Morning digest: October 6, 2026

Tuesday’s crypto news is mostly about plumbing for institutions and regulators. Solana got an audited delivery-versus-payment settlement program shaped by JPMorgan. North Dakota’s state bank began piloting a bank-to-bank dollar token on Solana. Treasury dropped two long-pending crypto surveillance proposals, and the CFTC is moving on retail crypto leverage rules without waiting for Congress. Glamsterdam goes live on Sepolia this morning. In health, a new ACP guideline makes hormone therapy first-line for hot flashes, and two small trials look at older adults. At home, a White House diesel-tax order meets pump prices that have barely moved, and Virginia early voting is running at more than double the 2022 pace. In science, a preprint claims a proof of the Linear Hadwiger conjecture, and its authors say an AI model came up with the core ideas.

Blockchain: settlement rails, a state-bank token, and Washington steps back on surveillance

The Solana Foundation released Solana DvP, an open-source, externally audited program for settling institutional trades. DvP means delivery-versus-payment: the asset and the cash move in one atomic transaction, so neither side can deliver without getting paid. Settlement takes seconds instead of T+1 or T+2. Until now, institutions on Solana have mostly written their own settlement contracts. JPMorgan’s digital-assets markets team helped set the requirements: settlement deadlines, a separate escrow for each trade, and support for the Token-2022 features regulated issuers use, such as pausable tokens and transfer hooks that can enforce allowlists. The foundation says it’s ready for real funds, and confidentiality features are planned. (CoinDesk)

The Bank of North Dakota launched a pilot of Roughrider Coin. It’s a permissioned, fully reserved dollar “token deposit” that only financial institutions can use, not consumers. VersaBank USA issues it, it runs on Fiserv’s new Digital Asset Platform, and it settles on Solana, with BND acting as governor. Four institutions are in the pilot: Gate City Bank, First International Bank & Trust, Capital Credit Union, and North Star Community Credit Union. Access will widen in phases. It gives community banks a template for real-time settlement without building their own systems. (BND; North Dakota Monitor via Yahoo; The Dakotan)

In a parallel move on cross-border payments, ANZ became the first Australian bank to make a live payment on Swift’s blockchain-based shared ledger. Working with Citi and BHP, it sent U.S.-dollar treasury payments between Melbourne and New York. Tokenized deposits moved behind the scenes while BHP used its normal ANZ channels. (Finextra)

Regulators: FinCEN withdrew its 2020 proposal that would have made banks and exchanges report transfers over $10,000 to or from self-custodied (“unhosted”) wallets. It also withdrew a 2023 proposal to label crypto mixing a primary money-laundering concern. Neither had taken effect, but both had hung over self-custody and privacy tools for years. (CoinDesk) Separately, the CLARITY market-structure bill stalled in the Senate, so the CFTC issued an advance notice of proposed rulemaking, an early request for public comment. It would create a federally regulated “crypto asset market” where retail customers could trade with margin or leverage under one federal regime instead of a patchwork of state rules. This runs alongside the SEC’s own proposed crypto-securities regime. (Cointelegraph)

Security: ZachXBT says he went undercover as a client of a Chinese laundering network that moved more than $1B for North Korea’s Lazarus group, fronting about $350K in USDC. His work exposed a wallet cluster of more than $12M tied to the $1.5B Bybit hack, and Tether reportedly froze about 442,000 USDT. On defense, the Ethereum Foundation proposed transaction assertions. Today a signature covers only what a transaction asks to do, not what actually happens. Under the proposal, a transaction would carry rules about its outcome, such as “the Safe’s implementation must not change” or “I must receive at least X tokens,” and it would revert if a rule is broken. That targets the swapped-front-end attacks behind Bybit and BadgerDAO, and EIP-7906 is one candidate design. (Cointelegraph; Decrypt; EF blog)

Also: Ark Invest put its ARK Venture Fund (which holds stakes in Stripe, Databricks, and others) onchain with Securitize as an Ethereum token with daily NAV and transfers around the clock. (InvestingChannel) Glamsterdam activates on Sepolia today at about 9:54 a.m. ET. It brings enshrined proposer-builder separation, which removes the need for trusted relays, and block-level access lists that let clients process transactions in parallel. (EF)

Market: Bitcoin was rejected at $87,000 for the third time since Sept. 23 and slipped to about $85,600, even as the Nasdaq 100 closed at a record. The 10-year Treasury yield hit 5.32%, and total crypto market cap is about $2.9T. (CoinDesk)

Health: hormone therapy first-line, low-dose cuffs after 70, and peanuts

The American College of Physicians’ new guideline (Annals of Internal Medicine, Oct. 6) strongly recommends estrogen-based hormone therapy as first-line treatment for menopausal hot flashes and night sweats. That means estrogen plus a progestogen for women with a uterus, and estrogen alone for women without one. For women who can’t take estrogen, the second-line option is an SNRI (desvenlafaxine or venlafaxine). Third-line options are an SSRI, gabapentin, or a neurokinin antagonist (elinzanetant or fezolinetant). If symptoms are disrupting sleep or daily life, there’s now a guideline behind bringing this up with a clinician. (ACP; DOI)

In a small randomized trial of 20 adults over 70, two 15-minute sessions a week of easy cycling with blood-flow-restriction thigh cuffs for six weeks improved mobility scores more than sham cuffs. The gains came close to a clinically meaningful difference, along with about 17 kg more on leg press and better vitality scores. Walking tests didn’t differ between groups, and there were no adverse events. The trial was tiny and short, and cuff pressure was set individually by therapists, so this isn’t a do-it-yourself prescription. (Frontiers)

A 16-week crossover trial in 31 healthy adults aged 60–75 found that 60 g a day of unsalted, skin-roasted peanuts (about two servings) improved how the brain’s memory regions responded to insulin on MRI. An earlier report from the same trial found better cerebral blood flow and verbal memory. The sample was small, the outcomes are surrogate measures, and the Peanut Institute Foundation funded the work, so it’s promising but not settled. (EurekAlert; DOI)

General / local: diesel order, pump prices, Virginia early vote

President Trump signed an executive order dated Oct. 5 that gives Treasury five days to decide whether to defer federal diesel excise tax (24.4¢ a gallon) incurred Oct. 5–Dec. 31. It also tells the IRS not to penalize highway use of tax-free red-dyed (off-road) diesel over the same period. The White House puts the savings at about $60 per 250-gallon fill, or more where states match. Actual pump effects depend on Treasury guidance and state action. (White House; CNBC)

So far the order doesn’t show at the pump. AAA has national diesel at $6.32 and regular at $4.37. In Virginia, diesel is $6.25 and regular is $4.16, both still under the national average. Diesel is well below the Sept. 22 record of $6.53. (AAA)

Virginia early voting reached 183,217 ballots through Sunday, compared with 75,819 at the same point in 2022, about 142% ahead. The 1st, 5th, and 11th districts lead. Key dates: Oct. 23 is the last day to register for a regular ballot and to request a mailed absentee ballot. Weekend early-vote days are Oct. 18, 24, 25, and 31, and in-person early voting ends at 5 p.m. Oct. 31. (The Center Square; Virginia ELECT)

Nothing changed overnight on sending money to Russia. OFAC’s Lukoil licenses still run to Oct. 22 and Oct. 29 and still forbid any transfer of funds to a person or account in Russia. (OFAC FAQ 1225)

Science: Linear Hadwiger conjecture claimed, with AI-found proof

Sergey Norin (McGill) and Raphael Steiner (ETH Zurich) posted a preprint (arXiv 2610.05291) that claims to prove the Linear Hadwiger conjecture. It says every graph with no K_t minor can be colored with C·t colors for some absolute constant C. That’s the best possible order of growth. The previous best was O(t log log log t), and before that the bound sat at O(t log t) for decades. The full Hadwiger conjecture, exactly t − 1 colors, is still open. The authors say OpenAI’s model Astra 6 developed the proof under their direction, including the key new “bootstrap” step, and that OpenAI Codex produced a Lean formalization of the whole argument. The preprint hasn’t been peer reviewed, and nobody independently checked that the Lean project builds cleanly. If it holds, it’s a major result in graph theory and one of the clearest cases yet of an AI supplying the main ideas of a research-level proof.

Bottom line

Crypto keeps building institutional plumbing: an audited Solana DvP standard, a state-bank dollar token, and ANZ’s live payment on Swift’s ledger. Meanwhile, Washington dropped its unhosted-wallet and mixer proposals, and the CFTC is pushing ahead without Congress. Bitcoin stalls below $87K, and Glamsterdam hits Sepolia at 9:54 a.m. ET. In health, hormone therapy is now guideline first-line for hot flashes. The diesel-tax order hasn’t reached Virginia pumps yet (diesel near $6.25), early voting is more than double the 2022 pace, and a possible AI-assisted breakthrough in graph theory awaits peer review.
