البورصات المركزية (CEXs)
البورصات المركزية هي بورصات تقليدية تعمل كوسيط بين المشترين والبائعين. إليك بعض الخصائص الرئيسية:
1. التحكم المركزي: تمتلك وتشغل CEXs من قبل كيان واحد، الذي لديه السيطرة على المنصة وعملياتها.
2. حافظة: تحتفظ CEXs بأموال المستخدمين في محفظتها، مما قد يجعلها عرضة للقرصنة والسرقة.
3. الامتثال التنظيمي: يجب على CEXs الامتثال للمتطلبات التنظيمية، مثل اعرف عميلك (KYC) وقوانين مكافحة غسل الأموال (AML).

The demand for the implementation of Blockchain technology to enhance the security of online transactions and critical business operations has experienced a significant surge. Blockchain has emerged as the most secure application for critical business infrastructure, particularly in sectors such as finance, transportation, and medical industries. However, as the adoption of this technology has increased, it has also brought to light various potential security threats and vulnerabilities. These security threats can be categorized as deliberate and accidental. Deliberate threats are those planned by a dedicated team with specific objectives and target victims, often referred to as attacks. On the other hand, accidental threats, also known as unplanned threats, can be caused by natural disasters or any actions that may result in damage to a system. It is widely acknowledged by experts that Blockchain is susceptible to vulnerabilities stemming from software design flaws, hardware requirements, and protocol-related issues, which can lead to various types of threats within the technology and its applications

The vulnerability of asymmetric cryptography within blockchain technology, specifically the Elliptic Curve Digital Signature Algorithm (ECDSA) for transaction authentication, has been recognized in the context of quantum attacks. ECDSA serves as a widely utilized signature algorithm in Bitcoin, a prominent technology within the blockchain domain. Unlike #centralized networks, blockchain operates as a decentralized network, providing enhanced resistance to tampering. Researchers from the National University of Singapore (NUS) have revealed that Quantum Cryptography minimizes entropy within the system, thereby reducing noise. However, the implementation of quantum cryptography exposes weaknesses in the asymmetric cryptography utilized for digital signatures. In response to this vulnerability, a new signature authentication scheme for blockchain has been suggested, incorporating the lattice-based bonsai tree signature as a protective measure (Hasan et al., 2020). The loss of private keys during a cyber-attack is a common threat in the realm of cybersecurity. To address this, the authors have proposed a private key safety model that involves securely storing the sub-elements of the private key across various operational profiles and incorporating multiple character salts as a shared subsequence within each profile. Additionally, the authors have implemented syntactic, semantic, and cognitive safety controls to establish interdependence among these profiles. Another emerging threat is cryptojacking, also known as drive-by mining, which covertly utilizes individuals' devices to mine #Cryptocurrencies without their consent or awareness. In response to this threat, a detection approach called MineSweeper has been proposed, relying on the cryptographic functions of #Cryptojacking codes through static analysis and real-time monitoring of CPU cache. Furthermore, selfish mining poses a significant threat to the integrity of the Bitcoin network, where a group of miners deliberately withhold a valid solution from the rest of the network to undermine the efforts of honest miners. To mitigate this, a modification to the Bitcoin protocol has been suggested to prevent profitable engagement in selfish mining by mining pools smaller than ¼ of the total mining power. Additionally, vulnerabilities in the peer-to-peer (P2P) layer of cryptocurrency networking have been identified, allowing transactions to be linked to users' IP addresses with over 30% accuracy. To address this, Dandelion++, a lightweight and scalable solution, has been proposed to enhance anonymity using a 4-regular anonymity graph. The presence of Bitcoin nodes exhibiting anomalous behaviour patterns associated with illegal interests has led to the development of a behaviour pattern clustering algorithm to tackle this issue. Furthermore, specific transaction patterns have been employed to cluster nodes owned by the same entity, with the objective of efficiently extracting data from the extensive Bitcoin network.
Routing attacks, which entail partitioning and slowing down the Bitcoin network, present additional challenges. To mitigate these threats, short-term countermeasures such as increasing the diversity of node connections and measuring round-trip time, as well as long-term measures like encrypting Bitcoin communication and utilizing #UDPN connections, have been recommended.

Binance, the world's largest centralized exchange, has announced a collaborative community management structure that will allow Binance users to vote on the listing and delisting of tokens on the platform.

According to the announcement, #Binance will select projects for community voting. . The tokens that receive the most votes will be reviewed by a #centralized exchange company and listed on Binance.
Projects that fail to provide regular progress updates or necessary token information, projects with unscrupulous activities or inactive development teams or communities will be placed in the platform's monitoring zone.
Once a project is placed in the monitoring zone, Binance community members will be able to vote to delist those projects from the platform.
The announcement follows the release of the announcement by Binance. At the time of writing, the number of unique digital assets listed on the site has reached 12.4 million.

With USDe’s supply soaring past $13 billion, its earliest institutional backer is reinforcing its position. YZi Labs’ deepened commitment signals a long-term belief in a crypto-native dollar system, far beyond initial incubation.

SummaryYZi Labs has expanded its stake in Ethena Labs as USDe supply surpasses $13 billion.The move reinforces YZi’s early backing and supports Ethena’s next growth phase.Investment targets deeper USDe integration, BNB Chain expansion, and new product launches.
On September 19, YZi Labs #announced a significant expansion of its stake in Ethena Labs, the protocol engineering the USDe synthetic dollar. The move reinforces the venture firm’s position as a foundational backer, strategically doubling down on a project it first incubated before USDe’s public launch in February of last year.

With USDe supply climbing past $13 billion and total value locked crossing the same mark, YZi Labs’ deeper involvement signals alignment with Ethena’s next growth cycle, including new products like USDtb and the Converge settlement layer.

Fueling Ethena’s next growth phase

While the specific dollar figure of the expanded stake remains undisclosed, YZi Labs outlined a clear strategic deployment for the capital. The investment is targeted to propel three core initiatives: deepening USDe’s integration across both #centralized and decentralized exchanges, accelerating its expansion on BNB Chain, and funding the development of two new flagship products.

These include USDtb, a fiat-backed stablecoin pursuing GENIUS compliance, and Converge, an institutional settlement layer being developed with Securitize and BlackRock’s tokenization partners to bring traditional finance-grade real-world assets on-chain.

Ethena Labs founder and CEO Guy Young framed the renewed partnership as a critical step toward a long-envisioned goal for the digital-asset space.

“We’re thrilled to deepen our partnership with YZi Labs, a long-standing and strategic backer. The holy grail of digital dollar distribution has always been embedding stable, yield-bearing assets directly into the core of the crypto economy. With USDe now scaling across exchanges, DeFi protocols, and global user bases, that vision is becoming a reality,” Young said.
For YZi Labs, the decision reflects its wider mandate. The firm claims to manage more than $10 billion in assets worldwide and holds a portfolio of over 300 ventures across six continents, with more than 65 companies having passed through its incubation programs.

Ethena is among its most prominent bets in digital finance, and it is backed by an equally heavyweight roster of investors that includes Dragonfly, Fidelity, Franklin Templeton, #Binance Labs, Bybit, and OKX.
