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. Got questions for him? Drop them below ↓ teddit.net/r/NervosNetwork/c…

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.

🧅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. Run your node over Tor guide: docs.nervos.org/docs/node/ru… Config details: docs.nervos.org/docs/node/no… CKB v0.204.0: github.com/nervosnetwork/ckb… @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/anyone-c…. 🪂 Try it out: join-airdrop-app.vercel.app/ 🐙 Repo: github.com/RetricSu/join-air… 🙋Got ideas or feedback?

Another mini project out ☕️😎 Exploring what Web5-style payments could look like—Spillman Payment Channel—blending AI chat w/ off-chain micro-payments: - Chat with AI, pay per message automatically, off-chain - Web2-level friendly UX + Web3-level security & privacy - Using CKB's UTXO model for safe "sign first, settle on-chain later" payments Best part? Contract work all done in JavaScript! 🥳 Fun fact: this demo was built by a front-end dev new to CKB and even blockchain. Turns out you don't need to be a pro to get a payment system up and running. Of course, it's open source: github.com/HappySonnyDev/Spi… Also check out his development journey and see how a front-end dev tackled CKB for the first time: talk.nervos.org/t/web3/9621

We’re sharing how we debug flaky tests in CKB. 🕷️ You probably won’t hit this as a dApp builder— but it’s the kind of work that keeps the infra solid. So you can just build without worrying. 🔗 yakihonne.com/naddr1qvzqqqr4…

📦 Just built something I think you'll like: CKB-JS-VM. Now you can write on-chain scripts in JavaScript or TypeScript. It's powered by QuickJS, a lightweight JS engine, fully integrated into CKB-VM. You get to use one language for both development and testing, plus take advantage of the whole JS/TS ecosystem. 📕Here’s a little guide with tutorials if you want to dive in: github.com/nervosnetwork/ckb… @CKBDevrel @NervosNetwork

📣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/rfc…) 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… @NervosNetwork @CKBEcoFund @NervosNation

Nervos Docs v2.12.0 is out! - New tutorial: Creating a Simple UDT Script docs.nervos.org/docs/script/… - Updated CKB-VM syscalls & error codes docs.nervos.org/docs/script/… Shoutout to tea2x (GitHub) for the first contribution! 🫡 Details: github.com/nervosnetwork/doc… #Nervos #ckbusdt @CKBEcoFund @NervosNetwork

14/ CKB-VM, Script Execution & Cycles CKB-VM executes all on-chain Scripts using the RISC-V architecture for efficiency and flexibility. CKB-VM uses cycles to measure computational cost.

12/ There are two types of Scripts: - Lock Script: controls ownership and access to a Cell. Required. - Type Script: dictates how a Cell is used or modified. Optional.

9/ Confirm Miners add your transaction to a new block. Once mined, it’s permanently on-chain. At this point, it has 1 confirmation.

8/ Propagate After validation, the transaction is sent to other nodes and enters the mempool, awaiting confirmation by miners.

7/ Validate Nodes validate the transaction. Learn more about the validation process: docs.nervos.org/docs/getting…

6/ Broadcast Once signed, the transaction is broadcasted from your wallet to the nearest CKB network node.

5/ Sign You sign the transaction with your private key, proving your ownership of the CKBytes in the Cell.

4/ For example, sending 50 CKBytes from a 100 CKBytes Cell creates two new Live Cells: 50 CKBytes for the recipient and 49.999 CKBytes locked to yourself as your change, with 0.001 CKBytes as the transaction fee.

2/ Cells: From Live to Dead CKB uses Cells to store value and data. Cell holds CKBytes—the native token, representing both value and storage space. Unconsumed Cells are “Live”. Once used, they become “Dead.”

Nervos Docs v2.10.0 Update: 🌟 - Refactored "How CKB works" with new visuals—GIFs and images for better clarity: docs.nervos.org/docs/getting… - Introduced JavaScript/TypeScript SDK CCC—now the primarily recommended SDK for building on Nervos: docs.nervos.org/docs/sdk-and… @CKBEcoFund - Dependency bumps for security and stability Shoutout to new contributor: GitHub@fghdotio 🎉 Full details: github.com/nervosnetwork/doc… @NervosNetwork @Cryptape

Unlocking & Verification Process Bitcoin's locking Script, stored in the ScriptPubKey of the UTXO, specifies the conditions under which the token can be spent. In this case, it is defined as: OP_ADD <8> OP_EQUAL, demanding that two provided numbers sum to exactly 8 to validate the transaction. To unlock for spending, an unlocking Script must meet the conditions of the locking Script. In this example, OP_3 and OP_5 are provided. In CKB, the Scripting logic is implemented in a more versatile programming environment compared to Bitcoin’s stack-based Script. Here the same example is used where you want to spend a Live Cell locked by a Script requiring two numbers that, when provided, must sum to 8. Visit our documentation for an illustrated breakdown: docs.nervos.org/docs/getting…

BTC Script vs. CKB Script By comparison, CKB Script provides advanced functionalities, including extensive introspection, high-level language support, and smart contract capabilities, and cross-chain compatibility. For a detailed overview, refer to the table provided:

Bitcoin Script Interpreter vs. CKB-VM The Bitcoin Script Interpreter uses the stack data structure during Script execution, where temporary data is pushed (added) and popped (removed) from the stack. CKB-VM is powered by the RISC-V instruction set, providing a low-level access to the CPU. It enhances execution efficiency and flexibility, allowing any RISC-V-targeted language to be used for CKB development. The Script validates a transaction by loading values from the transaction data and returning 0 for a valid transaction or 1 for an invalid one.

Basic Unit: Cell vs UTXO A BTC UTXO represents the leftover funds after a transaction. If Alice sends 4 BTC to Bob from her 5 BTC, two new UTXOs are created: Bob gets a 4 BTC UTXO, and Alice retains a 0.999 BTC UTXO, with the difference going to miners as a transaction fee. UTXOs contain a single lock, the scriptPubKey, dictating the conditions for spending. Cells in CKB offer greater flexibility than UTXOs, capable of storing various data types including cryptocurrency, images, videos, and codes. Each Cell has: • Lock Script: defines spending conditions, similar to Bitcoin's `scriptPubKey`. • Type Script (Optional): defines conditions for Cell transformation or state transitions.

Tx Broadcasting & On-Chain Verification Clarification Needed! Hey dApp devs! We've spotted some confusion about the `send_transaction` RPC. Remember, receiving a transaction hash (`txhash`) does NOT indicate that your tx is fully verified on-chain, because `send_transaction` is asynchronous. To find out the tx’s state, always use `get_transaction` method. Checkout the updates and examples in the docs: How to Query Transaction State: docs.nervos.org/docs/how-tos…
