I'm wondering how many validators can be maxed out in Ethereum 2.0 Proof of Stake algorithm?
1 Answer
The maximum number of validators in Ethereum depends on the total supply of Ethereum.
Each validator needs to stake 32 ether (ETH).
If there's around 100M ether staked, that would be 3M validators.
The total supply of Ethereum will vary because EIP 1559 will burn ETH, and Proof of Stake replacing Proof of Work will reduce the amount of ETH created per block.
Justin Drake, Ethereum Researcher, discusses the supply in Modeling Ultra Sound Money. His spreadsheet from his tweet.

How is it possible to have so many validators? After all, the number of TCP connections is limited. The more connections, the slower the transmission of packets.– chipMay 5, 2021 at 21:02

It sounds like you are assuming that all validators are peered with each other? Found this which some information on how to get the peer count of different validators notes.ethereum.org/@djrtwo/…– eth ♦May 7, 2021 at 1:03
