Attestation: proving the asset is there, and pledged once

Graduate · enrolled learners

This lesson opens with The salad-oil swindle, 1963.

What happened

A trader named Anthony De Angelis ran a company that claimed to hold enormous quantities of vegetable oil in storage tanks in New Jersey, and it used warehouse receipts for that oil as collateral to raise money from lenders and brokers, at least 180 million dollars. The receipts were issued by a warehousing company that controlled the tanks at Bayonne, and the tanks were inspected, and inspectors found oil, so the receipts were attested as backed. But De Angelis filled some of his tanks with water, leaving only a thin film of oil on top in case of inspection, because oil floats, and millions of dollars of receipts were issued for oil that was not in the tanks at all. The attestation checked appearance, is there oil at the top of the tank, not substance, is the tank actually full of oil, and appearance was exactly what the fraud produced. When it unraveled in 1963, the oil was not there, the receipts backed far less than they claimed, the brokerage Ira Haupt and Co. went bankrupt, and American Express, whose warehousing business had issued receipts, was exposed. The attestation existed and certified an asset that was largely water.

The decision point

An attestation is a verification that an asset is there, but it certifies only what it actually checks, and it is only as good as the rigor of that check. A superficial attestation, one that confirms appearance rather than substance, can certify an asset that is not really there, because it verifies the thing the fraud is designed to produce and not the thing that matters. The salad-oil swindle is the case: inspectors who dipped tanks and found oil on the surface attested to oil that was largely water, because the check tested for the appearance of oil, which a film of oil floating over water trivially supplied. For a tokenized real-world asset, attestation is what makes the receipt-to-asset link verifiable to holders, but only if it actually verifies what matters: that the asset genuinely exists, in the claimed quantity, and is pledged to this token and no other, rather than confirming a surface that a determined party can fake. So the decision when structuring or relying on a tokenized asset is to demand attestation designed to defeat the fraud it is meant to catch, verifying existence, quantity, and sole pledge with rigor, independence and unpredictability, because an attestation that checks appearance is worse than none, since it lends false confidence to an asset that may be, like De Angelis's tanks, largely water.
