Blockchain developing often requires to run a local Blockchain client (AKA: TestChain). This is to make sure your work remains private and that any sent transaction gets a fast response.

In order to speed up the process, this repo contains all you need to spin up a local TestChain in a few minutes. Each of these chains uses PoA (Proof of Authority) as a consensus model for faster response. They all launch using provided scripts, automatically provided with accounts and passwords.

First, let’s download the test chain matching your environment from https://github.com/Nethereum/Testchains

Start a Geth chain (geth-clique-linux\, geth-clique-windows\ or geth-clique-mac\) using startgeth.bat (Windows) or startgeth.sh (Mac/Linux). The chain is setup with the Proof of Authority consensus and will start the mining process immediately.

#r "Nethereum.Web3"

First, we need to new up a web3 object for localhost:8545 (this uses RPC)

var web3 = new Nethereum.Web3.Web3();

Are we mining? (startgeth.sh|bat auto-starts mining)

var isMining = await web3.Eth.Mining.IsMining.SendRequestAsync();

List all pre-defined accounts in the devchain

var accounts = await web3.Eth.Accounts.SendRequestAsync();

Get the balance for the default account

var balance = await web3.Eth.GetBalance.SendRequestAsync("0x12890d2cce102216644c59dae5baed380d84830c");
