Binance Founder Proposes On-Chain Dark Pool DEX for Futures Trading

Binance founder Changpeng Zhao, commonly known as CZ, has proposed the creation of an on-chain dark pool decentralized exchange (DEX) for cryptocurrency futures trading. This proposal comes in the wake of significant market manipulation incidents, notably the $100 million loss suffered by trader James Wynn due to liquidations on high-leverage Bitcoin positions.

CZ's proposal, made on the social media platform X (formerly Twitter), underscores the growing concerns about privacy and market manipulation within the current DEX ecosystem. He highlighted that the real-time visibility of trades on existing DEX platforms creates vulnerabilities for front-running and maximal extractable value (MEV) attacks. These attacks allow observers to exploit visible orders to execute trades ahead of large buyers, thereby manipulating the market to their advantage.

This transparency issue is particularly problematic in perpetual futures trading, where liquidation points are publicly visible. This visibility can lead to coordinated efforts to push prices and trigger liquidations, as CZ noted, "If others can see your liquidation point, they could try to push the market to liquidate you. Even if you got a billion dollars, others can gang up on you."

CZ suggested that a dark pool DEX could mitigate these issues by concealing order books and using zero-knowledge proofs to ensure privacy. This approach would protect traders from front-running and MEV attacks, providing a more secure and private trading environment. The proposal has garnered positive responses from experts in the field, who believe it could enable institutional-grade DeFi trading.

In traditional finance, large traders often use dark pools—private trading venues that hide order details—to protect their trading strategies. CZ believes a similar approach could benefit crypto traders by reducing slippage, improving prices, and lowering costs. The proposed dark pool DEX would need to conceal order books or delay the visibility of deposits into smart contracts, leveraging advanced cryptographic techniques like zero-knowledge proofs to ensure secure and private transactions.

Experts suggest that building such a platform would require full decentralization, cross-chain interoperability, and trustless execution. Potential solutions include using "atomic swaps" with "Hash Time Lock Contracts," which are smart contract mechanisms that enable two parties to trade assets across blockchains only if specific conditions are met within a time limit. Otherwise, the transaction is canceled and funds returned to both parties.

CZ, who stepped down as Binance CEO in 2023, has invited developers to contact him via ReachMe.io, a paid messaging platform he introduced in March to filter out spam and manage high volumes of inbound messages. The first company to build a successful dark pool DEX could set the standard for private DeFi trading and potentially unlock new opportunities for institutional investors in the cryptocurrency space.
