+## 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.
