -p 8545:8545 trufflesuite/ganache-cliDocker
# Note you could also use --rinkeby instead of --testnet (ropsten?)
# This will persist your configuration in ~/.ethereum (might need to set permissions properly)

# Setup a new account
docker run --rm -it \
-v "$HOME":/root \
ethereum/client-go:stable \
--rinkeby account new
# Connect a console
docker run --rm -it \
