Imagine a scenario: a hacker compromises the validation nodes of a cross-chain bridge, causing the on-chain BTCB to enter a strange state—before anyone makes large withdrawals, the ledger shows 100% reserves; but once someone actually attempts to withdraw, the wave function collapses, and reserves could instantly drop to zero. This is the "Schrödinger's asset" problem in DeFi.

What's worse, the risk control systems of some lending protocols become quantum confused at this moment: smart contracts don't know whether to liquidate or to let it go, resulting in random oscillations—sometimes deciding you are liquidated, sometimes deeming you safe. Your position fluctuates wildly within this uncertain black box.

Traditional finance tolerates such "black box" scenarios through reserve systems, but DeFi must not. How to break this deadlock?

**Real-time auditing is key.** Chainlink's Proof of Reserve oracle can monitor off-chain or cross-chain assets in real time. As soon as native reserves decline, the oracle immediately triggers a contract to pause lending—turning manual "observation" into automated monitoring.

**Another simple principle: reject black box collateral.** If an LST or new asset lacks on-chain real-time reserve proof, it remains in a "superposition"—do not touch. Asset transparency and auditing mechanisms are the stabilizing anchors of DeFi.
