Vitalik Buterin emphasizes the importance of encryption privacy for local AI agents, which can prevent the leakage of user behavior during API calls. He mentioned that hybrid networks can initially hide behavior, but service providers need to implement anti-DoS mechanisms, and payment processes involve tracking risks. Encryption technology can effectively protect user privacy.

Odaily News Regarding the community's discussion on "Ethereum still setting a contract size limit", Vitalik Buterin responded that it is due to DoS risk considerations. He stated that once Ethereum's state structure is upgraded to a unified binary tree (EIP-7864), it is expected to achieve unlimited contract size, but the Gas fees and mechanism design for publishing super large contracts still need to be addressed. Currently, based on the cost of creation per byte, the actual contract limit is approximately 82KB.
