This article, provided by Web3 Lawyer, offers a comprehensive guide on how Chinese companies can compliantly invest in overseas crypto assets to tap into the growth of the Web3 sector. It outlines the benefits of investing in crypto assets, the conditions required for compliant investment, and the ODI (Outward Direct Investment) registration process. This guide aims to help businesses diversify their investments, hedge risks, and boost their international competitiveness in the global market.

This article delves into the essential role of quantum-resistant tokens in protecting digital assets from potential threats posed by quantum computing. By employing advanced anti-quantum encryption technologies, such as lattice-based cryptography and hash-based signatures, the article highlights how these tokens are pivotal in enhancing blockchain security standards and safeguarding cryptographic algorithms against future quantum attacks. It addresses the importance of these technologies in maintaining network integrity and advancing blockchain security measures.

A detailed 2024 Web3 blockchain security analysis, covering major incidents like BitForex’s hack, Rug Pull events, funds laundering trends, and the state of project audits. It examines the growing security challenges, including the impact of cross-chain money laundering, and offers insights on how to protect digital assets in the rapidly evolving ecosystem.

Blockchain is a high-stakes industry. Successful Web3 projects can quickly build billions in value when holding and transacting users’ funds. Security audits are the building blocks of a fortress against malicious attacks and devastating code failures.

Understanding these tactics is your first defense. Whether it’s enabling multi-factor authentication (MFA), verifying URLs or scrutinizing investment opportunities, taking proactive steps can safeguard your assets. This guide explores the strategies scammers use, red flags to watch out for and actionable tips to keep your digital investments safe from fraud.

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.
