Bitlight Labs has completed its Bitcoin Infrastructure Modernization — upgrading from Bitcoin Core 28.x to v31.0 and deploying Cluster Mempool across our stack. Full technical write-up: What changed: → Cluster Mempool replaces per-transaction tracking with cluster-based evaluation. Transactions are now grouped and ordered by chunk feerate, enabling more accurate block template construction and stricter RBF semantics. → Fee estimation precision improved from 1 sat/vB to 0.1 sat/vB — reducing overpayment in low-fee environments for wallets and protocol-level settlement. → mempool-electrs upgraded to v3.3.0 with multi-tier fee estimation (fastest / halfHour / hour / economy / minimum), while preserving full backward compatibility with existing electrs endpoints. → Private broadcast support via Tor/I2P for transaction relay, reducing originating IP leakage. → Default dbcache increased to 1024 MB on 4GB+ systems, improving sync and validation performance. For RGB Layer2 infrastructure, this means more predictable CPFP/RBF behavior, cleaner fee selection for on-chain settlement, and a stronger foundation for commitment transactions. Our approach: stay close to upstream, reduce unnecessary abstraction, build where the protocol is actually moving. Make Bitcoin Smart.

AI Agents are evolving from assistants into autonomous on-chain actors. On May 24, OpenBuild and Mantle will host the Mantle Turing Test Hackathon 2026 Meetup in Shanghai, bringing together AI builders, Web3 developers, and creators exploring the future of Agentic AI × Web3. @Mantle_Official @0xMantle @0xMantleCN 💰 $120,000 prize pool ⚡ AI Trading, RWA, DevTools, Agentic Wallets, and more 🤝 Team matching and project networking This is not just a hackathon. It is an experiment in autonomous AI on-chain. 🗓 May 24, 2026 📍 Shanghai 🔗 #Mantle# #AI# #Web3# #Hackathon# #OpenBuild# #Shanghai# #Layer2# #ZK# #DeFi# #RWA#

LayerZero (@LayerZero_Core) is Building Zero For Institutional Finance Zero uses zero knowledge proofs to separate transaction execution from verification. Citadel Securities, DTCC, ICE, Google Cloud, ARK Invest, and Tether back the project. Read the full breakdown below:

LayerZero underperforms all other major crypto assets. According to CMC data, @LayerZero_Core's $ZRO token is down nearly -13% in the past week. This makes it the worst performing asset among the top-100 tokens on CMC, followed by @Stable and @Aptos. All three of these assets however are up over the past 24 hours.

Layer 1 secures. Layer 2 scales. ⚡ One strengthens the foundation. The other helps handle more activity with lower fees and faster transactions. Together, they're helping blockchains scale for the next wave of adoption. Learn more 👇

LayerZero just launched its own Exchange model @LayerZero_Core deploys ATLAS (Aggregated Trading Liquidity and Settlement), an “unhosted” exchange model that unifies matching, clearing, and risk management into one cohesive system. Built on Zero Chain technology, LayerZero’s ATLAS protocol is designed from the start to handle 200,000 transactions per second with sub-millisecond latency. It targets the $4.7 quadrillion securities settlements market currently served by legacy titans such as DTCC. ATLAS is available as both the Open and Institutional ATLAS variants and enables global markets to provide 24/7 markets in RWA, FX, and derivatives while retaining verifiable self-custody.
