The advisor BA Labs of the DeFi lending protocol Sky has proposed a plan to suspend new borrowings from the Core Vault. Data disclosed by BA Labs shows that there are currently 771 open vaults with a total debt of 376.33 million USDS.According to the proposal, borrowers can still make normal repayments and manage their collateral during the suspension period, but they will not be able to borrow new USDS. This adjustment targets new borrowing exposure, and existing positions will not be affected.

Coinbase's EU policy head Roeland Van der Stappen stated that the EU's efforts to tighten regulation on DeFi may push crypto users towards platforms with less investor protection. He told Cointelegraph that regulated crypto platforms might limit or even eliminate access to DeFi services as a result. He mentioned that rules aimed at protecting investors will ultimately push activities towards the least protected areas.In September, the European Securities and Markets Authority, in response to the EU Commission's MiCA consultation, suggested establishing a new category of regulated crypto services for companies providing access to DeFi protocols for customers. The European Banking Authority urged the Commission to explore new regulations for crypto lending that include suitability testing as one of the options. Van der Stappen noted that extending such tests to other DeFi services could treat simple stablecoin exchanges and leveraged lending equally, despite the different risks involved; lending, liquidity provision, and on-chain exchanges would be the most affected activities.He warned that restricting access through regulated platforms could fragment DeFi liquidity into smaller pools, resulting in worse trading prices for EU users and fostering isolated "walled garden" services that direct users towards providers outside the EU with less protection. An Adan-Ipsos survey in 2026 showed that 49% of French crypto buyers preferred accessing DeFi through exchanges, while 14% preferred personal wallets. Chainalysis reported that the slight decline in crypto activity in Germany was mainly due to reduced activity on decentralized exchanges; overall crypto activity in the EU grew by 2.2% in the 12 months leading up to June 2026.

A proposal by the U.S. Department of Labor to allow 401(k) retirement plans to allocate alternative assets such as cryptocurrencies has been submitted to the White House Office of Information and Regulatory Affairs for final review on Thursday. The proposal aims to simplify the process for retirement plans to offer alternative investments and provide certain legal protections for employers and plan administrators. The version released by the Department of Labor in March did not specify which digital assets could be included, nor did it set a minimum market capitalization threshold, but it requires administrators to assess six factors: performance, fees, liquidity, valuation, benchmarks, and complexity.Teresa Goody Guillén, managing partner of Bellementis PLLC, stated that Bitcoin and Ethereum may be adopted first due to their mature markets and investment products, but altcoins will not be automatically excluded; plan administrators must demonstrate that their investment choices meet standards of prudence, liquidity, valuation, and investor protection. Bernardo Brites, co-founder and CEO of Trace Finance, noted that some smaller tokens may struggle to meet historical performance and benchmark requirements. The proposal does not limit crypto investments to ETFs or managed funds, but Guillén expects such products may emerge before direct holdings.

Ethereum developer Marchhill submitted the draft EIP-8437, proposing to propagate proof wrapper data through the eth/73 protocol and introducing an optional mode that allows transactions to submit raw signatures to the aggregator without pre-generating STARK proofs.This proposal supports the direct propagation of certified packages with transactions and performs independent checks of specified programs in resource-constrained sandboxes to verify witness data. The new program does not require the development of native adapters for each signature scheme separately. Additionally, the proposal plans to limit the batch queue size, clean up expired transactions, and recheck records before formally generating proofs to support failure retries.Currently, the proposal is still in the Draft stage and has not yet been merged. The developer pointed out that VM and key binding consistency verification, cryptographic verification, and performance testing are still incomplete, and benchmarking has not yet been conducted.

Ethlabs published an article on the Ethereum developer community forum, proposing to set 2027 as the target year for Ethereum to achieve post-quantum and post-AI capabilities, referring to this plan as "pqai27." The proposal argues that with the rapid enhancement of AI capabilities, the accelerated development of quantum computing, and the increased ability of AI models to discover software vulnerabilities on a large scale, Ethereum should prioritize strengthening the security of its underlying protocol to prepare for potential future cryptographic risks and cyberattacks.Ethlabs pointed out that the U.S. government has advanced its target date for addressing quantum risks from 2035 to 2030, while Google plans to achieve post-quantum capabilities by 2029. At the same time, AI is solving a large number of long-standing mathematical problems and can also discover software vulnerabilities on a large scale. Ethlabs believes that although there is currently no evidence that existing cryptographic primitives will definitely be broken by AI, the associated risks are difficult to predict accurately, making it necessary to advance security upgrades proactively.In terms of the technical roadmap, Ethlabs divides the goals into two phases: the first is "pqai-ready," which means the Ethereum consensus layer will achieve a post-quantum upgrade, allowing all users to have a path to migrate to post-quantum accounts; if existing cryptography fails prematurely, the network can still operate with reduced processing capacity. The second is "pqai-scaled," which means supporting post-quantum transactions and data availability under full network capacity, aiming for post-quantum transactions to reach the processing scale of ordinary transactions, including post-quantum signature aggregation and post-quantum data availability solutions.To achieve this goal, Ethlabs suggests reassessing the scope of the upcoming hard fork Hegotá, reconsidering upgrades that do not belong to the critical path of pqai27. Among them, Frames and related post-quantum account proposals are still regarded as key components; FOCIL needs to be reassessed for its impact on upgrade progress and post-quantum compatibility. Additionally, Ethereum needs to choose between the post-quantum transformation of the existing Gasper consensus protocol and transitioning to a decoupled consensus. Ethlabs stated that to concentrate resources on advancing pqai27, it will withdraw the Quick Slots feature previously sought for Hegotá and plans to continue promoting this feature in 2028. The Glamsterdam upgrade and its scaling plan will proceed as originally scheduled. This roadmap remains a suggestion proposed by Ethlabs and will require further discussion and determination by Ethereum core developers.

The public chain Sei announced that the SIP-6 proposal has been approved, and the development team Sei Labs will initiate the Autobahn consensus upgrade. This is a core part of the Sei Giga upgrade, which will change the mechanism of a single validator proposing blocks to multiple validators proposing transaction batches in parallel.This adjustment aims to enhance the network's ability to process order placements, order cancellations, and price updates. Sei's previously announced performance targets are to handle 200,000 transactions per second and achieve final confirmation in about 250 milliseconds. The announcement did not disclose the mainnet activation time.

LlamaRisk proposed a gradual exit from the Aave V3 Core portion of collateral, involving approximately 1.33 billion dollars in assets and its supported 1.03 billion dollars in debt.

The XRP Ledger Foundation's 2027 roadmap outlines the anti-quantum signature amendment, planning to first study migration solutions, and then advance development and auditing.

Zcash community member ValarDragon posted on the official community forum, proposing a series of plans to be included in the NU8 network upgrade, and suggested setting the upgrade target for the end of January 2027. The main content includes the launch of the Tachyon shielded pool, expanding transaction formats, increasing the maximum block size from 2MB to 8MB, and adding support for post-quantum cryptography transparent transaction opcodes.Other proposals also include: adjusting the NSM redistribution date to be closer to the time of Zcash's seventh halving; determining a date at the protocol level for Sapling to stop accepting new deposits while continuing to support transactions and withdrawals; and eliminating the need to update the Consensus Branch ID with each network upgrade to reduce wallet compatibility issues. ValarDragon stated that with the combination of Tachyon and larger block capacity, a shielded transaction processing capability of approximately 200 TPS is expected. In addition, the post-quantum transparent transaction feature will introduce schemes based on SPHINCS with 128-bit and 192-bit security levels. The above content currently belongs to the upgrade ideas proposed by community members, and specific implementation still depends on development progress and subsequent NU8 discussions and voting.

According to reports from Saudi Arabia's Al Arabiya television, sources revealed that the Iraqi Prime Minister proposed suggestions to end the war with Iran during a phone conversation with U.S. President Trump. Trump expressed agreement with the suggestions made by the Iraqi Prime Minister during the phone call.Trump asked the Iraqi Prime Minister to play a mediating role on the issue of Iran and requested that the Iraqi Prime Minister convey relevant suggestions aimed at ending the war to Tehran.

Hyperscale Data plans to repurchase up to $50 million of common stock at a price of $2 in cash plus 1 share of 12% preferred stock for every 100 shares, representing an 82% premium over the closing price on November 6.

The New Zealand FMA plans to exclude eligible New Zealand dollar-backed stablecoins from the classification of financial products, with the consultation closing on December 18.

According to CoinDesk, Solana developers have proposed to abolish the persistent nonce transaction feature, which was used in the April attack on the trading protocol Drift, resulting in a loss of at least $270 million. The proposal still requires technical approval and is expected to take effect on the mainnet as early as May 5, 2027.Persistent nonce allows signed transactions to remain valid for a long time, enabling custodians and exchanges to perform offline signing. Relevant institutions will need to migrate to alternative solutions, and the migration requirements from the Solana Foundation may delay the final deadline.

Zcash developers proposed to shorten the blockchain target block interval from 25 seconds to 20 seconds to accelerate transaction confirmation speed. On Sunday, developers ValarDragon and Evan Forbes submitted a draft of a Zcash Improvement Proposal (ZIP) to the Zcash community forum, hoping that this change will be included in the next community vote and considered in the upcoming NU7.1 network upgrade.According to the proposal, shortening the block interval will reduce the expected waiting time for the first transaction confirmation, thereby improving the user experience for offline payments, exchange deposits, and cross-chain swaps. The developers stated that this change will not increase the overall processing capacity for daily privacy transactions on the network; at the same time, despite more frequent block generation, the proposal will maintain Zcash's existing issuance schedule.The proposal was made a few days after the NU7 upgrade went live. On Friday, the NU7 upgrade activated on the mainnet, shortening the network target block interval from 75 seconds to 25 seconds. This upgrade also introduced a network sustainability mechanism, using part of the transaction fees collected for future mining rewards while maintaining Zcash's supply cap of 21 million ZEC.

The Financial Services Commission of South Korea is coordinating inter-departmental differences on the government draft of the "Basic Law on Digital Assets," aiming to present it in November and is expected to advance it in the form of legislative action by lawmakers. Regulatory authorities are discussing setting a single shareholder ownership limit for cryptocurrency trading platforms at 15% to 20%, and providing existing platforms with a transition period of 1 to 2 years; considering property rights disputes, it may also change to only restrict voting rights.The bill proposes to change the access to trading platforms from a declaration system to a licensing system, with stablecoin issuers expected to adopt a bank-centered consortium model. Discussions are also underway regarding implementing strict liability for hacking attacks and system incidents, as well as listing violations of actual holding obligations for crypto assets as grounds for suspension of operations. On November 5, South Korea's Deputy Prime Minister and Minister of Economy and Finance, Lee Hyeong-ik, stated that he would consult with the National Assembly to postpone the implementation of the cryptocurrency asset income tax originally scheduled for next year by two years. The ruling party advocates prioritizing the formulation of this law, establishing an overall regulatory framework, and allowing a transition period for businesses and investors.

The U.S. Treasury and the Federal Reserve have withdrawn a previously proposed rule draft that aimed to lower the threshold for the "Travel Rule" regarding cross-border fund transfers from $3,000 to $250. After the withdrawal, the $3,000 threshold continues to apply, including for eligible cryptocurrency transfers under current FinCEN guidelines.The proposal was jointly issued by FinCEN and the Federal Reserve in 2020 and applies to fund transfers and remittances that originate or terminate outside the United States, while the domestic transaction threshold remains unchanged at $3,000. The proposal also clarifies that the relevant rules apply to convertible virtual currency transactions and digital assets with legal tender status, and requires financial institutions to collect, retain, and transmit specific transaction information as mandated.

According to a report by the Russian news agency TASS, the Russian Investigative Committee has proposed further incorporating cryptocurrency assets into the anti-money laundering regulatory system and strengthening the tracking of cryptocurrency transactions. At the meeting of the United Nations Convention against Corruption's Intergovernmental Working Group on Asset Recovery held in Vienna, Austria, the committee representative Anna Starzhinskaya stated that investigators can currently track cryptocurrency transactions through a dedicated system of the Federal Financial Monitoring Service of the Russian Federation (Rosfinmonitoring) and obtain important evidence for criminal investigations.The Russian Investigative Committee also emphasized the importance of cross-border crime investigations and international judicial cooperation. The agency disclosed that by 2026, it had jointly seized and confiscated corruption-related assets worth over $486 million in collaboration with financial intelligence and law enforcement agencies, and had made approximately 2,500 information inquiries to financial monitoring departments in criminal cases.

According to Fields' concept, an attacker stealing 1 BTC needs to provide an additional 1 BTC from a quantum-safe wallet as collateral, and both funds will be locked for a waiting period, such as 30 days.Before quantum attacks become a reality, the original owner can create a quantum-safe "mine" that contains hidden proof of ownership. If the thief later attempts to transfer the vulnerable coins, the stolen BTC and the thief's collateral will be locked. The owner can disclose the proof during the waiting period to reclaim their BTC and receive the thief's collateral as a penalty. The thief cannot determine which addresses have traps before investing funds.

According to CryptoBriefing, the Dubai International Financial Centre (DIFC) Court released a white paper on "Dispute Resolution Oracles" (DRO) on November 5, proposing a scheme that allows off-chain court or arbitration decisions to directly trigger the enforcement of on-chain tokenized assets. This mechanism is entirely based on the principle of voluntariness, requiring parties to designate a dispute resolution forum in advance, with the DIFC Court serving as the first qualified provider.The DRO itself does not actively change assets but is responsible for verifying execution instructions and generating auditable execution records on the participating blockchain; actual dispute resolutions, arbitration, and mediation will still proceed in the traditional manner. The white paper positions this framework as an open technology and legal standard and outlines five core elements: jurisdictions with enforcement capabilities, adoptable open standards, a qualified provider registry, a controlled pilot program, and international dialogue on mutual recognition.The proposal was announced at the Dubai Future Tokenization Forum and is part of the DIFC Court's growth strategy from 2026 to 2030.

The proposal from the U.S. SEC regarding amendments to the financial responsibility, recordkeeping, and reporting rules for cryptocurrency asset brokers has been submitted for review by the White House.
