Zcash full node developer Zakura has proposed “one-time” viewing keys to stop a future quantum computer from linking a user's shielded Zcash payments. The biggest risk is swaps through NEAR Intents, where each swap out of ZEC posts one of the user's shielded addresses to NEAR's public chain as a refund address, and around $600 million to $700 million had flowed through that route by May, according to Zcash Open Development Lab CEO Josh Swihart. The fix derives a separate incoming viewing key for each published address while leaving the spending key untouched, so a quantum attacker who breaks one address would only see payments to that address. The approach needs no network upgrade, and wallets built on Zakura's open-source libraries, such as Vizor, can add it in the coming weeks, with hardware wallets to follow. At the time of reporting, ZEC traded at $1,165, up 3.6% on the day.

- Zcash developers plan a fix to keep ZEC swaps private from future quantum computers
The team behind Zakura, a newer version of the software that runs the Zcash network, proposes giving every ZEC swap made through NEAR Intents its own viewing key. This would stop a refund address posted on NEAR's public chain from exposing a user's wider payment history to a future quantum computer. Spending keys would stay with users, and private information retrieval would let wallets locate refunds without revealing which addresses they are checking. Zakura says compatible wallets could adopt the feature within weeks, ahead of Zcash developers' January target for quantum-resistant payments. No quantum computer capable of recovering these keys has yet been demonstrated.
- Live updates: Bitcoin back above $82,000, ZEC jumps 11% as ETF outflows continue
Bitcoin climbed back above $82,000 on Friday after briefly dropping under $80,000 the day before, as ZEC led a broad crypto rebound with an 11% jump to about $1,230. The rally did not extend to ETFs: the U.S. spot ZEC fund lost about $15 million on Thursday, its fifth outflow this month, while ether funds shed about $60 million and SOL funds lost nearly $10 million, their ninth straight day of withdrawals. SOL and ether each gained more than 3%, to about $106 and $2,450, while bitcoin ETFs drew a net $5 million, a thin inflow after Wednesday's $261 million exit. The article says a second straight day of bitcoin ETF inflows would be the first sign that the bounce from $80,000 has buyers behind it.
- Zcash Tanks Double Digits After 'Meteoric Rise' Sees Leverage Build Up
Privacy-focused cryptocurrency Zcash fell 11% over 24 hours to a market capitalization of $18.5 billion, one of the day's biggest losers. Luke Nolan of CoinShares attributed the drop mainly to a build-up of leverage after the token's 'meteoric rise', noting that $17.9 million of Zcash long positions were liquidated in 24 hours, versus $7.3 million for Hyperliquid, per CoinGlass. Other commentators pointed to concerns that AI could break crypto encryption before quantum computers do, which also weighed on Zcash. Nolan said the token remains up 460% from its March lows and that a French proposal requiring reporting of crypto holdings of €100,000 ($112,000) or more had little to do with the move. Zakura, a Zcash full node developer, expects Zcash to be quantum-proofed and reasonably AI-proofed by January.
- Zcash Continues to Outperform Every Other Major Cryptocurrency This Year. So Is ZEC Now a Buy?
As of Oct. 13, Zcash (ZEC) is up 121% year to date, more than eight times the gain of the best performer among the largest cryptocurrencies. On Oct. 7, crypto security researcher Justin Drake warned AI could crack wallet cryptography “in months, not years,” and ZEC fell 14% over the following 24 hours. The article says Zcash appears better prepared than its peers: on May 29, an AI-assisted audit found a critical vulnerability in a private pool, and on July 28, developers published a machine-checked proof covering more than 2,700 theorems, though the risk that AI undermines cryptographic math rose after OpenAI released 722 AI-generated math manuscripts on Oct. 6. Zcash Open Development Lab chief Josh Swihart said a full quantum-resistant upgrade could take 12 to 18 months, while Ethereum co-founder Vitalik Buterin warned AI math could weaken some quantum-resistant cryptography. The author concludes ZEC may suit investors who can tolerate volatility, as a small position.
- Coinbase, which holds 5% of all bitcoin, wants the quantum fix started now
Coinbase, which holds about 5% of all bitcoin in existence for clients including banks, asset managers and hedge funds, says Bitcoin should start preparing now for quantum computers. Google researchers cited in the article say a cryptographically relevant quantum computer could exist by 2029 and could derive private keys from public keys to drain vulnerable wallets. Coinbase recommends flexible post-quantum signatures, staged adoption, reliable implementations, and systems that serve both individual users and institutions using multiparty security. It argues that dormant or late-migrating wallets should be handled separately so they do not delay broader protections. Coinbase notes that Bitcoin consensus changes and ecosystem migrations can take years, so the work must start well before any such machine is announced.

- Duong Son Ba Arrested, Hai Phong Thermal Power Loses Lawsuit and Must Pay VND 115 Billion to Partner
Hai Phong Thermal Power (HND) disclosed an appellate ruling in a coal supply dispute with Dan Ka Mineral, under which the court accepted the plaintiff's appeal and ordered the company to pay nearly VND 115 billion, including a coal price difference of over VND 80.15 billion and interest of over VND 34.65 billion. The dispute stems from a 2021 contract, with disagreement over price adjustments after global coal prices rose sharply in 2022. Duong Son Ba, the company's general director, was arrested on 21 May 2026 over alleged forgery of documents of an agency or organisation, and the board dismissed him from the post on 13 October, with no successor yet announced. In the first half of 2026, the company reported net revenue of nearly VND 6,081 billion, up 8%, and after-tax profit of over VND 508 billion, up nearly 25%.
- Iran threatens to use the 'father of all missiles' to strike adversaries' energy facilities
Major General Mohammad Reza Naqdi, senior adviser to the IRGC commander, said at a rally in Sari on October 18 that Iran has prepared the most advanced missiles and will respond to any aggression. He warned that energy infrastructure and investments belonging to powers Tehran deems aggressive in the region could fall within Iranian missile range. His remarks answered US President Donald Trump's threat to use the GBU-43/B MOAB, often called the 'mother of all bombs' and weighing about 14 tons, against Iran's energy infrastructure and nuclear sites. Naqdi said Iran also possesses these bombs, having seized some that failed to detonate in the 12-day war, and called Trump's impatience a 'public admission of defeat'.
- Strategy on verge of golden cross, just weeks after bitcoin flashed same bullish signal
Strategy (MSTR) is about to form a golden cross, when its 50-day average rises above its 200-day average, possibly as early as Monday, just weeks after bitcoin showed the same bullish signal. The company holds $69.81 billion in bitcoin, and its stock has had two earlier golden crosses followed by big rallies: from $15.57 in September 2020 to $127.29 by February 2021, a 717% gain, and from $25.29 on March 2, 2023 to a peak of $473.83 in November 2024, up 1,774%. The article stresses the signal is unreliable, though: since 1999 MSTR has had 19 golden crosses, and only 10 were followed by a higher price 12 months later, a 50% hit rate, with a median 12-month return of just 3.3%. The two worst cases, in 2001 and 2007, were followed by a 61% loss.
- Director of the HCMC Institute of Economics, Natural Resources and Environment: Four major corporations have raised plans to invest in Vietnam, but pulled back when asked about power capacity
At a seminar co-organized by Tien Phong newspaper and the HCMC Department of Construction on October 16, TS. Phạm Viết Thuận said the city should treat infrastructure as an integrated system rather than focusing only on transport. He argued that 11 main and 13 secondary infrastructure categories, including power, water drainage, industrial zones and logistics, need to be synchronized for the city to develop its economy. To address flooding, he proposed surveying 159 flood-prone points and building ecological lakes at major spots. He also noted that four large corporations had considered investing in Vietnam but withdrew when asked about grid power capacity. Department director Trần Quang Lâm said capital mobilization and land policy need further study, while traffic congestion, flooding and pollution remain the city’s top priorities.
- Live updates: Bitcoin tags $83,000 and slips back as chip stocks lead a rebound
Bitcoin climbed from an overnight low near $80,700 to just above $83,000 early Monday, then slipped back to about $82,400 as sellers stepped in, and was up 0.3% over 24 hours. The bounce followed tech stocks, with Nasdaq 100 futures up 1.1%, snapping a weeklong 5.5% selloff, and an ETF tracking chipmakers jumping 3%. WTI crude recovered to $98.55 after touching $96.72, as the U.S. warned citizens across 12 Middle East locations of possible flight cancellations and airspace closures, raising fears of fresh strikes on Iran and disruption at the Strait of Hormuz. In Europe, the Stoxx 600 fell 0.8% after protests in France. Bitcoin would need to move through $84,000, its ceiling on October 13 and 14, to signal that the tech rebound is lifting it too.
- Baystreet . ca - When Might October Nasdaq Correction End ?
The Nasdaq Composite (QQQ ETF) is 6.96% below its 52-week high after falling 5.52% last week, close to the 10% threshold for a technical correction. The article says high oil prices, sustained by Iran's control of traffic through the Strait of Hormuz, keep September CPI and PPI rising, and that Iran wants higher oil prices to hurt the Republican Party before the midterm elections, so the correction in beaten-down stocks may continue. CoreWeave (CRWV) lost 25.21% last week, closing just 3% above its yearly low, while bears holding a 17% short float bet its $50 billion debt is unsustainable. Nebius (NBIS) fell 25% and Twilio (TWLO) dropped 15.6%, while Autodesk (ADSK), Salesforce (CRM) and Adobe (ADBE) drew buying. The article suggests volatility may ease after the midterms.
