ZK Tools Are Quantum Immune

ZK Tools Are Quantum Immune

study producing major crypto privacy news found that zero-knowledge proof systems including Railgun, PrivacyPools, Aleo, and Aztec are mathematically immune to quantum attacks, because they rely on information-theoretic security rather than encryption, meaning they remain safe even against infinitely powerful attackers including future quantum computers.

Summary

  • The Coinbase-led study, co-authored with Stanford and Ethereum Foundation researchers, found that ZK proof systems derive their security from how information is structured and shared.
  • Bitcoin wallets with exposed public keys remain the most immediately vulnerable category in any quantum attack scenario, while ZK-based privacy tools are unaffected by the same class of attack.
  • The finding provides a concrete security advantage for privacy-preserving DeFi infrastructure at a moment when the broader crypto industry is still debating how and when to implement post quantum cryptography across base-layer networks.

Crypto privacy news arrived Tuesday with a significant finding: the same quantum computing threat that has triggered emergency roadmaps at Ripple, Bitcoin, and Ethereum appears not to apply to privacy-preserving zero-knowledge proof systems. A study co-authored by Coinbase researchers alongside teams at Stanford and the Ethereum Foundation concluded that networks like Railgun and PrivacyPools rely on a fundamentally different security model than the one quantum computers are designed to attack.

The study was shared with DL News and concludes that zero-knowledge proof systems “rely on information-theoretic systems which are secure even against infinitely powerful attackers because of how information is structured and shared, not because of encryption.” That distinction is not a matter of degree. It is a categorical difference between computational security and information-theoretic security.

Why Zero-Knowledge Proofs Are Structurally Immune

Standard blockchain security, including the protection on Bitcoin wallets and Ethereum accounts, relies on computational hardness: the assumption that breaking the underlying math problem requires more computation than any attacker possesses. Quantum computers using Shor’s algorithm can in theory solve certain categories of these math problems exponentially faster than classical computers, which is why Bitcoin’s elliptic curve signatures are considered potentially vulnerable.

Zero-knowledge proofs work differently. They allow one party to prove knowledge of a secret without revealing the secret itself, and the security guarantee comes from information-theoretic principles rather than computational difficulty. Even a computer with infinite processing power cannot extract more information than the proof was designed to reveal. That structural property makes ZK-based privacy tools immune to Shor’s algorithm and to any quantum attack that targets computational hardness.

What This Means for Railgun, Aztec, Aleo, and PrivacyPools

Railgun is a privacy protocol that shields transaction amounts and addresses using ZK proofs on Ethereum. PrivacyPools is a protocol designed to allow compliant privacy by letting users prove their funds do not come from sanctioned sources without revealing their full transaction history. Aleo is a Layer 1 blockchain built natively around ZK proofs. Aztec is an Ethereum Layer 2 with private smart contract execution via ZK proofs.

All four rely on information-theoretic security for their core privacy guarantees. The Coinbase study’s conclusion means that when quantum computers eventually mature to the point of threatening Bitcoin’s key security, the privacy properties of these networks will remain intact. Their vulnerability, if any, would come from other components of their architecture, such as the underlying elliptic curve signatures used for account authentication, which is a separate security layer from the ZK proof system itself.

The Broader Implication for DeFi Privacy Infrastructure

The finding arrives as the broader Bitcoin quantum risk debate is producing governance friction across the ecosystem. The quantum threat debate in Bitcoin has centered on whether to force coin migration or rely on optional upgrades. ZK-based privacy infrastructure sidesteps that debate entirely, because its core security model was already quantum-immune by design.

For DeFi developers and institutional users evaluating infrastructure choices over long time horizons, the study provides a concrete basis for treating ZK-based privacy tools as categorically more future-proof than traditional transparency-based blockchain accounts with respect to the quantum threat. Ethereum co-founder Vitalik Buterin has publicly endorsed protocols like Railgun on broader grounds, arguing that privacy should be a default option for blockchain users. The quantum immunity finding adds a security dimension to that argument.

Bipartisan PACE Act Targets Cheaper Payments for Fintechs and Crypto Firms

Bipartisan PACE Act Targets Cheaper Payments for Fintechs and Crypto Firms

US Reps. Young Kim (R-CA) and Sam Liccardo (D-CA) introduced the bipartisan Payments Access and Consumer Efficiency (PACE) Act on Tuesday, proposing a federal framework that would give fintechs and crypto companies direct access to Federal Reserve payment rails.

The bill targets a longstanding bottleneck in US payments. Currently, only legacy banks can connect directly to the Fed’s clearing and settlement systems, charging nonbank providers markups of up to 100 times the Fed’s own per-item fee, according to the bill’s fact sheet.

What the PACE Act Would Change

Under the proposed law, qualified nonbank payment companies could register for an optional federal supervisory framework administered by the Office of the Comptroller of the Currency (OCC).

Registered providers would gain access to Fedwire, FedNow, and FedACH.

The bill requires providers to maintain 1:1 reserves in safe, liquid assets and meet risk management and recordkeeping standards.

It also aligns with the “skinny master accounts” concept championed by Federal Reserve Governor Christopher Waller.

Crypto exchange Kraken became the first digital asset firm to receive such an account earlier in March.

The measure arrives alongside other pro-crypto legislative efforts, including the GENIUS Act for stablecoins.

However, the PACE Act focuses narrowly on payment infrastructure rather than market structure or token classification.

“We can reduce the burden of bank fees borne by too many American families by enabling broader access to innovative payment systems that deliver cheaper, faster, more reliable service,” Eleanor Terrett reported, citing Rep. Sam Liccardo.

Industry Groups Rally Behind the Bill

The Blockchain Association, Crypto Council for Innovation, Financial Technology Association, and the Digital Chamber all endorsed the PACE Act.

Blockchain Association CEO Summer Mersinger called it an “important step forward,” noting that digital asset payment companies have long been “locked out” of financial infrastructure available to competitors.

The bill now heads to committee, where traditional banking lobbies may push back against provisions that reduce their role as intermediaries in payments.

Kalshi Ventures Into Cryptocurrency Derivatives With Perpetual Futures Trading

Published

on

Brian Armstrong's Bold Prediction: AI Agents Will Soon Dominate Global Financial

Key Highlights

  • Platform transitions from prediction markets to continuous crypto derivatives trading

  • Regulated perpetual futures set for April 27 rollout with USD collateral

  • Monthly trading volumes surpassed $1 billion mark in March 2025

  • Stablecoin collateral integration planned for Q2 following initial launch

  • Strategic positioning against established players like Coinbase and Binance

Kalshi is set to enter the cryptocurrency derivatives arena with a regulated perpetual futures offering scheduled for April 27. This strategic expansion represents a significant departure from the platform’s traditional event-driven contract model, introducing continuous trading instruments linked to digital asset valuations. The initiative enables Kalshi to directly challenge incumbent crypto exchanges while capitalizing on its compliant operational framework.

Platform Diversification Through Derivative Instruments

The upcoming launch introduces perpetual futures contracts that provide price exposure to cryptocurrencies without predetermined settlement dates. Unlike conventional event-based markets that conclude upon specific outcomes, these instruments facilitate ongoing position management. Consequently, this product evolution significantly enhances Kalshi’s trading infrastructure and market relevance.

These derivative contracts utilize funding rate mechanisms to synchronize contract valuations with underlying spot market prices continuously. This technical framework enables Kalshi to deliver stable pricing dynamics alongside adaptable trading parameters. Additionally, the perpetual structure accommodates extended investment horizons beyond what binary outcome markets traditionally provide.

Initial trading will utilize U.S. dollar denominated collateral requirements. Subsequently, Kalshi has outlined intentions to integrate stablecoin collateral options during the second quarter. This phased implementation strategy permits methodical expansion while adhering to regulatory compliance standards.

Expanding Digital Asset Trading Momentum

Cryptocurrency-related trading activity on Kalshi has demonstrated substantial acceleration throughout recent periods. March 2025 marked a milestone achievement with monthly transaction volumes crossing the one billion dollar threshold initially. This performance trajectory validates considerable market appetite and reinforces the strategic rationale for derivatives expansion.

Perpetual futures contracts currently constitute the dominant segment of worldwide cryptocurrency trading volume, particularly across offshore exchange venues. Nevertheless, regulated access within United States markets remains constrained, presenting a strategic opening for Kalshi. The platform can effectively capture traders prioritizing compliant pathways to crypto derivative exposure.

Beyond digital currencies, the company envisions extending its perpetual futures framework into commodities and additional asset categories. This comprehensive development timeline reflects broader strategic ambitions consistent with multi-asset platform evolution. Through this approach, Kalshi reinforces its competitive positioning for sustained market participation.

Competitive Landscape And Sector Dynamics

This strategic expansion positions Kalshi in direct rivalry with major platforms including Coinbase Global and Binance. These established exchanges currently provide cryptocurrency trading services, encompassing derivative products across various regulatory jurisdictions. Kalshi’s distinguishing characteristic stems from its comprehensive U.S. regulatory oversight structure.

The prediction markets sector has witnessed explosive expansion, with transactional activity achieving unprecedented benchmarks throughout 2026. This industry momentum reinforces Kalshi’s integrated approach merging prediction market infrastructure with perpetual futures execution. This hybrid architecture enables more effective liquidity aggregation and capital efficiency.

The platform has secured substantial capital backing, achieving multi-billion dollar valuation metrics. Industry intelligence indicates potential plans for a public market debut within an approximate two-year timeframe. These developments underscore Kalshi’s ongoing operational scaling efforts concurrent with strategic entry into additional financial product categories.

No Talks Under Threats, Tehran Says

Published

Iran strikes Gulf energy network as oil surges past $110

Iran war news escalated Tuesday as parliament speaker Mohammad Bagher Ghalibaf stated publicly that Tehran will not accept negotiations under conditions it considers coercive, with the 10-day US-Iran ceasefire set to expire Wednesday and both sides sharpening rhetoric ahead of prospective talks in Islamabad.

Summary

  • Ghalibaf warned that Iran has spent the past two weeks preparing “new cards on the battlefield” and accused Trump of violating the ceasefire by maintaining the naval blockade and seeking Iran’s surrender.
  • Iran’s foreign ministry said it has no plans for a second round of negotiations, while IRIB cited Iranian sources confirming no decision has been made to participate in Islamabad talks.
  • Trump told CNBC he is “ready to go” back to war if no deal is reached and said he would not extend the ceasefire, while also saying he expects a “great deal” and that Iran has “no choice.”

Iran war news turned sharply negative Tuesday as Iranian officials delivered a unified message hours before the US negotiating team led by Vice President JD Vance was expected to arrive in Islamabad. Tehran’s position, as expressed through multiple official channels, is that it will not enter talks while the US naval blockade of its ports continues and while American officials publicly threaten expanded military strikes.

“We do not accept negotiations under the shadow of threats, and in the past two weeks, we have prepared to reveal new cards on the battlefield,” Ghalibaf wrote on X. He accused Trump of using the ceasefire period to seek Iran’s surrender rather than a genuine agreement, calling the US posture “warmongering.”

Iran’s foreign ministry spokesperson Esmaeil Baqaei confirmed at a weekly press briefing that “as of now, we have no plans for the next round of negotiation, and no decision has been made in this regard.”

Why Tehran Is Holding Its Position

The core Iranian complaint is structural. The US imposed a naval blockade of Iranian ports on the same day the ceasefire was announced, treating it as a tool of coercion rather than a genuine pause in hostilities. Iran has maintained since Sunday that continuing participation in any talks depends on the US changing its behavior, specifically lifting the blockade and stopping what Tehran describes as ceasefire violations.

Iranian President Massoud Pezeshkian separately criticized US officials for sending “unconstructive and contradictory signals,” noting that Trump publicly claimed Iran had agreed to give up its enriched uranium stockpile while Iran denied this within hours of the claim. The gap between what each side says the other agreed to is itself a structural obstacle to building the trust necessary for second-round talks.

The Hormuz Situation and What Happens at Midnight

The ceasefire expires Wednesday. The Strait of Hormuz, which Iran briefly reopened before closing again after the Touska cargo ship seizure, remains effectively closed to normal traffic. Iran sent drones toward US military ships after the Touska was boarded by US forces, signaling that its military posture remains active. The USS Gerald R. Ford carrier operates in the Mediterranean while the USS Abraham Lincoln is in the north Arabian Sea, with a third carrier group expected in the region by month’s end.

Trump told CNBC he is “ready to go” if talks fail and said he would not be rushed. He also said Iran has “no choice” but to negotiate. The contradiction between those statements and Iran’s stated refusal to talk under threat defines the standoff heading into the Wednesday deadline.

What This Means for Oil and Crypto Markets

The ceasefire hopes that lifted Bitcoin to $72,700 and pushed oil down 13% on April 8 are now at direct risk. A resumption of hostilities at midnight Wednesday would push Brent crude above $100 again and remove the macro tailwind that has supported crypto markets over the past two weeks. The oil price channel into inflation expectations, Fed rate policy, and risk asset positioning means that the outcome of Wednesday’s deadline is the single largest near-term variable for Bitcoin and the broader crypto market.

One-Third of EU Investors May Switch Banks Due to Crypto Interest: Survey

One-Third of EU Investors May Switch Banks Due to Crypto Interest: Survey

Cryptocurrency offerings are starting to influence how European investors are choosing their bank providers, but regulatory uncertainty continues to hinder mainstream adoption, according to a new survey.

A Börse Stuttgart Digital survey released Tuesday found that 35% of European investors would consider switching banks if another institution offered better cryptocurrency investment options, suggesting crypto is starting to influence how some customers choose financial providers.

Nearly one in five respondents said they expect their main bank to offer crypto access within the next three years, according to the survey, which covered about 6,000 investors in Germany, Italy, Spain and France. The findings suggest crypto is moving closer to the mainstream banking relationship, at least among investors already open to digital assets.

Still, regulations and a lack of education remain the biggest hurdles to adoption, with 76% seeing crypto assets as insufficiently regulated, while over 60% feel poorly informed about digital assets.

MiCA increased trust in digital assets for nearly half of European investors

European Union regulation appears to be helping on that front. The EU’s Markets in Crypto-Assets Regulation (MiCA) went into full effect for crypto asset service providers on Dec. 30, 2024.

Nearly half of the surveyed investors said that the MiCA framework increased their trust in digital assets, making them “safer and more attractive.”

“Trust and clear regulation are essential for the next phase of crypto adoption in Europe. With MiCAR bringing transparency and legal certainty, investors gain the clarity they expect,” said Matthias Voelkel, the CEO of Börse Stuttgart Group.

The results land as traditional financial institutions across Europe keep inching deeper into crypto. Börse Stuttgart Digital said in January 2025 that it had become the first German provider of crypto asset services to receive an EU-wide MiCA license through its custody subsidiary, positioning itself as a regulated infrastructure provider for banks, brokers and asset managers.

Spain leads European crypto adoption

Among the surveyed countries, Spain showed the highest crypto adoption rate with nearly 28% of investors already owning digital assets. Germany was second with 25%, Italy followed with 24% and France with 23%.

Of the respondents, 25% said they had already invested in crypto, and 36% said they are likely to invest again within the next five years, showing “sustained interest despite market volatility,” according to the report.
