CKB Dev↾⇃

AMA time again! This time with Retric from the DevRel team 🛠️ Retric has been part of Nervos' journey since the early days of CKB. Lately he's been building fun experiments on Fiber, such as Fiber Audio Player (a self-hosted podcast with streaming micropayments) and Fiber L402 (L402 paywall demo). Got any questions about CKB, Fiber, developer tooling, or what it's really like building these? Drop your questions on Reddit! reddit.com/r/NervosNetwor… and we'll see you on May 12th 👋 @FiberDevs #ckb #nervosnetwork #fibernetwork

👷 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/… @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 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/…

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.html 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/… 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/o…), 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-… The Nervos talk post for more background info: talk.nervos.org/t/obscell-wall…

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/… @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

☕️ #TeamCKB Major development updates in this sprint: - Shipped CKB v0.204.0 with native proxy / onion support - Released OffCKB v0.4.3 & v0.4.2 - Ongoing improvements on the light client and Rust toolchain On the VM side, added CFI extension support, including compiler (LLVM) runtime updates, fuzzing tests, and docs. Full log: github.com/nervosnetwork/… @CKBDevrel @NervosNetwork

🧅Tor / Onion networking, now in CKB v0.204.0: Privacy, reachability, and censorship resistance—Tor improves node behavior in three ways: - IP privacy: no direct exposure of your real-world address. - Inbound reachability: accept peers without port forwarding. - Censorship resistance: harder to block, harder to observe.

CKB update time 🎧☕️ This sprint we primarily focused on reliability & efficiency On CKB: - A default time-cost limit is added on indexer RPC to help keep heavy queries in check - Relay now sends messages asynchronously, so network congestion won't drop them On Molecule (serialization framework): You can now build any Molecule type from an iterator or `Vec`, with automatic item type conversion And RISC-V CFI support is coming to CKB-VM for extra control flow security. All the details here: github.com/nervosnetwork/… @CKBDevrel @NervosNetwork

Another experimental demo is out🌱  Join Airdrop — a lightweight airdrop-lock contract where users fund their own Cells first to register for the airdrop & receive tokens. Built entirely in TypeScript. What it solves: In CKB's cell model, airdrop issuers typically need to provide extra CKBytes so receivers can accept tokens. Join Airdrop flips this around — users join first and prepare their Cells themselves, making token distribution a lot smoother. It's a simpler, more scenario-specific alternative to the more general AnyOneCanPay script: github.com/cryptape/anyon…. 🪂 Try it out: join-airdrop-app.vercel.app 🐙 Repo: github.com/RetricSu/join-… 🙋Got ideas or feedback?
