Cryptocurrency hack-a-thon-o-rama weekend project.
## Goal
Make an Ethereum `Dapp` written in `Solidity`.
## Quickstart
```bash
# 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 development
```
## Ethereum Clients
In addition to `truffle develop` there are other options for Ethereum Clients both development and real:
### Ganache
```bash
# stand alone local test client
docker run --rm -it -p 8545:8545 trufflesuite/ganache-cli
```
### Ethereum Testnet:
Docker
```bash
# Note you could also use --rinkeby instead of --testnet (ropsten?)
# This will persist your configuration in ~/.ethereum (might need to set permissions properly)
# https://github.com/ethereum/go-ethereum#full-node-on-the-ethereum-test-network
# Setup a new account
docker run --rm -it \
-v "$HOME":/root \
ethereum/client-go:stable \
--rinkeby account new
# Connect a console
docker run --rm -it \
-v "$HOME":/root \
-p 8080:8080 \
-p 8545:8545 \
-p 8546:8546 \
-p 30303:30303 \
-p 30304:30304 \
ethereum/client-go:stable \
--rinkeby \
--fast \
--cache=512 \
--rpc \
--rpcaddr localhost \
--rpcport 8545 \
--rpccorsdomain "*" \
--ws \
--wsport 8546 \
--wsorigins "*" \
--rpcapi eth,net,web3,personal \
console
# to exit
# some commands:
> net.listening
> net.peerCount
> admin.peers
> admin.nodeInfo
> eth.accounts # list accounts
> eth # all eth commands
> web3 # all web3 commands
> personal # all personal commands
> personal.unlockAccount(eth.accounts[0]) # unlock 1st account
> web3.personal.unlockAccount(web3.personal.listAccounts[0]) # unlock web3 account
> eth.getBalance(eth.coinbase) # get balance in Ethercoin
```
Geth & Rinkeby
```bash
# Create a new account
geth --rinkeby account new
# Start a Rinkeby client
geth --rinkeby --fast --cache=1024 --rpc --rpcapi eth,net,web3,personal
# Attach a console to the client
geth --datadir=$HOME/.ethereum/rinkeby attach ipc:$HOME/.ethereum/rinkeby/geth.ipc console
```
### Ethereum Real Network:
```bash
# just remove --testnet or --rinkeby from previous command
```
## Currency Units
```bash
1: wei (smallest atomic unit of currency)
10^3: (Kwei (kilowei))
10^6: (Mwei (megawei))
10^9: (Gwei (gigawei))
10^12: szabo
10^15: finney
10^18: ether
10^18 wei = 1 ether
```
## MoneyMoneyMoneyMoney
* `truffle migrate -f 2 --network rinkeby`
* Copy abi from ./build/contracts/Money.json
* Get rid of the newlines and new paragraphs [using this tool](https://www.textfixer.com/tools/remove-line-breaks.php)
* On your geth console:
* `var abi = `
* `var money_contract = web3.eth.contract(abi)`
* `var money_inst = money_contract.at('')`
## Web
```bash
cd web
yarn install npm install --save
npm start
```
