Security

As the demand for privacy protection grows, TEE technology has once again become a focal point. TEE provides a secure execution environment independent of the main system, protecting sensitive data and code. Multiple blockchain projects, such as Flashbots, Taiko, and Scroll, are exploring TEE applications to achieve private transactions, decentralized block building, and multi-proof systems. While TEE offers advantages in security and privacy, it still faces centralization risks. In the future, it may need to be compatible with more hardware vendors and set node ratios to reduce reliance on a single supplier, thereby further enhancing decentralization.

In this issue, we use the TRON wallet as an example to explain the concept of multi-signature phishing, including the multi-signature mechanism, common hacker operations, and how to prevent your wallet from being maliciously multi-signed.

This article offers a comprehensive guide on how to conduct a security checkup on your account, covering how to review authorized apps, check delegation settings, and monitor login activity and devices. It also recommends activating two-factor authentication (2FA) and setting up extra password protections to strengthen your account's security.

TON (The Open Network) is a rapidly evolving blockchain project that has attracted significant attention due to its advanced technology and rapidly growing user base. However, participating in such a phenomenon requires a thorough analysis, assessment, and interpretation of its risks. This report aims to provide in-depth risk analysis and compliance interpretation for users and potential participants in the TON ecosystem.

The core structure of the Babylon Protocol is the Babylon blockchain, which is a POS blockchain built on the Cosmos SDK and compatible with Cosmos IBC. It enables data aggregation and communication between the Bitcoin chain and other Cosmos application chains. Users can lock Bitcoin on the Bitcoin network to provide security for other POS consumption chains while earning staking rewards. Babylon allows Bitcoin to leverage its unique security and decentralization features to provide economic security for other POS chains.

This article describes a case of a user losing assets due to a phishing scam on Solana. It explains the differences between Solana and EVM chains and their unique fraudulent tactics, such as token account ownership transfer, no need for pre-authorization, allowing multiple token transfers in a single transaction, and using Durable Nonce for fraud.

Movement aims to integrate the Move language into the EVM ecosystem to address long-standing security issues without relying on L2 solutions. MOVE reduces blockchain transaction storage space and computation costs through an optimization technique called "modular packing," which bundles multiple smart contracts into a single module to lower storage and indexing costs, and increases execution speed by reducing the steps needed to execute bytecode.

In criminal cases, if there is a significant fluctuation in cryptocurrency prices within a short period, how should the amount involved in the crime be determined? Different standards of determination could directly influence the future direction of the case.

This article discusses BTC market dynamics and the challenges of the "buy the dip" strategy, and addresses readers' concerns about Bitcoin Core client no longer supporting private key import. It concludes that Bitcoin Core still supports private key import, just requiring new methods.

TeleportDAO and Eigen Labs recently co-authored a paper addressing the security and efficiency issues light nodes face in accessing and verifying on-chain data within Proof of Stake (PoS) blockchains. The paper introduces a novel solution that enhances the security and efficiency of light nodes in PoS blockchains through various measures such as economic incentives, insured pre-security mechanisms, customizable "programmable security," and cost-effectiveness.

Recently, scams in the cryptocurrency space have become rampant, leading to losses of 4.6 billion dollars in 2023 and 500 million dollars already lost in early 2024. Common problems include vulnerabilities in DeFi protocols (like flash loan attacks and oracle manipulation), phishing websites, and fake airdrops. To protect yourself, enhance your security awareness, regularly check and revoke unknown authorizations, use cold wallets for most of your assets, and avoid clicking on unknown links or downloading unfamiliar plugins.
