About the authorParticle Network (https://particle.network) is at the forefront of Web3 innovation with its Modular L1 powering Chain Abstraction. After successfully integrating Wallet Abstraction into 900 dApps, serving 17 million users, Particle Network is unifying the Web3 experience through its Cosmos SDK Layer-1. This empowers Universal Accounts, Universal Liquidity, and a Universal Gas Token across diverse ecosystems, such as BTC, SVM, IBC, and EVM. Vamient Capital (https://vamient.xyz) is a quant fund specializing on trading on-chain with strategies deployed across multiple chains. As a market maker, Vamient specializes in making for order books, JIT liquidity for AMMs and can work with different hybrids in between, running liquidations and keeper bots for lending and collateralized protocols. Vamient looks to be a strong partner with new ecosystems to leverage on our niche in HFT and will be interested in contributing to lower spread, higher price stability and higher trading volume.RESEARCHES & CONCEPTSBitVMX from Rootstocks Whitepaper RootstockLabs @RootstockLabs .@SDLerner just unveiled the new BitVMX whitepaper at @btcplusplus Austin! It details its design, challenge-response protocol, and simplified programming model. By eliminating intricate data structures, it streamlines verification and reduces overhead. rootstocklabs.com BitVMX Whitepaper Explained: A CPU for Universal Computation on Bitcoin - Rootstock Labs Deep dive into the technical details of the whitepaper, including key features of BitVMX, potential use cases, and future directions. 40 23:54 • 1 thg 5, 2024 Researchers from Rootstock Labs and Fairgate Labs have announced the whitepaper of BitVMX, an open-source project aimed at advancing computations on Bitcoin. BitVMX is a new design for a virtual CPU that can verify arbitrary programs on the Bitcoin blockchain. It improves on the original BitVM concept by introducing an advanced challenge-response game protocol with a simplified computational model for verification by using hash chains of program traces instead of Merkle trees. BitVMX aims to enable sophisticated computations on the Bitcoin blockchain without requiring significant changes to its existing infrastructure. It has potential applications in creating decentralized, trustless bridges for Bitcoin sidechains and enabling the optimistic verification of zero-knowledge proofs. Link to the whitepaper: https://bitvmx.org/files/bitvmx-whitepaper.pdfNubit's Stateless and Trustless Execution Layer for Meta-protocols Nubit @nubit_org It is known that Bitcoin's lack of Turing completeness has traditionally restricted program logic execution. Therefore, we're thrilled to unveil our latest breakthrough: A stateless and trustless execution layer for meta-protocols on Bitcoin. 35 23:39 • 19 thg 5, 2024 The Bitcoin ecosystem has evolved over the past couple of years with advancements like Layer-2 solutions and the integration of inscriptions and ordinal protocols. However, Bitcoin's Turing-incomplete script necessitates the use of off-chain Bitcoin indexers, introducing challenges to data integrity and availability. To address these, a new modular indexer architecture, Indecure, is proposed by the team at Nubit. It uses polynomial commitments to streamline verification processes and robust data attestation procedures to ensure reliability against malicious alterations. Preliminary evaluations show Indecure's effectiveness in reducing computation time and data block size while maintaining high integrity in state transitions.TAP introduced the Privileges Authorities feature Trac @trac_btc A new version of the TAP Protocol w/ Privilege Authorities has been released. Privilege authorities allow for token/unats/collectible allowlists, launchpads, burn-bridges and more. This update requires all users of the TAP Reader to upgrade. The activation of the new feature… 379 7:48 • 28 thg 4, 2024 This new feature on TAP Protocol generates inscription texts to establish privilege authorities. It can be used by projects to implement whitelists, launchpads, and reward systems for games. By issuing tokens in this manner, projects can distribute tokens to their target users without concerns about front-running and sniping. The Royal is the first collection that utilized Privileges authorities.BTC L2's Landscape by Caliber.build Caliber Venture Builder @CaliberBuild #Bitcoin #Layer2 Landscape Report by @CaliberBuild Explore how sidechains, peg mechanisms, and rollup protocols transform scalability, security, and functionality.

This includes basic BTC scaling methods, the challenges, and the technical architecture of several prominent L2 solutions available in the market.Security of Stroom Networkhttps://blog.stroom.networkStroom Network's Security Fortress: A Closer LookExploring Stroom Network's architecture and strategic approach to security, transparency, and trust.Stroom Network aims to redefine DeFi security standards by integrating Bitcoin, Ethereum, and the Lightning Network to ensure secure and trustless operations. It uses a K-of-N multisig model for enhanced transparency and security. Within the Stroom system, all LN nodes must adhere to the Stroom protocol, which prevents them from accessing the Bitcoin in their channels and requires system validation for any channel state changes. Nodes must also report any revoked channel states to the validating nodes' databases. This allows the Stroom-enabled hub to securely link to the federated Lightning Network Node, managed by the validating nodes. Any non-compliant LN node can be excluded from the network, maintaining system integrity and security. Stroom's consensus mechanism uses the FROST algorithm, allowing validating nodes to independently verify operations. Key activities such as stroomBTC minting and redemption involve multi-party signatures stored in local databases. These databases synchronize through a Practical Byzantine Fault Tolerance-style consensus mechanism, ensuring censorship resistance. To bridge Bitcoin and Ethereum, each validating node incorporates full nodes for both blockchains, functioning as a DAO-managed LN Watchtower, enhancing network security and integrity. Stroom also employs a DAO structure for distributed governance, allowing community involvement in decision-making. Future plans include regular audits by third-party security firms and dynamic bug bounty initiatives.NEWS & LAUNCHESBitcoin Asia 2024 Alphas Luna Labs @LunaLabsVC You probably missed the alpha from $BTC Asia 2024.
