There is a long-standing overlooked issue in Web3 infrastructure — I call it the "Lazy Oracle Economy."

The first-generation oracles (represented by Chainlink) operate with a blunt logic: they mechanically push price updates at fixed time intervals or when price fluctuations exceed a threshold. It's like subscribing to a newspaper: the mailman delivers it punctually every day regardless of whether you read it, and you pay a hefty delivery fee. In the context of blockchain, oracle nodes, regardless of transaction activity, must regularly initiate on-chain transactions to update feed data.

How serious is the problem? During periods of high Ethereum Gas fees, a single oracle update can burn dozens of dollars. To maintain price feeds for a few mainstream assets, DeFi protocols might spend tens of thousands of dollars daily — with 90% of these updates not being used in any actual transactions. This inefficient supply-side model directly erodes the profitability of DeFi protocols.

If oracles cannot address the cost issue, large-scale commercialization of DeFi will remain a pipe dream. This is a pain point, and it’s also why innovative projects like APRO are beginning to explore "Pull" models rather than "Push" — shifting the decision-making for price updates to the actual demand side of transactions. This is not just a simple technical change, but a rethinking of the entire oracle economic system.
