introduction In the world of blockchain, Meme coins are not only a speculative tool, but also the core driving force of the attention economy. In recent years, the narrative of Meme coins has continued to expand, no longer limited to simple Internet culture, but has penetrated into high-value fields such as scientific research and space exploration, giving the market more room for imagination. From DeSci (decentralized science) to Banana for Scale, these narratives not only expand the application boundaries of blockchain, but also provide investors with a new path for value discovery. This article will explore the logic of the rise of DeSci and Banana, as well as the potential and risks of other emerging Meme hotspots.
