ZetaChain 2.0 has introduced an interesting concept—'Privacy Memory Layer.' It encrypts AI conversations and stores them as user-controlled digital assets, enabling seamless transfer across models.

Blockchain here isn’t about hype; it’s genuinely solving the issue of data sovereignty. In the AI era, the scarcest resource might not be computing power, but privacy control.
