Rinkeby is the public testnet for Ethereum. This testnet can
be used during development, testing and pre-production scenarios. I personally
use private net during development and use Rinkeby for demos.
Refer to my other blog on setting up a development private
chain: Ethereum
Dev Network
Here are the steps for setting up and connecting to Rinkeby
test chain:
Step 1: Download the latest Geth from the below URL
As I am using a windows machine, I downloaded the windows
version. Install the Geth on your machine as per the installation guide.
Step 2: Create a folder called Rinkeby which keeps the
chain data.
Step 3: Run the following command to connect to the Rinkeby
testnet
geth.exe --rinkeby --syncmode "fast"
--datadir=devchain --rpc --rpccorsdomain "*" --rpcapi
"eth,web3,personal,net,miner,admin,debug" --verbosity 0 console
Step 4: Wait for the sync to complete. The sync will
be completed based number of blocks. With the current block number 586,326 it
took about 20 mins to sync. You can check the sync status with the following
command:
eth.syncing
The above command returns either false (if syncing has not
stated or completed) or current block number. Wait for the syncing to be
completed.
Step 5: Create the user account using the javascript
console. Run personal.newAccount() and provide password when prompted
The console shows the address of the new account created.
Step 6: Verify that your account is created in the
Rinkeby by using the Rinkeby Etherscan
Step 7: Request Ether(ETH) for your newly created
account. As you see above the current ETH balance is 0. Rinkeby uses Proof of
Authority for mining. Hence you need to request Rinkeby to provide you ether.
Rinkeby has a faucet which can provide you ether. You need to periodically
request Ether using this faucet.
To prevent spam, Rinkeby faucet requires people requesting
funds have a GitHub account and create a GitHub Gist. Let’s create a GitHub
Gist with the account number as shown below:
Once the Gist is created go to the Rinkeby faucet (https://faucet.rinkeby.io/) and request
funds
Once the account is funded with your requested ethers, go to
the Etherscan and verify that the account is credited with the requested
ethers.
With these above seven steps, our Rinkeby testnet is setup
and ready to deploy smart contracts and send transactions.
