Circuit Breakers and Client Diversity in the Chainlink Network

The Multiple Layers of Redundancy in Chainlink Price FeedsUnderstanding Traditional and Chainlink Circuit BreakersDiversity of Chainlink Software ClientsConclusionTo ensure the highest level of reliability and tamper-resistance, Chainlink Price Feeds feature three layers of aggregationto filter out outlier data and hedge against black swan events. First, Chainlink Price Feeds source data from professional data aggregators (e.g. BraveNewCoin), which fetch market data from all trading environments (both off-chain and on-chain exchanges) to create a single, volume-adjusted market-wide average price. Second, each Chainlink oracle node pulls data from multiple data aggregators and takes the median value, ensuring each node’s individual response is resistant to API downtime and doesn’t reflect merely a single source of data. Third, the final price consumed by a smart contract represents the median value from numerous independent, security-reviewed node operator responses, preventing any single node from being a point of failure. These multiple layers of aggregation already provide an extreme level of reliability. However, the Chainlink Network also...Get price
