FHE - The Bridge Between Privacy and Transparency, and Why It Could Have Prevented Much of the 10/10 Losses 1. The 10/10 Event - When Excessive Transparency Led to Collapse On October 10, 2025, the crypto market witnessed a cascading liquidation worth over $20 billion across major platforms. Decentralized exchanges like Hyperliquid and Aster suffered the heaviest losses. While the immediate cause was the sharp drop in BTC and ETH prices, the deeper root cause lay in blockchain’s absolute transparency - every wallet, every position, every liquidation threshold was publicly visible. This allowed the following to happen: Whales and institutional players could easily identify “clustered liquidation zones” and deliberately push prices into those areas to trigger cascade liquidations. Trading bots exploited on-chain data to front-run liquidation transactions, worsening price slippage. The market experienced a panic cascade as traders saw large wallets being wiped out in real time. The result: billions of dollars evaporated - not due to technical failures, but because human actors exploited blockchain’s overexposure. 2. The Other Extreme - CEXs Are “Too Opaque” and Pose the Opposite Risk In contrast to fully transparent DEXs like Hyperliquid, centralized exchanges (CEXs) such as Binance, OKX, and Bybit operate under an almost complete veil of secrecy. Position data, margin details, and liquidation records are not public. Only aggregated reports (if any) or Proof of Reserves (PoR) snapshots are shared. Investors have no visibility into what actually happens behind the matching engine. This means: When markets are calm, everything appears “safe.” But in times of crisis, rumors of fraud or manipulation spread quickly - and the community has no way to verify or disprove them. Historically, CEXs have been accused of: Faking liquidity or trading volume, Manipulating prices to protect internal positions, or Delaying liquidations to favor one side of the trade. ➡️ CEXs are “safe because they’re secret,” but that safety comes at the cost of trust. 3. FHE - The Technology That Unites Two Opposing Worlds Fully Homomorphic Encryption (FHE) - a cutting-edge encryption technology pioneered by Zama - offers a potential solution to this long-standing paradox of transparency vs. privacy. How FHE works: All data (positions, collateral, liquidation thresholds, wallet balances, etc.) are fully encrypted. Algorithms, smart contracts, and oracles can compute directly on encrypted data - compare values, execute logic, and trigger events. However, no one - not the exchange, not other users, not bots - can view the underlying raw data. ➡️ This creates a new paradigm: Verifiable Privacy - data remains private but can still be cryptographically validated. 4. Real-World Applications in DeFi and CEX ♻️ In DeFi (e.g., Hyperliquid, Aave, Venus) Positions remain fully functional but completely anonymous. Whales cannot see liquidation zones, and bots cannot front-run transactions. Oracles and liquidation mechanisms still execute accurately. The result: a dramatic reduction in cascade liquidations and market-wide panic. ➡️ FHE makes DeFi less vulnerable to the dangers of excessive transparency. ♻️ In CEXs (e.g., Binance, Bybit, OKX) Exchanges can store and process all user and trading data in encrypted form. When regulators or auditors require verification, they can request controlled decryption - proving data integrity or solvency without exposing private user information. ➡️ FHE enables conditional transparency for CEXs - maintaining business confidentiality while ensuring provable honesty when necessary. 5. Conclusion The October 10, 2025 liquidation event was not just the result of price volatility - it exposed a structural flaw in how blockchain handles data transparency. Public blockchains are so transparent they can be weaponized. Centralized exchanges are so opaque they lose public trust. FHE bridges that gap. It establishes a new market standard - privacy that remains verifiable. If adopted widely, FHE could prevent many future “black swan” events like 10/10, where data itself became the weapon - rather than the foundation of transparency it was meant to be. @zama #ZamaCreatorProgram
