Introducing: Build on CKB! With the rapid growth of our CKBuilders programme, we've been devising new offerings to accommodate developers who are new to CKB and interested in learning. We now have the Build on CKB telegram channel for new developers to participate in weekly competitions to win prizes, receive devrel support, participate in peer learning, and get pre-hackathon preparation and support! We recently completed our first Build on CKB campaign, with 8 new developers all receiving CKB prizes! If you missed out, don't worry! We have a new campaign live now. Check it out on CKBoost: ckboost.netlify.app/campaign…

Straight from @Coinbase’s April paper on quantum computing and blockchains. 👇 “Crypto-agility is a highly recommended practice in general [...] even more so in the context of PQC.” Now guess which chains were designed to switch cryptographic algorithms without disrupting operations🧠 Hint: there’s only one.

CKB development log for May is out. This month focused mainly on maintenance, infrastructure, and long-term improvements across the stack. • CKB v0.206.0 release • Progress on DAO / voting research • Faster storage and sync optimization work • Reproducible build pipeline progress • QUIC networking integration in progress • Continued CKB-VM and light client maintenance Full dev log: github.com/nervosnetwork/ckb…

👷 Latest updates of CKB from the engineering side: Another month of refining the core and pushing optimizations, including improved CKB-VM ARM64 performance and ML-DSA work to help prepare for post-quantum standards. Also strengthening CKB-VM with a new differential testing framework to validate future optimizations. Other updates: - AI Tooling: Added SKILL.md for AI agents in ckb-debugger to streamline script debugging - Connectivity: Continued QUIC support for Tentacle to provides faster handshakes and better resilience against connection migration - Governance: Multiple DAO Treasury designs & voting directions under discussion - Maintenance: Upgraded toolchain to 1.95.0 and synced ckb-musl with upstream Full log: github.com/nervosnetwork/ckb… @NervosNetwork @CKBDevrel

We are excited to announce that QuantumPurse is expanding its scope with two new projects: 🚀 QuantumPurse V2 Building on the foundation of QuantumPurse V1, security is reimagined across every layer — from software to hardware. High-performance, feature-rich, and built natively for each platform. 🔐 Hardware Integration Building on the shoulders of Trezor, we’re integrating CKB and bringing quantum-safe crypto to the quantum-ready hardware wallet, Safe7.

CKB is entering a mature phase. Our work is shifting toward deeper optimization, faster verification, and reproducible infrastructure. Recent highlights: - Optimized SP1 verification: Reduced cycles from ~6000M to ~63M (~100x improvement) - SMT verification performance reached a production-viable level - ARM64 optimizations: streamlined Zba instruction handling by removing redundant ops Meanwhile, a new discussion is underway: Activating the Nervos DAO Treasury, exploring a shift to an on-chain, governance-controlled model Dev Logs will now move to a monthly cadence, reflecting a more focused, incremental development cycle.

CKB v0.205.0 (b75a785, 2026-03-17): - Terminal module for CKB-TUI - Proxy protocol support & cargo-binstall compatibility - Export/import: range & verifier selection - RPC logs subscription - Rust toolchain → 1.92.0 - Docker base → Focal - Security fix: RUSTSEC-2026-0007 (bytes) Full release ↓ github.com/nervosnetwork/ckb…

Recent CKB development work: - We implemented 4 optimizations in the Aarch64 RISC-V handler in CKB-VM and benchmarked their impact. Fuzzing is being added before upstreaming. - A feasibility study for verifying SP1 zkVM proofs directly on CKB is complete. The approach appears workable, giving CKB the ability to verify mainstream zkVM proofs on-chain. - The bn128 library for RISC-V 64 has been released, enabling more efficient elliptic curve operations inside CKB-VM. - QUIC transport support in Tentacle is under investigation. - On-chain governance in design.

Journey on that lobster is unstoppable.🦞 Following up the remarkable NerdMinerCKB solo miner, @wyltek1 launched a new site--hardware first, open source, built for the real world. 🦾🌏 Membership is completely free, and no personal details, no data collection. First 100 to connect get a founding member digital object minted straight to their wallet: wyltekindustries.com/members… Massive appreciation for constantly pushing the boundaries. The ecosystem speaks for itself. @NervosNetwork

OpenClaw🦞 Orange Pi 🍊 = ? Amazing work again by @wyltek1 on NerdMinerCKB--CKB's ESP32 solo miner! Forked the NerdSoloMiner, headed to bed... woke up to find the AI agent had ripped out SHA256 and dropped CKB's Eaglesong PoW overnight.🤯 Incredibly inspiring to see a solo builder hack together his own miner as a late-night personal project using AI. This is how grassroots decentralization and open-source are alive and well in Nervos.

Latest dev log is out: github.com/nervosnetwork/ckb… Two key updates 🛠️ CKB-VM gets a speed boost. Added RV64 Assembly Execution to CKB-VM—expect massive performance gains on #RISC-V and high efficiency within #zkVM environments. Privacy-preserving TUI wallet The new Obscell TUI wallet is live. Privacy via stealth addresses and confidential transactions —built in just one week with an AI agent. (Shoutout to Rea-Don-Lycn for the Obscell foundation) That's the CKB edge: native L1 privacy built into the architecture. No need for a dedicated chains like Zcash or Monero. One more thing--the AI shift AI agents are killing the barrier to entry. Ambitious side projects are now weekend builds. CKB ecosystem is moving faster than ever. @NervosNetwork @CKBDevrel

Been hacking on a small side project lately: Obscell Wallet — a privacy-preserving TUI wallet for CKB. It builds on the earlier idea of Obscell (by Rea-Don-Lycn github.com/Rea-Don-Lycn/obsc…), which explored: • Stealth addresses • Confidential Transactions (CT) on CKB Together, they create a privacy-enhanced UTXO token system with hidden amounts, unlinkable recipients, and controlled minting. But the original project stopped somehow at the CT part, and Quake @quake decided to finish it. With coding agents, the remaining CT implementation was wrapped up in just one week! Still experimental, but it runs on testnet now. Links: Obscell Wallet GitHub: github.com/quake/obscell-wal… The Nervos talk post for more background info: talk.nervos.org/t/obscell-wa…

Interesting read 👀 When it comes to post-quantum security, smaller blockchains often move faster--lower systemic risk, tighter communities, and less technical debt. This piece highlights that 12 blockchains, including CKB, have already migrated or have concrete plans to migrate to specific post-quantum signature schemes. For CKB, quantum resistance isn't a marketing checkbox. It's an architectural question. 👌

🔗Link update: CKB OpenRPC interactive docs, now available at: rpc-explorer.ckbapp.dev

#TeamCKB Dev log This sprint in CKB, we added an OpenRPC spec with an interactive browser (eval-exec.github.io/ckb-rpc), log subscriptions for real-time debugging, RV64IM assembly mode in CKB-VM, and improved RocksDB efficiency. We also released a TypeScript boilerplate for building CKB apps from smart contracts to UI. Write, test, deploy and interact with contracts using JS tooling.

#TeamCKB Dev updates: Longer gap than usual since the last update (holiday weeks ☃️). Here's a quick catch-up. Recent work includes: - Progress mode on mobile light clients with native Android support - Pushed a ~2.3× speedup in the VM with optimized SHA256 and SHA512 - Reduced SPHINCS⁺ verification costs by around 40%. - Shipped the quantum resistant lock script to mainnet For more technical details, check out the full dev log: github.com/nervosnetwork/ckb… @NervosNetwork

We've been talking a lot about tech here — Scripts, VM, protocols, optimizations ... Love that! But builders aren't just commit histories. That's why we started CKB Builder Story, a small series about the people behind the protocols. 🧑‍💻✨ Our first story features Tea (@teaplusplus11), creator of Quantum Purse (@quantumpurse), the industry's first SPHINCS -based quantum-resistant wallet. He has built across ecosystems: EOS, Bitcoin, Ethereum, and now CKB. Here he shares how he stumbled into CKB, why he decided to stay & build long-term, his appreciation for Proof of Work, and why good architecture good people matter. #nervos #pow #BlockchainDev
