The focus of the Bitcoin ecosystem's development lies in supporting market activities. Mainstream Layer2 solutions include the Lightning Network, sidechains, and Rollups. The Lightning Network enables peer-to-peer payments by establishing off-chain payment channels, while sidechains achieve this by locking Bitcoin assets and minting equivalent assets on the sidechain. Within the Bitcoin ecosystem, there are also stablecoin protocols and various DeFi projects. Unlike Ethereum, Bitcoin's Layer2 solutions offer multiple choices. The Lightning Network has the potential to achieve high TPS (transactions per second) but carries centralization risks. Sidechain solutions, similar to Ethereum, can issue assets equivalent to Bitcoin at a 1:1 ratio. Additionally, there are various cross-chain bridge solutions and Bitcoin-based DeFi protocols, such as B2 Network, Merlin Chain, and Alex. The Bitcoin ecosystem will serve as a crucial engine for this bull market, with various DeFi protocols, stablecoin protocols, and cross-

Dive deep into B² Network, BTC Layer 2's EVM-compatible solution, leveraging ZK-Rollup technology to promote the development of the Bitcoin ecosystem and unlock untapped potential.

B^2 Network is a decentralized Data Availability (DA) and storage platform that addresses data compression and verification issues using an off-chain DA network. It aims to reduce dependence on the Bitcoin main network. The B^2 Hub functions as a DA layer and off-chain verification layer, similar to Celestia, to prevent data withholding and other malicious activities. In the future, B^2 Network plans to incorporate Bitcoin Layer2 to establish a universal DA layer and data storage layer within the Bitcoin ecosystem. The B^2 Hub node validates transaction batches, while storage nodes compete for block production rights to earn incentives. The workflow of B^2 Network involves the sequencer creating new blocks, the aggregator sending them to the Prover for ZK proof generation, and the B^2 Hub node verifying and transmitting the data hash to the Bitcoin chain. As a universal DA and verification layer, B^2 Hub has the potential to enhance other Bitcoin second-layer solutions.

B² Network, a layer-2 solution on the Bitcoin Blockchain addresses the scalability of the Bitcoin network by introducing a two-layer infrastructure that allows for faster transactions and lower costs without compromising on security.

The rise of Bitcoin Ordinals has injected new vitality into the Bitcoin ecosystem, reigniting interest in Bitcoin. This has also led to the emergence of many new Bitcoin Layer 2 projects. This article selects four of the most popular projects on the market: BEVM, Merlin, B² Network, and BounceBit, to interpret their highlights and advantages.

B3 is a horizontally scalable game ecosystem based on Base, aimed at promoting the development of on-chain games by providing high-performance, low-cost blockchain infrastructure. As a Layer3 ecosystem, B3 can support high-frequency transaction processing per second and approach the realization of a transaction environment with extremely low Gas fees.

Through unique technical solutions, projects such as Merlin, B² Network, BEVM and Bouncebit have improved Bitcoin’s scalability, transaction efficiency and application scenarios. BTC L2 is showing a flourishing trend, indicating that it will reach new heights in scalability, transaction efficiency, security and ecosystem diversity in the future.

This article takes stock of Bitcoin Layer 2 projects, including Rollup, side chain, DA, AI, etc.

This article delves into the ENS (Ethereum Name Service) V2 release, which extends domain services to Layer 2 (L2) networks, aiming to reduce transaction fees and improve processing speeds. It explores the new features of ENS V2, including the new hierarchical registry architecture, the introduction of a universal resolver, and support for L2 networks. Additionally, it discusses the migration process to V2 and its potential benefits, such as lower fees, higher speeds, and more flexible domain management.

This article introduces N2 (Niggachain AI Layer 2), the world's first AI-driven Layer 2 blockchain solution. N2 combines AI technology and quantum computing resistance to address the limitations of traditional blockchains in scalability, transaction speed, and cost. Its core technologies include '0-second block time', AI-driven network optimization, and quantum-resistant security protection, aiming to improve transaction efficiency and ensure system stability.

ENS is a well-known domain name service on Ethereum. It announced the V2 version of ENS on its official website: promoting the original domain name service to L2. This article will analyze ENS V2 for everyone through a technical whitepaper.

This article suggests that there is a theoretical "glass ceiling" for Layer 2 valuation, as Ethereum L1 ensures the security of L2 activities through its consensus mechanism, theoretically limiting the value of L2 not to exceed L1.

Two-factor authentication (2FA) serves as an additional layer of defense, demanding users to present two distinct forms of identification before gaining access to systems, accounts, or critical data.

This article explains the importance of objective and comprehensive risk assessment indicators for distinguishing different Layer 2 projects in the field of modular blockchain. Analyze security issues that may be encountered at different stages, explain why L2 projects such as Arbitrum and Optimism can maintain their current state, and discuss how these projects balance flexibility and security.

U2U Network is an innovative Layer-1 blockchain platform that aims to promote the global adoption of the Internet and blockchain through decentralized physical infrastructure network (DePIN). Its modular subnet architecture, Helios consensus protocol, and decentralized VPN (U2DPN) provide the network with high performance, security, and scalability.
