Go & Ethereum exploration and prototyping

Go and Ethereum exploration. It starts with https://goethereumbook.org/en/client-setup/

Setup

If running locally, we assume a ganache server is running:

ganache -m "hole symptom crater bring army industry link later fabric hotel asthma pupil"

You will also need to use an infura API key, create a secrets.json file that looks like the following:

{
  "infura": "your API key here",
}

Running the scripts

To run the remote client, simply compile and run: go run .. If you want to run against a local ganache client, run go run . -local.

You can also deploy the contract (if running locally, by passing -deploy). The full usage is below:

Usage of goreth:
  -deploy
    	a flag that, if passed, deploys the Storage contract
  -local
    	a flag that, if passed, runs the script locally

Appendix: compiling solidity contracts

We have solidity contracts in the contracts/ folder. To work with contracts, you'll need to install abigen (a devtool packaged in go-ethereum), and solidity:

brew install ethereum
brew install solidity

Then, you can generate the ABI of a contract, compile it, and generate go bindings with the respective 3 commands:

solc --abi Store.sol
solc --bin Store.sol
abigen --bin=Store_sol_Store.bin --abi=Store_sol_Store.abi --pkg=store --out=Store.go
