How Does a PoR Oracle Differ from a Standard Price Oracle?
A standard price oracle reports the market trading price of an asset, which is a dynamic, market-driven value. A Proof-of-Reserve (PoR) oracle, conversely, reports a static, verifiable quantity: the amount of a specific asset held in reserve by an issuer.
The PoR oracle's function is to prove solvency and backing, not to provide a market price. It is a verification tool rather than a price discovery tool.
