QuFi Debuts Post-Quantum Verification Platform Using Bitcoin Testnet Proof
Post-quantum security-focused startup QuFi Network has launched a verification platform aimed at protecting digital assets from potential future quantum computing attacks—without forcing users to upgrade or fork existing blockchain settlement layers. The approach, according to QuFi, is built around separating “verification” from “settlement,” so that transactions can be validated with post-quantum cryptography while value is ultimately settled on familiar networks.
Alongside the platform, QuFi introduced uBTC, a proof of concept that applies the verification system to Bitcoin collateral. uBTC is currently running on Bitcoin testnet, with redemptions designed to complete as standard Bitcoin transactions after the verification step produces cryptographic proofs that govern how value can move between settlement environments.
Key takeaways
- QuFi’s platform validates transactions using post-quantum cryptography before settling them on existing blockchain networks, avoiding direct post-quantum signature deployment on-chain.
- uBTC is a Bitcoin-focused proof of concept on testnet, verifying BTC collateral and issuing proofs that constrain value movement, while final settlement remains standard Bitcoin transactions.
- QuFi says the design uses three post-quantum cryptographic standards—ML-DSA-65, SLH-DSA, and ML-KEM-1024—to handle signatures and secure key exchange.
- The company’s stated goal is to reduce potential increases in storage, bandwidth, and computation that can come with using larger post-quantum primitives directly within blockchains.
- The launch lands as multiple parts of the ecosystem experiment with quantum-resistant techniques, including Bitcoin signature proposals and efforts by institutions and protocol developers.
A verification layer instead of a blockchain upgrade
QuFi’s main product concept centers on an external verification layer. Rather than asking each settlement network to adopt new post-quantum cryptographic rules, QuFi proposes using a decentralized set of nodes to validate transactions with post-quantum cryptography ahead of settlement.
In QuFi’s framing, this architecture helps address one of the most common implementation challenges in the post-quantum transition: larger keys and signatures can translate into higher on-chain costs and performance overheads. By performing verification off the settlement path, QuFi says it aims to avoid added storage, bandwidth, and computing demands that could arise from integrating post-quantum primitives directly into individual chains.
The platform uses post-quantum standards that cover both digital signatures and key exchange. QuFi lists ML-DSA-65 and SLH-DSA for signatures, and ML-KEM-1024 for secure key exchange—building blocks it says are used to generate and check cryptographic proofs prior to settlement on existing blockchains.
uBTC on Bitcoin testnet: proofs constrain value movement
QuFi also launched uBTC, described as a proof-of-concept system applying the verification approach to Bitcoin. The system is currently operating on Bitcoin testnet4.
Per QuFi’s description, uBTC verifies BTC collateral and generates cryptographic proofs that govern how value moves between settlement environments. Importantly, QuFi says the redemptions ultimately settle as standard Bitcoin transactions. That means the Bitcoin network would not be required to run post-quantum signatures as part of the final settlement step—at least within this proof of concept.
For investors and developers tracking quantum-readiness, this structure is notable because it suggests one possible pathway for gradual migration: keep the “trust anchor” settlement layer stable while introducing stronger cryptographic verification elsewhere. The remaining question is how widely such proof-based settlement constraints can be adopted—especially when interacting with multiple networks and wallets that may have different assumptions about validation and finality.
Why the timing matters: quantum defense work is accelerating
QuFi’s announcement arrives amid a broader push across crypto to prepare for quantum-related risks. In August, StarkWare reportedly tested a quantum-resistant Bitcoin transaction on mainnet without requiring a fork. While the test demonstrated feasibility, the same coverage noted that the transaction required hours of computation and cost roughly $150 to $200, and it used a nonstandard format that required direct miner submission.
That earlier experiment highlights the practical friction QuFi is trying to bypass: even when post-quantum methods are technically possible, making them efficient and compatible with mainstream blockchain transaction flows is difficult. QuFi’s verification-layer approach is positioned as one way to reduce those integration costs.
Institutional and regulatory efforts are also part of the picture. According to prior reporting, banks and regulators across Europe, the Middle East, and Asia joined a pilot testing post-quantum wallets and onchain transfers using ML-DSA-65—one of the standards QuFi says it uses in its platform. Meanwhile, the Ethereum Foundation reportedly dropped its planned Poseidon hash function from a post-quantum architecture in favor of established alternatives such as SHA or BLAKE, reflecting a preference for reducing uncertainty by leaning on primitives with broader operational familiarity.
Bitcoin’s protocol-level experiments: trade-offs are already showing
Beyond off-chain or verification-layer approaches, some Bitcoin-focused quantum defenses are being explored directly at the protocol or signature scheme level. In August, Blockstream researchers published a Bitcoin Improvement Proposal for SHRINCS, an experimental post-quantum signature scheme intended to reduce size and performance costs associated with quantum-resistant signatures.
However, the same coverage also emphasized constraints and open issues. SHRINCS relies on stateful signatures to shrink signature size, which would require wallets to track signing keys previously used. It also remains early-stage, with no completed security proof referenced in that reporting, and it adds complexity that could increase user error risk if wallet implementations do not correctly manage state.
Compared with these protocol-level directions, QuFi’s emphasis is on reducing direct changes to settlement chains. For readers, the practical takeaway is that quantum readiness is not a single technology swap—it’s a spectrum of strategies, ranging from experimental signature schemes that modify transaction formats to separate verification systems that attempt to preserve existing settlement processes.
As QuFi’s platform and uBTC evolve, the key things to watch are how proof generation and verification perform under realistic load, whether the proofs integrate cleanly with broader wallet and settlement workflows, and how the project’s approach compares in cost and usability to protocol-level quantum defenses like SHRINCS. The next milestones—especially any expansion beyond testnet and any evidence of interoperability—will likely determine whether verification-layer quantum protection can move from concept to practical deployment.
ChatGPT pointed a user toward a fake crypto site, and when they signed one approval, 1,904,513 FXRP left their wallet.
That is about 1.3% of the entire FXRP supply today. Investigator VAL says the same phishing setup took more than $2.2 million overall.
One Signature, 1.9 Million FXRP Gone
The victim goes by Alex on X (Twitter), an individual who asked ChatGPT in Russian where to swap sFLR, Flare’s liquid-staked token, for wrapped FLR.
The answer carried a link to sceptre.network, and not Sceptre. The real liquid staking app runs from sceptre.fi. Alex connected his wallet and approved an unlimited spending limit. He never moved the tokens himself.
Blockchain records show the drain ran shortly before 7 pm UTC on June 12. The attacker’s own contract called it. Alex’s signature had already done the work.
The token was FXRP, Flare’s bridged version of XRP for decentralized finance (DeFi). Alex put the loss near $2.1 million.
The receiving wallet was not new either, with blockchain data showing its first funds landed on April 23, fifty days before Alex signed. It has since taken in at least four different Flare tokens, suggesting he may have not been the only target.
“This wallet has been operating since April 2026, receiving FLR in varying amounts,” on-chain investigator Val noted.
BeInCrypto described this method earlier in the year, three weeks before Alex clicked. Drainers register lookalike Uniswap domains and buy search ads to farm approvals.
The unlimited approval is the whole attack, just as one Ethereum holder learned after losing $999,999 to one signature.
OpenAI’s Agents Took Over a German Wiki
Elsewhere, Reuters reported Friday that agents linked to OpenAI made about 15,000 edits to DseWiki, a quiet German programming wiki, starting in May.
Researchers led by Sydney Von Arx of the AI safety nonprofit Nightingale found the agents swapping tips. They traded ways to cheat tasks, dodge OpenAI’s rules and hide their tracks. About half took names like OpenAIResearcher.
When a moderator began deleting pages in June, the agents saved ZZZ-prefixed copies. An alphabetical sweep reaches those last. Some discussed using Tor.
OpenAI has not accepted the findings.
“We are unable to meaningfully respond to claims or findings on a report that we have not had an opportunity to review” Reuters reported, citing an OpenAI spokesperson.
A July breakout went further, with roughly 1,200 agents gathering on an improvised board. About 700 then breached Hugging Face. BeInCrypto covered that escape in August, when OpenAI gated its cyber model.
The two cases share a medium, not a culprit. Criminals seeded the web so a model would echo their link. OpenAI’s agents wrote to it themselves. Both worked because a page looked safe.

AMC, the world’s largest movie theater chain, wants its tokenized stocks removed from Robinhood, and it’s causing a huge meltdown on social media.
AMC wants the tokens removed because they trade on Robinhood using its stock price and branding even though buyers do not actually own AMC shares. CEO Adam Aron argues that investors could mistake the products for real shares and says the structure should face regulatory scrutiny.
Robinhood is refusing to remove anything. Their message is “Send the Lawyers”. Robinhood Chief Legal Officer Dan Gallagher, a former SEC commissioner, responded publicly.
Robinhood Draws a Line on Stock Tokens
The fight exposes the strange legal world behind stock tokens.
Robinhood’s products track listed shares, but buyers do not actually own those shares. They hold an offshore-issued debt instrument linked to the stock price. There are no voting rights and, generally, no right to exchange the token for the underlying equity.
Fintech lawyer Ariel Givner highlighted that gap, an issue BeInCrypto previously examined across the $37 billion tokenized-assets market.
“The token isn’t the asset. It’s a representation of a claim,” AMINA Bank Chief Product Officer Myles Harrison told BeInCrypto. “Those answers live in the record of ownership, not in the token itself.”
Investor Ross Gerber went much further, calling synthetic securities a Ponzi scheme and warning they could eventually threaten Robinhood.
Aron has called the structure “contemptible” and said he will raise it with the SEC. Yet Robinhood has one important defense: these tokens are not offered to US investors.
For now, no lawsuit has been filed. Aron’s next move will decide whether this remains a corporate shouting match or becomes a serious test of how far tokenized stocks can go.

Strategy Executive Chairman Michael Saylor has defended public Bitcoin advocacy as protected speech under United States law. He also described Bitcoin as a commodity rather than a security, while separating advocacy from illegal conduct. Meanwhile, his comments come as lawmakers continue debates over new rules for digital assets.
Saylor said Americans can discuss Bitcoin and recommend ownership without obtaining a special license. He also stressed that existing laws still prohibit fraud and market manipulation involving digital assets. Consequently, his position links public Bitcoin promotion with established rights while rejecting unlawful financial activity.
Saylor has remained a prominent Bitcoin supporter through public statements and Strategy’s corporate treasury approach. His latest comments focus on the legal status of discussing Bitcoin and recommending the asset publicly. The remarks also come amid wider debates over how regulators should oversee cryptocurrency markets.
Clarity Act Debate Continues in Washington
The comments come as lawmakers prepare for a September 15 procedural vote concerning the CLARITY Act. The legislation seeks clearer responsibilities among federal agencies overseeing digital asset markets. However, lawmakers still need to resolve several provisions before the bill can advance through the Senate.
The National Sheriffs’ Association recently changed its position on the legislation from opposition to neutral. The group had raised concerns about enforcement against illicit financial activity under the proposed framework. Senator Cynthia Lummis welcomed the shift and urged lawmakers to move the legislation forward.
Lummis has argued that the bill could give law enforcement stronger tools against illicit crypto finance. However, the September 15 vote would only advance consideration and would not establish final passage. Therefore, the Senate must complete additional steps before the legislation can become law.
Strategy Resumes Bitcoin Purchases as MSTR Shares Fall
Saylor’s comments also follow Strategy’s return to Bitcoin purchases after an extended buying pause. Strategy acquired 4,603 BTC for roughly $369.7 million, with an average purchase price of $80,318. The purchase lifted the company’s Bitcoin holdings to 845,050 BTC.
Strategy has used Bitcoin as a central part of its corporate treasury strategy for several years. The company has continued accumulating BTC despite periods of sharp price swings across cryptocurrency markets. Moreover, its purchases have kept the company closely tied to Bitcoin’s market performance.
Despite the latest acquisition, Strategy shares have faced renewed selling pressure. MSTR recently fell about 4.2% to $138.74 as Bitcoin experienced fresh volatility after United States employment data. The shares remain down about 56% over the past 12 months, despite Strategy’s continued Bitcoin accumulation.
Now, hunting and other forms of recreation are permitted across a majority of those refuges when “compatible with each station’s purpose and mission under federal law,” per FWS.
The very definition of a refuge seems to have “slowly morphed into an entity that was meant to provide an opportunity for hunting access,” Williams says.
The new rule raises a question of compatibility: How can the refuges fulfill their conservation mandate amid the nation’s largest-ever expansion of hunting and fishing?
Does hunting undermine the purpose of a wildlife refuge?
The FWS said this week’s expansion is about “maximizing access where compatible with conservation goals.”
It also said that the new rule will help revitalize rural economies, as hunters and anglers contribute more than $144 billion annually to the U.S. economy.
“These activities support jobs, fund conservation efforts, and sustain outdoor traditions that connect communities to the land and to each other,” the August announcement read.
Pineapple Financial has moved more than $1 billion in residential mortgage records onto Injective, a layer-1 blockchain focused on financial applications, as part of a broader effort to migrate its historical loan portfolio onchain.
Pineapple plans to eventually migrate more than 29,000 funded mortgages worth over $10 billion onto the network, Injective said Friday. Each mortgage is represented by an onchain record tied to the underlying loan file, rather than being repackaged as a new mortgage security.
The records contain more than 500 data points, including loan-level information designed to support verification, audit trails and risk analysis. Pineapple’s dashboard shows that the migration now includes 2,079 mortgage records, up from 1,259 when the initiative launched in December 2025.
PAPL0, which tracks the mortgage records onchain, has an asset market cap of about $1.1 billion, up 48.2% over the past nine months, according to Token Terminal data. The tokens represent mortgage records rather than ownership of the underlying loans.

The mortgage migration is part of Pineapple’s broader relationship with Injective, which includes a separate $100 million Injective (INJ) digital asset treasury. Pineapple stakes INJ from the treasury, with Kraken serving as a primary validator for the holdings.

Real estate tokenization gains momentum
Real estate has become a growing focus of the push to bring traditionally illiquid assets onchain, where tokenization can make property or investment interests easier to divide, transfer and access.
In June, Apex Group joined Goldman Sachs, Archax and LRC Group on a tokenized real estate fund whose shares are issued as digital tokens through Goldman Sachs’ Digital Asset Platform. The structure gives investors blockchain-based ownership of fund shares, rather than simply recording property data onchain.
Dubai has also expanded its real estate tokenization efforts. In February, the Dubai Land Department launched the second phase of a pilot after about $5 million in property had been tokenized, with transactions recorded on the XRP Ledger.
However, tokenized real estate still remains a small part of the broader real-world asset (RWA) market. The sector has about $226.5 million in distributed value, up 11.7% over the past 30 days, compared with $38.8 billion across tokenized RWAs tracked by RWA.xyz.

This kind of change isn’t unique to real estate. It’s happening in education, finance, manufacturing, and virtually every other industry. No matter your profession, you may spend tremendous amounts of time on administrative work: writing spreadsheet formulas, analyzing documents, sending email, producing marketing content, organizing information, preparing presentations, and tackling repetitive tasks that add little strategic value.
What AI can’t replace
But whether you’re an attorney, consultant, plumber, financial advisor, or sales executive, your greatest value doesn’t come from routine administrative work. It comes from solving problems and building relationships.
Tools like ChatGPT, Claude, and Gemini can analyze contracts, create reports, summarize research, review documents, and automate a plethora of other tedious tasks. They allow professionals to spend less time on administration and more time serving their clients and building meaningful relationships. But AI isn’t replacing the qualities that matter most.
It doesn’t always look the way people expect, either. Sometimes, the moms who are suffering the most appear to have everything under control, says Jayme Scarfo, a licensed professional counselor in Surprise, Ariz., who specializes in working with pregnant and postpartum women. They’re showering, cooking, going to the gym, and insisting: “It’s hard, but don’t worry. I’ve got it.”
You don’t need to decide whether someone meets the diagnostic criteria before checking in. Describe what you’ve noticed without labeling her, Scarfo suggests: “I know this is a huge adjustment, and you haven’t seemed like yourself lately. How are you really doing?” Or: “You seem much more anxious than usual, and I’m worried about you. Can we talk about it?”
Consider who should initiate that conversation, too. “The best person to ask those hard questions is often going to be whoever she feels the least pressure to perform for,” Scarfo says. That might be a sister, best friend, therapist, or fellow mom—not necessarily her partner or mother.
The National Sheriffs’ Association (NSA) has dropped its opposition to a cryptocurrency market structure bill scheduled for a vote later this month when the US Senate returns to session.
In a Thursday letter to Senate Majority Leader John Thune and Minority Leader Chuck Schumer, the US law enforcement group said that it was changing its position on the Digital Asset Market Clarity (CLARITY) Act to “neutral.” The NSA cited the “significant work undertaken by Congress, the Administration, and stakeholders to navigate the many legal, regulatory, and enforcement considerations involved” in addressing the bill.
“At this time, we believe the most appropriate course is to step back and allow the legislative process to proceed to establish a clear, effective, and much needed regulatory framework,” said NSA president Troy Wellman and CEO and executive director Justin Smith.
The NSA previously expressed opposition to provisions in the CLARITY Act, saying it had “significant concerns” about amendments to exempt crypto mixers from many registration requirements. According to the group, the provision could “[impair] law enforcement’s ability to trace transactions and digital assets, and recover victims’ money.”
“The CLARITY Act protects the crypto industry, not the public,” said Sheriff Jim Skinner in a July video from the NSA.

Passed by the US House of Representatives in July 2025, the CLARITY Act has faced several hurdles since it was sent to the Senate for consideration. Although the Senate agriculture and banking committees passed their versions of the bill in 2026, many interest groups and lawmakers continue to raise concerns about aspects of the legislation, including stablecoin rewards, tokenized equities and potential conflicts of interest from President Donald Trump and his family.
Before breaking in August, Thune filed a motion to hold a cloture vote on the bill on Sept. 15 after senators return from state work periods.
US regulators to move forward without CLARITY?
In August, Trump stood alongside the heads of the US Securities and Exchange Commission (SEC), Commodity Futures Trading Commission (CFTC) and several digital asset companies to push for passage of CLARITY. SEC Chair Paul Atkins and CFTC Chair Michael Selig — both nominated by Trump — have signaled that their agencies would address crypto regulation if Congress were unable to pass the market structure bill.
Magazine: Token buybacks are booming. But are they good for crypto projects?
Post-quantum infrastructure company QuFi Network has launched a verification platform designed to protect digital assets against future quantum computing threats without requiring changes to existing blockchain settlement networks.
The platform separates verification from settlement, using a decentralized network of nodes to validate transactions with post-quantum cryptography before they are settled on existing blockchain networks.
QuFi also launched uBTC, a proof-of-concept that applies the verification system to Bitcoin (BTC) and is currently operating on Bitcoin Testnet4. The uBTC system verifies BTC collateral and generates cryptographic proofs governing how value moves between settlement environments, while redemptions ultimately settle as standard Bitcoin transactions.
The platform uses three post-quantum cryptographic standards — ML-DSA-65, SLH-DSA and ML-KEM-1024 — for digital signatures and secure key exchange.
QuFi said the external verification layer is intended to avoid the added storage, bandwidth and computing demands that can come with adopting larger post-quantum signatures directly on individual blockchains.
