Well, Devil is in the details but getting started is actually simple. Kudos to the Ethereum developers.
Let's setup a new fully synced Rinkeby (Ethereum test network using Clique PoA protocol) node.
Rinkeby PoA implementation is much faster but significantly less secure, more centralised from the mainnet concensus PoW. Rinkeby manages to approve a new block every 15s.
Wou wou wou. What those words actually mean?
You can read more about the Rinkeby PoA proposal here: https://github.com/ethereum/EIPs/issues/225
The above command will:
Wait for few hours until the blockchain is fully synced. You will have to download ~20GB of ledger history. Current block number is: 3039786. On my AMD Ryzen 5 2600, 3.4Ghz the sync process took 3 hours. Meanwhile you can follow GophersLand on Twitter, tell your friends about it, checkout our Medium Blog or prepare a dinner, probably breakfast as well, go to gym... let's just say, blockchain is not the fastest database :)
Eventually the printed message will be:
Congratulation, you are now part of the blockchain revolution in less than 10mins!!!
