Ethereum represents one of the most interesting technological developments in the past few years, taking the fundamental principles of a blockchain, and allowing executable “contracts” to be written. These contracts can be relatively simple but also incredibly powerful.
Parity is a fast Ethereum browser, a tool which allows you to interact with the blockchain. On my laptop at least, it is significantly faster to synchronise and use than geth, which is probably the “standard” tool for interacting with the Ethereum blockchain.
bash <(curl https://get.parity.io -Lk)Connecting to the Ropsten testnet
To run Parity and connect to the testnet, use the following command:
parity — chain=ropsten
You’ll see a stream of stuff fly by in the terminal as Parity connects to the testnet, and starts the process of synchronising the blockchain. This might take a while…but rest assured it’s much faster than using the Ethereum Wallet app.
While you wait, you can still get started using Parity through its lovely web interface.Setting up Parity
Parity comes with a really nice, fully featured web interface. This allows you to view and create wallets (where you keep your Ether), interact with other apps and to create or interact with Contracts.
By default, the parity web interface should be available at http://127.0.0.1:8180
