One of the Bitcoin contributors, Jameson Loop, along with other cryptographers, has proposed an initiative that may force Bitcoin holders to migrate their tokens to new quantum-resistant addresses, or else their tokens will be permanently frozen by the network itself. In this scenario, holders technically still own these coins but will lose the ability to transfer them. This is known as Bitcoin Improvement Proposal BIP-361, which was updated on Tuesday in Bitcoin's official proposal repository, titled "Post-Quantum Migration and Old Signature Retirement."BIP-361 builds on the BIP-360 proposal introduced in February. BIP-360 introduced a soft fork (a type of network upgrade) aimed at enabling a new transaction type called "Pay to Merkle Root" (P2MR). This approach draws on Bitcoin's Taproot (P2TR) framework but removes key-based spending paths, thereby eliminating an element widely considered to pose risks in the quantum era.The BIP-361 proposal divides the migration into three phases. Phase A starts three years after activation and prohibits anyone from sending new bitcoins to old, quantum-vulnerable addresses. You can still spend from these addresses, but you cannot receive any coins. Phase B starts five years after activation and will render old signatures (ECDSA and Schnorr) completely ineffective, with the network rejecting any attempts to spend coins from quantum-vulnerable wallets.Essentially, your coins will be frozen. Finally, there is Phase C, which is a rescue plan still under research: holders of frozen wallets may potentially prove ownership through zero-knowledge proofs (a method of proving knowledge of a secret without revealing the secret itself). If successful, the coins frozen in Phase B can be recovered.

X product head and Solana advisor Nikita Bier stated that during this round of creator revenue sharing, the revenue share for all aggregated accounts has been reduced to 60%. In the next cycle, it will be further reduced by 20%. Nikita Bier pointed out that the large amount of plagiarized reposts and clickbait content published daily on the timeline not only squeezes the living space of real creators but also hinders the growth of new authors. The next step will be to permanently deduct earnings from users who habitually post clickbait content and use the "BREAKING" label in every post. X will not restrict speech or the scope of dissemination but will not provide revenue compensation for manipulating distribution mechanisms or misleading user behavior.

Binance announced its participation in the international law enforcement operation "Operation Atlantic," led by the UK's National Crime Agency (NCA), in collaboration with multiple countries' law enforcement agencies to combat cryptocurrency and investment fraud, focusing on "approval phishing" scams.The operation was jointly initiated by the NCA, the U.S. Secret Service, and relevant law enforcement and regulatory agencies in Ontario, Canada, aiming to identify victims who have been compromised or are at risk. Approval phishing typically disguises itself as an investment opportunity, luring users into granting wallet access permissions, thereby transferring assets. During the operation, Binance's special investigation team provided on-site support in London, including fraud identification processes, risk screening, and intelligence analysis, and assisted in identifying potential victims and related malicious websites.At the same time, Binance also provided law enforcement agencies with addresses and suspect intelligence related to the case, supporting asset tracking and enforcement actions. The NCA stated that this operation has successfully protected thousands of potential victims in the UK and overseas. Binance emphasized that it will continue to cooperate with global law enforcement agencies to strengthen the fight against cryptocurrency fraud.

According to CoinDesk, the Financial Services Commission of South Korea and the Financial Supervisory Service jointly issued new regulations requiring all domestic cryptocurrency exchanges to adopt a unified withdrawal delay review standard to curb voice phishing scams.The new regulations eliminate the authority of each exchange to set its own withdrawal exemption conditions, and reviews will be conducted uniformly based on standards such as account history, trading patterns, and behavioral anomalies. It is expected that less than 1% of users will qualify for instant withdrawals. Platforms must also enhance identity verification and fund flow monitoring.Previously, scam groups exploited the exemption rules of various platforms to guide victims to convert cash into cryptocurrency and complete withdrawals within minutes. This new regulation marks a shift in South Korea's cryptocurrency risk control system from industry self-regulation to a national unified standard.

The U.S. Securities and Exchange Commission (SEC) is making significant adjustments to its enforcement strategy in the cryptocurrency sector for the fiscal year 2025. The SEC has successively withdrawn seven cryptocurrency-related enforcement actions initiated by the previous commission, involving institutions such as Coinbase, Binance, Kraken, Cumberland DRW, Consensys, Dragonchain, and Balina, on the grounds that these cases lack sufficient federal securities law basis.At the same time, the SEC has established a Cyber and Emerging Technologies Division, focusing on combating violations of securities trading related to blockchain technology, artificial intelligence, and cybersecurity. In terms of specific enforcement actions, the SEC has filed lawsuits against the following cases: New York cryptocurrency company Unicoin and its four executives for allegedly making false statements to mislead investors; PGI Global founder Ramil Palafox for allegedly orchestrating a cryptocurrency and forex fraud scheme amounting to $198 million and misappropriating over $57 million; and the founder of AI company Nate, Inc. for allegedly raising over $42 million illegally through false advertising of artificial intelligence capabilities.

Brazilian President Lula has signed Law No. 15,358, which explicitly incorporates seized cryptocurrency assets during law enforcement into the public safety funding system for expenditures such as police equipment, intelligence operations, and personnel training.The law allows for the temporary use of relevant cryptocurrency assets prior to final conviction with court approval. The new regulations also significantly expand the powers of judicial authorities, allowing them to freeze, block, or confiscate cryptocurrency assets during the investigation phase, including restricting access to exchange accounts, digital wallets, and related platforms. Once convicted, the individuals involved will be permanently deprived of the ability to use the formal financial system and cryptocurrency systems. Additionally, the law categorizes the use of encrypted communication tools or privacy technologies to conceal criminal activities as an aggravating circumstance, promotes cross-border asset recovery and intelligence sharing, and establishes a national database to integrate the financial structures of criminal organizations. Analysts believe that this initiative marks Brazil's shift of cryptocurrency assets from potential reserve tools to law enforcement resources, strengthening the crackdown on organized crime (such as PCC and Comando Vermelho) while advancing the judicial system's regulatory and disposal capabilities regarding digital assets.

Lombard and Bitwise Asset Management announced a partnership at the Digital Asset Summit in New York, offering a solution for institutions to earn yields and collateralize BTC lending without moving assets out of custody, targeting the scale of BTC assets under institutional custody.Bitwise will develop yield strategies that combine DeFi lending with tokenized real-world assets, while the decentralized lending protocol Morpho will provide the infrastructure for BTC collateralized lending. The platform uses Bitcoin-native tools such as partially signed transactions and time locks to verify collateral, allowing positions to be represented on-chain without transferring or re-collateralizing the underlying assets.Phillips stated that Bitcoin Smart Accounts can simultaneously reduce custody, cross-chain bridge, and counterparty risks. This solution is aimed at high-net-worth individuals, asset management firms, and corporate treasuries, with plans to launch in the second quarter of 2026 and will add more custodians and protocols to expand coverage.Lombard estimates that approximately $500 billion in BTC is under institutional custody; DefiLlama data shows that the total locked value of BTC in DeFi is about $2.93 billion, with a market cap of approximately $1.4 trillion; as of the time of writing, Babylon Protocol's total locked value is about $2.8 billion, and Lombard's is approximately $744 million.

According to New Daily, the Financial Supervisory Service (FSS) of South Korea, the Customs Service, the Credit Finance Association, and nine credit card companies in the country signed the "Public-Private Cooperation Agreement to Block Transnational Criminal Funding" on the same day. The plan aims to cut off the funding chain for telephone fraud and virtual asset crimes at the source by analyzing overseas credit card usage details and entry and exit records.In the past, due to information gaps between agencies, the Customs Service had entry and exit data but could not monitor abnormal overseas consumption in real-time, while credit card companies had payment data but did not have access to cardholders' customs clearance dynamics. Under the new mechanism, the Customs Service will provide credit card companies with information on high-risk transaction trends, while the Financial Supervisory Service will establish guidelines authorizing credit card companies to take effective measures such as interrupting transactions when abnormalities are detected.Lee Chan-jin, the head of the Financial Supervisory Service of South Korea, stated that this move signifies that South Korea has established a normalized monitoring system to block the outflow of criminal proceeds at the source. The system will focus on precisely targeting currency exchange behaviors that involve cash withdrawals at overseas ATMs using overseas credit cards and laundering through cryptocurrencies.

According to Decrypt, the U.S. Secret Service will collaborate with the UK's National Crime Agency, the Ontario Provincial Police, and the Ontario Securities Commission, among other agencies, to launch an international joint operation called "Operation Atlantic," aimed at combating cryptocurrency scams such as "authorized phishing" or "pig butchering."

According to CoinDesk, law enforcement agencies from the United States, the United Kingdom, and Canada have jointly launched a multinational operation called "Operation Atlantic," focusing on combating "approval-phishing" scams targeting cryptocurrency users.The Ontario Securities Commission stated that these scams typically use pop-ups and prompts disguised as trustworthy applications or services to guide users into authorizing malicious wallet permissions. Once authorized, attackers can control the wallet and transfer assets. Data shows that cryptocurrency scams are expected to generate at least approximately $14 billion in on-chain illegal revenue by 2025, with the total scale potentially approaching $17 billion as more involved wallets are identified.Law enforcement agencies pointed out that current scam activities increasingly rely on social engineering, AI-generated content, and "Phishing-as-a-Service" platforms. The operation is being coordinated by multiple national law enforcement agencies, and regulators stated that the new initiative will help identify victim wallets, timely warn potential victims, and attempt to track and freeze stolen cryptocurrency assets to reduce the space for criminals to profit further.
