The SEC released a document (34-105260) disclosing the rule change application submitted by the NYSE, intending to formally introduce a framework for trading tokenized securities.According to the proposal, the NYSE plans to add Rule 7.5, allowing eligible securities to be traded and settled in a blockchain-based tokenized form in addition to traditional forms. The relevant arrangements will operate under the DTC pilot program. The core mechanisms include: tokenized securities and traditional stocks will share the same trading code (CUSIP) and rights structure, and will be fully interchangeable; in the matching system, tokenized and traditional securities will have the same execution priority, and the order of transactions will not be affected by the different forms; trading participants can choose to settle and clear in an on-chain form through a tokenization flag, with specific processing carried out by custodians. Additionally, the NYSE also plans to simultaneously modify order sorting, routing, and clearing rules to accommodate the trading process of tokenized securities, ensuring seamless integration with the existing market structure.From a market perspective, this proposal signifies that traditional U.S. securities exchanges are officially exploring the introduction of blockchain technology into the core trading and settlement systems. If approved, it could become an important milestone for on-chain securities entering mainstream financial infrastructure.

The National Police of Ukraine and the Internal Security Department conducted a joint operation, arresting a suspect in the Transcarpathian region who is alleged to be involved in an international cybercrime gang. This gang is implicated in fraud and money laundering cases exceeding $100 million targeting the United States and Europe, and had previously been listed as an international wanted person by the FBI.The suspect was found in possession of forged identity documents and had even fabricated a death certificate to conceal their whereabouts. The gang deployed malware to steal personal and corporate data, subsequently extorting victims for ransom. Money laundering methods included purchasing real estate and using relatives' names to obscure the flow of funds. Authorities seized approximately $11 million in assets, including cash, real estate, vehicles, and about $3 million worth of cryptocurrency, and also apprehended two co-defendants. The suspect faces charges of document forgery and money laundering.

According to official news, BitMEX Research has released a new research article proposing that in response to the risk of future quantum computers potentially breaking elliptic curve signatures, the Bitcoin network could adopt an alternative soft fork mechanism to "directly freeze" to reduce controversy and increase flexibility.The proposal revolves around "quantum-vulnerable fund freezing," but suggests avoiding the direct freezing of all related assets without evidence, instead gradually implementing security strategies through a verifiable condition-triggering mechanism. The core of the proposal is to establish a "signal vault," which contains special addresses generated using "accidental numbers" to prove that no one possesses their private keys. If passive spending occurs from that address, it will be regarded as on-chain evidence that quantum computing capabilities genuinely exist, thereby immediately triggering a comprehensive freeze of quantum-vulnerable assets.At the same time, the fund could attract capital through a multi-signature structure as a "quantum bounty," aimed at incentivizing potential attackers to expose their capabilities. The article also mentions that there is currently a BIP-361 proposal promoting the phased disabling of the old signature system and ultimately freezing risky assets, but this proposal is controversial due to its involvement in "mandatory freezing."The newly proposed "signal-trigger + security window" mechanism aims to replace the fixed-time freeze path, reducing potential system shocks while retaining Bitcoin's censorship-resistant characteristics, but it also brings complexity and execution risk trade-off issues.

According to market news, Circle has launched a new solution for high-frequency USDC payments across blockchains. Developers can use the Cross-Chain Transfer Protocol (CCTP) to have local fulfillers make advance payments on the recipient's designated chain, with the platform later completing cross-chain settlement.This model can reduce the operational burden caused by individual cross-chain transfers and is suitable for platforms that handle a large number of payments daily. Compared to the traditional CCTP process of destroying and minting USDC one by one, the new solution supports batch settlement, reduces the number of destructions on the source chain, and eliminates the need for signature infrastructure on the target chain. Circle also demonstrated the process based on the Arc Testnet and Ethereum Sepolia.

According to official news, the scalable blockchain network AO based on Arweave has announced the launch of the "Network Availability Staking Alpha (NASA)" testing program, which is a key step in its AO ecosystem aimed at enhancing the availability and reliability of decentralized data networks through a staking mechanism. The program is currently in the Alpha stage, and users can participate in network availability verification and earn rewards by providing data services for Arweave gateways and staking AO tokens.In the first pilot phase, AO introduces the "availability staking" mechanism, requiring node operators to stake 25 AO to participate in the network and compete for the speed and stability of responding to user requests. The system will allocate rewards from a monthly reward pool of 1000 AO based on the performance of nodes in data services. This mechanism relies on the next-generation HyperBEAM architecture, enabling higher levels of verifiability and trustlessness for gateway and routing services while significantly reducing operational costs.The project team stated that NASA aims to establish a stronger decentralized economic model for the entire permanent network infrastructure, paving the way for future expansion into areas such as computing scheduling, data indexing, and network services. Although the current reward scale is small and still in the testing phase, the program is seen as an important starting point for the AO-Core economic system and will gradually expand to more network infrastructure services in the future.

Anthropic has launched an authentication mechanism in some use cases of Claude to prevent abuse, enforce usage policies, and fulfill legal obligations. This process is supported by Persona, requiring users to submit a government-issued photo ID and possibly undergo real-time selfie verification.Anthropic states that the verification data is only used to confirm identity, not for model training, and will not be used for marketing or advertising. If verification fails, users can retry multiple times within the process or submit a form to request manual assistance. Accounts may be banned in cases of repeated violations of usage policies, terms of service, registration from unsupported regions, or use by individuals under 18 years of age.

The full-chain token issuance platform Printr announced the launch of the V2 upgrade, which introduces five new fee distribution models, including buyback and burn, liquidity compounding, POB staking, creator sharing, and zero-fee mode.Among them, the POB (Proof of Belief) mechanism allows users to share 100% of custom transaction fee earnings by staking tokens. V2 also launches configurable issuance parameters, automatic liquidity migration, and anti-copy protection features, and now supports 8 chains including Solana, Base, BNB Chain, and Ethereum.

Due to the migration of the top decentralized application Ether.fi to Optimism, the Ethereum Layer-2 network Scroll has experienced a significant loss of funds, resulting in a total value locked (TVL) decrease of approximately $160 million and an annual fee loss of about $13 million.Scroll stated that it will propose a plan to dissolve the decentralized security committee and reduce DAO members to lower operational costs, with network control being handed over to the internal team. Additionally, Scroll briefly raised network gas fees by 1,280 times after the protocol migration, causing users to pay over $50,000 in extra fees, but it has since returned to normal. After this adjustment, Scroll's TVL has dropped to approximately $23 million. The official statement claims that all contract changes will remain transparent and verifiable on-chain.

Hyperliquid founder Jeff announced in the Discord channel that the priority fee mechanism has now been launched on the mainnet in Alpha mode, including Gossip priority fees (used for prioritizing data reads) and Order priority fees (used for prioritizing order writes), for more details please refer to the official documentation.It is important to note that based on user feedback, the cap for order priority fees has been reduced from 20 bps to 8 bps. Currently, order priority fees are only applicable to IOC orders on HIP-3 assets.

The Bank of Korea stated that after the mispayment incident at Bithumb, careful consideration should be given to introducing a "circuit breaker" mechanism in the cryptocurrency market similar to that in traditional financial markets, to address extreme market volatility and systemic risks.The Bank of Korea pointed out that as the scale of the cryptocurrency market expands and related risks increase, existing regulatory measures are insufficient to fully cover potential issues. Therefore, it is necessary to study the introduction of protective mechanisms that can automatically interrupt trading to enhance market stability and investor protection. Previously, Bithumb experienced abnormal payments of some users' assets due to a system failure, which attracted market attention.

Bittensor co-founder Jacob Robert Steeves responded to the Covenant AI incident, stating that he was "deeply shocked" by the events of the past few days and accused Covenant AI founder Samuel Dare of causing serious harm to the protocol and community, betraying the trust of investors and users. He apologized to users who suffered losses due to the incident.Steeves stated that the original intention of Bittensor was to combat greed and selfishness in human nature, promoting AI to be collectively owned by all participants through a permissionless mechanism. He emphasized that while this incident exposed vulnerabilities in the system, it would also encourage the protocol and community to further enhance their risk resilience.Regarding future directions, Steeves proposed advancing the "Locked Stake" mechanism, introducing a "time + stake" commitment dimension at the protocol layer to improve transparency and investor protection, thereby reducing similar risks. He noted that this plan was originally designed with the participation of Samuel Dare.Additionally, he mentioned that the development related to subnets 3, 39, and 81 would continue to be driven by the community, and the overall functionality and vision would not change. Steeves emphasized that Bittensor remains one of the most decentralized AI protocols currently and will continue to promote the development of open AI, with plans to move towards training larger-scale models. In the future, they will train a 1 trillion parameter model.

Circle Chief Strategy Officer Dante Disparte published a response regarding the over $270 million theft incident involving Drift Protocol. Disparte stated that Circle only freezes USDC when legally mandated to do so, and this is not a unilateral decision, nor is it a backdoor or algorithmic monitoring. This reflects the rule of law in internet-native financial activities.He pointed out that the core issue facing open systems is that the legal framework's response speed lags behind technological development. Protocols, wallets, exchanges, and stablecoin issuers should regard security and accountability as a shared obligation, and DeFi protocols can develop on-chain technical protection measures by referencing the circuit breaker mechanisms of traditional markets.He also called for the legislative processes of the U.S. GENIUS Act and CLARITY Act to incorporate due process, property rights, and financial privacy protection standards into law before the next major security incident occurs.

Zhao Changpeng stated in an interview with TBPN that quantum computing could disrupt existing cryptocurrency mechanisms, and Bitcoin may need to fork to adopt quantum-resistant encryption technology. "Quantum computing may be able to break existing encryption mechanisms, but as quantum computing develops, new encryption algorithms will emerge. There are already quantum-resistant encryption algorithms, and quantum computers do not have an advantage in breaking these algorithms. Therefore, we just need to upgrade the protocol and adopt these encryption mechanisms."

The underlying financial infrastructure accelerating the birth of AGI, "B.AI," officially announced its launch today. In the moment when intelligence crosses the singularity, outdated financial barriers and physical limitations should not become AI's "digital cage." The imaginative space of AGI goes far beyond the laboratory; the real proposition is how to let AI break boundaries and benefit ordinary people.Tonight at 19:00 Beijing time, B.AI will fully reveal its technical details for the first time through X Space. Notably, Justin Sun will participate in the dialogue, returning to the underlying logic and deeply deconstructing how agents can autonomously take over economic behavior through "a line of code." This live broadcast will completely unveil the full picture of B.AI and discuss how intelligent agents can truly grasp economic sovereignty.Follow @BAI_AGI, retweet the post, and @ three friends for a chance to win a reward of 10 USDT.

The Bitcoin protocol Layer2 settlement network officially launched on April 6, achieving optimization and upgrades in on-chain data statistics and computing capabilities.In terms of technology, Layer2 supports deep cumulative calculations on-chain, which can more accurately reflect the on-chain team size and business data, improving processing efficiency in complex scenarios.In terms of governance, the protocol has transferred core permissions to a multi-signature contract, while adopting a dual-track governance model where developers and core community members each hold 50%, with an execution threshold of 65%, further enhancing decentralization.This upgrade completes the transition of the protocol to community autonomy, providing technical and governance references for the DeFi sector.

The Web3 asset data platform RootData issued a daily transparency alert on Twitter (X), noting the absence of information such as team details, key calendar events, and token data for projects like Sentism.AI, Fortune, Ultima, Etherex, and Solomon Labs. It calls on project teams to submit/update information on RootData to improve their transparency scores. Additionally, RootData stated that it will continue to monitor and expose "black box" projects that lack core information.It is reported that the RootData transparency score is used to measure a project's integrity and timeliness, aiming to reflect the project's information disclosure status, urging project teams to immediately claim their projects. The transparency score is categorized into five levels from A to F, with lower scores indicating more incomplete information disclosure and higher risks of malfeasance, requiring investors to exercise heightened caution.

The U.S. Department of Justice (DOJ) has expressed clear opposition to the latest request by Tornado Cash co-founder Roman Storm to dismiss criminal charges, stating that the recent Supreme Court ruling is unrelated to this case and should not serve as a basis for dismissal.Storm's attorney previously informed the court that he intends to cite a new Supreme Court ruling (involving a civil case of copyright infringement) to support the motion to dismiss. However, U.S. prosecutors pointed out in a letter to the federal judge that the ruling addresses a situation and industry completely different from the current criminal charges and therefore should not affect the handling of this case.This legal battle reflects the contradictory stance of the Trump administration towards the cryptocurrency sector: on one hand, the U.S. government has shown a relatively supportive policy inclination towards cryptocurrency, while on the other hand, it still insists on pursuing criminal liability against certain cryptocurrency project developers. Given the current situation, Storm may still face a retrial, and the case is expected to enter the courtroom again.
