Oracle aggregation refers to the process of collecting and combining data from multiple oracles to enhance the reliability and accuracy of information used in blockchain applications. Oracles are entities that provide external data, such as market prices or weather conditions, to smart contracts. However, reliance on a single oracle can sometimes lead to inaccuracies or manipulation. By aggregating data from several oracles, a more trustworthy and consensus-driven result can be achieved.This method reduces the risk of bad data affecting smart contracts and decentralized applications, which can have significant financial implications. The aggregated data can be averaged or processed through a chosen algorithm to ensure that it reflects the consensus among the various oracles involved.In summary, oracle aggregation improves data accuracy and security, supporting the integrity of blockchain systems that depend on external information for their operations.
