Blockchain: Binance’s proof, a Brazilian hack, bitcoin under $77K
Binance opens phase two and publishes its proof of reserves. Binance has been reopening withdrawals in stages since last week’s record ~$6.3 billion hot-wallet theft, which the FBI attributes to North Korea’s TraderTraitor group; North Korea denies it. Phase two started at 04:00 UTC today (11 p.m. ET Monday) on networks including BNB Smart Chain, Ethereum, Solana and Base, restoring 31 more Ethereum tokens and 20 Solana tokens; deposits stayed open throughout. On Monday Binance completed its zero-knowledge proof of reserves for the Oct. 31 snapshot, a cryptographic check you can run yourself that customer balances were fully backed at that moment, covering BTC, ETH, USDT, BNB, SOL, USDC, XRP, USD1, RLUSD and ZEC. It’s a point-in-time check, not a full audit. Binance says it has replaced about 95% of the stolen assets with its own funds and is still buying the less liquid last 5%; a wider snapshot is planned for Wednesday, with its proof 40–50 hours later. DefiLlama shows 24-hour net outflows easing from a ~$7 billion peak to ~$3.5 billion, and Binance told Reuters hourly deposits are now exceeding withdrawals. Elliptic says about $2.85 billion of the stolen funds is frozen or seized; the rest is being laundered across many chains (The Block; crypto.news; Reuters via Euronext; Binance PoR).
Mercado Bitcoin loses about $38–49 million. Early Monday an attacker drained hot wallets at Brazil’s largest exchange across 10 to 17 blockchains in waves, mostly BTC and ETH plus funds on Base, Tron and Polygon. The exchange went offline, says cold storage and customer data weren’t touched, and has pledged to cover all losses. Tether, Circle, Paxos, the BRL1 issuer and Chainalysis helped freeze about $11 million, leaving an unfrozen loss of about $38 million by the exchange’s count; some researchers dispute its claim that customer wallets were untouched. It’s the second big exchange hot-wallet breach in a week (CoinDesk; Chainalysis).
Bitcoin below $77K, lowest since early September. Bitcoin fell about 2% to roughly $76,800–76,900, erasing Monday’s bounce. Ether is near $2,250, SOL near $92 and BNB near $696, and the Fear & Greed index is at 26 (“fear”). Drivers: a chip and AI stock selloff, spot bitcoin ETF outflows after the Binance hack ($643 million on Oct. 30, the most in four months), and hedging ahead of today’s midterms, which decide who controls crypto legislation. Options expiring Nov. 4 price noticeably more volatility than later dates (CoinDesk; Investing.com).
SEC staff: broad token voters aren’t a “central party.” The SEC’s Division of Corporation Finance added three crypto FAQ entries on Nov. 2. Unaffiliated participants in broad on-chain governance generally don’t count as a controlling central party unless they coordinate outside governance and hold operational, economic or voting control. The FAQ also separates a “functional” system (the token works as programmed) from a “decentralized” one (no controlling parties), the tests that matter for DAO-governed protocols (SEC FAQ; crypto.news).
Briefly:
- New Jersey drops its Coinbase staking case. The state rescinded, without prejudice, its 2023 cease-and-desist and $5 million penalty over Coinbase’s staking service, so New Jersey users can stake again; one of the last state staking actions from the 2023 wave (Cointelegraph).
- Standard Chartered tokenized deposits in Hong Kong. The bank launched tokenized deposits for corporate clients, with live transactions including settlement of tokenized money-market funds over the HKMA’s EnsembleTX, which now counts 12 banks and 20 industry participants (Standard Chartered; HKMA).
- RDUSD: a US-bank stablecoin for Hong Kong (announced, not live). Anchorage Digital Bank, an OCC-chartered trust bank, will issue RDUSD for Hong Kong’s RD Technologies, backed 1:1 by dollars at Anchorage and native to HashKey’s HSK Chain; HashKey will be its main market maker. Not HKMA-licensed, so professional investors only in Hong Kong; no launch date yet (Stablecoin Insider).
- Stellar votes on Protocol 30 testnet today. The Bell upgrade vote is at 17:00 UTC (noon ET) and includes post-quantum ML-DSA signature checks for smart contracts and millisecond ledger timing; a scheduled vote, not an activation (Stellar).
- Ethereum Foundation pitches governments. A new site for governments, NGOs and multilateral bodies argues Ethereum suits digital public infrastructure because no single organization controls it, with case studies including Bhutan’s digital ID (EF blog; site).
Health: heat-trained runners, the intensity sweet spot for your brain
Trained runners: seven hot runs, equal gains for women and men. In a randomized crossover trial, 18 highly trained endurance runners (8 men, 10 women) did seven 60-minute runs at 50% of vVO2max in 40 °C heat and, separately, seven at 22 °C. Heat produced bigger drops in core temperature and heart rate and more sweating than the cool block, with no sex differences in how fast or how much they adapted. How to use it: about seven easy hour-long runs in hot conditions before a hot race build adaptation that cool-weather training only partly gives. Limits: small, no performance outcome, elite-level runners only (Journal of Applied Physiology).
Thinking skills peak at moderately hard effort. In a 12-week RCT, 250 university students were randomized to five exercise-intensity arms, twice a week. Working memory and attention followed an inverted U, peaking near 67% of heart-rate reserve (95% CI 63.1–71.2%), with the best zone about 60–74%; performance fell about 1.46 times faster above the peak than it rose below it. How to use it: target heart rate ≈ resting HR + 0.60–0.74 × (max HR − resting HR); going harder was worse for these outcomes than going easier. Limits: general population of young, healthy students, single site, single author, tentative pending replication (BMC Psychology).
Mild cognitive impairment: Baduanjin and Tai Chi lead. A network meta-analysis of 44 RCTs (3,189 people with MCI, a clinical group) found Baduanjin, Tai Chi, Qigong and dance all beat control on the MoCA; Baduanjin ranked first (SUCRA 91.6%), best in short, frequent programs (≤12 weeks, more than 3 times a week, under 60 minutes), while Tai Chi did better in longer programs. Low certainty, indirect comparisons (Aging Clinical and Experimental Research).
Learning an instrument held the brain steady in MCI. In a randomized pilot, six months of intensive group instrument training kept hippocampal functional connectivity stable (it declined in healthy controls) and gave a marginal global-cognition gain; psychomotor training also held connectivity steady. Pilot, clinical group, no effect sizes in the abstract (Annals of the New York Academy of Sciences).
Briefly:
- Sleep after 60: mix cardio and strength. A network meta-analysis of 32 RCTs (2,658 older adults) ranked combined aerobic-plus-resistance exercise first for sleep quality (SUCRA 74.8%), ahead of aerobic, resistance, mind-body and dance; rankings only, called provisional (European Geriatric Medicine).
- Older adults with diabetes: training builds strength, not mass. A meta-analysis of 11 RCTs (≈740, mean age 65+, clinical) found exercise raised strength (g = 0.67) and physical performance (g = 0.74) and cut HbA1c by 0.32 points, while lean mass barely moved; no serious complications (Geriatrics & Gerontology International).
- Eight weeks of four lifts speeds walking. In 851 Taiwanese adults 60+, a four-movement progressive resistance program raised gait speed 0.13 m/s more than assessment only, above the 0.10 m/s clinically important threshold; already-slow people gained most (+0.21 m/s). Non-randomized, only 40 comparators (European Review of Aging and Physical Activity).
- Breathing-muscle training for team-sport athletes. A meta-analysis of 10 studies found inspiratory or respiratory muscle training raised inspiratory strength by about 26 cmH2O and performance (SMD 0.85); low to very low certainty (BMC Sports Science, Medicine and Rehabilitation).
- Monk-fruit blends blunt the drink spike, not the meal. In a double-blind crossover trial (30 healthy adults), three monk-fruit blends gave lower glucose and insulin after the drink than sugar, but responses after a standard meal, appetite and intake didn’t differ; more diarrhea, patent-holder authors, part sugar-company funding (European Journal of Nutrition).
- SRSF1 and aging, in mice. A Harvard/Wyss team (Church lab) in Nature Aging found raising the splicing factor SRSF1 made aged human cells look transcriptionally younger and, in aged mice given it by gene vector, slowed frailty by 44% with a 14% longer median lifespan (n = 9–10 per group). This is a cell and mouse study, a gene-therapy target with no human trial or dose; some authors cofounded a related company (Nature Aging).
General and local
Election Day. Polls in Virginia are open 6 a.m. to 7 p.m. (Prince William Times).
Tech slides, Apple dips, ISM beats. Monday the Nasdaq fell 1.07% and the S&P 500 0.51% as money rotated out of tech, while the Dow rose 0.41%; Oracle dropped 8% after announcing a $20 billion stock-and-bond raise for its AI build-out. Apple’s fiscal Q4 revenue ($114.5 billion) and EPS ($2.10) beat, but China sales and margin guidance disappointed, and shares were down about 2–4% premarket. This morning Dow futures are about −0.5%, S&P flat and Nasdaq-100 +0.4%, with the 10-year yield up to 4.91%. October ISM manufacturing rose to 55.5 (54.5 expected), its 10th straight month of expansion, with prices paid at 75.2. JOLTS and factory orders are out today, AMD reports tonight and the jobs report is Friday. Prediction markets put Democrats’ Senate odds near 75%, and JPMorgan warned a Democratic sweep could hit AI stocks (CNBC; TipRanks; ISM).
Briefly:
- Fatal Centreville Road crash. Dmitry Vazquez, 33, of Manassas died early Saturday when, police say, his BMW crossed into oncoming traffic near Rugby Road and hit a Ford Explorer; its three occupants had non-life-threatening injuries (Patch).
- Two Woodbridge teens hurt. A 16-year-old was seriously hurt in a Halloween-night stabbing on Tassia Lane, and a 17-year-old was assaulted by two strangers at Marumsco Plaza early Sunday; police have no suspect descriptions (Potomac Local).
Lighter note: the napkin bandit. Prince William police are investigating two “burglaries” at the Old Bridge Road Chick-fil-A in Woodbridge, on Oct. 13 and Oct. 31. Both times a man forced open a side door, went in, took a stack of napkins and left (Potomac Local).
Lighter note: “too darn fat to fly.” A red-shouldered hawk found grounded in a Roanoke driveway had no injuries; vets at the Southwest Virginia Wildlife Center said she was simply “too darn fat to fly,” at more than 910 grams (about 2 pounds), nearly a pound over normal, so fat they couldn’t feel her keel. A neighbor’s free-roaming chickens had been “disappearing at an alarming rate.” She’s now on a diet, and the center asks people to cover chicken runs (UPI; AOL).

Science
Specialists re-prove a 60-year-old problem first cracked by AI. The Harary–Hill conjecture, open since about 1960, gives the fewest edge crossings possible when you draw a complete graph (every point joined to every other). OpenAI’s October math release included a short polynomial-method proof with a Lean formalization. Now two crossing-number specialists have independently rewritten it: Gelasio Salazar, a central figure in the field, posted a complete proof for combinatorialists on Nov. 3 that establishes a stronger purely combinatorial statement, and Martin Balko (Charles University) posted a streamlined version needing only elementary linear algebra and graph theory. Before this, humans had proved it only for restricted kinds of drawings and checked it by computer up to 14 points. Caveats: neither paper is refereed, and both follow OpenAI’s idea rather than an independent route (Salazar, arXiv; Balko, arXiv).
Curious idea: did the Moon squeeze out Earth’s first continents? In a modelling study in JGR: Solid Earth, Simon Lock (University of Bristol) proposes that if the Moon-forming impact left Earth spinning with days only a few hours long, the planet would have bulged at the equator with thick crust there. As tides pushed the Moon outward and the spin slowed, the bulge relaxed, compressing equatorial crust at rates he compares to the Himalayas today. The cracking could have let water and CO2 into the crust, driving the melting that makes buoyant continental rock within roughly the first 200 million years, possibly without plate tectonics. It’s a hypothesis, not a proven finding: it rests on the unproven “synestia” scenario and a simple model with little surviving rock to test it (Science).
Russia: Moscow and Voronezh
Moscow drone night; Voronezh alert. Sobyanin says 493 drones flew toward the Moscow region from 20:30 Monday to 07:30 Tuesday Moscow time, 187 of them downed on approach to the city; he gave no information on casualties or damage. Domodedovo and Vnukovo closed overnight, and all Moscow airports were back to normal by 08:02, so expect knock-on delays. Voronezh had a missile alert from 04:19 to 05:11 with no damage reported (Kommersant; Fontanka; VestiPK).
Bottom line
Binance’s proof of reserves and easing outflows are the recovery checkpoint, but a second exchange hack and bitcoin under $77,000 show the market is still nervous on Election Day. Run in the heat before a hot race, aim for moderately hard effort when you train for your brain, and keep lifting at any age. Polls close at 7 p.m., the napkin bandit is still at large, and one Roanoke hawk is on a diet.
