This is small but shows the power of Chainlink if you can imagine the possibilities. Most of it is the contract code examples provided on Chainlink's site

>What does the contract do?
It gets price data from the CoinMarketCap adapter (https://docs.chain.link/docs/coinmarketcap)) that chainlink provides, and stores the price in the contract for all to view.

>What do I need to check it out?
Switch metamask to ropsten test network and get some free ETH from a faucet:
https://faucet.ropsten.be/
https://faucet.metamask.io/
http://faucet.bitfwd.xyz/

Once you have the test ETH, head to https://myetherwallet.com and make sure to switch it to the "Ropsten network (myetherwallet)" (top right corner drop down box).
1. Click on Contracts page
2. Input contract address: 0x92c9ae02b962c7a1da9c1ec3f3c0569edb9ba725
3. Paste the ABI/JSON interface from here: https://pastebin.com/7PXyKzMA
4. Click Access

Now you can select the different functions from the drop down box. If you select "latest_price" this will show you the price of whichever currency pairing that was saved since the last request (it was ETH/USD when making this post).

I have loaded up the contract with 30 test LINK's so now to get the contract to download the price you do this:

1. Choose "requestCoinMarketCapPrice" from drop down box.
2. Put "ETH" (without quotes) into the _coin box and "USD" into the _market box
3. Click Write and finish the transaction using MetaMask
4. Once it is complete, go back to the "latest_price" and it should have the new price

You can use any currency that CMC lists (try BTC and KRW for example).

OK THANKS guys this was my first time learning Solidity and this Chainlink is really impressing me so far.

Link is shit and you don't even know the basics of solidity. I bet there isn't a single linker here who is capable of designing an even semi complex contract.

Oh look, another racist nazi cultist comes out of the woodworks.

this is just an example. for serious applications you would pull price data from many different sources as well as using many oracles to make sure the data is legit.

>he thinks professors are smart
professors come in 3 categories
A) A students who are retarded outside of academics and decided to get a PHD after failing to find a job
B) diversity hires
C) old guys who decided they'd like to teach the youth after retiring from successful careers

guess which one of those 3 is actually smart, and which one is the most likely to be conservative
