Binance co-founder Changpeng Zhao has recently put forward an intriguing proposal for the development of a dark pool-style decentralized exchange catering to perpetual contracts. In a recent post on X, he expressed his concerns regarding the risks associated with full transparency in on-chain trading. CZ believes that the current climate presents an opportune moment for the creation of a more private and secure trading solution.
The impetus for CZ’s comments can be traced back to a significant liquidation event involving $100 million in Bitcoin long positions on Hyperliquid, reportedly orchestrated by trader James Wynn. This incident, which unfolded following Bitcoin’s dip below $105,000, ignited suspicions on X that certain users may have colluded to trigger Wynn’s liquidation.
CZ highlighted his longstanding skepticism surrounding the practice of decentralized exchanges disclosing real-time visibility of user orders. While transparency is a cornerstone of DeFi, he contended that it places large traders at a distinct disadvantage. “If you’re looking to make a substantial investment of $1 billion in a particular coin, you wouldn’t want others to anticipate your moves,” he elaborated. “There’s a risk of individuals front-running your transactions by purchasing before you.”
The perils are exacerbated on perp DEXs, where traders’ liquidation thresholds are often publicized on-chain. CZ cautioned that this setup could pave the way for market manipulation and orchestrated liquidations, particularly targeting heavily leveraged positions. In conventional finance, institutional traders circumvent such risks by leveraging dark pools, secluded exchanges that facilitate large trades without broadcasting them on the public order book. CZ revealed that dark pool volumes tend to be ten times larger than those of conventional “lit” public exchanges.
Even centralized cryptocurrency exchanges offer a higher degree of confidentiality than DEXs, as order books are not linked to identifiable wallet addresses. This veil of anonymity serves as a deterrent against targeted attacks.
Proposing a solution to address these concerns, CZ floated the idea of establishing a dark pool perpetual DEX utilizing privacy technologies like zero-knowledge (ZK) proofs. This concept could involve concealing the order book or delaying the revelation of smart contract deposits. “A dark pool-style DEX for perpetual contracts, whether by concealing the order book or, ideally, not disclosing smart contract deposits at all, or until a significant delay has transpired. This could be executed using ZK or analogous encryption methods,” he outlined.
CZ underscored that the objective is not to diminish the value of transparency. Recognizing that some traders and market makers might favor public data for enhanced liquidity and order absorption, he stressed the importance of catering to the diverse needs of market participants.
In closing, CZ extended an invitation to developers interested in pursuing such a project to reach out to him, albeit with no assurances of investment or immediate response. “This is merely a concept pondered on a Sunday,” he clarified.
The proposition resonated with users who echoed similar apprehensions. One user suggested leveraging ZK rollups on a Layer 2 network to actualize the proposed solution, to which CZ responded, “That’s one conceivable approach. There exists a myriad of potential technological solutions.”
In essence, CZ’s proposal for a Dark Pool Perp DEX stands as a proactive measure aimed at mitigating the risks of market manipulation, heralding a potential shift towards a more secure and confidential trading landscape in the realm of decentralized finance.
