⚒️ No more tool juggling, just build. New guide: OffCKB—an all-in-one CLI tool for a local CKB dev environment
With OffCKB, you can:
* Set up a local Devnet with a single command
* Access 20 pre-funded accounts & minimal dApp templates for quick setup
* Leverage embedded Scripts, including Omnilock, xUDT, and Spore
* Streamline your workflow from Script building and deployment to frontend integration

TeamCKB Dev Updates
* CKB v0.119.0 is live with a new chain on testnet, to preview the upcoming hard fork
* Fiber Network improvements include enhanced self-payment, automatic initialization, and safeguard for checking CKB amount
* Ongoing work includes WASM support for CKB light client, a Rust library for automated IPC in CKB Scripts

📣 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
#TeamCKB Dev Log
- CKB now runs on the Tor network with `/onion` type address support
- Compiled CKB based on GNU Guix
- Released a type migration tool
- Integrated Sphinx for onion message obfuscation on Fiber network
🔛 We're also progressing on WASM support for Light Client and a new CKB on-chain script IPC framework powered by spawn.

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? 💡
