- Crypto Firms Launch Quantum Alliance as 6 Million Bitcoin Sit Exposed
Nine blockchain organizations launched the Quantum Alliance, an open standards body that will define “quantum-ready” and set common ways to test quantum-resistance claims. The group warns that roughly 6.04 million BTC, about 30% of supply, is quantum-exposed because of elliptic-curve signatures, with forecasts pointing toward the late 2020s. A Google Quantum AI study cut the qubits needed to break Bitcoin’s cryptography to under 500,000, though no machine can do it yet. Modeled on the IETF, the Alliance will work in four groups covering migration, zero-knowledge systems, wallet security and cross-chain compatibility. Separately, a consortium backed by BlackRock, Strategy and Coinbase has committed $15 million to the problem.
- Satoshi-era bitcoin faces a bigger quantum threat after Google’s new Willow breakthrough
Google says its Willow chip cut errors about 40-fold when preparing “magic states,” a resource needed for quantum calculations that could one day threaten bitcoin wallets, and the result was published in Science. The approach reached about 99.99% fidelity for states that passed inspection, but only about 8% of preparation attempts succeeded and scaling remains difficult. The article stresses this does not make a bitcoin attack 40 times cheaper, as one modeled attack would still need roughly 500,000 reliable magic states per second. Some of bitcoin's oldest holdings have had their public keys exposed since they were mined, giving an attacker more time; for example, 100.02 BTC untouched since July 2010 moved on 7 October, worth about $8.5 million.
- Quantum could end bitcoin — or not. Here's why not to panic.
Coinbase said this week it is working on preparing Bitcoin for post-quantum readiness. Google Quantum AI said it demonstrated magic state cultivation, which could be a practical solution to one of quantum computing's most severe bottlenecks. The host argues quantum is a small issue that will likely be addressed in time, and does not place it in the same category as fears that AI will destroy humanity.
- Morning Minute: Google Clears a Major Quantum Hurdle, Bitcoin Still Safe
Google Quantum AI reported cutting a critical class of quantum errors roughly 40-fold on its Willow chip, according to a new paper in Science. Instead of building dedicated qubit factories, the technique injects a rough state, runs it through checks and discards the 92% that fail, leaving states with 99.99% fidelity. Breaking RSA-2048 would require error rates around one in 10 billion, and the estimated qubits needed fell from 20 million in 2019 to under one million by 2025. A March 2026 Google whitepaper put Bitcoin's elliptic curve cryptography at under 500,000 physical qubits, while Willow has 105. Justin Drake warns AI-driven mathematics could break elliptic curves first and advises large holders to move funds to fresh addresses that have never signed a transaction, while Coinbase, Sui, Ethereum, Zcash and Near are preparing quantum-resistant measures.
- Quantum Alliance forms amid warnings 6.4 million bitcoin face future quantum threat
Nine crypto companies have launched the Quantum Alliance to develop common security standards for bitcoin, Ethereum and other blockchains against future quantum attacks. Experts warn that a future quantum computer could derive secret keys from publicly visible keys, putting an estimated 6.4 million bitcoin at risk, including 1.1 million attributed to Satoshi Nakamoto; the Alliance says 30.2% of supply has exposed public keys, but no existing machine can exploit them yet. Researchers disagree on timing, with Richard Carback calling 2028 realistic. Proposals to freeze, move or place vulnerable bitcoin in a trust have raised concerns about property rights and neutrality, and any upgrade would require coordination across the Bitcoin ecosystem.

- Jobless claims near the lowest since the 1960s as low-fire trend continues
Employers are holding on to workers even as hiring stays weak, pushing seasonally adjusted initial jobless claims to 194,000 for the week ending Oct. 17, close to the 189,000 reported for the week of July 18, which was the lowest since the late 1960s. Claims have averaged 212,000 over the past year, and the four-week moving average has fallen to 197,750. The labor market backdrop remains uncertain: nonfarm payrolls rose only 29,000 in September and have averaged 69,000 a month in 2026, while the unemployment rate rose to 4.2%, largely due to a sharp jump in labor force participation. Layoffs remain modest, falling by 61,000 in August, and the layoff rate fell to 1% over the prior 12 months. Ahead of the Federal Reserve's decision next week, policymakers describe the labor market as generally strong and are focused on inflation, which remains well above the 2% target; markets expect the Fed to hold in October and then raise rates by a quarter point in December.
- Temporary Delays in siRNA Manufacturing Mask Codexis' (CDXS) High-Option Value
In its Q3 2026 investor letter, White Brook Capital highlighted Codexis (NASDAQ:CDXS), which makes enzymes used to manufacture siRNA-based medicines, and said the stock holds call options with favorable payouts. On October 21, 2026, the stock closed at $1.29 with a market capitalization of $141.26 million, down 20.86% year to date and trading within a 52-week range of $0.96 to $2.98. However, 2026 has been marked by delays: three CDMO partners, Bachem, Nitto Denko Avecia and Axolabs, were signed early in the year, but only one has completed its technology evaluation, and long-term contract negotiations are still ongoing. Permitting delays have also hit its GMP-standard standalone facility, which is now scheduled to start production at year-end 2027, and the target for half-kilogram siRNA batches has moved to the end of this year or early next year.
- Evaluating CareCloud's (CCLD) Short-Term Integration Friction vs. Long-Term Margin Expansion
On October 21, 2026, CareCloud (NASDAQ:CCLD), a healthcare IT company providing billing, medical-records and AI software, closed at $1.77 with a $75.21 million market cap, down 39.38% year to date. In its Q3 2026 investor letter, White Brook Capital said the market's frustration stems from declining profits as the company integrates acquisitions. Second-quarter revenue grew 16%, but net income fell to just $1.1 million due to merger costs, heavier AI spending and interest on new debt, and a March cyberattack added to the strain; management expects insurance to cover the costs, though this shook investor confidence. The company also retired the preferred stock White Brook previously held in May, saving about $3.3 million annually, and management expects a stronger second half than first. At roughly eight times the midpoint of management's 2026 GAAP EPS guidance, White Brook sees double-digit revenue growth at a modest multiple, with additional upside if integration improves margins.
- VIX Securities Still Holds VND 1,000 Billion of Undisbursed Capital from Share Offering
VIX Securities (HoSE: VIX) raised over 11,026 billion VND from an offering of nearly 919 million shares priced at 12,000 VND each on April 20, 2026. Over 5,013 billion VND each was disbursed to proprietary investment and margin lending from April 22 to May 26, 2026, but the 1,000 billion VND earmarked to contribute capital to VIX's digital asset trading exchange had not been disbursed as of October 20, 2026. In Q3 2026, pre-tax profit fell nearly 94% year on year to 192 billion VND, with revenue down 36% to 2,047 billion VND and proprietary trading booking a net loss of 94 billion VND. For the first nine months, revenue fell 18% to 5,050 billion VND and pre-tax profit dropped nearly 92% to about 424 billion VND, mainly due to proprietary trading losses, leaving VIX at 12.1% of its 3,500 billion VND full-year pre-tax target. Total assets rose 16.6% to nearly 39,860 billion VND by September 30, 2026, while margin loans fell from 15,380 billion VND to 12,422 billion VND.
- Chip stocks fall as equipment maker Lam Research cites 'supply chain constraints'
Semiconductor stocks fell in premarket trading Thursday after Lam Research, a major wafer equipment supplier, cited near-term supply chain constraints on its earnings call. Its CFO said quarterly revenue guidance of $8.6 billion would have been a bit higher without these constraints, and Lam shares fell as much as 9% premarket. The PHLX Semiconductor Index (SOXX) was set to open down 4%, with Nvidia and Qualcomm down more than 2%, Marvell down 4%, Intel down 5%, Broadcom down more than 3%, Applied Materials down 6% and ASML down 3%. Semiconductor stocks have been volatile as concerns over AI funding weigh on the sector, while surging oil prices raised expectations that the Fed may keep tightening monetary policy this year.
- VN-Index rises another 22 points, reaching highest level in over half a year
The VN-Index closed at 1,761 points, up 22 points, on trading volume of more than 672 million shares worth about 15,300 billion VND. On HoSE, 149 stocks rose, 167 fell and 57 were unchanged. Foreign investors net bought nearly 342 billion VND on HoSE, led by VIC (over 239 billion VND), TCB and VHM, while FPT saw the largest net selling at over 264 billion VND. ASEAN Securities said the index shows a technical rebound signal with buyers temporarily in control, but the market remains neutral because the index has not broken above the MA20 and indicators are not yet uniformly confirmed, so it may trade in a narrow range.
