Push-Based Oracle

Overview

In a push-based oracle model, publishers or an oracle network monitor sources and submit reports without waiting for each consumer transaction. Contracts can then read the latest stored value through a stable interface.

Update conditions balance freshness and cost. Deviation thresholds respond to market movement, while heartbeats refresh quiet feeds. Congestion, insufficient reporter incentives, or destination-chain problems can delay publication even when sources continue operating. Consumers must still verify the feed address, timestamp, round or sequence, decimals, confidence, and acceptable age. Reading a contract successfully does not prove the value is fresh or suitable. Applications should monitor missed updates and define fallback or pause behavior. Push delivery simplifies reads but cannot guarantee continuous liveness. This distinction is essential when a technically valid oracle message produces an economically incorrect payment, liquidation, or release decision. Operational records should retain the exact report, block reference, source configuration, and rule that consumed it.

Push-Based Oracle should specify the reported value or event, authorized sources, aggregation method, update trigger, timestamp, decimals, and validity conditions. On-chain authenticity does not guarantee freshness, correct units, or fitness for a particular business action. Multiple reporters do not create independence when they rely on the same exchange, API, infrastructure provider, or market methodology. The trust model includes data providers, node operators, signers, transmitters, contracts, governance, and any emergency controls. Integrations should enforce freshness and deviation limits, validate the expected feed or contract, and define fallback behavior for missing, disputed, or implausible data. High-value actions may require delayed execution, secondary evidence, or a circuit breaker rather than automatic acceptance.
