## Aggregator Nodes

Aggregator nodes are specialized participants in an oracle network that collect data from multiple independent sources, calculate a representative value, and submit it to the blockchain. By centralizing the aggregation process before the data reaches the smart contract, these nodes simplify the task for the protocol and reduce the cost of on-chain operations.

However, this also introduces a potential point of failure or bias if the aggregator itself is compromised. To maintain security, the aggregation process must be transparent and verifiable, often using cryptographic proofs or decentralized multi-node systems.

In derivatives markets, these nodes are critical for providing reliable price feeds that are resistant to manipulation. Their role is to bridge the gap between fragmented, noisy data sources and the structured, deterministic requirements of smart contracts.

They are essential for the effective functioning of decentralized price discovery.
