Last week, a friend was liquidated on a certain lending platform. The market was actually quite stable, but suddenly the oracle fed an outrageous price, directly wiping out his position. When he filed a complaint, he realized—no one could clearly explain where that price came from. He chuckled and said, "It seems that the most money-burning part of the chain isn't really the Gas fee, but the cost of these 'unclear' data."

After hearing this story, I finally understood that the real risk in blockchain isn't whether the code has bugs, but that— the data itself might be fake.

Do you remember the childhood game "Chinese Whispers"? A sentence is whispered around a circle, and by the end, it’s completely changed. Nowadays, blockchain applications are pretty much stuck at this point—smart contract logic might be flawless, but the data fed into it has long been unrecognizable.

Let's review some of our most frustrating losses. Are there cases like these: the market doesn't move at all, yet the liquidation level is directly breached by some inexplicably low price? During cross-chain operations, the price data from Chain A and Chain B don't match, causing assets to be stuck or systems to misjudge? The prediction market clearly won, but the results are announced as "disputed," and the rewards never arrive?

These issues seem diverse, but at their core, they all stem from the same problem—key decisions on the chain rely on those mysterious, untraceable, unaccountable "black box data" sources.

Traditional oracles are a bit like mailmen—they deliver the message, and that's it. It doesn't matter what the content is. If we could truly achieve full traceability across the entire chain, verify every step, and hold each part accountable—from data source all the way to contract execution—that would be the real solution to this problem.
