An app user emailed @Texas_Twins_Dad about an error while they were out with family. Grok Bot handled it from A to Z: found the bugs, fixed them, and shipped on its own. So many use cases with Grok Bot.

You think you've mastered Claude. Here are 7 daily habits proving you haven't (yet): Mistake 1. You build folders and files for Claude. Fix: Delete them all. Folders leak old outputs and poison your context. Your entire setup is Skills + Projects. Nothing else. Mistake 2. You maintain an about-me file. Fix: Turn it into a Skill. One /command loads who you are, only when you invoke it. Zero maintenance. Mistake 3. You try to write the perfect prompt. Fix: Write a lazy one & add "use AskUserQuestion." Claude interviews you, you click the answers, and it keeps asking until it's impossible to fail. Mistake 4. You type your prompts. Fix: Hold Shift and talk with Wispr Flow. You type at 60 words per minute. You speak at 150. More yapping = more context = better output. Mistake 5. You check Gmail by hand every morning. Fix: Plug Connectors into Gmail, Slack & Granola. One morning summary: what to reply to, what's slipping. Click. Done. Mistake 6. You build spreadsheets cell by cell. Fix: Drop your CSV into Cowork and describe the output. Claude writes the formulas and builds the model. One click sends it straight to Google Sheets. Mistake 7. You redo the same task twice. Fix: The second time you run it, say "make it a skill." And when you have no idea where to start, /how-to plans everything from A to Z. To download my (exact) Claude Skills: Step 1. Go to Step 2. Download the skills. Step 3. Put your email and verify with an OTP. Step 4. Save the downloaded zip file. Step 5. Upload to Claude → Settings → Skills.

Come to Zug, they said. It’s the Crypto Valley, they said. It may be home to a ton of crypto organizations, but who’s still here building exciting things on Ethereum? Let’s find out. Zug Ethereum Meetup #0#, September 7:

LayerZero’s Zero chain passes a regulated trading test @tradeon21x, the first EU venue licensed to trade and settle tokenized securities on a blockchain, spent a month running its order book on a private version of Zero, LayerZero’s new chain. The pilot traded US stock tokens, with each order matched and settled onchain in a single transaction. @LayerZero_Core ($ZRO) says the test reached 10,000 order matches per second, up to 45x faster than an unnamed layer 2 setup used as a baseline. 21X’s live exchange in Europe still runs on its existing systems, and it has not announced a move to Zero.

Adding ZK to @Arbitrum BoLD protocol was surprisingly simple. How does it work? Today, BoLD settlement works like this: → Proposers can make assertions (a claim about the chain's new state); when a new assertion comes in a challenge timer starts → No rival assertion within the challenge window? The assertion is confirmed → Rival posted? The challenge protocol kicks in New multi-prover path (everything above still holds, plus): → A proposer can prove any unconfirmed assertion with a ZK proof + K-of-N attestations from the Fast Confirmation Committee → ZK proof verifies on the parent chain & enough attestations check out? The assertion settles early - no waiting out the challenge window Why this beats a ZK-only design: 1. Multi-prover security: Fast confirmation needs two independent systems to agree: a ZK proof verified on the parent chain + attestations from committee nodes re-executing the chain. To fast-confirm a bad state, an attacker has to break both at once. TEE-run committee nodes are planned as a further hardening step. 2. Deterministic upper bound on settlement: If the prover stalls or has a bug, the chain simply falls back to optimistic settlement: slower, never halted, funds untouched. A ZK-only chain in the same spot may never settle without security council action. 3. Pay for proving only when you need it: Proving is optional per assertion: pure fraud-proof chains pay nothing, Hybrid ZK chains proves on demand to settle early or resolve disputes, and ZK Prove All chains prove everything for always-fast settlement. ZK-only stacks have one mode: prove every batch, forever. @Offchain will bring a proposal to the DAO to upgrade Arbitrum One to ZK settlement, and other chains built with Arbitrum Platform will be able to upgrade at will. Stay tuned for more 👀

A marketplace, especially one dedicated entirely to Zcash and closely connected to its ecosystem, could grow into a major digital commerce hub in the future. Once we truly understand what Zcash adoption can look like, we’ll see that such a marketplace is more than just a place to buy and sell things. It can become a hub where hundreds of thousands of people discover products and services, connect with each other, and where the Zcash economy comes to life. We are building the foundation for that today.
