Protocol Guild, as a solid backbone for Ethereum L1 development and maintenance, plays a crucial role in the ecosystem. It is dedicated to providing financial support to core contributors within the Ethereum ecosystem through native token incentives. This ensures the vibrant development and continuous innovation of the Ethereum network. With its unique donation and funding allocation mechanisms, it serves as a bridge connecting funds with contributors.

This article summarizes and distills the basic framework of the DePIN project, providing an overview using the "WHAT-WHY-HOW" structure to review and summarize the DePIN track. The author then outlines an analytical approach to understanding the DePIN project based on their experience, focusing on detailed analysis of specific "computing power" projects.

Arweave is a decentralized data storage protocol that enables permanent storage and global access through its Blockweave and SPoRA consensus, addressing the scalability, data availability, and cost issues present in blockchain data storage.

This article explores the significance and current state of blockchain airdrop mechanisms, focusing on the innovative measures taken by LayerZero and ZKSync to address Sybil attacks and other challenges. Through self-reporting and bounty systems, LayerZero successfully flagged and filtered a large number of potential Sybil addresses, while ZKSync ensured fairness in distribution through strict qualification criteria and behavior pattern recognition. These cases provide valuable insights for the future design of airdrop mechanisms.

Symbiotic and Eigenlayer are two emerging protocols in the restaking field, but their design philosophies are vastly different. Symbiotic emphasizes permissionless and modular features, supports multi-asset and customizable parameters, and uses immutable core contracts, reducing governance risks. Eigenlayer, on the other hand, focuses on ETH and its derivatives, adopts a more centralized management approach, simplifying operations but presenting bundled risks. The launch of Symbiotic and its collaboration with the Mellow protocol offer more options and airdrop opportunities for the DeFi community. The competition and cooperation between the two will further drive the development of the restaking market.

Under decentralization, the layout and utilization of infrastructure in DePIN can achieve higher efficiency and lower costs while enhancing the overall system's security and resilience. Unlike traditional centralized equipment providers, the updating and maintenance of DePIN equipment are jointly undertaken by project teams and miners. Equipment providers are only responsible for the research, development, and sale of the equipment, while the updating and maintenance are completed by the supply-side users. For DePIN projects, realizing data interoperability between multiple chains can maximize the value of data. This not only represents a potential breakout point for the DePIN track but also directly benefits cross-chain protocols amid this growth wave.

This article introduces the technology and applications of chain abstraction, emphasizing the inevitability of a multi-chain future and exploring how chain abstraction can enhance user experience.

Canceling a transaction can be difficult because it typically requires specialized knowledge and an understanding of the steps involved in resolving the issue. This article provides examples and execution steps for Web3 users to cancel a transaction before it is confirmed on the blockchain.

This high-level guide outlines the common design variations of on-chain options and how they use oracles in their pricing and settlement.

This article analyzes the mechanism design and economic model of MOPN, an NFT placement mining game, detailing the design and implementation of full-chain games using MOPN as an example.

Every blockchain has its own independent ecosystem, but through "cross-chain bridges," different blockchains can connect, enabling the transfer of assets and information. This article will provide a comprehensive analysis of the functions, types, transaction methods, popular projects, and potential risks associated with cross-chain bridges.

Symbiotic is a shared security protocol that acts as a coordination layer, enabling network builders to control and adjust their (re)staking strategies in a permissionless manner. Considering the current re-staking protocol EigenLayer supports only ETH and some ETH derivative staking, while Symbiotic supports staking of any asset following the ERC-20 token standard, the two may become direct competitors.

As a new form of productive relationship, Web3 naturally fits with AI, which represents a new type of productivity. This simultaneous progress in technology and productive relationships is at the core of io.net's logic. By adopting the "Web3 + token economy" economic infrastructure, io.net aims to transform the traditional production relationships between cloud service giants, mid-to-long tail computing power users, and idle global network computing resources.

USDX is an emerging synthetic dollar stablecoin protocol that adopts a multi-chain, multi-currency strategy, resulting in higher overall returns compared to various re-staking, LSD, and other yield methods or products. USDX has chosen a path where users can earn returns by holding stablecoins, with a risk curve distinct from existing market products, thereby avoiding the relatively crowded mainstream cryptocurrency yield strategies. It does not rely on traditional banking infrastructure and features censorship resistance, scalability, and high stability. Compared to current existing projects based on mainstream yet singular USD stablecoins like BTC, USDX aligns more closely with the concept of new crypto savings. It offers a savings tool based on multiple currencies that is available globally.

Bitcoin's proof-of-work mechanism limits holders from earning yields directly through staking, despite Bitcoin's dominant position in market value. A significant amount of Bitcoin remains underutilized. Through the Master Protocol, users can stake Bitcoin on various Layer 2 solutions and receive LST as their staking certificate. This allows users to reinvest their LST in multiple scenarios without compromising liquidity, ensuring returns. By adopting the re-staking protocol, users can further stake LST to earn LRT, enhancing their investment capabilities and asset liquidity.
