At the Hong Kong Web3 Carnival, Vitalik provided a comprehensive overview of Ethereum’s new phase direction: establishing Ethereum as a public bulletin board and shared computation layer, with strategic emphasis on scaling, zkVM verification, account abstraction, privacy enhancements, and quantum-resistant security. This article dissects the roadmap across technology, governance, and application layers, examining its medium- and long-term implications for developers, investors, and the broader industry narrative.

Restaking is one of the core mechanisms in the EigenLayer protocol. It allows ETH that has already been staked on Ethereum to be reused for validation tasks in other blockchain applications, creating a structure in which the same pool of security can be used multiple times. This changes the traditional limitation where staked assets can only secure a single chain, allowing Ethereum’s economic security to extend across a broader modular ecosystem.

EIGEN (EigenLayer) is a core asset and mechanism component tied to Ethereum’s restaking protocol. It is used to extend the blockchain shared security model, allowing staked assets that originally served only the Ethereum mainnet to be reassigned and used across multiple external validation networks. Through this mechanism, EigenLayer turns Ethereum’s security capacity into reusable infrastructure, supporting a broader range of decentralized applications.

NEAR, Solana, and Ethereum are among the most representative Layer 1 blockchains in the industry today. All three support smart contracts and decentralized applications, yet they follow clearly different technical architectures and scaling paths. As Web3 applications continue to expand, network performance, scalability, and developer experience have become key factors shaping ecosystem growth.

NEAR Protocol (NEAR) is a Layer 1 blockchain network built on sharding technology. It is designed to support large scale decentralized applications by improving scalability and user experience. As blockchain technology has evolved from simple asset transfers to complex application ecosystems, traditional public blockchains have gradually revealed limitations in performance, fees, and user experience. NEAR Protocol was created as infrastructure for the next generation of Web3 applications.

NEAR Protocol (NEAR) is a Layer 1 blockchain network built using sharding, with the goal of enabling large-scale decentralized applications through improved scalability and usability. As blockchain technology evolves from simple asset transfers to complex application ecosystems, traditional public chains have begun to show limitations in performance, cost, and user experience. NEAR was designed as infrastructure for the next generation of Web3 applications in response to these challenges.

This week’s recap highlights continued macro-driven volatility as Bitcoin and Ethereum remained under pressure amid fragile sentiment and mixed flows. Meanwhile, regulatory developments, institutional positioning, and ongoing infrastructure progress underscored steady momentum across the evolving Web3 ecosystem.

Figma's stock price saw a temporary drop in April 2026, sparking focused debates within the marketplace regarding the disruptive effects of Claude Design and AI-powered design platforms. This article examines the medium- and long-term impacts of AI on the design industry, as well as practical strategies for response, through five key lenses: valuation logic, workflow restructuring, job specialization, tool competition, and organizational governance.

Substrate is a modular blockchain development framework developed by Parity Technologies. It allows developers to quickly build customized blockchains and connect them seamlessly to the Polkadot (DOT) network as parachains. Compared with the traditional smart contract development model, Substrate offers greater flexibility, stronger scalability, and chain level customization at the protocol layer. That is why it has become the core development framework of the Polkadot ecosystem and a key foundation that enables its multi-chain architecture to scale efficiently.

Polkadot Parachains are independent blockchains connected to the Relay Chain, capable of processing transactions in parallel under a shared security model while enabling cross-chain communication across the Polkadot network. Compared to traditional single-chain blockchains, Parachains offer greater scalability, lower security setup costs, and stronger interoperability. They are a core component of Polkadot’s multi-chain architecture and a key foundation for achieving cross-chain scalability.

Polkadot (DOT) is a Layer0 blockchain network centered on cross chain interoperability. Through its Relay Chain and Parachain architecture, it enables data and assets to move across different blockchains. The DOT token is mainly used for network staking, governance voting, and parachain slot auctions. Compared with the traditional single chain model, Polkadot offers stronger scalability and a shared security framework, though it also faces challenges such as ecosystem competition and development complexity.

In April 2026, the KelpDAO Bridge was attacked, with the attacker using abnormally minted rsETH as collateral on Aave to borrow a significant amount of WETH. This led to roughly $200 million in bad debt discussions and liquidity stress. This article provides an objective review of the event sequence and structural takeaways from the perspectives of mechanism, marketplace response, and governance framework.

Through the MCP protocol, multi-chain data aggregation, and a Data Liquidity mechanism, SkyAI provides AI Agents with efficient on-chain data services. This article takes an in depth look at SkyAI’s technical architecture and its central role in AI + Web3 data infrastructure.

SkyAI and Chainbase are both AI-driven Web3 data infrastructure protocols, but their core positioning differs. Chainbase focuses on building a multi-chain data indexing and standardized data service layer, while SkyAI goes further by introducing the MCP protocol and a Data Liquidity mechanism, aiming to provide AI Agents with callable and liquid on-chain data resources. In simple terms, Chainbase solves the problem of “data accessibility,” whereas SkyAI focuses on “data interactivity and circulation.” As AI Agents and automated Web3 applications continue to evolve, the two represent distinct development paths within the AI data infrastructure landscape.

From ChatGPT to Physical AI, artificial intelligence is evolving from cognitive systems to real-world execution systems. This article breaks down the a16z framework, exploring how robotics, auto experimentation, and data flywheels are reshaping the AI value chain for its next stage.
