Security

The article provides an in-depth analysis of the challenges associated with linking identities to public keys in public key cryptography and proposes three solutions: public key directories, identity-based encryption (IBE), and registration-based encryption (RBE). It discusses the application of these solutions in blockchain technology, including their impact on anonymity, interactivity, and efficiency. The article also explores the advantages and limitations of each method, such as IBE's reliance on a strong trust foundation and RBE's optimization of on-chain storage requirements. By comparing these approaches, readers gain a better understanding of the challenges and trade-offs involved in building secure, decentralized systems.

The main argument of this post is that if the desirable end-state is to have programmable privacy infrastructure that can handle shared private state without any single point of failure, then all roads lead to MPC. We also explore the maturity of MPC and its trust assumptions, highlight alternative approaches, compare tradeoffs, and provide an industry overview.

This article argues that privacy in blockchain networks is essential for broader adoption, rather than merely a desirable feature. It highlights the challenges posed by the current transparency of blockchains and emphasizes that varying users and use cases will necessitate different levels of privacy, suggesting that a one-size-fits-all approach is not sufficient.

This article provides a detailed analysis of the security challenges and threats of BTC Layer 2 technology. As the demand for the Bitcoin network grows, Layer 2 solutions such as Lightning Network, Rootstock, Stacks, etc. are developed to improve transaction speed and scalability, but at the same time bring new security issues, such as channel attacks, smart contract vulnerabilities, double Flower attack etc.

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.
