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#

Four layers, one stack. Resource sourcing, structuring, tokenization, distribution, built end to end. MPC isn't a tech platform bolted onto mining. It's the full path from raw resource to on-chain yield, standardized at every layer. One stack, four layers. See the full stack.

Bitcoin layer-2s are entering a more serious phase. The recent @CoinDesk piece on Botanix's shutdown raises an important question for the sector: does the market want programmable BTC for its own sake, or products that solve clear financial problems using Bitcoin? For us at @RootstockLabs, the answer is increasingly clear. Users do not adopt infrastructure because it is elegant. They adopt it because it gives them access to real utility. As @dieguito said it: "Building an ecosystem is more like settling a new city than it is like launching a new application." Programmability on $BTC isn't the destination. It's the starting point. Rootstock has run EVM-compatible smart contracts secured by Bitcoin since 2018. What matters is where you point that capability: at financial problems Bitcoin's security and settlement are uniquely suited to solve. That's where we keep building. BTC-backed lending. Transparent, protocol-based products. Institutional-grade Bitcoin finance, where users can verify what's happening on-chain.
