According to BlockBeats, on July 4, the Central Bank of Brazil stated at a congressional hearing that stablecoins have the attributes of payment instruments and should be classified as electronic money instruments rather than general digital assets, and therefore should be included in a stricter regulatory framework.

The Brazilian Crypto Economy Association opposes this classification, arguing that it could trigger regulatory conflicts, inhibit the application of stablecoins in institutional and retail markets, and deviate Brazil from international regulatory trends. Meanwhile, the Central Bank of Brazil has recently increased regulatory requirements for virtual asset service providers, potentially putting pressure on small and medium-sized crypto institutions.

According to BlockBeats, on July 4th, Serenity stated that floating AI data centers and ocean computing already exist, with their core advantages lying in significantly reducing electricity consumption through natural seawater cooling and being particularly beneficial for areas with limited land resources, similar to the concept of "orbital computing." Samsung Heavy Industries plans to launch its first commercial floating AI data center, with a scale of approximately 50MW, in 2028, while Singapore's Keppel is also advancing a similar project, expected to be operational in the same year.

Serenity also stated that Microsoft previously explored underwater submerged data centers under the name Project Natick, but this project has been terminated. This is not the same concept as the floating data centers currently being discussed. This addresses two major pain points in AI infrastructure: power and cooling. Furthermore, its modular and mobile characteristics are naturally well-suited for areas with scarce land.

According to BlockBeats, on July 4th, Micron Technology officially launched the expansion project of its western Japan factory, with a total investment of 1.5 trillion yen, for the production of advanced memory chips. This expansion is part of its global capacity expansion plan, aiming to meet the needs of the artificial intelligence industry; the Japanese government will provide subsidies of up to 500 billion yen to share the construction costs. This factory expansion will help Micron improve the energy efficiency and data transmission efficiency of chips required for artificial intelligence services and autonomous vehicles. The expanded production line is expected to be operational and shipping around the summer of 2028.
