To counter inevitable outrage over sending tax docs to LLMs: - We shared docs with our CPA, who doesn't have robust infosec practices - I'd upload the outputs to LLMs for verification anyways If you're so inclined, you could replicate this setup with local LLMs in OpenCode

Onchain builders, your next growth hack is staring you in the face 🫢 Every successful consumer app scales through an untapped distribution channel: Airbnb -> Craigslist Tiktok -> Facebook ads World is onboarding millions of *real* humans through partnerships with Razer, Tinder, & more. Take advantage while you still can!
What's the #1 challenge for onchain apps? 🙋🏾‍♂️ USERS 🙋🏻‍♀️ The solution? Build a Mini App on World App with us and get real users. The @worldnetwork ecosystem connects you directly to 12M+ verified/unique humans. No bots. No manipulation. Just real people ready to use what you create. 🪄

AI needs more compute. Decentralized compute helps with scaling, but requires coordination. Gensyn is solving this exact problem. Congrats on the Testnet launch!
Introducing the Gensyn Testnet The Gensyn testnet is live. Run a node, train your personal model, and track your participation in the swarm.

Huge fan of Celo. They've been focused on real world utility from the beginning. Today, Celo is #6 in Active Stablecoin Addresses - powering millions of users across Nigeria, Ghana, and Kenya 🌐 Excited to continue that progress with their migration to an L2!
Celo 🤝 @Alchemy Alchemy will support Celo L2! This is just the start of Alchemy on Celo, with a suite of powerful tools coming soon to the faster, more secure, & more composable Celo 🧰 🛠️ Keep reading to learn more about what's next↓

Anyone working on next gen hardware for vision impaired folks? Haven't seen anything super compelling yet. Happy to user test, invest, advise, etc. Feature set: - earbud - front facing camera - local llm that helps you navigate around safely ("red light coming up", "3 steps here")

Predatory lending practices are bad, but capping interest rates is not the answer - folks will lose access to credit. Would be more consumer friendly to prevent people from spiraling into debt. Some ideas: - limit $ amounts of high interest debt - limits based on % of net worth or income - limiting rollovers
🚨 Congresswoman Anna Paulina Luna (R-FL) is working with Congresswoman Alexandria Ocasio-Cortez (D-NY) to cap credit card interest rates at 10%. This is a good thing.

Sitting in the back seat of a Tesla is unbearable 🤢 Big fan of the car, but the aggressive regen braking makes for a terrible passenger experience.

Super proud of our team's work on this alongside @flashbots_x @worldnetwork! In a world of AI agents, PBH helps humans level the playing field. Long-term, Rollup Boost provides a framework for rollup extensions. Imagine an "Encrypted Mempool" extension that keeps txes private 🤯
The Priority Blockspace for Humans testnet took months of hard work from our RaaS and Wallet teams, @worldnetwork and R&D partner @flashbots_x — all on managed infrastructure from our Rollups platform! Some technical highlights we're proud of: ☑️ Our Rollups platform now supports Flashbots Rollup-Boost, enabling custom block builders ☑️ PBH is powered by a combination of stateful ERC-4337 signature aggregation (enabled by our Rundler) and verifiable priority ordering (enabled by World’s custom block builder) ☑️ Our ERC-4337 Bundler has a custom signature aggregator to group verified human user ops together, concentrating their proofs as an aggregated signature and submitting them as a bundle transaction. ☑️ The signature aggregator's signature can verify that each user ops bundle is a verified human and the transaction deserves block priority (enforced by the custom block builder) We’re just at the start line of the PBH roadmap. Protocol devs and security researchers: there's up to $40K in USDC bounties available for breaking PBH invariants. Start breaking now!

Markets are down, but last week was the most bullish I've had working in crypto. Keep building!

Crypto is a global religion 🌎 Last week, I heard my 27 yo Taiwanese cousin perfectly explain Bitcoin to his 58 yo mom. "Bitcoin is like gold, not like government currency" ☑️ "Bitcoin can't be debased, it's written in code" ☑️ "I'm all in on MicroStrategy" 😂
