When the Oracle Speaks: Fenbi's $83M Loss and the Decentralized Governance Imperative

The most dangerous promise in education is certainty. At Renmin University last month, Fenbi’s CEO offered a different kind of certainty—stock market gains. Standing before a room of civil service exam aspirants, he changed the scheduled lecture topic from exam preparation to AI and stock trading. He told the students he had made 53 million yuan in a single month by trading stocks. He urged them to “let your whole family trade together.” The students sat in cold silence. Frustrated, the CEO lashed out, called them ungrateful, and walked off stage. Hours later, he posted antisemitic remarks on Weibo. That outburst, however, was merely the shadow of a larger collapse. Two weeks later, Fenbi—a leading Chinese exam prep company—disclosed in its earnings preview that it had recorded an 830 million yuan ($115 million) investment loss from stock trading. The company’s stock promptly fell 17% to an all-time low. The CEO resigned. The fairy tale of certainty had shattered. Fenbi’s business model is built on prepaid tuition—students and their families pay upfront for courses that promise a stable government job. The company holds billions in deferred revenue, a pool of trust that should be ring-fenced for operational expenses and refunds. Instead, that trust was gambled away by a CEO who saw himself as a market oracle. The company’s year-end securities portfolio was worth only $117 million, meaning more than 80% of that portfolio was wiped out. This is not just a story of poor risk management. It is a story of centralized governance failure. Fenbi had a board of directors, auditors, and presumably internal controls. Yet one man—the founder and CEO—was able to steer corporate funds into speculative trades, boast about his prowess to the very customers who funded those trades, and then resign after the damage was done. The students who paid for exam preparation effectively subsidized a high-stakes casino. Their trust was encoded in a contract, not a covenant. From my work auditing DAO treasuries, I have seen the opposite experiment. In well-designed decentralized organizations, treasury allocations often require multi-sig approval, timelocks, and community votes. A single actor cannot wire millions into a personal brokerage account without on-chain transparency. When I audit a DAO, I look for the smart contract logic that governs capital deployment. It is not perfect—DAOs can be captured by whales or paralyzed by apathy—but the key difference is that in a DAO, the rules are visible and programmable. Any extraction must leave a trace on the ledger. Fenbi’s CEO acted as an unappointed decentralized oracle—he claimed to predict market gains with near-absolute confidence. In blockchain, we know that oracles are the weakest link. If the oracle is compromised, the entire system collapses. Here, the oracle was the CEO’s ego. The company’s financial statements were up to date, but the governance oracle—the system of checks and balances—was silent. The market punished the stock, but the real loss was borne by the students who will never see that tuition money again. My code was the covenant, not just the contract. That line comes from my earliest days auditing Uniswap V2. I realized that smart contracts could enforce not just execution but intention. Fenbi’s contract with its students was to deliver a service—exam prep. The CEO broke that covenant when he redirected capital away from that service. A smart contract could have enforced a rule: “No more than 5% of deferred revenue may be allocated to securities trading.” It could have paused the trade if the loss exceeded a threshold. It could have required a board vote for any deviation. None of that existed. The contract was a piece of paper, not a line of code. The contrarian truth is that decentralization is not a magic shield. I have seen DAOs lose millions to governance attacks where a majority voted to drain a treasury for illiquid NFTs. I have seen multi-sig holders collude to bypass timelocks. The Fenbi case reminds us that the absence of centralized authority does not automatically create trust. What matters is alignment of incentives and transparency. In the silence of the bear, we heard the truth. The bear market of 2022 taught me that when prices fall, the structure of governance is stress-tested. Fenbi’s stock collapse was a stress test that revealed a brittle framework. The CEO’s behavior—bragging about gains then hiding losses—is identical to a DeFi rug pull. The difference is that in crypto, the entire community can see the transaction history on Etherscan. Fenbi’s transaction history is buried in private brokerage accounts. The web3 world should not gloat. We must recognize that many crypto projects suffer from the same single-point-of-failure: a charismatic founder who controls the treasury keys. The solution is not to replace a CEO with a multi-sig but to embed governance explicitly in code. We need to design systems where the steward cannot act alone, where every movement of capital is auditable by default, and where the covenant between user and protocol is written in smart contracts. Every broken token taught me how to hold value. I learned this when I watched a friend’s yield farm collapse because the dev team could mint unlimited tokens. The token itself was a broken promise. Fenbi’s share price is now a token of broken trust. But unlike a cryptocurrency, it cannot be upgraded with a hard fork. The students and shareholders are left with a centralized mess. Let this be a lesson for every founder in both traditional and decentralized finance: trust is not a given; it must be encoded. The CEO who believes he is an oracle will eventually be contradicted by the market. The board that provides no oversight is a phantom. The students who paid for certainty deserved a system that could not be betrayed by one man’s hubris. We build in the noise to find the signal. The signal from Fenbi’s collapse is that governance must be resilient to the worst-case scenario—not just the average case. Whether you are building an education company or a DeFi protocol, the challenge is the same: how do you protect users from the very people they trust? The answer lies not in eliminating trust but in distributing it. In writing it into code. In making the covenant as immutable as the blockchain itself.
