Abstract

Ripple's XRP Ledger (XRPL) has achieved a significant milestone by developing a fully quantum-resistant testnet, a feat not yet accomplished by Bitcoin. Developers, including validator Vet and XRPL Labs engineer Dennis Angell, revealed that the AlphaNet testnet now features quantum-secure consensus, accounts, transactions, and Dilithium cryptography. While this advancement enhances security, it comes with trade-offs, such as larger transaction signature sizes. The move addresses growing concerns about quantum computing risks to blockchain networks relying on ECDSA cryptography, which could be vulnerable to powerful quantum computers. This proactive approach positions XRPL ahead of competitors, ensuring long-term infrastructure resilience and a smooth transition to post-quantum security.

Developers on Ripple’s XRP Ledger (XRPL) have revealed progress on making the network quantum-resistant. This comes as some Bitcoin advocates and developers downplay the imminent risk posed by quantum computing, stating that it is unlikely to be a concern anytime soon.

Ripple’s XRP Ledger Works On Quantum-Resistant Code

In an X post, Ripple’s XRP Ledger validator Vet revealed that developers are already working on quantum-resistant code on the network. This came as he drew attention to a fully quantum-proof XRPL, including consensus, which is currently in testnet. This marks progress for the network, even as it achieves something that networks like Bitcoin still lag on.

Vet indicated that creating a quantum-proof XRP Ledger is likely to come with some disadvantages for the network. He stated that one of the downsides of these encryptions is the size of the signatures. He shared a video showing that transaction signatures for payment on the quantum XRPL are much longer than on the XRPL mainnet.

Vet’s post followed the revelation by XRPL Labs engineer Dennis Angell that the AlphaNet, the developer network for XRPL, is now fully quantum-secure. Angell mentioned that the testnet now has quantum consensus, quantum accounts, quantum transactions, and dilithium cryptography. He further remarked that they had added native smart contracts while declaring that the quantum-resistant future of blockchain is live.

Notably, this move comes as Ripple and the XRP Ledger look to onboard more institutions onto the network. Concerns about quantum computing are on the rise, with Bitcoin in the spotlight at the moment, as developers have yet to make meaningful progress on making the flagship crypto quantum-resistant.

Following the XRP Ledger’s progress on making the network quantum-resistant, crypto pundit Jenna questioned the possibility of Bitcoin investors selling their BTC because it’s not quantum-resistant and then buying XRP because it is safer. Another pundit, Mickle, also noted how the XRP Ledger is already pretty much quantum-proof while Bitcoiners argue over whether quantum computing is real or not.

Why Working Towards Quantum-Resistant Transactions Matters

In an X post, crypto pundit Sandip noted that blockchains such as Bitcoin, XRP Ledger, and Ethereum rely on ECDSA cryptography. This puts them at risk, as a sufficiently powerful quantum computer could theoretically break them in the future. He then remarked that testing this early ensures the network is future-proofed against the time when quantum computers become powerful enough to break these networks.

Meanwhile, Sandip explained that these XRP Ledger developers are testing optional and upgradeable signature schemes. This will ensure that wallets and validators can later support post-quantum keys. It also enables a smooth migration before quantum risk becomes real. The pundit added that this is long-term infrastructure planning, not price manipulation, as it puts the XRPL ahead of many competitors, including Bitcoin.

Venture capitalist Nic Carter, who has been very vocal about the quantum risk to Bitcoin, has explained why it is important to start preparing against this risk from now. He highlighted how there are several decisions to be made and processes to be taken if developers are to successfully make the flagship crypto quantum-resistant.

TechFlow Intelligence Agency: Anthropic Calls for Global Pause in AI Development While Preparing for Trillion-Dollar IPO; SpaceX IPO Roadshow Heats Up, But S&P 500 Rejects Fast-Track Inclusion

In today's TechFlow Intelligence Briefing, several major tech stories highlight a growing theme of trust and credibility gaps across AI, crypto, and finance. AI company Anthropic has publicly called for a global pause in AI development, citing risks from Claude's "recursive self-improvement." Ironically, this coincides with reports the company is preparing for a massive IPO targeting a near $1 trillion valuation. This perceived hypocrisy, coupled with widespread user complaints about Claude's declining performance, is sparking debate over whether the safety warning is genuine or a competitive tactic. Meanwhile, in a substantive security move, Anthropic open-sourced a framework for AI-powered vulnerability discovery. In the crypto market, Bitcoin's price drop below $61,000 triggered over $1.16 billion in liquidations, flipping the market into a state where more BTC is held at a loss than at a profit, a historical bearish signal. On the corporate front, SpaceX's highly anticipated IPO is generating immense Wall Street excitement, with Goldman Sachs projecting 100x revenue growth by 2030. However, the S&P 500 has refused to fast-track the company's inclusion post-IPO, potentially limiting immediate institutional demand. Separately, ByteDance's AI app Doubao lost over 6 million monthly active users after introducing a subscription model, highlighting the challenges of AI monetization. Other notable developments include Nvidia certifying HBM4 memory from Samsung, SK Hynix, and Micron; Cloudflare's acquisition of front-end tooling company VoidZero; and its CEO warning that bot traffic now exceeds human traffic online. The underlying narrative connects these events: a trust crisis. From AI firms' contradictory actions and crypto volatility to the clash between SpaceX's hyped narrative and institutional rules, a pattern is emerging where stated intentions and actual practices are increasingly misaligned.

Dalio Warns: AI Boom Shows Signs of a Bubble, Day of Reckoning Will Be the Time of Burst

Ray Dalio, founder of Bridgewater Associates, warns that the current artificial intelligence investment boom shows classic signs of a bubble, which he expects will eventually burst. In a Bloomberg Television interview, he noted that great technological revolutions often lead to capital inflows that create bubbles, making it difficult for investors and companies to calibrate their spending accurately—either overspending to capture market share or underspending and losing their competitive position. This caution comes amid significant rallies in AI-related assets, particularly chipmakers, driven by soaring demand for data centers and high-bandwidth chips, raising debates about overheating valuations. In contrast, Nvidia CEO Jensen Huang recently asserted that investors embracing the AI wave would see "crazy" returns and dismissed concerns over return on investment for data center spending as outdated. Dalio, however, focuses on the risks in the profit realization phase. He argues that bubbles tend to show signs of破裂 when markets transition from investment to the need for tangible returns, describing the burst as a process of converting paper wealth into cash. While acknowledging AI's intrinsic value, he expressed concern over the future profitability of some AI companies, suggesting the market is repeating a familiar pattern. The 76-year-old billionaire, who fully exited Bridgewater in 2025, has a net worth estimated at $21.5 billion according to the Bloomberg Billionaires Index.

Privacy Coin Crisis of Confidence! ZEC Plunges Over 56% in a Single Day

Zcash (ZEC), a leading privacy-focused cryptocurrency, experienced a severe crash on June 5th, plummeting over 56% in a single day and erasing nearly two months of gains. The flash crash was triggered by the disclosure of a critical zero-knowledge proof vulnerability within Zcash's Orchard privacy pool, which had existed since the pool's launch in May 2022. The flaw theoretically allowed an attacker to forge unlimited ZEC undetectably due to the pool's privacy features. The vulnerability was discovered on May 29th by independent security researcher Taylor Hornby during a proactive audit commissioned by Shielded Labs, utilizing AI-assisted analysis. The Zcash development team responded swiftly, implementing an emergency soft fork to disable Orchard transactions on June 2nd and executing a permanent hard fork fix (NU6.2) on June 3rd. Despite the technical fix, a major crisis of confidence emerged. The core issue is that Orchard's privacy design makes it cryptographically impossible to prove whether the vulnerability was exploited over the past four years, casting permanent doubt on the historical supply integrity of ZEC. While Shielded Labs argues exploitation was unlikely, the inability to provide definitive proof has severely damaged market trust. This sentiment was exacerbated when BitMEX co-founder Arthur Hayes, a prominent ZEC supporter, announced he was selling his entire position. He stated that privacy assets require "perfect security" rather than "probable safety." The combined effect of the disclosure and Hayes's exit ignited widespread panic selling, leading to massive liquidations and significant price decline. Analysts note the event highlights a fundamental tension within privacy coins: the conflict between verifiable supply and cryptographic privacy.

Bitcoin Demand Falls At Fastest Pace Since LUNA Collapse: Data

On-chain data indicates that Bitcoin's total demand has sharply declined over the past month, contracting at its fastest rate since the collapse of the Terra/LUNA ecosystem in May 2022. This "demand" metric, tracking the combined flow of Bitcoin into spot and derivatives markets, has recently plummeted to a 30-day negative change of 501,000 BTC. Analysts note the recent price surge in April and early May was driven solely by speculative futures demand, while spot demand contracted—a pattern historically unsustainable for rallies. With both spot and futures demand now shrinking, the pace of contraction echoes the post-LUNA collapse period. Concurrently, Bitcoin's price has dropped to around $63,200, its lowest level since February.

Bitcoin Falls To $61,300 As Mt. Gox Moves BTC, Raising Selloff Concerns

Bitcoin fell to around $61,300 as markets reacted to Mt. Gox moving funds, raising selloff concerns. The defunct exchange transferred 116.3 BTC (worth ~$8.16 million) directly to Bitstamp, following a larger earlier move of 10,422.65 BTC (~$739 million) to a new wallet. The trustee is working towards the final creditor repayment deadline of October 31, 2026. While most eligible creditors have been repaid, roughly 24,081 BTC (~$1.55 billion) remains under Mt. Gox control, and its on-chain movements are closely watched for potential market pressure. Bitcoin later recovered above $64,000.
