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 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.

first_img Satellite communication company Space Network signs a $50 million pre-purchase in the Philippines

Satellite communication infrastructure company Space Network has signed a binding pre-purchase agreement worth $50 million with Philippine infrastructure company HQ Company International Holdings to provide satellite connectivity to the Philippines through the low Earth orbit satellite network Freeport. The signing ceremony was held at SKY 31 in Seoul, attended by Space Network CEO Tae Lim Oh and HQ Company CEO Yongsoo Samuel Cho.According to the agreement, Space Network will provide access to the Freeport network, technical hardware, software, and ongoing engineering support, while HQ Company will be responsible for local sales, customer acquisition, spectrum authorization, and regional service implementation. Cho is the son-in-law of former Philippine President Fidel V. Ramos and has long been engaged in cross-border investment and infrastructure business in the Philippines. This agreement adds to the $100 million agreement signed by Space Network with Vietnam's DETI Technology in June 2026, bringing the total commercial pre-purchase amount to $150 million.Freeport is built and operated by Space Network, currently featuring 4 low Earth orbit satellites, with plans to expand to approximately 230 satellites by the time commercial services launch in 2029. Operators can purchase regional capacity and build their own services on the open network, with nodes settling through on-chain contracts. The related project Spacecoin combines blockchain protocols with low Earth orbit satellites for service pricing and payments within the network.

first_img SEC Commissioner Hester Peirce will resign on October 2

Hester Peirce, a commissioner of the U.S. Securities and Exchange Commission (SEC), announced she will resign on October 2. She published her resignation letter on social media platform X on Friday, revealing this date. Peirce is known in the industry as "Crypto Mom," having long advocated for clear rules for the crypto industry. During the tenures of Jay Clayton and Gary Gensler as chairmen, the SEC took a tough enforcement stance on crypto, while she continued to push for industry regulation. During the Trump administration, she was involved in rule-making and was appointed last year to lead the newly established SEC crypto working group.Her work in crypto encompasses policy statements and guidance on areas such as mining, staking, and meme coins, with the most important aspect being the classification and definition of various crypto assets to clarify regulatory jurisdiction. Recently, the SEC began proposing formal rules, the first being "Regulation Crypto Assets," which establishes a framework for issuing crypto assets that does not trigger strict securities regulation. The SEC also opened a path for tokenization of securities, known as "innovation exemptions," to initiate the era of securities tokenization with a five-year limited period.Peirce will become an associate professor at Regent University School of Law. After her departure, the SEC will have only two commissioners left, Atkins and Mark Uyeda, and the rules allow the two to constitute a quorum. On the same day, the SEC released a frequently asked questions document on crypto assets, addressing how to avoid triggering the "necessary managerial efforts" determination when marketing tokens, and discussing issues such as when staking receipt tokens and secondary markets are considered "promoters" of investment contracts.

Cosmos Hub: 1.227 million ATOM has been recovered from the Neutron attack case, with funds temporarily stored at a 4/6 multi-signature address

Cosmos Labs disclosed that on September 22, Neutron encountered a governance attack that led to the theft of liquidity from protocols such as Astroport, with approximately 1.73 million ATOM subsequently transferred by the attacker to Cosmos Hub. The Cosmos Hub itself was not attacked, and user funds were not affected. To prevent the stolen ATOM from being transferred out, Hub validators temporarily paused the network for about 24.5 hours and resumed block production on September 23 based on the patched Gaia v28.3.0.Cosmos Labs stated that during the pause, 1.227 million ATOM remained in the attacker's Hub address. When the network was restored, these were transferred to a 4/6 multi-signature address composed of Nansen, Keplr, Enigma, Silknodes, Kiln, and Polkachu through a one-time change. Previously, about 500,000 ATOM had been exchanged for ETH via THORChain and could not be recovered; another 169,000 ATOM entered the attacker's address after the network was restored due to THORChain refunds and were sold after being transferred to Osmosis. The current multi-signature address holds approximately 1.227 million ATOM, which can only be returned after authorization from a Cosmos Hub governance proposal. The related funds will not be staked, lent, or traded. The Neutron team expects to submit a recovery plan and related governance proposals next week.
