The primary difference between Cardano and Ethereum lies in their ledger models and development philosophies. Cardano adopts the Extended UTXO (EUTXO) model derived from Bitcoin and emphasizes formal verification and academic rigor. Ethereum, by contrast, uses an account-based model and, as a pioneer of smart contracts, prioritizes rapid ecosystem iteration and broad compatibility.

Security researchers have identified that hackers are exploiting "search poisoning" to manipulate Bing AI search results, steering users toward downloading a fake OpenClaw application embedded with infostealer malware, leading to the theft of crypto assets and sensitive information. This article examines the attack methodology, technical specifics, and the broader implications for the industry.

A user on CoW Swap exchanged roughly $50.43 million in aEthUSDT for AAVE. Because slippage exceeded 99%, the user ended up with only about $36,000 in assets, sparking widespread market concern. This article examines Aave's collateral swap mechanism, transaction routing challenges, and associated DeFi risks.

Resolv's USR stablecoin experienced a significant security breach, allowing an attacker to mint 80 million uncollateralized tokens and liquidate roughly $25 million, which caused a substantial price depeg. This article offers an in-depth examination of the incident, the attack method, and the inherent risks of DeFi stablecoins.

A wrench attack is the physical targeting of cryptocurrency holders to unlawfully obtain possession and ownership of their assets through physical force or threat of harm.

This article will use Optimism's fraud proof solution as a reference to analyze its approach based on the MIPS virtual machine and interactive fraud proofs, as well as the main idea behind ZK-based fraud proofs.

Gate Research report indicates: In February 2025, the Web3 industry experienced 15 security incidents with total losses of $1.676 billion—a significant increase from the previous month. These incidents primarily involved contract vulnerabilities and account hacks, accounting for 53.3% of total losses in the crypto industry. Most losses occurred on the BSC blockchain. Major incidents included the Bybit exchange wallet theft, Infini's lack of strict permission controls, and ionic falling victim to a social engineering attack.

The cryptocurrency industry is experiencing an unprecedented security crisis, marked by frequent and devastating hacker attacks that have eroded trust in the industry. This article examines recent high-profile hacking incidents, such as the $1.46 billion theft from Bybit, along with historical cases, to uncover the various factors driving these attacks, including technical flaws, human vulnerabilities, economic incentives, and regulatory gaps.

This article explores the impact of the recent hack on Aave, Ethena, and USDe, analyzes how DeFi systems responded to the event, and examines whether Proof of Reserves could prevent over $20 million in liquidations.

This article explores OP_VAULT, a Bitcoin feature designed to enhance security by safeguarding funds from loss or unauthorized access. As Bitcoin adoption grows, OP_VAULT introduces "covenants," which let users establish predetermined guidelines for how their cryptocurrency can be used. This feature adds both security and flexibility for protecting digital assets.

In this decentralized digital world, everyone is responsible for safeguarding their own assets and acting as the first line of defense against risks. We can’t rely on others, but we can rely on rules and common sense. Always remember: Never share your mnemonic phrase.

We can't just shift to a world where only web3 exists without sharing anything. No, we still need to share, but only what's necessary.
