FHE (Fully Homomorphic Encryption) allows third parties to perform unlimited calculations and operations on encrypted data without decryption, thus achieving combinable on-chain privacy calculations. ArkStream Capital has written an article introducing the concept, application scenarios, and ecosystem of FHE, as well as the FHE-Rollup type Layer2 solution that Fhenix is building.

This article, written by Vitalik Buterin, explores the similarities and challenges of Ethereum Layer 2 (L2) and execution sharding in blockchain scaling. The article explains that the L2 ecosystem is actually sharding on a technical level, and discusses the diversity of execution environments, security trade-offs, transaction speed, and the organizational and cultural benefits of L2. At the same time, Vitalik highlighted the coordination challenges faced by the L2 ecosystem and raised the importance of cross-L2 infrastructure.

Optimism is a Layer 2 solution based on Ethereum that provides fast, stable, scalable and low-cost blockchain services. By running on Layer 1 of the Ethereum main chain, it helps alleviate network congestion, thereby reducing Transaction costs and processing time. Hyperchain is a multi-chain network structure based on Layer 2 technology that solves the horizontal scalability challenges of traditional blockchains. By treating each chain as an interchangeable computing resource, the commercialization of blockchains allows Developers to build cross-chain applications without increasing systemic risks, sharing not only security and communication layers but also an open-source technology stack. This design allows developers to focus more on building applications on the entire super chain, without having to worry about the specific technical details of individual chains.

This article provides a comprehensive analysis and in-depth technical discussion. It not only explains how constraint mechanisms work but also explores the innovative applications they might bring and their long-term impact on the Bitcoin network and the broader blockchain ecosystem. Additionally, the article discusses the challenges faced in implementing these technologies and the considerations of the community, offering readers a holistic view to understand the ongoing technical innovations and discussions within the Bitcoin network.

Zero-knowledge proofs have the potential to create a more private and scalable blockchain ecosystem. However, many aspects of zero-knowledge are misunderstood or differ from commonly perceived implementations. This article analyzes ZKPs from two main perspectives: zero-knowledge and succinctness. When ZKPs and ZK rollups eventually mature technologically, they will certainly offer better solutions to address the blockchain trilemma.

This article introduces optimization ideas for BTC withdrawal bridges and the OP-DLC bridge proposed by Bitlayer to address the deficiencies of BitVM bridges. This technology allows for lightweight smart contract functionality on the Bitcoin chain, reducing reliance on central authorities and increasing the decentralization and trustlessness of transactions.

The transformation into a social re-staking modular L2 is not only a technological leap for Cyber but also a profound exploration and forward-looking layout for the future of social networks. The article explains how Cyber operates and its features, providing a truly decentralized environment. This allows users to expand their influence more fairly and directly, and build closer connections with their fans.

RGB is a technology that is not limited to crypto. It can be widely used in our non-crypto scenarios. As the protocol becomes more mature, we will see more and more use cases.

GitHub, as a development platform for open-source projects, provides rich data resources that can help investors understand the health of cryptocurrency projects and the level of developer engagement. The article emphasizes three key aspects of GitHub activity: transparency and open development, developer participation and community strength, and its function as an early warning system. By analyzing quantitative indicators such as commit frequency, issue resolution, branches, and stars, investors can assess project activity, community engagement, and project popularity. The article suggests that investors incorporate GitHub data into their risk management, project comparison, and strategic investment decisions. Using Ethereum as a case study, it demonstrates the high activity and number of contributors in its GitHub repository, reflecting the vitality of its ecosystem.

Turbos recently launched two innovative liquidity strategies in the Sui DEX, hoping to provide new opportunities for market participants. These include the innovative SUI-USDC automated rebalance vault and SUI-USDC DCA strategy based on the CLMM DEX, operating in a decentralized manner to provide users with real-time and accurate token pricing. Turbos also introduced an innovative intelligent routing mechanism designed for the Sui-Move language, a first for the Sui DEX ecosystem, enabling more efficient swap levels.

The EthStorage team proposed the web3:// access protocol and the EthStorage second-layer storage protocol, aiming to help decentralized applications (DAPP) achieve true trustlessness. Most of the current DAPP front-ends and databases are not deployed on Ethereum and cannot fully inherit the security of Ethereum. The web3:// protocol allows front-end code to be deployed and accessed through smart contracts, while the EthStorage protocol reduces on-chain data storage costs through PoRA and zero-knowledge proofs. These two technologies enable DAPP to get closer to Ethereum’s decentralized vision and achieve permanent operation and censorship resistance.

This article compares the smart contract programming models of Solana and Ethereum. Solana's on-chain programs are similar to Ethereum's smart contracts, but Solana offers a different runtime environment through its unique account model and data decoupling approach. Solana's account model separates code and data storage, enhancing security. Solana primarily uses the Rust language for smart contract development, which offers high performance and security but has a steep learning curve. Ethereum, on the other hand, mainly uses Solidity, providing a simpler and more mature development experience. Despite the development challenges with Solana, its high throughput, low costs, and scalability make it an ideal choice for developing high-performance dApps.

Modular blockchain is not just a technological shift but also a crucial strategy to drive the entire blockchain ecosystem toward future challenges. We will dissect the concept of modular blockchain, analyze related projects, and provide a comprehensive, practical interpretation of modular blockchain knowledge to help readers better understand. At the same time, we will also look ahead to future development trends. If the ecosystem can be more harmonious and interconnected, users will be able to use blockchain technology more easily, which will also attract more new users to Web3.

Decentralized cloud services have always been one of the most important applications of blockchain. Web3 + cloud services are not only a very good narrative direction, but also very easy to combine with AI to further enhance the imagination. DFINITY IC has great technical challenges in achieving real-time consensus calculations in a purely asynchronous environment such as cloud services. Arweave AO breaks the shackles of the blockchain and does not deal with the calculation itself and the achievement of consensus. Instead, it employs an economic model and lazy verification to guarantee the accuracy of computation results, offering a novel approach to decentralized computing.

This article explains the concept of the Hooks programming model, which allows developers to insert custom code into the execution path of the system, application or library through predefined functions or code blocks, improving the scalability and customizability of the program. Uniswap V4 introduces Hooks, through which functions such as dynamic fees, on-chain price limit orders, and time-weighted average market makers can be implemented, enhancing the functions of DApp and the network effect of Uniswap.
