After four years of development and millions in funding, the layer-1 blockchain Aptos (APT) has finally launched its mainnet, though it has been marred by mixed reception. 
The much-anticipated proof-of-stake blockchain, dubbed by some as a “Solana killer” due to its claimed 160,000 transactions per second (TPS) has launched its mainnet on Oct. 17.
However, some members of the community have pointed out that the previously claimed TPS is falling far short of expectations on the mainnet.
According to Aptos’ blockchain explorer the network is seeing around 4 TPS at the time of writing, while some users on Twitter have reported not being able to send transactions.
Others on Twitter noticed the Aptos Discord was closed for a few hours after the launch of the mainnet, accusing the team was attempting to stop discussion around potential launch issues.
Cointelegraph reached out to Aptos for comment and was directed to a "Day one update" tweet by Aptos on Oct. 18. 
In the tweet, Aptos said the network is “performing as expected” with activity increasing as more ecosystem participants join. Cointelegraph was able to view a variety of transactions from users using its blockchain explorer.
Day one update:
Today has been exciting. Thank you for all the support!

The Aptos network has been performing as expected and will see increased activity as ecosystem projects onboard and get going.
— Aptos (@AptosLabs) October 18, 2022
Aptos also said it closed comments on its Discord and Telegram channels to “protect the community from scams” and they will “return to normal when appropriate.”
The tokenomics of Aptos is not yet publicly available, leading some to cite concerns that cryptocurrency exchanges such as Binance and FTX are listing its token without such information available to their customers.
Aptos has seen millions invested from venture capital firms with the most recent round of funding in July netting Aptos Labs $150 million, a prior round in March raised $200 million with participants including Andreessen Horowitz (a16z), FTX Ventures, and Coinbase Ventures.
Aptos Labs was created by former Meta employees Mo Shaikh and Avery Ching who were involved in the failed Diem blockchain project which wound down ​​in February of this year and sold its intellectual property and other assets.
The blockchain is built on a programming language originally developed for the defunct Meta-built Diem blockchain.

Commerce Ministry's Latest Export Controls Target 10 US Companies: Three Market-Moving Threads Explained

China's Ministry of Commerce placed 10 U.S. entities, including MP Materials, USA Rare Earth, Red Cat Holdings, and Teal Drones, on an export control list, banning the export of dual-use items. This move is seen as part of an ongoing countermeasure in the rare earth sector. The analysis suggests the primary impact is on U.S. companies within the **military, drone, and rare earth** sectors, aiming to restrict their access to critical Chinese materials and technology. For the Chinese market, the event is interpreted as reinforcing the **strategic value and pricing power** of domestic rare earth suppliers. However, the potential stock market reactions are nuanced: 1. **Chinese Rare Earth Upstream:** Companies like Northern Rare Earth are near yearly highs, indicating this event's "beneficiary" logic is largely priced in. It may confirm the trend but is unlikely to be a new major catalyst. 2. **Chinese Rare Earth Mid/Downstream & Drones:** Sectors like magnetic materials (e.g., Da Di Bear, Zhenghai Magnetic) and military drones (e.g., China Aerospace) are relatively undervalued. While the drone listing highlights sectoral competition, it doesn't directly translate to new orders for Chinese firms. 3. **Impact on Listed U.S. Companies:** The effect on stocks like MP Materials is ambiguous. While Chinese restrictions pose a challenge, these companies are also core to U.S. supply chain security efforts and may receive increased government support, potentially offsetting negative impacts. Their pre-announcement stock prices did not indicate panic selling. In summary, the export controls strengthen China's position in the global rare earth supply chain but have uneven effects across related stock market segments, with upstream Chinese gains likely priced in and downstream/drone sectors receiving more indirect, sentiment-driven attention. The outcome for the targeted U.S. stocks depends on the balance between restriction impacts and potential compensatory U.S. policy support.

Uniswap v4 Hook Analysis: Architecture Design, Common Vulnerabilities, and Protection Practices

Uniswap v4's Hook mechanism is a major innovation, enabling custom logic injection into liquidity pool lifecycle events like swaps and liquidity provisioning. This transforms the AMM into programmable infrastructure, shifting the security model from protocol-level to pool-level, as each pool's safety now depends on its bound Hook contract. The core architecture revolves around the singleton PoolManager contract, which manages all pools via a flash accounting system. State changes are tracked in transient storage and must be settled by the end of a transaction. Hook contracts are permanently bound to pools via a PoolKey, with their permissions encoded directly into their address via specific low-order bits. This design introduces unique security considerations and challenges for future upgrades. Key vulnerabilities and best practices identified include: - **Access Control Gaps:** Early versions of the BaseHook abstract contract only protect `unlockCallback()`, leaving other lifecycle functions (`beforeSwap`, `afterSwap`, etc.) exposed unless explicitly secured by developers. - **Unrestricted Pool Binding:** The `initialize()` function does not validate if a Hook "consents" to a new pool. Hooks must implement their own whitelisting in `beforeInitialize` to prevent unauthorized pool creation. - **Async/Custom Curve Hooks:** These high-risk Hooks can completely replace Uniswap's swap logic. Their security depends entirely on their own implementation, as they operate outside the native protocol's pricing safeguards. - **Delta Accounting Risks:** The system ensures final balance (NonzeroDeltaCount == 0) but cannot guarantee the *correctness* of intermediate delta states, which attackers could manipulate. - **Token Confusion:** Protocols must implement semantic validation for tokens in user-created markets, not just interface checks, to prevent cross-market confusion attacks. The article emphasizes that Hook auditing requires a "sub-protocol" approach due to extended interaction chains, highlighting a significant shift in security methodology for the v4 ecosystem.

Chips, Open-Source Models, and $50 Trillion: Joe Tsai Reassesses Alibaba Once Again

Alibaba Executive Chairman Joe Tsai recently outlined the company's comprehensive AI strategy in a public discussion. He believes AI represents a massive opportunity, estimating its potential economic impact at up to $50 trillion, stemming from the automation of human intelligence and productivity. Tsai detailed Alibaba's four-layer investment approach across the AI stack: starting from the chip level, moving to cloud infrastructure (Alibaba Cloud), then the model layer with its open-source Qwen model, and finally applications within its vast digital ecosystem (e-commerce, logistics, etc.). The company avoids the energy layer due to China's efficient infrastructure. This broad strategy is designed to ensure Alibaba captures value regardless of where it ultimately concentrates in the AI value chain. He dismissed concerns about an AI investment bubble, pointing to the enormous $50 trillion opportunity. While acknowledging U.S. cloud giants' higher capital expenditure, he argued Chinese firms, including Alibaba (funded by its cash-generative e-commerce core), need to invest more in AI infrastructure. A key theme was technological sovereignty. Tsai positioned open-source models like Qwen as a solution for companies, especially in Europe, seeking independence from proprietary U.S. models and greater data privacy control. He contrasted this with the trend of U.S. giants keeping their models closed-source. Tsai highlighted Alibaba's collaborations with European manufacturers like Bosch and Siemens, using AI for design and quality control. He concluded with an optimistic vision of AI agents enhancing productivity, ultimately freeing up human time for leisure, family, and experiences like live entertainment.
