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’s Zero chain passes a regulated trading test @tradeon21x, the first EU venue licensed to trade and settle tokenized securities on a blockchain, spent a month running its order book on a private version of Zero, LayerZero’s new chain. The pilot traded US stock tokens, with each order matched and settled onchain in a single transaction. @LayerZero_Core ($ZRO) says the test reached 10,000 order matches per second, up to 45x faster than an unnamed layer 2 setup used as a baseline. 21X’s live exchange in Europe still runs on its existing systems, and it has not announced a move to Zero.

Layer 1 network @Aptos ($APT) burned 174,100 tokens in the past 30 days, taking the total since mainnet to about 1.9 million. Average fees remain about $0.0005 after a tenfold gas increase. Read more:

LayerZero wasn't playing around this week. @LayerZero_Core's $ZRO is one of few crypto majors to see price increases this week. The performance comes alongside some significant announcements - This includes @LoonFinance's decision to use LayerZero tech to power its @CADCstablecoin.

LayerZero Labs unveiled Zero, its own Layer 1 for institutional finance, on February 10, 2026. Citadel Securities made a strategic investment in $ZRO, and @LayerZero_Core says Zero can handle up to 2 million TPS per Zone. Why LayerZero built Zero:

LayerZero research tackles a big quantum problem for blockchains Blockchains verify thousands of validator signatures by bundling them into a single proof, but today’s method could be broken by future quantum computers. Quantum-safe signatures exist, but bundling them quickly has been hard. Aerie, new research from @LayerZero_Core with @a16zcrypto, Carnegie Mellon, and Imperial College London, bundled about 32,000 quantum-safe signatures in 0.65 seconds on a MacBook Pro. So far it has only been tested in benchmarks, not used on any live blockchain.
