We usually talk about code here. ⚙️🐛
But this time, got any questions about how what we build gets explained to everyone else?
Stefan, who leads CKBA's Content & Communications team, is doing an AMA.

The monthly #CKB development log is out:
This cycle focused on reducing failure cases across the node and light client, while several larger architecture changes continue to be reviewed.
CKB-VM v0.24.15 was released this month, with follow-up fixes to runtime behavior. The light client also added stricter checks for headers, proofs, and peer checkpoints, so invalid or inconsistent data can be rejected earlier.
On the node side, the team fixed issues around indexing rollback, networking edge cases, and dependency security. More protections are also being reviewed for transaction queues, sync responses, block relay, and request limits.
Some longer-term work is still in progress: the tx-pool redesign, a new RocksDB layout, and initial QUIC integration are all under review rather than released. DAO treasury and voting work also remains at the research and PoC stage.
There are also new docs for developers working with ckb-std and Rust script templates.

#CKB monthly development log (August)
This cycle brought CKB v0.209.0, Tentacle 0.7.7, and a range of reliability and security improvements across the node, networking stack, and light-client.
- CKB v0.209.0 shipped with tx-pool, Tor, and memory-growth fixes
- Tentacle 0.7.7 fixed a QUIC compatibility issue
- Light-client verification got stricter around proofs and downloaded block data
- Improvements to ckb-cli and contract development tooling
- Advanced a batch tally settlement solution (currently in design/PoC) for DAO Treasury & Voting
We also closed the previous tx-pool pipeline prototype and the next tx-pool design is moving toward an invariant-driven validate → plan → apply → effects model.

CKB monthly development log (June)
It's one of those months where you fix a bug, review a PR, merge a patch, and somehow come back to find the queue even longer than when you left... 🫣
Highlights include:
- CKB v0.207.0 release, security hardening across CKB, the light client, and the network
- Major progress on QUIC transport
- Continued DAO treasury and voting research
- A series of three educational write-ups on CKB-VM
- Security fixes reported through the bug bounty program--Shoutout to those who helped us find issues and make CKB stronger! 🙌
We also continued strengthening our security workflow. As AI-assisted security tools become more capable, the bar for code security keeps rising. We're integrating more of these tools into our development process to catch issues earlier.
But anyway, we're excited to finally share this month's dev log: github.com/nervosnetwork/ckb…
We just launched a dedicated AI Resources page to make onboarding AI coworkers to CKB easier.
Everything in one place: LLM files, agent instructions and skills, starter prompts, and the CKB AI MCP server.

@NervosNetwork @CKBDevrel
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.

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.

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.

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.
