The CertiK team found that nearly half of the newly issued Ethereum tokens in the Web3 space are linked to Rug Pull scams. These scams are carried out by organized groups who use liquidity holding addresses for money laundering and risk management. The majority of the funds involved come from centralized exchanges. The article concludes with a warning to users to stay alert and avoid being scammed.

Since DeFi's emergence, the quality and security of on-chain data have been paramount concerns for developers, particularly regarding oracles—the critical bridges between on-chain and off-chain data that are often targeted by attackers. This article explores oracle use cases, common attack patterns, and prevention strategies for oracle manipulation. It provides practical guidance for developers on secure oracle integration while explaining their vital role in the blockchain ecosystem. Through analysis of recent incidents like UwU Lend and Banana Gun, we highlight how data reliability fundamentally shapes DeFi ecosystem stability.

This article is a sponsored deep dive into Zircuit, a Layer 2 solution designed to bring proactive security to blockchain infrastructure. Zircuit's AI-driven security measures promise to detect threats before they can cause harm, offering a glimpse into a safer, more sustainable future for blockchain and DeFi.

Gate Research's report states that in December 2024, the Web3 industry experienced 27 security incidents, resulting in a loss of approximately $4.11 million, a decrease from the previous month. However, contract vulnerabilities remain the primary threat, accounting for 72% of the total losses. Major incidents included the FEG cross-chain vulnerability, Clober DEX liquidity vault attack, Vestra DAO staking contract exploit, Clipper DEX single-asset withdrawal vulnerability, and the HarryPotterObamaSonic10Inu flash loan attack. These events exposed key risks in smart contracts and cross-chain protocols, emphasizing the need for enhanced contract audits, the introduction of real-time monitoring, and multi-layered protection mechanisms to improve platform security and increase user trust.

Privacy 2.0 will enable new economies, new applications—new whitespace to be unlocked. It is arguably the biggest unlock in crypto since smart contracts and oracles. In this article, I’ll break down each privacy-enhancing technology, their impact, and the projects bringing them to life.

A known-plaintext attack (KPA) occurs when a hacker uses pairs of both encrypted and unencrypted data to figure out the encryption algorithm or key. This attack takes advantage of weaknesses in encryption techniques, allowing attackers to identify patterns or relationships between the plaintext and ciphertext. If not properly safeguarded, known-plaintext attacks can undermine the security of an encryption system.

Today, we will analyze the common risks and malicious methods in memecoin from a security perspective, helping general users to master some skills to identify memecoin-related risks and avoid financial losses.

Google's quantum computing chip, "Willow," has demonstrated significant advancements in quantum error correction and computational speed. However, it is currently insufficient to compromise blockchain security mechanisms. While the potential of quantum computing is vast, practical applications capable of threatening existing cryptographic systems remain 15–20 years away. To address the potential risks posed by quantum computing, the blockchain industry must accelerate research and adoption of quantum-resistant cryptography to ensure future security.

Stablecoins play a crucial role in crypto trading, payments, and savings. Over the past year, several notable stablecoin protocols have emerged, offering yields to holders through real-world U.S. Treasury bonds or hedging strategies. This article provides an analysis of these protocols, exploring their operational mechanisms, audit key points, and regulatory challenges.

This article aims to understand the regulatory policies on cryptocurrency in major countries and regions around the world, including an analysis of responses and challenges to significant events. It explores how to address issues like blockchain anonymity, decentralization, and cross-border regulation to ensure compliance and security.

As an important member of the Move Ecosystem, Sui is committed to providing fast and secure transaction services for a variety of blockchain application scenarios. In this article, Beosin will help you understand the security challenges faced by Sui ecosystem users and developers with years of security audit experience.

This article explores the potential of Account Abstraction (AA), particularly its ability to enhance the blockchain user experience through programmable key management systems. The author analyzes the advantages and disadvantages of traditional key management methods (such as 12-word seed phrases) and new technologies like Passkeys, MPC, and cloud TEEs, proposing the integration of AA functionalities to enable key rotation, session keys, and multiple recovery mechanisms.

Crypto has been gaining popularity and becoming more well-known as an efficient way to make payments. However, using crypto for everyday transactions can still be challenging, as many merchants do not accept it as a form of payment. This is where crypto cards come in. These cards, offered by companies such as crypto.com, Wirex, and Gate.io, allow users to convert their crypto holdings into fiat currency that can be used by any merchant that accepts traditional credit or debit cards. With a crypto card, users can easily spend their digital assets in the real world, making crypto payments more accessible and convenient than ever before.

Intellectual property (IP) rights pertain to creative products of the mind. In the rapidly evolving digital age, Web3 IP protection has become a paramount concern for creators and innovators. With the proliferation of digital content and technologies, ensuring the integrity and ownership of creative works has become increasingly challenging.

This article analyzes the significance of the Tornado Cash case from the perspective of a Web3 legal practitioner, looking at the source of OFAC’s regulatory and enforcement power, the definition of Immutable smart contracts, and the future development trend of decentralized networks.
