@CKBdev  

 📣 CKB's 2nd Hard Fork Meepo is now live on testnet!  

This upgrade highlights the powerful Spawn syscall, enabling scripts to call child scripts within the same execution context—much like the POSIX spawn. 
Spawn empowers developers to build complex dependencies and smart contract libraries, advancing DApp sophistication on CKB.
(Learn more about Spawn: github.com/nervosnetwork/rfcs/blob/master/rfcs/0050-vm-syscalls-3/0050-vm-syscalls-3.md#spawn)

It also adds "data2", a new JSON representation matched by data hash.

Stay tuned as we get closer to mainnet!

⚠️ To join the CKB testnet, use CKB binary v0.119 or above: github.com/nervosnetwork/ckb/releases/tag/v0.119.0  

 Nervos Docs v2.12.0 is out!

 ✨ Just rolled out a fresh batch of updates to Nervos docs

Solid improvements for devs building on CKB include:

- Refactored dApp tutorials with offckb v3 and CCC SDK 
  (Transfer CKB, create DOB, store data on Cell, issue xUDT, simple lock tutorials all updated)
- Quick start guide now uses offckb v3
http://docs.nervos.org/docs/getting-started/quick-start
- Ensured Cells hold at least 61 CKB in examples in How CKB Works

Phew. Busy couple of weeks.🤪

- CKB v0.118.0-rc2 is out, bringing the preview chain to life, giving devs and miners the testing environment for the upcoming CKB hardfork, Meepo, on its Oct 15 launch.
- Also rolled out Onion Message encryption on Fiber. 
Lots more to come!

 IPFS on CKB ??🤔 New protocol idea open for discussion: 

Storing files on-chain can be tricky. 
Solutions like Ordinals and DOBs on RGB++ inscribe content on BTC witnesses, but they share some downsides:
- No oracle guarantees
- High costs
- Cross-chain infrastructure complexity even with a native dApp on CKB

This led to the design of CKBFS, leveraging CKB's type system & programming model—built to be simple, flexible, usable, and reproducible.

Thoughts? 💡
