Researcher Dan Robinson from Paradigm proposed a new scheme called PACT (Verifiable Address Controlled Timestamp), aimed at protecting long-dormant bitcoins, including Satoshi's early addresses, from future quantum computing attacks.This mechanism allows users to prove their control over an address through a timestamp without the need to transfer assets or expose on-chain behavior. Once future quantum attacks occur, assets can be recovered in a quantum-resistant version of the Bitcoin network based on that proof. Compared to mandatory migration schemes (like BIP-361), PACT avoids the privacy exposure issues caused by actively transferring assets, providing long-term holders with a more flexible preemptive protection path.

ChainCatcher news, Nansen CEO Alex Svanevik posted on the X platform stating that the initial feedback from using the AI Research Agent suggested that Sun Yuchen was conducting a WLFI sell-off, but upon further inspection of the WLFI transaction timestamps, it was found that Sun Yuchen did not engage in a market dump.Additionally, Alex Svanevik pointed out that the related transfers occurred after a significant drop in WLFI, so they were not the main cause of the price decline. Moreover, based on the trading volume proportion across the network that day, it may not have had a substantial impact on the market price trend.

ChainCatcher news, according to Cointelegraph, Timestamp has announced the launch of a crowdfunding platform in the United States specifically aimed at Bitcoin startups, designed to connect crypto projects with new funding channels.According to the company, investors will receive ownership shares in the supported companies, similar to traditional equity investments. Timestamp CEO Arman Meguerian stated, "This structure provides investors with real equity while ensuring complete regulatory compliance." Projects can initially "soft launch" through activity pages to generate early interest. Once the legal paperwork is completed, they can be fully publicly launched.Crowdfunding, especially involving stock issuance, is regulated by the U.S. SEC. According to public records, Timestamp has been registered with the agency since October 2023. Meguerian stated, "As a U.S. platform registered with the SEC and the Financial Industry Regulatory Authority (FINRA), we operate within a clear regulatory framework while providing founders with access to a global network of Bitcoin investors."

ChainCatcher message, zkSync announced today at 18:00 an upgrade to the behavior of block.number, block.timestamp, and blockhash on zkSync Era. After the upgrade, block.number, block.timestamp, and blockhash will return the L2 block number, timestamp, and hash value, respectively. The upgrade is expected to last 40-60 days, during which the block production rate and timestamp refresh time will gradually increase.zkSync reminds developers that if a project has critical logic dependent on the return values of block.number, block.timestamp, and blockhash, it may face unexpected behavior (e.g., shortened governance voting time, surge in rewards, etc.).

ChainCatcher message, Matter Labs developer relations engineer Antonio stated on Github that important changes are being made to the behavior of block.timestamp, block.number, and blockhash on zkSync Era. Currently, block.timestamp, block.number, and blockhash return the timestamp, number, and hash of the L1 batch, respectively. After this update is completed, they will return the timestamp, number, and hash of the L2 block, respectively.Antonio stated, "Many applications require higher time fidelity, which can be achieved by referencing the L1 batch. With these changes, contracts will be able to time at the L2 block level (approximately generated every few seconds), and this information has already been provided on the API, but with the new changes, developers will be able to access it directly in smart contracts. We are currently developing this change and will internally test the update process before transitioning to the testnet and eventually the mainnet."
