The Zcash development team plans to add post-quantum signature support to the network in January. Zakura engineer Roman Akhtariev stated in an engineering blog that the team plans to implement post-quantum signature opcodes in Zcash in January. These opcodes will enable Zcash to verify hash-based signatures, thereby resisting quantum computing attacks. The team has not yet confirmed a specific network activation date. This upgrade aims to prevent attackers from using current public keys to reverse-engineer and forge payment authorizations from wallet owners.The initial phase of this upgrade will protect transparent transactions. Zcash has two payment methods: shielded payments hide the sender, receiver, and amount; transparent payments are similar to Bitcoin, where addresses and amounts are visible on the chain. According to CoinDesk, based on ZecStats data, approximately 11.96 million of the 16.98 million issued ZEC are stored in the transparent pool, accounting for about 70%. The January plan primarily targets this public portion. Additionally, Zakura has developed a private query tool that allows wallets to check balances without exposing associated addresses to the server; the experimental version is available in the "Private queries" settings of the Zcash wallet Vizor.Before the release of Zakura's engineering article, Ethereum researcher Justin Drake warned holders on Thursday to prepare for what he called "bunker mode," stating that in the worst-case scenario, AI could find shortcuts to break the mathematical protections of Bitcoin and Ethereum wallets in "months rather than years."

CryptoQuant analyst Darkfost stated that the cryptocurrency market has recently entered a short-term correction phase, with the total market capitalization of altcoins (Total2) shrinking by over $11 billion in just three days, excluding Bitcoin; among them, Ethereum (ETH) saw a decline of 11%, with a market cap reduction of over $38 billion.Despite the price correction, investors continue to accumulate and withdraw Ethereum. During this period, the Ethereum reserves on the Binance exchange decreased from 3.57 million to 3.47 million, reaching the lowest level in six months; compared to the reserve of 3.92 million in August, this represents a decline of nearly 11.5%. Meanwhile, the withdrawal trading activity on the Binance platform has significantly increased, with over 320,000 Ethereum withdrawal transactions recorded on October 6, setting a new historical high.

On October 8, 2026, the Spanish government approved Royal Decree No. 813/2026, tightening anti-money laundering regulations.

According to data from Delphi Digital, NEAR launched NEAR Intents, achieving the highest transaction fee revenue of the year in September.Previously, NEAR set the perpetual contracts of the high-performance decentralized derivatives trading platform Hyperliquid to privacy mode by default. Users can deposit funds from other chains and participate in trading through token swaps on NEAR Intents. After the privacy feature went live, users tended to retain their funds during trading intervals, with their confidential balance exceeding 70 million dollars on the first day of launch. Delphi Digital stated that this could be an early signal of market demand converting into actual usage rates.

Illia Polosukhin, co-founder of NEAR, stated that recently the activity of developers within the ecosystem has increased and the development threshold has further lowered, focusing on what kind of applications to build and how to establish distribution channels.In this regard, he proposed a series of potential construction directions, covering AI electronic pets that combine NEAR AI on-chain verifiable reasoning with non-fungible tokens (NFTs), a universal checkout component that supports full-chain intent payments, a decentralized encyclopedia that combines prediction markets with AI-generated content, a privacy off-chain trading (OTC) market based on NEAR Intents and management of anti-liquidation lending and perpetual contracts, a cross-chain activity registration custody tool in the form of a staking deposit, privacy code review agents, enterprise equity structure management tools, Delta neutral strategy management, privacy tracking single transactions based on view keys, end-to-end encrypted medical auxiliary diagnostic systems, privacy voice transcription desktop applications, and AI benchmarking based on private test sets.Regarding product distribution, he suggested combining NEARLegion with community channels like X, achieving multi-chain wallet compatibility through Aurora Intent Connect to lower cross-chain thresholds, and actively expanding across communities and platforms like Product Hunt.

On-chain data analysis firm Bitquery linked the approximately $459,000 asset theft incident involving Tradewiz to a wallet that completed 27 transactions through the trading bot previously. Investigation statistics show that the incident affected 20,933 wallets, with losses involving SOL, tokens, and deposits recovered after closing token accounts; the valuation is based on a SOL price of $120.Bitquery discovered that major fund transfers began 41 minutes after Tradewiz's trading activity stopped; about 73% of the SOL in this round of transfers was moved afterward. Tradewiz stated that the incident involved the private key leak of the SOL PVP export function and promised to compensate users for their losses; subsequent updates indicated that the first batch of refunds had been issued, and claims need to be verified. Tradewiz also suspended EVM services for security checks and stated that the police are assisting in tracking the assets and have contacted exchanges for identity and account verification information.Bitquery traced some of the early funds coming from MEXC withdrawals, later shifting to Kucoin deposit addresses; these connections do not indicate that the two exchanges participated in the theft.

The Illinois Department of Revenue has released the legislative draft details of a 0.2% digital asset transaction tax, clarifying that stablecoins will be considered taxable digital assets, while non-fungible tokens are not subject to taxation. The draft stipulates that DeFi transactions are generally exempt; however, fees paid by users that are deemed "valuable consideration," such as protocol fees for operating or maintaining the platform, may trigger taxation.Only network fees and exchange fees paid to liquidity providers do not trigger this tax. Cross-chain bridging conducted through digital asset brokers and paid with consideration will be regarded as taxable exchange activities. If centralized exchanges charge fees when transferring to self-custody wallets, it may also be subject to taxation. This tax law was approved in June and is set to take effect on January 1, 2027. The Illinois Department of Revenue is seeking public comments on the draft, with a deadline of October 30.

According to Cointelegraph, the European Central Bank (ECB) has announced the launch of a new round of applications for the digital euro innovation platform, inviting fintech companies, payment institutions, and other organizations to explore AI agents participating in digital euro payments.The project will be divided into two parts: practical testing and future application seminars. The practical testing will take place from January to June 2027, where participants will develop prototypes for electronic receipts, multi-party transactions, conditional payments, and more.The seminars will explore AI payments, micropayments, machine-to-machine transactions, and the application of the digital euro in public services. In addition, the ECB has selected 36 banks and payment institutions, including Revolut, Stripe, and Deutsche Bank, to participate in another 12-month digital euro pilot, which is scheduled to launch in the second half of 2027. The final issuance of the digital euro still requires EU legislation and subsequent decisions from the ECB.

Co-founder and Chief Operating Officer of the cross-chain trading platform Relay, Jason Maier, stated that the team discovered an issue with the Relay API over the weekend, which exposed pending transaction information before trade execution. MEV seekers exploited the pending routing status to infer on-chain paths and front-run trades before order execution, resulting in worse execution prices for users trading through Relay.This activity occurred from September 12 to September 26, primarily concentrated from September 23 to 26. Seekers profited approximately $136,000 from this, affecting around 5,600 users, with a median impact of $11.88. Relay will pay a $50,000 bounty to Outputlayer for reporting the issue and will automatically compensate affected users without the need for applications; funds will be directly sent to wallets, with a total compensation amount of approximately $312,000.Jason Maier stated that MEV can arise through public mempool exposure, order detail inference, malicious participation in auctions, or data gaps between service providers, and protecting a single link in the transaction path is not sufficient. He mentioned that the team will continue to enhance the execution quality and privacy of the entire transaction path and called on security researchers to report vulnerabilities when discovered.
