Disclaimer: I work on Ethereum core development. One of the coolest things happening that will be available to everyone over the coming year is something called a light client, which is essentially a very light, validating node that tracks the head of the chain with certainty, and can be used as an alternative to services such as Unfura. In the future, Metamask will probably be a light client that actually tracks the head of the chain and can validate proofs of user account state.

The total ETH created does depend on the amount staked. Here's a table[1] and formula[2]. The total reward doesn't go up linearly with the number of validators, but it does go up. Lowering the incentive for attacks like you mention is a reason for that. And while having fewer validators gives you a somewhat higher reward per validator, it's still that case that all validators get the same reward in any given block. Everyone is equally competitive. Someone who reinvests will get higher absolute rewards than they got before, but they pay the price of locking up more capital. In the same way, a miner could reinvest profits into more mining equipment, but that doesn't make them more competitive, just bigger. Their profit margin will be the same (barring economies of scale that don't exist in staking). [1] https://docs.ethhub.io/ethereum-roadm

As of 01 Dec 2020, there is already another Ethereum mainnet chain (Eth2 Phase 0) running in parallel with and dependent upon the Eth1 mainnet chain: https://beaconcha.in/ https://beaconscan.com/ https://github.com/ethereum/eth2.0-specs/tree/dev/specs/phas... Vitalik is proposing a role reversal to take place earlier than it was previously planned (not completely accurate in a technical sense re: previous plans, but effectively the same): Eth1 mainnet will hand-off consensus responsibility to Eth2 mainnet (PoW -> PoS), while Eth1 nodes continue to "run the code" that executes smart contracts / processes transactions. If the plan is put into motion, and as long as some miners / mining pools don't yank the plug on their mining nodes in the canonical Eth1 mainnet, then the canonical mainnet — per consensus among the Ethereum Foundation and a

It involves something called the staking deposit contract: https://ethereum.org/en/eth2/staking/ https://launchpad.ethereum.org/overview/ Picking any active validator on the Beacon Chain, we can see that there is an Eth1 deposit and a corresponding Eth2 deposit: https://beaconcha.in/validator/91676#deposits https://beaconscan.com/validator/91676#deposits If you're interested in the technical details, see: https://github.com/ethereum/eth2.0-specs/tree/dev/specs/phas...
