Solana's official article on the potential impact of quantum computing on blockchain reiterates that the quantum threat is still years away, but the Solana ecosystem has already conducted thorough research and technical preparations in advance.The independent verification client development teams Anza and Firedancer (which together represent a large portion of the network's staking share) have unanimously concluded after independent research that a compact signature scheme suitable for high-throughput blockchains is needed, and they have jointly selected the Falcon scheme. Both parties have published their initial implementation code on GitHub.In addition, the Solana Winternitz Vault developed by Blueshift has been operational in the ecosystem for over two years, providing a direct quantum-resistant path. Earlier this year, Google Quantum AI listed this Vault as a leading example of forward-looking post-quantum work in its white paper.Solana's current quantum roadmap includes ongoing quantum research and evaluation of Falcon and alternative solutions; adopting post-quantum solutions for new wallets when quantum becomes a credible threat; and migrating existing wallets to the selected solution. The official statement indicates that the migration work is manageable and can be completed quickly when the time comes, with network performance expected to remain largely unaffected.

CryptoQuant analyst Darkfost posted on the X platform that Binance attracted a total of $6 billion in stablecoin inflows in March and April, with nearly $3.5 billion in net inflows in April, contrasting sharply with the previous net outflow of about $7.6 billion.Despite the escalating tensions between the U.S. and Iran increasing market uncertainty and concerns about rising inflation being unfavorable for risk assets, the trend of stablecoin inflows has clearly shifted. The analyst pointed out that when inflows to major exchanges exceed outflows, it indicates that some parts of the market are beginning to reposition themselves to participate in the gradual recovery over the past two months. If this trend continues, it may provide support for a short-term positive market.

A whale placed two limit buy orders, one for 397.769 BTC and the other for 397.718 BTC, totaling approximately 795.49 BTC, with a limit price of 77686.5 USD, for a total value of about 61.77 million USD.

CryptoQuant CEO Ki Young Ju stated that the recent rise in Bitcoin is mainly driven by the futures market, while on-chain spot demand remains negative.He pointed out that, based on historical experience, bear markets typically require a synchronized recovery of both spot and futures demand to potentially end.

According to Onchain Lens monitoring, after 3 years of silence, a giant whale deposited all 2301 ETH (5.5 million USD) into Kraken.

According to official news, Four Pillars announced that it has obtained Series A financing from Pantera Capital and Further Ventures, with the specific amount undisclosed.It will transition from a previous research institution to a blockchain research and infrastructure provider aimed at institutional users. It is reported that in the three years since its establishment, Four Pillars has collaborated with over 100 protocols and companies, releasing more than 600 research reports. In the future, it will focus on three main directions: FP Research (divided into five specialized departments: crypto, investment, institutions, Asia, and technology), FP Validated (institutional-level validator infrastructure providing staking services), and FP Institution (a newly established institutional department offering seminars and consulting services).

According to on-chain analyst Yu Jin's monitoring, the whale pension-usdt.eth shorted $110 million worth of BTC and ETH at the price bottom with 3x leverage at the beginning of the month, and subsequently, in April, the price rebounded, resulting in an unrealized loss of $15.25 million on the short position.Shorting 1,000 BTC at $67,992, currently facing an unrealized loss of $10.57 million, with a liquidation price at $99,394; shorting 20,000 ETH at $2,132, currently facing an unrealized loss of $4.68 million, with a liquidation price at $3,400.

CryptoQuant analyst Axel Adler stated that after the release of market pressure in the spring, the selling pressure from short-term holders (STH) has significantly eased. The Bitcoin market repair is still ongoing, and the current price is close to the cost line of short-term holders. The key trigger for the subsequent trend lies in whether it can effectively stabilize above the short-term holder cost basis of about $83,000. Only by breaking through and stabilizing above this level can the market further validate the actual selling pressure strength of short-term holders and whether it will suppress the price drop again.

According to Jinshi reports, after the shooting incident at the White House Correspondents' Dinner, when asked if he was worried about facing a threat to his life, U.S. President Trump said, "This (presidency) is a dangerous profession." However, he stated that he did not want to live in fear.He also joked that if his Secretary of State Rubio had told him in advance about the risk of violence, he might not have run for president.

According to Onchain Lens monitoring, a certain wallet spent $7 million to buy 3,017 ETH after being dormant for 1.6 years, with an average purchase price of $2,320.In the past two days, this whale has purchased a total of 7,300 ETH, worth $17 million, and there may be further accumulation actions to follow.

According to CoinDesk, while quantum computers cannot disrupt the Bitcoin mining mechanism or the blockchain ledger, they may potentially crack the elliptic curve encryption system that protects wallet ownership through Shor's algorithm. Currently, about 6.9 million BTC (approximately one-third of the total supply) face potential risks due to public keys being visible on-chain, including around 1 million early holdings by Satoshi Nakamoto; transactions generated after the Taproot upgrade in 2021 are also affected due to public key exposure.Ethereum has established a formal quantum resistance migration plan since 2018, with 4 full-time teams and over 10 independent development groups, and has launched a dedicated progress website at pq.ethereum.org. In contrast, Bitcoin currently lacks a unified response roadmap, and the existing BIP-360 proposal and BitMEX Research detection scheme have not received widespread support from core developers. Notable Bitcoin advocate Nic Carter pointed out that Bitcoin's response is "the worst," while Blockstream CEO Adam Back believes that current quantum systems are still in the laboratory stage, but he also agrees that optional upgrade solutions should be deployed in advance.Analysts point out that Bitcoin's anti-centralization governance culture makes coordinating large-scale security upgrades extremely difficult, and how to handle historical legacy issues such as Satoshi Nakamoto's holdings is particularly challenging. A related paper from Google warns that once quantum attacks become a reality, the window for response may have already closed.

Two whale wallets have recently withdrawn a large amount of $LINK from Binance. Wallet "0x527" withdrew 370,631 $LINK (approximately 3.48 million USD) and currently holds 565,612 $LINK (approximately 5.33 million USD); wallet "0x526" withdrew 125,999 $LINK (approximately 1.19 million USD).

Project Eleven today awarded the Q-Day prize to researcher Giancarlo Lelli, who successfully derived a 15-digit elliptic curve private key from a public key using publicly accessible quantum hardware, marking the largest scale demonstration of its kind to date, a 512-fold increase from the 6-digit demonstration in September 2025.Lelli used a variant of Shor's algorithm for the elliptic curve discrete logarithm problem, which is the mathematical foundation of the Bitcoin signature scheme, with the awarded hardware featuring approximately 70 qubits. Currently, no known quantum computer can crack real Bitcoin wallets, and the security of Bitcoin's 256-bit elliptic curve remains far beyond current quantum capabilities. Notably, Google lowered its resource estimates for ECDLP-256 on March 31 and set a target for the migration to quantum cryptography after 2029, followed by Cloudflare, and the UK's NCSC also set migration milestones from 2028 to 2035.On-chain data shows that approximately 6.93 million BTC are at potential quantum risk due to exposed public keys. The Bitcoin community has proposed BIP 360 and BIP 361 to promote the migration to quantum-resistant output types, but the coordination challenges of a decentralized network remain the biggest hurdle.

According to market news, Colombia and U.S. law enforcement agencies have jointly acted to successfully dismantle a transnational cryptocurrency money laundering network associated with the Mexican "Jalisco New Generation Cartel" (CJNG). Since 2023, this network has transferred over $190 million in illegal funds through cryptocurrency channels, seizing multiple crypto wallets and cash on site.Investigations show that the network commonly employs tactics such as fund splitting, decentralized transfers across multiple wallets, circulation across jurisdictions, and token swaps to evade tracking. Currently, authorities have not disclosed specific details regarding the cryptocurrencies involved, trading platforms, or the number of arrests, and the investigation is still ongoing.

The French National Anti-Organized Crime Prosecutor's Office (Pnaco) has stated that cases of kidnapping and illegal detention involving cryptocurrency are continuing to surge. Among the 12 related cases currently under investigation, 88 people have been prosecuted, including more than 10 minors, and another 75 are in custody awaiting trial.Prosecutor's data shows that since 2023, French law enforcement has recorded 135 such cases, with 18 in 2024, rising to 67 in 2025, and reaching 47 so far in 2026. Many of these cases involve violent kidnappings, ransom extortion, and forcing victims to transfer cryptocurrency assets. The prosecution pointed out that some suspects have appeared multiple times in different cases, indicating the formation of a structured criminal network behind it. The previous kidnapping incident involving Ledger co-founder David Balland is also seen as an important sign of the escalating security risks in the French cryptocurrency industry.

According to market news, SpaceX is expected to go public in June, potentially surpassing Saudi Aramco's $29 billion fundraising record to become the largest IPO in history. Meanwhile, OpenAI and Anthropic also plan to go public in the second half of this year, with the three companies expected to collectively attract over $240 billion in funding, likely marking a significant turning point for liquidity changes in the cryptocurrency market.Market analysis suggests that these super IPOs may significantly withdraw liquidity from risk assets, while the cryptocurrency market is in the same pool of funds. As mainstream cryptocurrencies like Bitcoin and Ethereum have been highly correlated with Nasdaq and U.S. stock market risk appetite in recent years, a large amount of capital shifting towards subscribing to tech giants' IPOs may weaken the buying support for BTC, ETH, and altcoins.

According to The Information, Anthropic and OpenAI have both experienced security incidents, raising market concerns about the safety of AI models themselves.Currently, Anthropic is investigating potential unauthorized access to its Claude Mythos model by users. Almost simultaneously, OpenAI was also reported to have accidentally exposed several unreleased models in its Codex application. Industry opinions indicate that these vulnerability incidents have intensified scrutiny on the security governance capabilities of AI companies and reflect that the security systems of current AI technology still need improvement as it rapidly develops. Analysts believe that even AI model providers that focus on cybersecurity capabilities face significant security challenges themselves. As AI is gradually used to defend against cyberattacks, issues related to platform security and access control have also become critical risk points.

According to Cointelegraph, local police in Spain seized two cryptocurrency cold wallets containing approximately 400,000 euros (about 467,000 dollars) in assets during an operation against illegal comic distribution platforms.The operation was carried out by the Almería police in Spain, who have arrested three suspects and dismantled what is known as the country's largest Spanish-language piracy comic website. It is reported that the platform has been providing free pirated content since 2014, primarily profiting through advertisements, with total revenue exceeding 4 million euros over the past decade. Notably, the cold wallets involved were hidden inside a thermometer in the wall. The police have not yet disclosed whether they have obtained the relevant private keys or access to the funds.

Market news: Google plans to invest up to $40 billion in Anthropic.
