Solidity Programming setup
- Install Xcode
- Open xcode to accept the license agreement.
- Close xcode
- Open terminal
xcode-select --install
this will install command line tools, which is needed to install homebrew
- Install homebrew
- Go to Brew sh
- Copy and paste script from brew into terminal
- Install Geth
brew update // update catalog brew tap ethereum/ethereum // add the ethereum repository to catalog brew install ethereum
To upgrade an existing installation
brew upgrade ethereum
- Install Ganache Ganache
- New version has a bug so install Ganache Version 1
- Ganache is like testrpc
- Install NodeJs NodeJs
- This installation will also upgrade older versions
- On a new system you can use
brew install node
- Install Truffle4 Truffle Framework
sudo npm install truffle
- If you have older version YOU MUST REMOVE IT
npm uninstall -g truffle
Setting up the Ethereum Node
- Create Folders
mkdir -p ~/ChainSkills/private
- Define Genesis Block ( run from the private Directory)
puppeth
- Network Name
- whatevername
- Option 2 to configure new genesis
- Option 1 (Ethash proof of work)
- Which account to be funded
- Just Hit Enter
- Specify your chain/network id
- 4224 (has to be different for the other networks)
- What would you like to do
- Option 2 (manage existing genesis)
- OPtion 2 (export genesis Config)
- Accept default filename
- Ctrl C to Quit
Initialize Private Node
Must be in the Private Directory
geth --datadir ~/ChainSkills/private init chainskills.json
Prepare for Mining
Create some accounts ( make sure you are in the private directory) run multiple times to create more accounts
geth --datadir . account new // create password the . means current directory
Accounts are stored in an array [0], [1] Etc. List accounts
geth --datadir . account list
Create a Script to Start the Mining Node
This must be on one line startnode.sh do chmod +x to make it executable
geth --networkid 4224 --mine --minerthreads 1 --datadir "~/ChainSkills/private" --nodiscover --rpc --rpcport "8545" --port "30303" --rpccorsdomain "*" --nat "any" --rpcapi eth,web3,personal,net --unlock 0 --password ~/ChainSkills/private/password.sec --ipcpath "~/Library/Ethereum/geth.ipc"
Create the password.sec file and add your password to the file then save it
Start The node
./startnode.sh
Connect to the node when mining starts
- Open new terminal winow
geth attach
Some commands
eth.accounts // list accounts eth.coinbase // get a specific account eth.getBalance(eth.accounts[1]) web3.fromWei(eth.getBalance(eth.coinbase),"ether") // convert wei to ether miner.stop // stop mine process miner.start(2) // start miner using 2 threads net.version // network identifier personal.unlockAccount(eth.accounts[1], "outwater", 300) // unlock account makes the private key available for signing transactions for sending trans
Transfer funds between accounts
eth.sendTransaction({from: eth.coinbase, to: eth.accounts[1], value: web3.toWei(10, "ether)})
Type Exit to quit
