According to Odaily, independent researcher Giancarlo Lelli was awarded the Q-Day Prize and 1 Bitcoin by quantum security startup Project Eleven for successfully cracking the encryption keys protecting Bitcoin. Giancarlo Lelli utilized publicly available quantum hardware and a variant of Shor's algorithm to crack a 15-bit encryption key among 32,767 possibilities. The difficulty of this quantum attack is 512 times greater than the 6-bit key record set in September 2025. Project Eleven CEO Alex Pruden stated that the resource requirements for such attacks continue to decline, with approximately 6.9 million Bitcoins currently held in vulnerable static addresses, including 1 million Bitcoins owned by Satoshi Nakamoto. The Bitcoin network has proposed BIP-360 to introduce quantum-resistant address types, while platforms such as Ethereum, Ripple, and Tron have also begun releasing plans for transitioning to post-quantum defenses.
Bitcoin developer Paul Sztorc has announced the official launch of the Bitcoin hard fork network eCash in August this year. BTC holders will be able to exchange BTC for eCash at a 1:1 ratio after the hard fork goes live. It is reported that the Layer1 node software of the network will be a "near copy" of the Bitcoin Core client, continuing to use the SHA-256 hashing algorithm, with a reduced initial mining difficulty to attract more miners to participate. Additionally, eCash will be equipped with seven Layer2 scaling networks called "drivechains" to increase transaction throughput and support optional on-chain privacy features.Paul Sztorc stated that eCash differs from Bitcoin Cash in 2017, as it will no longer use the "Bitcoin" branding, positioning it as a long-term solution to Bitcoin's scalability and privacy issues. However, his proposal to manually redistribute a portion of Satoshi Nakamoto's approximately 1.1 million BTC to early investors has sparked strong controversy within the community. Some Bitcoin supporters criticize the move as potentially constituting "theft" and undermining Bitcoin's principles. (Cointelegraph)
Bitdeer, a Nasdaq-listed Bitcoin mining company, posted its latest Bitcoin holdings data on X. For the week ending April 24, its Bitcoin mining output totaled 185.7 BTC, while it sold 185.7 BTC during the same period—resulting in a net addition of 0 BTC. It continues to hold zero Bitcoin.
Odaily BlockBeats News Tennessee Governor Bill Lee has signed a bill banning cryptocurrency ATM operations statewide, making Tennessee the second state to implement a complete ban after Indiana.The bill (HB 2505) has officially taken effect and will be enforced starting July 1. Under the new regulations, installing or operating a "virtual currency kiosk" (i.e., a Bitcoin ATM) will be classified as a Class A misdemeanor, punishable by up to one year in jail and a fine of $2,500. Additionally, merchants who allow such machines on their premises will also face legal liability.Currently, most U.S. states have strengthened oversight through measures such as licensing systems and transaction limits, but full bans remain rare. Data indicates that since 2026, 30 states have proposed related legislation, with 20 having passed laws, reflecting a continuous tightening of regulations around crypto ATM fraud risks.
According to The Block, OSL Group has announced a partnership with Circle’s affiliated entities to expand USDC integration across its payment and trading platforms. Through OSL Global, users can exchange USD for USDC at a 1:1 ratio and trade BTC, ETH, SOL, USD, and USDT pairs in a dedicated USDC trading zone. Meanwhile, OSL has adopted USDC as its unified margin asset and integrated USDC into its payment services to support compliant digital dollar settlement and payment use cases. OSL also stated that it plans to support Circle’s tokenized money market fund, USYC, subject to regulatory requirements and platform eligibility criteria.
According to the Belarusian state news agency BELTA, Alexander Yegorov, First Deputy Chairman of the National Bank of the Republic of Belarus, revealed at the “Digital Banking–2026” conference that Belarus has adopted Decree No. 19, formally establishing a regulatory framework for crypto banks. Under the decree, crypto banks will support 26 cryptocurrencies, including Bitcoin (BTC), Ethereum (ETH), TON (Toncoin), Solana (SOL), and multiple stablecoins. They will also be authorized to conduct 11 types of operations, such as crypto deposits, crypto lending, crypto staking, crypto collateralization, crypto transfers, issuance of proprietary tokens, and crypto storage and exchange. Yegorov stated that the current list of supported cryptocurrencies and permitted operations is not final and will be continuously updated and refined in response to investor demand and emerging ideas.
discussions regarding the potential threat of quantum computing to Bitcoin's security have been reignited. Analyst James Check points out that while quantum computing could theoretically crack elliptic curve signatures, its market impact may be overestimated.Data shows that approximately 1.7 million BTC (about $145 billion) are stored in early "Satoshi-era" addresses. If private keys were compromised, this could create potential selling pressure. However, from a market liquidity perspective, this scale is not insurmountable: in a bull market, long-term holders typically sell between 10,000 and 30,000 BTC daily. This means the aforementioned volume is equivalent to 2 to 3 months of routine profit-taking.Additionally, the average monthly exchange inflow is about 850,000 BTC, and the notional trading volume in the derivatives market can cover this amount within just a few days. Historical data shows that during the most recent bear market, over 2.3 million BTC changed hands in a single quarter, far exceeding the scale of the potential "quantum risk," yet it did not trigger a systemic collapse.Analysis suggests that even with a concentrated release, it is more likely to cause periodic volatility rather than a structural shock. Furthermore, entities capable of acquiring such assets are more inclined to adopt strategies like phased selling and hedging to mitigate market impact.Overall, the core issue of the "quantum threat" may not be the selling pressure itself, but rather the governance-level response—such as whether to restrict the movement of assets from affected addresses through a protocol upgrade.

According to CoinDesk, Input Output, the core development company behind Cardano, has submitted nine funding proposals totaling $46.8 million to the community treasury for fiscal year 2026—a sharp reduction of approximately 52% compared to last year’s $97.5 million—marking its first step toward gradually reducing reliance on community funds. The nine proposals center on two key initiatives: First, the Leios consensus upgrade, expected to boost Cardano’s transaction throughput by 10x to 65x and target over 1,000 transactions per second (TPS); testing is scheduled for June, with full deployment planned by year-end. Second, Pogun—a Bitcoin DeFi system enabling Bitcoin holders to borrow and earn yield via Cardano without entrusting assets to centralized custodians; its lending functionality is slated for public release in Q2. Voting is being conducted by roughly 1,000 democratically elected representatives (DReps), with ballots closing on May 24. The outcome will test whether the Cardano community now views Input Output as just another ordinary funding applicant. Meanwhile, Cardano’s newly launched stablecoin USDCx has achieved a circulating supply of 14.6 million tokens within weeks of launch, and the network’s total value locked (TVL) has risen from $137.5 million to $142.7 million.
According to Decrypt, American Bitcoin, a mining company affiliated with the Trump family, has deployed 11,298 Bitcoin miners at its Drumheller facility in Alberta, Canada, adding 3.05 EH/s of hash rate and bringing its total in-house hash rate to 28.1 EH/s across 89,242 devices. Following the announcement, ABTC’s stock rose over 13% during Wednesday’s pre-market trading. American Bitcoin stated that this deployment completes its previously announced expansion plan and that the average energy efficiency of its current in-house miners is 16.0 J/TH.
Odaily News Documentary Finding Satoshi was released on Wednesday, claiming that Bitcoin creator Satoshi Nakamoto is not an individual but a pseudonym jointly used by cryptographers Hal Finney and Len Sassaman. Directors Tucker Tooley and Matthew Miele, through a four-year investigation, pointed out that Hal Finney was responsible for writing the Bitcoin code, while Len Sassaman was responsible for writing the text content, including the whitepaper. Hal Finney's widow, Fran Finney, admitted in an interview that her husband may have been involved in the creation of Bitcoin. Investigators eliminated other candidates such as Adam Back through a process of elimination, noting that the online activity records of Hal Finney and Len Sassaman closely match those of Satoshi Nakamoto. Additionally, the film includes a 90-minute interview with Sam Bankman-Fried, but it was ultimately not used.
QCP released a market analysis stating that BTC rebounded from its overnight low near $75,000 to approximately $78,000; however, this rally appears more like a relief-driven correction following easing risk sentiment, rather than signaling the start of a new market phase. The report notes that Trump’s unilateral extension of the ceasefire with Iran has lowered near-term expectations of conflict escalation, yet the Strait of Hormuz remains largely closed and Iran’s stance remains unclear. Meanwhile, oil prices have held near $100 per barrel, resulting in concurrent inflationary pressures and slowing growth. QCP also points out that BTC open interest has risen noticeably while funding rates remain negative—indicating that short sellers are adding positions amid the rally. Overall, the options market continues to price in range-bound trading, not trend continuation.
According to the Financial Times, UK-based startup Stratiphy will offer both cryptocurrency exchange-traded notes (ETNs) and innovative finance ISAs (IF ISAs), enabling investors to hold crypto assets within capital gains tax-free accounts. Stratiphy provides three ETNs issued by 21Shares—the largest European crypto ETP issuer—which track Bitcoin, Ethereum, and a Bitcoin-and-gold composite product. The platform currently manages approximately £4 million in assets and serves around 2,000 clients. In October last year, the UK’s Financial Conduct Authority lifted its four-year ban on retail investors purchasing exchange-traded notes (ETNs).

Odaily News Etherealize has released its latest report, adjusting the long-term price expectation for Ethereum (ETH) to $250,000.This prediction is based on a core assumption: if ETH can capture a "monetary premium" similar to gold and Bitcoin, securing a place in the approximately $31 trillion store-of-value market, its price could reach this level.The report argues that ETH possesses unique historical attributes, serving not only as a store of value but also as a "yield-generating asset," distinguishing it from traditional asset forms.
Odaily News Kevin Warsh stated during a Senate hearing that digital assets "have become part of the U.S. financial system" and supports their inclusion into the financial system to provide investors with more opportunities and protection.This statement is seen as a signal of a generally more open policy towards the cryptocurrency industry should he become the Federal Reserve Chair. Warsh has previously referred to Bitcoin as an "important asset that aids in policy-making."However, Elizabeth Warren expressed concerns during the hearing, mentioning potential risks in the crypto space such as "sock puppet" accounts, emphasizing the need for enhanced regulation and prevention of abuse.
Odaily News A 50-page report commissioned by Coinbase indicates that although current quantum computers are not yet capable of cracking the encryption technologies of networks like Bitcoin and Ethereum, fault-tolerant large-scale quantum computers will eventually be built, and the crypto industry must begin preparations now. The report was authored by an independent advisory committee, including cryptographers and scholars such as Dan Boneh from Stanford University, Justin Drake from the Ethereum Foundation, and Sreeram Kannan from Eigen Labs.The report states that estimates for the time it would take quantum computers to break current encryption standards range from several years to over a decade. The U.S. National Institute of Standards and Technology recommends migrating to post-quantum cryptography by 2035, but the report suggests this timeline may be optimistic. Post-quantum cryptography already exists and is undergoing standardization, but post-quantum digital signatures can be tens to hundreds of times larger than existing signatures, potentially increasing block sizes by up to 38 times and introducing challenges such as wallet migration. The Ethereum Foundation has proposed a post-quantum digital signature scheme, and projects like Solana are also experimenting with post-quantum wallet designs. The report recommends adopting flexible transition strategies, such as hybrid systems, to prepare for future upgrades without compromising current security.
Coinbase’s Quantum Computing and Blockchain Independent Advisory Committee released its first position paper, stating that sufficiently powerful quantum computers could one day break the cryptographic mechanisms used by mainstream blockchains to protect digital assets—but such devices do not yet exist, and crypto assets remain secure for now. The industry should begin preparing for quantum-resistant upgrades immediately. The paper notes that Bitcoin mining, hash functions, and on-chain historical records currently face no material risk; the primary vulnerability lies at the wallet layer—in digital signatures. Ethereum has already proposed a relatively clear migration roadmap, while Solana, Algorand, and Aptos have either begun offering or are planning quantum-resistant solutions.

This collaboration connects fiat transfers, stablecoins, cryptocurrencies, and global payment networks within a single platform, simplifying cross-border payments, fund allocation, and treasury management processes. The two parties will also explore enabling merchants to accept cryptocurrency payments in the future.
According to Reuters, Greek maritime risk management company MARISKS has warned that some shipping companies stranded west of the Strait of Hormuz have received fraudulent messages impersonating Iranian authorities, demanding payment of a “transit permit fee” in Bitcoin or Tether (USDT). These messages are scams and not issued by official Iranian authorities. MARISKS stated that the scam messages claim documents must first be submitted and assessed by the “Iranian Security Department” before the cryptocurrency fee is determined. Currently, approximately hundreds of vessels and around 20,000 seafarers are stranded in the Gulf. During Iran’s brief opening of the Strait on April 18, at least two vessels—including one oil tanker—were forced to turn back after Iranian vessels opened fire on them.
On-chain investigator ZachXBT updated that funds related to the KelpDAO attack have begun moving: approximately $1.5 million has been cross-chained from Ethereum Mainnet to the Bitcoin network via Thorchain, and roughly $78,000 has been transferred via Umbra. The attacking address initially sourced its funds from Tornado Cash, and fund laundering and cross-chain transfers are ongoing.
