Bittensor co-founder Const (@const_reborn) responded on Twitter to recent allegations regarding Covenant AI. Const stated that he has no authority to pause emissions, and that the previous sale of a portion of alpha positions in three subnetworks was because these subnetworks were not operational and were in a high ratio of code destruction state. The impact of this transaction on emissions is consistent with the buying and selling behavior of ordinary TAO holders, and he does not enjoy any special privileges.Regarding management authority, Const clarified that it was Samuel himself who abandoned his Discord channel, and he did not remove his administrator role; he only temporarily restricted his ability to delete posts that honestly criticize and then restored it. Additionally, he emphasized that the scale of the token sell-off was less than 1% of his total investment in the team, and stated that exercising the rights to buy and sell tokens under the dTao system is fundamental to supporting the operation of the system.According to previous reports from ChainCatcher, the main subnetwork developer on Bittensor, Covenant AI, announced its withdrawal from Bittensor. Covenant AI founder Sam Dare stated that the reason Bittensor attracts builders, miners, validators, and investors into this ecosystem is because of its promise not to be controlled by any single entity. But this promise is a lie.

According to Jinshi Data, the number of initial jobless claims in the United States for the week ending April 4 was 219,000, expected to be 210,000, and the previous value was revised from 202,000 to 203,000.

AI company Anthropic announced that starting from April 4 at 15:00 Eastern Time, it will prohibit access to third-party tools through the Claude subscription service, including the open-source project OpenClaw. The new regulations require that related features can only be used through additional packages or billed on a pay-as-you-go basis via API.This adjustment means that many developers and teams relying on OpenClaw to build automated workflows will shift from a fixed subscription cost model to an unlimited pay-as-you-go system, significantly increasing overall usage costs. Some developers have indicated that the original usage cost of about $20/month could soar to hundreds or even thousands of dollars.The market generally believes that this move is related to OpenClaw founder Peter Steinberger's recent joining of OpenAI. Meanwhile, Anthropic is accelerating the promotion of its own tool ecosystem, including native integration solutions for Claude, to replace third-party toolchains.It is worth noting that Anthropic has previously tightened third-party access through technical restrictions, updates to service terms, and feature replacements. This policy is seen as a "final blockade" and will be extended to more tools.Industry analysis points out that this event reflects an intensifying trend of "ecosystem tightening" in AI platforms, with leading companies strengthening control through vertical integration. At the same time, the developer ecosystem faces rising cost uncertainties and platform dependency risks, which may further drive some users toward more open alternatives.

According to Decrypt, the U.S. Attorney's Office for the District of Connecticut announced that it has recovered and seized over $600,000 in cryptocurrency after a Ledger hardware wallet user fell victim to a phishing scam, being lured into performing a so-called security check by a letter impersonating "Ledger Security and Compliance," resulting in approximately $234,000 in crypto assets being stolen.The FBI and state police tracked the flow of funds, successfully seizing about $600,000 in USDT and filing a civil forfeiture lawsuit, alleging that the source of the funds involved wire fraud and money laundering. It is reported that this is one of a series of phishing incidents targeting hardware wallet users, where scammers used physical mail letters featuring company logos, holograms, and QR codes to enhance the credibility of the fraud. Similar incidents have affected companies like Ledger and Trezor, accompanied by data breaches and vulnerabilities in third-party services, leading to ongoing phishing attacks.

According to Greekwire, Washington State Attorney General Nick Brown has filed a civil lawsuit against the prediction market platform Kalshi, accusing it of violating state betting and consumer protection laws by offering betting services on events such as sports, elections, and wars. The lawsuit has been submitted to the King County Superior Court, seeking to prohibit Kalshi from operating locally, recover lost funds for residents, and impose civil fines. Kalshi's advertisements have suggested that users could bypass local laws to participate in NFL betting, indicating that they "knowingly violated the law."However, Kalshi responded by stating that it is a compliant trading platform regulated by federal authorities, denying the provision of war-related markets, and expressing confidence in winning the case legally. This is reportedly another regulatory action the company is facing recently, as it is currently involved in over 20 civil lawsuits. Previously, prosecutors in Arizona had filed criminal charges against it, which is considered the first criminal case against a prediction market.

The Secretary for Financial Services and the Treasury of Hong Kong, Xu Zhengyu, introduced the development of stablecoins and digital renminbi in Hong Kong, stating:The People's Bank of China and the Hong Kong Monetary Authority are working closely together to optimize the arrangements for digital renminbi. Currently, the number of mainland operating institutions responsible for operating digital wallets has increased from four to five, while the number of local Hong Kong banks participating in the "Faster Payment System" for digital wallets has increased from 17 to 18. The number and usage of digital wallets opened with Hong Kong mobile numbers have shown stable growth.According to the People's Bank of China, as of the end of January 2026, approximately 80,000 digital wallets have been registered. The Hong Kong Monetary Authority and local banks have been actively promoting the application of digital renminbi in Hong Kong. Currently, the number of local merchant retail points accepting digital renminbi has increased from about 300 to approximately 5,200, covering chain retail stores, hotels, travel agencies, restaurants, convenience stores, and supermarkets.The People's Bank of China and the Hong Kong Monetary Authority are exploring the arrangements and feasibility for upgrading digital wallets to increase their usage limits, expand application scenarios, and enhance user experience. As the policies and technical details involved still require in-depth discussion, specific plans and timelines are yet to be finalized.Stablecoins and central bank digital currencies (such as digital renminbi), as well as other new payment tools, including tokenized deposits and cross-border connections for rapid payment systems, have the potential to be applied in transaction settlements, local or cross-border payments, and other scenarios, provided they comply with relevant legal and regulatory requirements.These payment tools each have their own characteristics and varying degrees of maturity, and their future development prospects are largely determined by market forces. The government and financial regulatory agencies will continue to explore the potential and application scenarios of various new payment tools, better leveraging their synergies to address more pain points in the real economy.

According to market news, two legislators in Delaware have proposed the Delaware Banking Modernization Act (Senate Bill 16) and the Delaware Payment Stablecoin Act (Senate Bill 19), aimed at establishing a licensing framework for stablecoin issuers.The Stablecoin Act intends to implement licensing management for stablecoin issuers and digital asset service providers operating in Delaware, adopting relevant definitions and statements from the U.S. federal Stablecoin Act (GENIUS Act), and setting regulatory requirements such as reserve shortfall remediation mechanisms, mandatory redemption time limits, capital requirements, and anti-money laundering obligations. If approved, the state banking commissioner will be responsible for implementing the relevant rules within the specified timeframe. The Banking Modernization Act primarily updates corporate governance for traditional financial institutions while introducing a definition of digital assets to enhance regulatory certainty. Both bills still need to be reviewed by the Senate Banking Committee and debated by the full Senate.Delaware Governor Matt Meyer stated that this legislation aims to attract future industries and provide residents with more convenient financial services.

According to U.Today, the Bitcoin network experienced a rare two-block reorganization last night. At height 941880, the network briefly split into two competing chains. AntPool mined block 941881, and ViaBTC subsequently mined block 941882 on the same chain; meanwhile, Foundry USA mined its version of block 941881 and continued to mine its version of block 941882. After Foundry USA continued to mine blocks 941883, 941884, and 941885, the competing chain was broken, and the blocks from AntPool and ViaBTC were discarded as orphan blocks.This reorganization was not an attack or a failure, but rather a normal result of Bitcoin's decentralized consensus mechanism. Single-block reorganizations occur from time to time, but two-block reorganizations are relatively rare, indicating that the tie between the two chains lasted for an entire block cycle. Foundry USA mined seven consecutive blocks from 941879 to 941885.
