You are in a market that does not let you Sell. Imagine a market that sells coffee beans, and you are one of its registered sellers. You have good beans, lower prices, better packaging, etc. But.... You are unable to sell. Why - coz buyers never see you. Why? Because in this market, buyers do not browse. Every buyer request goes through a discovery desk, and the operator sitting at that desk decides which sellers a buyer is shown. So you walk up to him and ask why you are never on that list: - You: Why do buyers never see my shop? - Operator: Because you do not rank high enough in seller's. - You: What do I need to rank higher? - Operator: Sales volume, and a list of customers who have already bought from you. - You: But I can only get those if buyers find me and buy from me first. - Operator: Correct. And buyers only find you once you rank high enough. Meanwhile, the largest coffee seller in the market has already taken that order. The buyer never saw your shop. The operator says - "not my problem" The market worked exactly as designed. Would you keep selling in that market? Would you tell another merchant to come and join you in it? That is the condition of open agentic markets today. Today, the open agentic commerce market is killing its own merchants - and hence the market itself. article below 👇

Solidity v0.8.34 out now. This release fixes a high-severity bug in the IR pipeline affecting versions 0.8.28 through 0.8.33 (`--via-ir`, not enabled by default). If your code does not use both `--via-ir` and delete on a transient state variable, your contract is not affected.

Coding theory is such a cool field. For those who don't know, it's the math/engineering behind QR codes work and how CDs can get scratched but still function -- as well as some ZK algorithms. It ties together cs, linear algebra, probability, and a little abstract algebra together in a very applied (non-theoretical) setting. Kind of a shame most universities don't offer a course in it. Someday we'll have it on RareSkills/RareCode, and I'll relentlessly shill why you should learn it.

UNITED ARAB EMIRATES DID NOT BAN BITCOIN. Nothing... Absolutely Nothing in this report says that UAE banned Bitcoin. This literally is just an engagement farming post. Nothing in the report says Holding Bitcion or self-custody is a crime. what it says: 1. All of the guidelines by Central Bank Law entities/financial institutions that facilitate crypto transactions , not individuals. 2. Exchanges ( binance, bitoasis, bybit, etc ) must comply, obviously. 3. marketing or promotions for offering digital currency services are now regulated - good thing. 4. Crypto payment services need a lisense to operate - for businesses accepting btc/digital currencies - they do need regulatory approval. 5. all penalties mentioned are applicable only to: -> unlicensed financial service providers ->unlicensed exchanges ->firms offering payment services ->firms offering custody, brokering, dealing, promoting -> entities offering financial services via apps/dApps without approval and bdw, most of this was true before this report as well. - Holding/owning BTC is not illegal - Self-Custody is not illegal - Engagement Farming at this level should be illegal.
UNITED ARAB EMIRATES BANS BITCOIN I have bad news for all crypto habibis in Dubai, it's real. The New Central Bank of the UAE Law was issued in the Official Gazette and became legally effective as of September 16, 2025. The law in particular makes it a crime to offer any "tools," which include self-custodial Bitcoin wallets, blockchain explorers, and coin market cap sites, to United Arab Emirates citizens without a license. "Importantly, this goes beyond simply prohibiting the carrying out of regulated activities without a license; it now expressly captures the facilitation of such activities, either directly or indirectly. This means that entities providing technological infrastructure, platforms, protocols, or digital tools that enable or support the delivery of financial services may themselves fall within the regulatory perimeter, even if they do not directly offer the underlying financial products or services." No wallet. No Bitcoin. No problem. Even if no indirectly. Only Bitcoin you are allowed to own is one permitted by Central Bank of UAE. The punished for breaking the law is jail time and fine up to 136 147 039,00 United States Dollar. "Article 170 introduces a new criminal penalty for such conduct. Persons that engage in a licensed financial activity without a license may face imprisonment and/or a fine between AED 50,000 and AED 500 million, representing a significant increase over the penalties available under the 2018 Law. This is a notable development, and we may see increased enforcement in light of this new framework." This should not come as a surprise, since the UAE has a repressive government with a rich history of limiting freedom of speech and freedom of the press. If you have ever visited the country, you know that even WhatsApp calls do not work. en.wikipedia.org/wiki/Human_… Earlier, such attempts to make self-custody illegal were made in Estonia, Seychelles (as pressed by FATF) and in the EU. Find my last years Devcon presentation about the topic in the next tweet. As reported by @gibsondunn by Sameera Kimatrai and Aliya Padhani. gibsondunn.com/uae-central-b…
