Robinhood CEO Responds to AMC's Criticism: Publicly Listed Companies Cannot Control Financial Products Created Around Their Stocks

US President Donald Trump’s second son Eric Trump reposted a post about the meme coin LAPTOP’s sharp price crash after its launch, commenting: “Hunter should go back to painting.” His remarks target Hunter Biden, son of former US President Joe Biden, who launched the meme coin LAPTOP. The reposted post notes that LAPTOP plummeted 98% within minutes of going live, adding that the project had originally planned to allocate a portion of its tokens to users who incurred losses from TRUMP-related transactions.

Solana ecosystem full on-chain prediction market World announced that its independent platform World.xyz has officially launched, with over 1 million users on its waitlist. The platform offers thousands of markets spanning sports, cryptocurrency, politics, finance, economics, and culture, covering all NFL regular seasons, 7 soccer leagues, F1 races, the 2026 U.S. midterm elections, and Federal Reserve interest rate decisions. Since integrating Phantom in July, World has launched more than 150,000 markets. Each market on the platform consists of "Yes" and "No" contracts, priced between $0 and $1, and settled using Phantom’s U.S. dollar stablecoin CASH. Technically, World leverages Chainlink Data Streams and Chainlink Runtime Environment to provide market data and automated settlements, reducing manual intervention and dispute resolution wait times. Prediction markets for stock price movements, gold, silver, oil, natural gas, computing power, and weather will be rolled out sequentially.

Bubblemaps posted that profit and loss data for LAPTOP traders shows roughly 80% of participants are in the red, describing the token’s market performance as a "bloodbath". Specifically, two traders lost between $100,000 and $1 million, 100 lost over $10,000, 700 lost more than $1,000, and around 11,000 traders posted small losses. Bubblemaps did not further disclose the statistics’ time frame or the scope of the wallet sample used.

a16z Crypto has announced the release of a new version of its open-source zero-knowledge virtual machine (zkVM), Lattice Jolt. The update switches the underlying cryptography from elliptic curves to lattice cryptography, making the system quantum-resistant, and boosts both prover and verifier speeds by 2 to 3 times. Its proof size currently stands at under 100KB, which a16z Crypto claims is the smallest proof of any post-quantum zkVM. Lattice Jolt uses a novel polynomial commitment scheme called Akita, built on the Module-SIS lattice hardness assumption, with a target 128-bit security level. Akita was developed by LayerZero’s research and engineering team in collaboration with teams from Carnegie Mellon University, the University of Southern California, and a16z Crypto. Performance-wise, Lattice Jolt can prove over 2 million RISC-V cycles per second on a CPU-only device; with Apple Metal GPU acceleration, it exceeds 10 million cycles on a MacBook. The prover’s memory footprint has also dropped from roughly 300 bytes per cycle to 200 bytes, supporting proof generation for millions of compute cycles on mobile phones. The project will add additional zero-knowledge functionality via an upcoming academic paper.

Ethereum co-founder Vitalik Buterin has published a post detailing the recursive STARK mempool proposal EIP-8288, which he aims to include in Ethereum’s I-star upgrade following the Hegota upgrade. The proposal cuts on-chain computation and data costs by offloading signatures and proofs from Ethereum’s core execution path and recursively aggregating STARKs within the mempool. Vitalik noted that the solution supports low-cost quantum-secure signatures and privacy protocols, with the cost of quantum-secure private transactions projected to drop from around 10 million Gas to tens of thousands of Gas. It is also compatible with new signature or proof schemes such as Falcon and ML-DSA without modifying the EVM, while enabling private account abstraction. Per the design, nodes will periodically aggregate transaction dependencies and generate recursive STARKs, and block builders will produce proofs for transactions slated for inclusion in blocks. Each block’s additional on-chain overhead is approximately a 100–300 KB STARK, plus 96 bytes of data per statement to be proven. The scheme may also drive Ethereum to adopt RISC-V as the standard instruction set for recursive STARKs.

According to market data from BIT (bit.com), the three major US stock indexes declined, the yield on the 10-year US Treasury note rose above 4.85%, the yield on the 30-year US Treasury bond broke through 5.30%, the US Dollar Index surged sharply, and spot gold fell rapidly. On the news front, the US Treasury Department announced it would repurchase up to $6 billion in long-term bonds on Thursday. Previously, the US Treasury had stated that the size of each single long-term bond repurchase would at least double to $4 billion before November 4.
