## chainlink
<br>
A decentralized oracle network consisting of three key smart contracts:
* a reputation contract: keep track of data providers' performance.
* an order-matching contract: selects bids from oracles using the reputation contract.
* an aggregation contract—and an off-chain registry of data providers.
One of the main challenges with such a decentralized approach is the formulation of the aggregation function.
ChainLink proposes calculating a weighted response, allowing a validity score to be reported for each oracle response.
