Citibank stated in its official insights report "Digital Frontier: Collateral in a Tokenized World" that as financial markets accelerate towards continuous, around-the-clock operations, collateral management is undergoing a structural evolution. Institutional-level tokenization is moving beyond isolated proof of concepts to establish scalable operational tracks on global banking, custody, and market infrastructure, making collateral a continuous liquidity and optimization engine.Citibank mentioned that combining tokenized assets with regulated on-chain settlement currencies can achieve instant atomic cash-to-cash transactions, eliminating multi-day gap risks and expanding the range of eligible collateral to include tools like tokenized money market funds. Global asset managers and asset owners will unify traditional and digital collateral into a single, continuously optimized inventory over many years of hybrid operating models, covering counterparties, custodians, and settlement venues.

Vitalik posted on the X platform to congratulate the @zksync Airbender team for achieving this milestone. He believes that the speed competition of zkEVMs has achieved a decisive victory, and the primary focus should shift entirely to security.Vitalik stated that this means there is a need to formally verify the equivalence of arithmetic and Ethereum specifications, the hard upper limit of the ratio of prover costs to total block Gas, and the security of the proof system itself.

According to Bloomberg, data shows that the total open interest of perpetual contracts on mainstream trading platforms has decreased from $81 billion to about $67 billion over the past year, while the open interest of contracts linked to real-world assets (RWA) has increased from nearly zero to $9 billion, accounting for 14% of the total. This indicates that the enthusiasm for leveraged trading in the crypto market has not yet returned to previous levels, and the related trading infrastructure is gradually expanding to traditional assets such as stocks and commodities.During the same period, the open interest of Bitcoin perpetual contracts decreased by about $8 billion, Ethereum by about $5 billion, and other tokens collectively decreased by about $10 billion, with the growth of traditional asset contracts only partially offsetting the aforementioned declines.

Recently, the Polkadot community submitted a proposal named DOT DAO Strategy Mandate on the SubSquare platform, advocating for a shift in the DAO's strategic focus from previous ecological scale expansion and locked asset growth to acquiring end users and real usage scenarios, and plans to build a user-oriented Polkadot Product Platform.Another core aspect of the proposal is the introduction of permissionless DOT collateralized stable assets called dotStables, with a priority support for dotUSD. This asset adopts a collateral model similar to Liquity, aiming to ultimately convert stablecoin demand into demand for DOT.In terms of platform design, it will be compatible with existing parachain infrastructure and emphasize user experiences such as Freemium model, mobile-first, self-custody, privacy protection, and no-login features. Currently, the proposal is still in the governance preparation stage.

Digital Asset co-founder and CEO Yuval Rooz stated at the Token2049 conference in Singapore that the crypto industry should leverage the current regulatory environment to accelerate institutional adoption, believing that the widespread use of blockchain will make it harder for future governments to reverse industry progress. He compared this opportunity to Uber and Airbnb, stating that both companies had established themselves before policymakers effectively restricted them, saying, "By the time people react and decide to legislate against these companies, it will be too late."Rooz indicated that the industry should ensure blockchain is widely used so that no matter what happens in 2028, "there is no turning back." The next U.S. presidential election is scheduled for November 7, 2028, which may bring changes in government and regulatory priorities. This statement comes in the context of the CLARITY Act failing to advance in the Senate procedural vote in September, while the U.S. Securities and Exchange Commission (SEC) and the Commodity Futures Trading Commission (CFTC) have been advancing crypto regulation based on existing authority.In the same Token2049 panel discussion, Binance co-CEO Richard Teng expressed hope that the CLARITY Act could still become law, believing that legislation could prevent regulatory backtracking and encourage institutional entry, calling the possibility of reversing current progress the industry's "greatest fear." Franklin Templeton CEO Jenny Johnson stated that legislation would provide greater certainty, but the industry should not rely on the passage of the CLARITY Act, as the SEC and CFTC are already working to provide regulatory clarity to sustain innovation and institutional adoption.

ChainCatcher live report, at the OKX NOW Global Product and Ecosystem Conference (Singapore), Ethereum co-founder Vitalik Buterin stated that AI has demonstrated strong penetration and offensive and defensive capabilities, with cases emerging of breaking out of sandboxes, attacking websites, and discovering various software vulnerabilities and exploits. "Anything with vulnerabilities will eventually be discovered by AI; GPT-7, Claude 7, DeepSeek 7 will find it."At the same time, AI is also helping the Ethereum protocol discover bugs, implement complex cryptography, and perform formal verification at both the protocol and application layers. Vitalik believes that higher security levels will shift from "optional" to "mandatory," and the industry is in a fascinating yet challenging transitional period.

According to The Wall Street Journal, Michael S. Selig, chairman of the U.S. Commodity Futures Trading Commission (CFTC), announced on October 5 that the CFTC has officially proposed the first batch of regulatory rules for the cryptocurrency market, aimed at promoting innovation and protecting investors.Previously, due to Congress's failure to pass relevant bills clarifying the federal legal status of cryptocurrency assets, the CFTC and SEC turned to existing statutory powers to lead the formulation of market structure rules. During the previous administration, the two regulatory agencies primarily targeted cryptocurrency exchanges, custodians, and software developers through enforcement actions, resulting in a large number of cryptocurrency companies moving overseas.The introduction of the new rules marks an important shift in U.S. federal cryptocurrency regulation from "enforcement instead of legislation" to "proactive rule-making."

Bybit CEO Ben Zhou stated in an interview with Turkish media Fintechtime that, reflecting on the 2025 Bybit attack incident, one of the issues was the use of third-party service providers and the excessive concentration of assets within that third-party related system.Zhou mentioned that since then, Bybit has comprehensively adjusted its security policies, shifting to a zero-trust model, while decentralizing wallets across different architectures and strengthening the isolation of local and global operations to reduce the risk of a single attack impacting a large amount of assets. He also stated that Bybit hopes to develop its Turkish operations into a super application covering crypto trading, payments, global transfers, and more investment products in the future.

CryptoQuant analyst Darkfost stated that the cost basis of short-term holders (STH) of Bitcoin has confirmed a crossover above the cost basis of active long-term holders (LTH), indicating a shift in market momentum. Based on this, he judges that the Bitcoin bull market has been confirmed. This is the 5th occurrence of this signal in history, but he emphasized that there is still a possibility of misjudgment regarding the relevant indicators."Active LTH" is defined as long-term held supply that has moved at least once in the past 7 years, to exclude long-term dormant or illiquid BTC. Currently, over 3.5 million BTC that have been held for more than 10 years remain dormant, with this portion of supply increasing by an average of about 8,000 to 30,000 BTC per month. Since 2019, this indicator has only shown negative growth once, due to an early miner reactivating and transferring about 100,000 BTC, which is considered a relatively isolated event. Darkfost believes that this signal currently reflects positive changes in the Bitcoin market, with ETF liquidity inflows being one of the driving factors.

DeFi researcher Ignas stated that the popularity of Robinhood's ecosystem tokenized stocks and Meme coins is waning, with the TVL of Robinhood Chain's tokenized stocks remaining flat for two consecutive weeks, and the number of stocks destroyed has exceeded the issuance amount.Ignas further indicated that if trading volume continues to slow down, a decline in revenue may lead to weakened holding willingness, increased selling pressure, and cause LPs to exit, resulting in further liquidity contraction. He revealed that he has exited the Meme coin LP position due to a significant drop in yields and believes the market needs new catalysts to drive the trend again. He also noted that tokenized stocks on Solana seem to still be rising and speculated that the trend of funds shifting from Robinhood to Solana may be more sustainable.
