CHAINLINK DATA FEEDS ENSURE HIGHLY RELIABLE MARKET DATA


1

First, premium data providers aggregate raw price data from a multitude of
centralized and decentralized exchanges, accounting for time, volume, and
outliers.

2

Next, independent Chainlink nodes fetch market price data from various premium
data providers and combine the results into an aggregated value.

3

Lastly, multiple Chainlink nodes aggregate their results together off-chain to
generate a tamper-resistant oracle report, which is made available to smart
contracts. 


EXTENSIVE MONITORING OF YOUR SMART CONTRACT DATA FEEDS

Numerous tools built with the help of the Chainlink ecosystem provide full
visibility into data feeds and the teams participating in them.
