>What is Chainlink?
Chainlink is a decentralized network of oracles reliably inputting data to smart contracts.
>What is the LINK token and why do I want to buy it?
The LINK token is what Oracle operators require to operate. Operators lock away huge stacks of LINK in their Oracles because the more they lock away, the pricier the contract they can submit info to.
>Why don't Oracle operators just get paid in USD?
Because the network runs on LINK tokens. The more usage the network gets, the pricier each token becomes.
>How do I buy LINK tokens?
Currently you can only buy LINK from cryptocurrency exchanges, but soon there will be official, direct gateways to convert USD/LINK, EURO/LINK, ETC.
>What are oracles and why do we need them?
Oracles and their operators are what and how the flow of constant information is submitted to the Chainlink network.
>What information do I submit?
Information you are tasked to submit.
>How are oracles decentralized?
Decentralized means anyone, not a select few, can run an Oracle and upload information. A reputation system is built in that punishes niggers who submit bad information, and rewards people who submit true information.
>What decides the information I submitted is true?
The network decides, based on majority rule, which is effectively the only way to decide. Based on the reward/punishment system in the previous question, operators who take their job seriously won't risk losing it over being persuaded to upload wrong information.
>What are smart contracts?
Automatically executing digital contracts, which will replace future legal agreements, where a contract executes on its own instead being executed by either party in the contract.
>How does the contract know when to execute?
When conditions in the contract are fulfilled, the contract executes.
>Who does Chainlink benefit?
You buy now, and get rich when the network takes off, and every mega corporation will save billions of dollars in payments, claims processes, etc.
