Quotes that support claims

He also focused on using Trusted Execution Environments (TEEs) in the short term for RPC privacy. Buterin added that Private Information Retrieval (PIR) could be used in the future.

He suggested starting with Trusted Execution Environments (TEEs) for short-term cryptographic privacy. Afterward, there may be a shift to a Private Information Retrieval (PIR) for stronger protection.
