sign

Sign usually refers to digital signature technology in the fields of blockchain and cryptocurrency. A digital signature is a cryptographic technique used to verify the authenticity and integrity of digital information. It encrypts and decrypts data using public and private keys, ensuring that only users holding the private key can generate a valid signature, thereby providing authentication and data integrity assurance. Digital signatures play a key role in smart contracts, transaction verification, and identity authentication.

first_img The Solana Foundation launched Solana DvP, with JPMorgan participating in the design

According to Decrypt, the Solana Foundation announced the launch of the open-source custody program Solana DvP, providing standardized delivery versus payment (DvP) settlement APIs for financial institutions, released under the MIT license, with input from JPMorgan on the design of institutional settlement practices.The program aims to introduce settlement assurance into public chain infrastructure as a reusable standard, replacing the customized smart contracts previously relied upon by institutional trading.Solana DvP compresses the process that traditionally takes days to complete through clearinghouses, custodians, and custodians into a single atomic transaction, where assets and payments are settled simultaneously or not at all. The program supports SPL Tokens and Token-2022, covering extended features such as permanent delegation, pauseable tokens, and transfer hooks relied upon by regulated issuers, and has passed external security audits. The foundation stated plans to add privacy features in the future to keep settlement information confidential.Catherine Gu, head of digital asset products at the Solana Foundation, stated that atomic settlement eliminates the counterparty risk inherent in traditional finance, providing institutions with a single open standard to achieve finality in seconds rather than days.Rhodel D'souza, head of market digital assets at JPMorgan, said that the shared atomic delivery versus payment open standard is exactly the infrastructure needed by institutional market participants. This release builds on Solana's rising institutional appeal in the tokenized asset space, with BlackRock launching a tokenized money market fund in August, and Kraken offering tokenized U.S. stocks to overseas clients through its xStocks product on Solana.

first_img Energy developer FSE signed a memorandum with Loaf to plan a blockchain project for over 500 million dollars in photovoltaic energy

Energy developer Fusion Source Energy (FSE) and its partners have signed a memorandum of understanding with the on-chain physical asset platform Loaf to promote the issuance of over $500 million in Australian photovoltaic and battery projects on-chain, covering more than 1,000 hectares, led by the over 200 megawatt Project Amber. According to the memorandum, the funds raised are expected to accelerate project development and expand Amber's battery capacity.Amber is a utility-scale photovoltaic park that will deploy over 200 megawatts of photovoltaic and multi-hour battery storage on-site, with an expected annual power generation sufficient to meet the electricity needs of over 70,000 households, or equivalent to the electricity demand of a 50 megawatt data center. The project pipeline also includes battery storage assets below 5 megawatts and distributed energy resources, which are modular assets closer to the electricity end, capable of forming diversified energy revenue across multiple sites in Australia.FSE CEO Weiwei Shi stated that Amber is one of the largest hybrid on-site projects in the Southern Hemisphere, which have traditionally only been open to a few institutional investors. Loaf can expand the investor base without adding extra friction and provide continuous, transparent pricing for the assets.Loaf stated that Project Amber will become a key asset in its ecosystem. As the project matures and begins trading, users will be able to go long or short and use these assets within the on-chain financial ecosystem. Loaf will participate in the on-chain trading and issuance of physical assets, allowing users to access the economic upside and returns of related infrastructure assets.

first_img The United States has designated the Russian A7 Network as a transnational criminal organization and plans to cut off its cryptocurrency funding channels

According to Decrypt, the U.S. Department of the Treasury's Office of Foreign Assets Control has designated the Russian shadow banking network A7 Network as a significant transnational criminal organization, listing its relevant addresses in Russia, Kyrgyzstan, Nigeria, and Zimbabwe. The Financial Crimes Enforcement Network has proposed a draft rule that aims to prohibit U.S. institutions from participating in any fund transfers involving the network's "sub-agent companies," covering convertible virtual currencies and not limited to fiat currencies, which is expected to affect approximately 348,000 institutions, including several cryptocurrency exchanges.The proposal is based on six special measures granted by Section 9714 of the Countering Russian Money Laundering Act, ultimately selecting the sixth measure, which is the fund transfer ban. The fifth measure, which restricts correspondent accounts, is considered to have loopholes: research by blockchain intelligence firm TRM Labs shows that A7A5 transactions completely bypass the correspondent banking system, which the Financial Crimes Enforcement Network views as a core aspect of its business model. A7A5 is a ruble-backed token issued by Old Vector, registered in Kyrgyzstan, operating on Tron and Ethereum, with reserves held at the Russian state-owned defense bank Promsvyazbank.The Financial Crimes Enforcement Network stated that between February 2025 and June 2026, over 180 entities handled at least $17.91 billion in A7A5, which historically circulated almost entirely through the sanctioned exchanges Garantex and Grinex, often used as a non-frozen bridge to convert into USDT and then into fiat currency.

first_img New York and Wyoming regulators sign agreement to coordinate cryptocurrency regulation

According to Cointelegraph, the New York State Department of Financial Services (NYDFS) and the Wyoming Division of Banking announced the signing of a Memorandum of Understanding (MOU) to coordinate the regulation of cryptocurrency companies operating in both jurisdictions, covering license approvals, inspections, and potential enforcement actions. This agreement applies to businesses already regulated in either state, as well as companies seeking approval in both locations simultaneously.Under the agreement, the regulatory agencies in both states will share analytical results and historical inspection data to streamline the application process, coordinate inspection timelines, and promote joint inspections of companies operating across state lines. For businesses already regulated in one of the states, holding an existing license or charter for at least three years, and not subject to enforcement actions, the agreement provides an expedited approval pathway, with the second regulatory agency striving to make a decision within six months.The MOU also establishes a mechanism for sharing regulatory reports, market trend data, and notifications of potential enforcement actions, with regulatory agencies regularly sharing investigative information and being able to take joint, coordinated, or separate enforcement actions. This move connects two states that have historically taken different approaches to cryptocurrency regulation: New York has maintained the BitLicense regime since 2015, while Wyoming has accommodated digital asset businesses through cryptocurrency-related laws, regulations, and specialized banking charters.
