This article provides an in-depth look at the latest developments in OP Mainnet, focusing on the new fault-proof mechanism and its effects on the accuracy and efficiency of decentralized transactions. It also explores OP Stack as the technical framework for Ethereum's Layer 2 network and discusses how OP Labs incorporates zero-knowledge proof technology into OP Stack via OP Succinct to enhance Ethereum's scalability.

In this article, we survey the trustless interoperability landscape by defining and discussing six levels of interoperability solutions between fragmented rollup ecosystems.

Learn about the latest developments from the first two days of the Fractal mainnet launch, including $FB token circulation, mining rewards, and the inscription market.

Learn how Fractal Bitcoin improves Bitcoin transaction speed and participate in early projects through PoW, NFT and other methods to seize airdrop rewards. <!-- Copy and paste the converted output. --> <!----- You have some errors, warnings, or alerts.

Compared to centralized exchanges, many decentralized exchanges (DEXs) have complex user interfaces and cumbersome operation processes. For users without a technical background, using a DEX may present a higher barrier. Existing limitations include performance bottlenecks, cost and scalability issues, fragmented liquidity, and suboptimal user experience. From a technical perspective, the Vessel protocol can be seen as a state machine consisting of user states (accounts, orders, balances, etc.) and system states (timestamps, price oracles, etc.). Through the cooperation of three components—sorter, prover, and smart contracts—these tasks are carried out sequentially. The ZK system also supports cross-chain operations, making asset transfers and transactions between different blockchain networks more secure and efficient.

Explore how zero-knowledge proofs (ZK) can be integrated into Bitcoin, focusing on two approaches for SNARK verification: enabling OP_CAT in Bitcoin scripts and leveraging BitVM. While OP_CAT would allow direct SNARK support within Bitcoin scripts, BitVM introduces fraud proofs and Chain State Proofs to lower verification costs.

The ZK industry is evolving from a focus on infrastructure to a focus on ZKApps. Advances in cryptographic proof systems and decentralized proof infrastructure have made ZKApps faster and more cost-effective, bringing zero-knowledge technology closer to mainstream adoption. This article offers readers a comprehensive overview of ZKP and ZKApps, and explains why industry experts view ZK as a promising solution to the blockchain trilemma—balancing security, scalability, and decentralization without compromising security.

This article introduces the ZK proof system workflow and explores the challenges and optimization strategies for accelerating MSM and NTT computations.

This article compares two blockchain scaling solutions: Ethereum's ZK Rollups and Solana's ZK Compression. It explores their advantages and challenges in terms of technical implementation and application.

BlobScriptions, introduced by Ethereum, use blob technology to make data storage and transmission cheaper and more efficient. Like Bitcoin's inscriptions, BlobScriptions let users embed different types of data directly onto the Ethereum blockchain. When this blob feature was launched, it temporarily increased Ethereum gas fees. In this article, we will explain what BlobScriptions are and how they work in a straightforward way.

The ZK coprocessor can be regarded as an off-chain computing plug-in derived from the modular concept. Its function is similar to the GPU in our traditional computers that shares graphics computing tasks for the CPU, that is, a processor that shares computing tasks in specific scenarios. . Under this design architecture, heavy data and complex calculation logic tasks that public chains are not good at can be calculated through the ZK coprocessor. The chain only needs to receive the returned calculation results, and its correctness is determined by ZK proof guarantees, and ultimately enables trusted off-chain calculations of complex tasks.

Mystiko is a base layer of Web3, functioning as a universal ZK SDK to enhance the scalability, interoperability, and privacy of blockchains. Mystiko's Software Development Kit (SDK) allows developers to build blockchain applications, thereby reducing costs, enabling easy expansion, secure cross-chain interactions, and protecting users' on-chain identities (account balance, transaction history, etc.). It uses a technology called Snark of Snark to increase its security and reduce its gas fees. Mystiko.Network has integrated ZK Rollup, reducing transaction costs on the mainnet by 50-90% compared to other major existing ZK solutions.

Ethereum's need to scale has led to the development of Layer 2 solutions, with ZK/OP rollups emerging as key players, forming a short-term OP and long-term ZK consensus, highlighting ARB, OP, zkSync, and StarkNet as major contenders. Web3 users prioritize privacy only when it provides economic value. FHE's encryption cost further burdens the already low on-chain efficiency, and large-scale adoption is feasible only when significant benefits justify the cost. For institutional clients needing public blockchains but unwilling to disclose all information, FHE's ability to display and trade ciphertext is more suitable than ZKP.

This article explores blockchain and cryptocurrency concepts, their associated risks, and common fraud schemes. From the basics of blockchain technology to potential scams in cryptocurrency trading, it offers comprehensive insights and preventive measures to help readers protect their assets and interests.

The popularity of BRC-20 tokens is bringing the Bitcoin ecosystem back into the public. The SRC-20 standard and the STAMP protocol are also gaining interest. This article lists seven websites to help you understand the SRC-20 protocol in detail.
