Binance founder Changpeng Zhao, higher generally known as CZ, has floated the concept of a decentralized alternate (DEX) the place order books and person positions are hidden to mitigate front-running and liquidation dangers.
The decision comes amid renewed consideration to Maximal Extractable Worth (MEV), the follow of manipulating transaction ordering for revenue.
The Darkish Pool Argument
In a June 1 post on X, CZ questioned why DEXs proceed to show person orders in real-time, noting that such transparency usually invitations predatory ways like front-running and liquidation concentrating on, significantly within the perpetual futures markets.
“For perps (or futures), it’s much more necessary to not let others know/see your orders,” CZ wrote. “If others can see your liquidation level, they may attempt to push the market to liquidate you. Even for those who acquired a billion {dollars}, others can gang up on you.”
The previous crypto government drew a direct parallel to conventional finance (TradFi), the place massive institutional merchants routinely use so-called “darkish swimming pools,” non-public exchanges that disguise order books. He claimed such companies are sometimes “10 occasions greater” than regular order books.
To that finish, Zhao proposed that on-chain platforms may use zero-knowledge (ZK) cryptography or comparable encryption applied sciences to obscure commerce knowledge, together with orders and deposits, till they’re executed. In his opinion, this might create a buying and selling expertise that shields individuals, particularly whales, from MEV assaults and coordinated manipulation.
CZ’s suggestion comes after a collection of dramatic bets by crypto dealer James Wynn, who staked over $1 billion on BTC earlier than being liquidated throughout 4 totally different positions, totaling greater than $100 million. Following the occasion, Wynn tweeted that his expertise had uncovered the corruption within the crypto market, and he suggested merchants to purchase and maintain BTC as a substitute of utilizing it for top leverage.
Rising Options
A number of tasks jumped on CZ’s submit to announce they have been actively working within the privateness area. Sam, from Tristero, revealed that for the final two years, his group has been creating an idea just like what the ex-Binance CEO had outlined.
Others like 0x0 and SKALE are additionally tackling the problem. 0x0 teased its upcoming Spectre platform, which allows privacy-preserving spot and leverage buying and selling, whereas SKALE just lately launched its BITE Protocol, a consensus-layer encryption software designed to eradicate MEV fully by stopping transaction visibility earlier than block finalization. “Somewhat than making use of band-aids, BITE addresses MEV at its root,” stated SKALE CEO Jack O’Holleran.
Nevertheless, not everyone seems to be singing from the identical hymn guide. X Consumer Cedric Beau countered CZ’s proposal, arguing that darkish swimming pools essentially contradict the ethos of crypto:
“Darkish swimming pools in crypto? That’s precisely the stuff we got here right here to keep away from,” said the decentralization fanatic. “The second you disguise the order guide, you recreate insider video games.”
He additional warned that importing TradFi’s “shadowy methods” dangers shedding DeFi’s core worth proposition of openness. “Transparency’s messy, however at the least everybody performs on the identical discipline.”
