Les r\u00e9cents \u00e9v\u00e8nements \u00e0 propos du c\u00e9l\u00e8bre trader James Wynn ont soulev\u00e9 de nombreux probl\u00e8mes dans l\u2019\u00e9cosyst\u00e8me crypto. Aujourd\u2019hui, Changpeng Zhao (CZ), le fondateur de Binance, a \u00e9mis une id\u00e9e r\u00e9volutionnaire \u00e0 travers un post sur X. Il a en effet invit\u00e9 les d\u00e9veloppeurs \u00e0 se pencher sur la cr\u00e9ation d\u2019un DEX (Decentralized Exchange) Dark Pool<\/strong>. Analysons ensemble de quoi il s\u2019agit, quelles sont les probl\u00e9matiques r\u00e9solues ainsi que le point de vue de CZ.<\/span><\/p>\n

Le probl\u00e8me des attaques MEV<\/span><\/h2>\n

\"\"<\/p>\n

La blockchain a pour avantage de laisser tout transpara\u00eetre. Chaque transaction est visible par tous les validateurs et c\u2019est ce qui fait d\u2019ailleurs la s\u00e9curit\u00e9 du r\u00e9seau. Malheureusement, certains profitent de cette visibilit\u00e9 pour faire du profit, c\u2019est ce qu\u2019on appelle une attaque MEV (Maximal Extractable Value)<\/strong>.<\/span><\/p>\n

En effet, les mineurs profitent de leur accessibilit\u00e9 aux transactions pour rep\u00e9rer celles qui sont int\u00e9ressantes et faire du profit dessus. Ces transactions sont la plupart du temps des transactions aux montants importants<\/strong> qui font bouger significativement le prix de la crypto<\/a> concern\u00e9e.<\/span><\/p>\n

Apr\u00e8s avoir rep\u00e9r\u00e9 ces transactions, les mineurs ont trois possibilit\u00e9s. Si c\u2019est un achat<\/strong>, ils peuvent se positionner avant la transaction pour profiter de l\u2019augmentation du prix. C\u2019est ce qu\u2019on appelle un front-running<\/strong>. Si c\u2019est une vente, ils peuvent se positionner apr\u00e8s pour profiter de la baisse du prix<\/strong>. C\u2019est ce qu\u2019on appelle du back-running<\/strong>.<\/span><\/p>\n

Dans la majorit\u00e9 des cas, les deux sont ex\u00e9cut\u00e9s et c\u2019est ce qu\u2019on appelle un sandwich. \u00c0 titre d\u2019exemple, le MEV extrait de 2024 est d\u20191,1 milliard de dollars<\/strong>. Pour 2025, il est estim\u00e9 \u00e0 plus d\u20191,5 milliard si aucune mesure n\u2019est prise jusqu\u2019\u00e0 la fin de l\u2019ann\u00e9e. En sachant que 80 % des transactions<\/strong> sur Ethereum<\/a> utilisent d\u00e9j\u00e0 des n\u0153uds priv\u00e9s, un changement radical doit \u00eatre fait au niveau du fonctionnement des DEXs.<\/span><\/p>\n

La proposition de CZ : Un DEX Dark Pool pour la DeFi<\/span><\/h2>\n

\"\"<\/p>\n

Aujourd\u2019hui, \u00e0 travers un post<\/a> sur X, CZ a \u00e9mis l\u2019id\u00e9e d\u2019une solution qui pourrait bien r\u00e9gler ce probl\u00e8me. En effet, avec le principe d\u2019un DEX Dark Pool, la confidentialit\u00e9 est similaire \u00e0 celle des dark pools. C\u2019est-\u00e0-dire que les ordres, les d\u00e9p\u00f4ts ainsi que les positions sont cach\u00e9es jusqu\u2019\u00e0 ex\u00e9cution compl\u00e8te<\/strong>.<\/span><\/p>\n

Pour faire cela, le fondateur de Binance<\/a> sugg\u00e8re m\u00eame quelques pistes. Il pense qu\u2019il serait possible de masquer les d\u00e9p\u00f4ts sur les smart contracts en utilisant la technologie ZKP<\/strong>. Le zero-knowledge proofs est un protocole de validation qui garantit la confidentialit\u00e9 des utilisateurs. Les rollups ZK permettent en effet de v\u00e9rifier les transactions sans consulter directement les donn\u00e9es r\u00e9elles<\/strong>.\u00a0<\/span><\/p>\n

B\u00e9n\u00e9fices potentiels et impact sur la DeFi<\/span><\/h2>\n

Avec plus d\u20191 million d\u2019impressions<\/strong> et 2 000 commentaires en moins de 24 heures, le post de CZ sur X n\u2019est pas pass\u00e9 inaper\u00e7u. Une viralit\u00e9 coh\u00e9rente quand on sait qu\u2019il a encourag\u00e9 les d\u00e9veloppeurs \u00e0 se pencher s\u00e9rieusement sur le sujet.<\/span><\/p>\n

Juste une id\u00e9e de dimanche. Si vous travaillez sur un tel projet, n\u2019h\u00e9sitez pas \u00e0 me contacter<\/strong> sur <\/span>https:\/\/reachme.io\/@cz_binance<\/span><\/a>. Je ne garantis ni que j\u2019investirai, ni m\u00eame que je r\u00e9pondrai.<\/span><\/p><\/blockquote>\n

En \u00e9voquant la possibilit\u00e9 d\u2019investir lui-m\u00eame<\/strong> dans un projet de DEX dark pool, le fondateur montre qu\u2019il croit fermement \u00e0 son importance dans la DeFi actuelle. Avec une TVL \u00e0 plus de 85 milliards de dollars<\/strong>, la finance d\u00e9centralis\u00e9e est en plein essor et la lutte contre le MEV aussi. Suite \u00e0 l\u2019annonce de CZ il ne faudrait certainement que quelques semaines avant de voir appara\u00eetre les pr\u00e9mices d\u2019un DEX dark pool.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
