Nhà phân tích Murphy đã đăng bài cho biết, khi giá BTC giảm, tính thanh khoản do các nhà tạo lập thị trường cung cấp sẽ tự nhiên nghiêng về phía Bid (mua vào), đồng thời các nhà giao dịch cũng sẽ đặt lệnh chờ ở mức giá thấp hơn để chờ nhận hàng. Dữ liệu cho thấy, độ sâu 5% của sổ lệnh giao ngay trên Binance đã đạt 80 triệu USD khi giá BTC giảm xuống khoảng 83,000 USD, theo mối quan hệ tương đối thì cao hơn so với giai đoạn điều chỉnh từ ngày 10 đến 16 tháng 9, gần với mức độ của giai đoạn tích lũy đáy BTC vào tháng 7.Tính toán ở mức 83,000 USD, khối lượng mua trong phạm vi độ sâu 5% ước tính phủ sóng đến 79,000 USD, có nghĩa là trong khoảng từ 83,000 đến 79,000 USD có một khối lượng đặt lệnh mua khá dày, có thể giảm thiểu rủi ro giá bị xuyên thủng nhanh chóng. Trong khi đó, chênh lệch giữa khối lượng mua chủ động và khối lượng bán chủ động trên Binance trong quá trình giá giảm liên tục tăng lên, cho thấy khối lượng mua chủ động gia tăng, khối lượng bán chủ động giảm. Murphy cho rằng, điều này cho thấy các nhà giao dịch không biểu hiện tâm lý bi quan rõ rệt, không chỉ khối lượng đặt lệnh mua thụ động ở phía dưới khá đầy đủ, mà ý chí mua chủ động trong quá trình giá giảm lại có phần tăng cường.

ChainCatcher tin tức, KOL Phyrex trong lĩnh vực tiền điện tử đã phân tích hệ thống phát hành rToken thuộc Bitget, cho rằng rToken không chỉ nên được hiểu là "cổ phiếu được mã hóa", giá trị cốt lõi của nó nằm ở việc kết nối với tài khoản thống nhất để đạt được khả năng kết hợp tài sản, phá vỡ giới hạn của các hòn đảo thanh khoản RWA.Phyrex đã phân tích ba chiến lược giao dịch có thể triển khai ngay: mở rộng vị thế hướng tới cổ phiếu Mỹ, chênh lệch Delta trung tính, và vòng quay cho vay thế chấp. Đối với các tổ chức, giá trị cốt lõi của rToken nằm ở ba cơ chế chính: kết nối trực tiếp với sổ đặt hàng cổ phiếu Mỹ để đạt được không có rủi ro tách rời, tài khoản thống nhất UTA kết hợp ký quỹ để nâng cao hiệu quả tài sản, và định giá tài sản thế chấp vào cuối tuần được neo theo giá đóng cửa thứ Sáu để kiểm soát rủi ro, cuối cùng đạt được quản lý vị thế Crypto, cổ phiếu mã hóa và sản phẩm phái sinh trong cùng một tài khoản, giảm chi phí điều chỉnh giữa các nền tảng và chuyển tiền.

Galaxy Research monitored that a physical Casascius Bitcoin minted between 2011 and 2013 (denomination of 25 BTC, approximately 1.78 million USD) had its private key extracted and completed an on-chain withdrawal.It is reported that Casascius Coin is an early physical collectible of Bitcoin, which contains real BTC private keys sealed inside. Holders can extract the assets after peeling off the anti-counterfeiting hologram sticker. This series was discontinued in 2013, and there are still tens of thousands of BTC sealed in unopened Casascius physical coins.

The court in Qujiang District, Quzhou City, Zhejiang Province, China recently ruled on a hacker case that used government and enterprise websites as a platform for pornography. The defendant, Zhou, illegally controlled over 150 servers (involving 157 government and enterprise units and well-known apps) through website vulnerabilities, batch-injecting malicious files, forcing redirection to overseas pornographic websites, and selling control permissions for profit. To evade tracking, Zhou rented a house and opened accounts using the identities of friends and relatives, arranged for accomplices to operate

According to CoinDesk, Solana's decentralized exchange Orca has launched a "permissioned pool" infrastructure aimed at tokenized trading of physical assets with high compliance requirements. The first participant is the commodity tokenization company Streamex, whose gold-linked security GLDY will become the first compliant token traded in this system.Orca stated that this mechanism is primarily aimed at the U.S. market, allowing only qualified investors who have passed KYC verification to buy, sell, and hold the relevant tokens. Issuers can customize access rules, which will be automatically enforced by the on-chain system. The permissioned pool operates on top of Orca's existing liquidity infrastructure, and the interface will indicate whether assets are restricted and whether users are eligible to trade.

Helio Protocol's XAUT gold stablecoin ecosystem has announced a strategic partnership with Dephy and APRO, aiming to jointly promote the application of AI intelligent quantitative systems in the fields of gold stablecoins, RWA (real-world assets on-chain), and DeFi.It is reported that this collaboration will be based on the Dephy Apro System AI quantitative architecture, combined with the on-chain asset clearing and cross-market liquidity management capabilities of the XAUT ecosystem, to construct a financial model of "AI + gold stablecoin + on-chain quantification." This model aims to achieve functions such as AI intelligent market prediction, automated on-chain quantitative trading, dynamic risk control, and intelligent adjustment of multi-market liquidity.In addition, according to official statistical data released, the average daily quantitative return rate of the XAUT AI Quant System reached 10.17% in the first quarter of 2026. In the future, the XAUT ecosystem plans to further promote the construction of infrastructure such as the AI-Agent automated trading system, cross-border payment network for gold stablecoins, and intelligent RWA clearing system.

On May 14, BNB Chain released the "BSC Post-Quantum Cryptography Migration Report," stating that it has completed the migration testing for quantum-resistant cryptography for transaction signatures and the consensus layer, using the NIST standardized post-quantum signature algorithm ML-DSA-44 (Dilithium) and the pqSTARK aggregation scheme.The report shows that BSC has replaced transaction signatures from ECDSA to ML-DSA-44 and switched consensus voting aggregation from BLS12-381 to pqSTARK to address the potential threats posed by future quantum computing to the existing elliptic curve cryptography system. However, post-quantum signatures also significantly increase the on-chain data volume: the size of a single transaction has increased from about 110 bytes to approximately 2.5KB; the block size in a 2000 TPS scenario has increased from about 130KB to around 2MB; and the TPS in the testing environment has decreased by about 40%-50%.BSC stated that the current network bottleneck mainly comes from the larger transaction data propagation, rather than the consensus protocol itself. Meanwhile, the consensus layer aggregation still maintains high efficiency, with pqSTARK achieving a signature compression ratio of about 43:1, and the additional burden on validators remains within a controllable range. The report concludes that existing technology can achieve "quantum-resistant" deployment for blockchain, but future issues related to network bandwidth and data scalability still need to be addressed.

NEAR Protocol stated on platform X that the team is adding post-quantum cryptography support for the network. NEAR's account model is different from Bitcoin and Ethereum; accounts are decoupled from cryptography and controlled through rotatable access keys.The NEAR One team is adding the NIST-approved lattice-based signature FIPS-204 scheme as the first post-quantum signature option. Once launched, any NEAR account holder can rotate keys through a single transaction, achieving quantum safety. NEAR is also collaborating with software and hardware wallets to advance post-quantum support.Through the chain signature feature, NEAR can provide threshold signatures for over 35 chains. The NEAR Intents team is developing a quantum-safe cross-chain signature solution. If other chains progress slowly in adopting post-quantum cryptography, NEAR can offer a quantum-safe environment. Aspects such as consensus mechanisms, validators, block synchronization, and transaction signatures also need to evolve for the post-quantum era, with the goal of achieving a one-time future-compatible migration.

According to Decrypt, Admiral Samuel Paparo, the commander of the U.S. Pacific Command, stated during a hearing before the U.S. House Armed Services Committee that the U.S. government is currently running a Bitcoin node for cybersecurity-related testing, but is not engaged in mining.Paparo indicated that the U.S. military's interest in Bitcoin primarily focuses on its value as a computer science tool, including cryptography, blockchain, and reusable proof-of-work mechanisms, with the aim of using the Bitcoin protocol to strengthen cybersecurity and enhance military capabilities, which is still in the experimental stage. He also mentioned that maintaining the global dominance of the U.S. dollar aligns with U.S. military interests and gave a positive evaluation of the stablecoin legalization bill, the GENIUS Act, signed by Trump last summer, believing that the bill helps to solidify the global position of the dollar.
