A researcher at the Ethereum Foundation (EF) revealed that the IP addresses of Ether stakers are monitored as part of a broader set of metadata, causing the cryptocurrency community to flag Ethereum for privacy concerns.

In an April 12 interview on the crypto podcast Bankless, EF researcher Justin Drake revealed that he learned this information “internally” — presumably at EF.

The metadata Drake referred to is used to track a wide range of things, he explained:

“There’s a lot of metadata, you can look at deposit addresses, you can look at withdrawal addresses, you can look at fee recipients, you can look at IP addresses.”
