Security

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.

Cardano is a public blockchain network centered on smart contracts, utilizing a layered architecture and a Proof of Stake (PoS) mechanism. It aims to provide a more secure and scalable underlying support for decentralized applications and financial infrastructure. Its consensus mechanism, Ouroboros, enhances network security and energy efficiency through mathematical modeling and formal verification design. ADA, Cardano's native token, serves as both the settlement currency for network transactions and a key tool for staking and governance. Through decentralized stake pools and incentive mechanisms, network participants collectively maintain system operations and security, enabling Cardano to operate continuously without centralized control.

GT (GateToken) and BNB represent two core logics in the evolution of platform tokens: the former emphasizes "on-chain asset security and underlying infrastructure," while the latter is dedicated to "high-performance transactions and full-stack ecological expansion."

GateToken (GT) is the native asset and core value carrier of the Gate ecosystem. It not only supports the rights and interests system of the centralized exchange but also serves as the Gas payment token for GateChain. Acting as a strategic bridge connecting CeFi and DeFi, GT secures the network through a Proof-of-Stake (PoS) consensus mechanism and provides users with multiple utility credentials, including cross-chain resource scheduling, ecological governance voting, and priority participation in the Launchpad.

Web3 and Web4 represent a logical progression in the evolution of the internet, transitioning from a "transformation of production relations" to a "leap in productivity." Web3, anchored by blockchain and cryptography, focuses on solving issues of "Ownership" and decentralized trust, returning power from centralized platforms to individuals. In contrast, Web4 is defined as the "Symbiotic Web," with its core revolving around "Agentic Power."

This includes the breakdown of Terra’s algorithmic stablecoin mechanism, the resulting liquidity crunch, controversies surrounding institutions like Jane Street, and updates on related legal proceedings.

Nonce stands for "Number used once," and is a cornerstone of modern cryptography and blockchain technology. Whether securing online payments via SSL/TLS protocols or enabling Bitcoin's Proof-of-Work mining mechanism, the nonce is vital for maintaining communication uniqueness and preventing malicious replay attacks. This guide offers an in-depth exploration of how nonces function and why they are indispensable to digital security.

The theft of 127,000 BTC from the LUBIAN mining pool has once again impacted the industry. This report provides a comprehensive technical analysis of the incident, highlighting links among PRNG vulnerabilities, private key generation flaws, and nation-state attack characteristics. By reconstructing the attack timeline and examining on-chain evidence, the report details the circumstances surrounding the U.S. Department of Justice’s Bitcoin confiscation. It also offers an in-depth analysis of Bitcoin security mechanisms and mining pool defense, presenting important security insights for the crypto industry.

In-depth analysis of polygon labs' miden virtual machine architecture: explore how it applies STARK zero-knowledge proof technology to deliver a high-performance, scalable, and privacy-centric ZK-Rollup solution, helping advance Web3 infrastructure to the next stage.

A $120 million exploit affected Balancer V2. The vulnerability impacted multiple chains, including Ethereum, Arbitrum, and Berachain, and resulted in cascading consequences. Due to its shared architecture, Berachain initiated an emergency full-chain shutdown and now plans to implement a hard fork. This event underscores the systemic risks DeFi protocols face regarding precise computation and maintenance of protocol invariants. In addition to systemic risks, it also highlights the governance dilemmas decentralized projects face when responding to crises: This event raises critical questions about balancing security and decentralization.

The article illustrates, through multiple real-world cases, how hackers exploit vulnerabilities in IoT devices to launch attacks — including intrusions into coffee machines, casino fish tanks, and access sensors.

Aqua, a project built on Solana, is reportedly involved in a major "rug pull," with approximately 21,700 SOL (valued at around $4.65 million) at stake. Although Aqua presented product offerings, audit reports, and collaborations with multiple partners, the raised funds have been split and transferred off the platform. This incident exposes the inherent risks concealed behind the project's seemingly "legitimate" appearance.

The article analyzes the tactics used by hackers and the vulnerabilities of cryptocurrency exchanges. It also shows how Bybit strengthens its security by combining the self-custody advantages of DeFi and enterprise-grade security protocols.
