Bool Network functions as a witness bridge, requiring only a signature on the target chain to complete the cross-chain transaction at minimal cost. Its core advantage is that nearly all operations occur within a Trusted Execution Environment (TEE), ensuring that external parties cannot see what is happening. Each node is unaware of the identity of the witnesses or whether they have been selected, which fundamentally prevents collusion and greatly increases the cost of external attacks.

The competition for TVL, the stacking concept, and a fifty-fold increase in a single day have made Bitcoin Layer 2 one of the most exciting and chaotic arenas. The main reason for this chaotic situation is that Bitcoin Layer 2 has yet to have a definitive definition.

As the demand for privacy protection grows, TEE technology has once again become a focal point. TEE provides a secure execution environment independent of the main system, protecting sensitive data and code. Multiple blockchain projects, such as Flashbots, Taiko, and Scroll, are exploring TEE applications to achieve private transactions, decentralized block building, and multi-proof systems. While TEE offers advantages in security and privacy, it still faces centralization risks. In the future, it may need to be compatible with more hardware vendors and set node ratios to reduce reliance on a single supplier, thereby further enhancing decentralization.

During the Spring Festival of 2024, an experimental protocol called ERC404 and its first project, Pandora, quickly became a sensation.

This article provides a comprehensive overview of the BEVM ecosystem, consisting of 20+ projects, and explores the development status of this BTC Layer 2 ecosystem.

SOON Network introduces a Merkle tree structure within the Solana Virtual Machine (SVM) to address the issue of missing global state roots. This enhancement strengthens SVM's capabilities in integrity verification, fraud proofs, and cross-layer operations within the aggregation system. By embedding the state root directly into the SVM blockchain, SOON improves security and scalability, providing stronger support for SVM aggregation.

This paper explores the diversity and application scenarios of DeFi leverage through dYdX V4, analyzes code level vulnerabilities, and puts forward the key security points of the leverage protocol.

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.

This article delves into Singularity, including the current state of the competitive landscape, the project's technical architecture, and an analysis of its advantages.

BOB is creating a hybrid solution that lets users withdraw assets via Bitcoin transactions without relying on Ethereum. It uses Ethereum for data availability and Bitcoin for censorship resistance. Users store withdrawal data in Bitcoin’s Taproot outputs and complete transactions with a two-phase commit/reveal process.

The restaking protocol offers new solutions to many issues and is an important narrative within the liquidity staking derivative track. The following article briefly discusses ‘restaking’, as well as some underlying implementations and security risks.

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-

The re-staking protocol proposed by EigenLayer has recently gained significant attention. It offers novel solutions to various issues and has become an important narrative in the liquidity staking derivatives race. This article delves into "re-staking," its underlying implementations, and associated security risks.
