“This type of node would give the benefits of direct local access to the state that a user needs to care about, as well as maximal full privacy of access to that state,” Buterin wrote.

In the proposal, Buterin’s solution relies on a novel type of node called “partially stateless nodes.” They are designed to help users maintain privacy-preserving access to blockchain data without the heavy resource demands of running a full node.
