1. It needs 2 million deposited Ether to start
We covered previously how a validator would need to submit 32 ether to a deposit contract to join the staking system in Ethereum 2. What isn’t as widely known is that we need 65536 validators for the new chain to start – roughly 2 million ether (65536 validators). That’s exactly 64 validators per planned shard in the system – too little at first (see numbers below).
