Changpeng Zhao, widely known as CZ, said around midday on Sept. 15 that it would be "too cool" if someone built an "immortal fruit fly" on BNB Chain. The remark quickly sparked speculative trading in related BSC-based tokens. According to GMGN market data cited by BlockBeats, on-chain AI agent protocol BORT surged more than 4x in a short period, with its market cap quoted at $3.67 million. NECTAR was quoted at a $1.61 million market cap, while its gain over the past hour reached 367x. The project’s developer said NECTAR uses a Flap buyback-and-burn model driven by real decision-making from a fruit fly brain. The "immortal fruit fly" idea traces back to a recent fruit fly brain model experiment involving about 166,700 neurons. Siyuan, a member affiliated with YZi Labs, wrote earlier in the day that BNB Chain could serve as a permanent layer to store brain states, memories, and interaction history, supporting post-death revival or shared evolution across multiple brains. BlockBeats warned that the tokens involved have small market caps and high volatility, and said investors should stay cautious.
