Ethereum co-founder Vitalik Buterin announced today that the original novel "Snowmoon" has been completed, consisting of 32 chapters.The novel unfolds in a speculative science fiction setting, depicting a world that heavily relies on cryptography and decentralized governance. The story focuses on the ideological conflicts between societies such as Veridia and the Arctic Empire, involving elements like zero-knowledge proofs, second voting, privacy technologies, and content-oriented tax mechanisms, integrating themes of mechanism design and digital sovereignty that have long been of interest to Vitalik.The work is released under the GPL v3 license. Vitalik stated that adaptations into films, animations, and other derivative works are allowed, but requires the related production pipeline (including AI prompts, scripts, and other non-generic materials) to be open-sourced. He declared that all text was written by him, with AI assistance only used for spelling and grammar checks, consistency verification, and webpage formatting, and noted "Snowmoon was written with love."

Hester Peirce, a commissioner of the U.S. Securities and Exchange Commission (SEC), stated at the SIFMA Digital Assets Conference that regulators should reconsider traditional financial monitoring methods, shifting from "collecting more data" to utilizing new technologies for more precise verification.Peirce mentioned that technologies like zero-knowledge proofs can verify whether users meet requirements such as age, citizenship, accredited investor status, or sanctions lists without disclosing underlying personal information like names, income, or addresses.Hester Peirce suggested that the federal government and regulatory agencies adopt attribute-based verification when technically feasible and allow registered entities to rely more on third-party identity verification to reduce the redundant collection and storage of sensitive information.Peirce also stated that public blockchains have permanent, public, and auditable transaction records, and combined with blockchain forensic tools, they are expected to enhance the ability to track illegal activities while reducing unnecessary data collection.

TypeSafe AI announced that Jev is officially open to everyone, removing the waiting list. Users can now directly register and use the official Console without needing to apply for Early Access.Jev does not handle chatting or writing code; it only performs classification, scoring, and judgment. Developers provide candidate options in advance, and it directly returns selections, probabilities, and confidence levels, allowing the program to continue execution with the results. Currently, the official price remains at $0.042 per million input tokens, with output being free.Before the opening, Jev had rapidly spread on third-party platforms. Vercel stated that within 24 hours of integrating the AI Gateway, it was used by nearly 13% of paid teams, becoming the fastest adopted new model in the history of AI Gateway, with an adoption rate more than double that of the GPT-5.6 series during the same period.

According to X user @UngusTrade's post on September 21, a commit named "Binary options support" recently appeared in Lighter's prover code repository, which describes ZK circuits that support Lighter. The code shows that this implementation is for standard binary outcome contracts, with a settlement cap for each market, typically set at 100 for prediction markets, where share prices trade between 0 and the cap, settling at either 0 or the cap. The contracts are fully collateralized in USDC, with no leverage and no liquidation.It is noteworthy that the circuit supports continuous markets, allowing for settlement at any value within a range, thus enabling contracts based on measurements, rather than just yes or no events. Additionally, Lighter may allow whitelisted operators to create, manage, and settle markets, similar to the deployment model of HIP-3. Currently, Lighter has not commented on this.

A Bitcoin wallet created on November 2, 2011, transferred 100 BTC at a block height of 967732, valued at over 8 million dollars based on the price at that time. The wallet purchased Bitcoin at a price of 3.24 dollars, with a cost of approximately 324 dollars for 100 BTC, resulting in an unrealized return of about 2,469%.On the same day, four wallets created between February and March 2013 transferred 25 BTC each, totaling 100 BTC, into the cryptocurrency custody company BitGo wallet. On-chain characteristics indicate that this batch of Bitcoin originally came from block rewards in March 2013; the miner has been continuously transferring similar amounts of BTC to BitGo in batches since August 2025. The two transfers totaled 200 BTC, currently valued at over 16 million dollars.The new address of the 2011 wallet is a P2WPKH address, which has not been marked by major block explorers as an over-the-counter trader or centralized exchange address; whether the funds transferred by the 2013 miner to BitGo have been sold cannot be confirmed by on-chain information.

Bankless co-founder David Hoffman posted on the X platform, stating, "We have now entered the altcoin season, and the real market moment has arrived earlier than expected." David Hoffman announced on May 21 that he had liquidated his ETH holdings and subsequently bought VVV, NEAR, ZEC, HYPE, and LIT, all of which have significantly outperformed ETH.

According to Bitcoin Magazine, Matthew Sigel, the head of digital asset research at asset management company VanEck, stated in an interview with CNBC that quantum computing poses a risk to Bitcoin, but the community has recognized the seriousness of the issue. He pointed out that due to the decentralized nature of the crypto network, progress in addressing this issue may be slow, but the community is advancing related work.Sigel said, "This is a risk, but the community has already recognized the scope of the problem, and a large number of talents have gathered and proposed a framework for upgrading the system." He added, "Upgrades will not happen quickly because no CEO can tell developers 'do it now.' The governance process takes more time, and the process is more complex, but there are technical paths to achieve quantum resistance, and you will see more related progress in the coming years."Currently, quantum computers still have error rate issues and cannot crack Bitcoin's encryption algorithms. Some Bitcoin developers have begun testing quantum-resistant signatures on real-time sidechains. Coinbase plans to build a post-quantum signature pipeline using secure enclaves and threshold cryptography, and the Bitcoin Security Alliance, composed of BlackRock, Fidelity Digital Assets, Block, and others, is also supporting proposals like BIP-360 to reduce long-term quantum computing risks.

According to Bitcoin Magazine, renowned financial advisor and founder of Edelman Financial Engines, Ric Edelman, stated on Bitcoin Magazine TV that buying Bitcoin now is like buying Amazon in 1999, and he predicts that the price of this leading cryptocurrency will reach at least $500,000 before 2030.Edelman noted that in 1999, people were still debating whether to invest in Amazon, but now there is no debate, and everyone owns it. He believes Bitcoin will follow the same trajectory in the future. He also mentioned that if everyone in the world allocated 1% of their assets to Bitcoin, the corresponding price would be $500,000, and he claims his prediction is actually conservative, as the final price could exceed $500,000 and the timeline could be earlier than 2030.Edelman is a long-time Bitcoin advocate, and he revealed that when he introduced Bitcoin to his peers in the financial services industry in 2013, he was often booed off stage. Today, most people in traditional finance at least acknowledge that the asset "has established a foothold." The article also mentioned that Bitcoin's recent price is about $76,522, up 1% in the past 24 hours, achieving its best performance in years in August, but still far below the historical high of $126,080 set in October.

Cryptocurrency analyst Willy Woo stated, "I personally believe the probability of the cryptocurrency market hitting the bottom is 90%. Based on the liquidity of long-term investors returning, we are currently in an early bull market structure. The core of the judgment is the liquidity structure of BTC; there is an intention to avoid historical cyclical patterns, although these cyclical patterns have performed exceptionally well in determining market bottoms so far. According to cyclical patterns, the consensus probability among other analysts is about 40%.From the perspective of liquidity structure, we are currently in an early bull market, and the market bottom has likely already occurred. If this judgment is correct, then there is another question: how long will this bull market last? Will it last for 3 years? I wouldn't necessarily bet on that, as historical cyclical patterns are gradually losing effectiveness. As long as the inflow of investor funds does not show significant weakness, the bull market structure will continue, but the duration is currently uncertain."

According to MTS, there are rumors that several leading AI laboratories have used models to provide solutions to multiple long-standing major mathematical problems. However, following the controversy surrounding the results related to Navier-Stokes, these institutions have chosen to temporarily withhold the publication of relevant results.
