CKB Dev↾⇃

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?

CKB update time ✅ - Shipped CKB 1.0.0 crates (ckb 0.204.0-rc1) & CKB-VM CFI extension (initial Rust-based interpreter support) - Core & Docker builder now use Rust 1.91.0; bootstrapper upgrade in progress - Improving TUI experience - Fixed a boot issue on Windows 10 flagged by the community — thanks for catching it! Full dev log: github.com/nervosnetwork/… 🩹 Tip: For huge run.log files, try logrotate (github.com/logrotate/logr…) and big-file editors for now. We'll be working on better log handling as chain data grows! @CKBDevrel @NervosNetwork

This sprint's dev updates: - Released ckb v0.203.0 — Rust SDK had some breaking changes; migration tool is ready 🔧 github.com/nervosnetwork/… Alongside it: - ckb-cli v1.16.0 - ckb-vm-contrib v0.203.0 Full log: github.com/nervosnetwork/… @CKBDevrel @NervosNetwork
