> What most people don’t know is: Gas fees on Ethereum are supposed to be high. The goal for Etheruem is not to be the chain most consumers transact on. It’s to be the settlement layer for a number of other chains sitting on top of it, which can run much faster and much cheaper, because they’re backed by Ethereum’s security and infrastructure. In other words: the consensus layer for a variety of networks.

Is there is source where Vitalik states this? Is this was the case then why bother creating Eth2?

Almost certainly not. Here's a video[1] from at least back in 2017 where he's criticizing bitcoin for having fees of 5 cents per transaction and saying 'The internet of money should not cost 5 cents per transaction, that's absurd.'

Also here's a more recent tweet from him in July 2020 that says the high gas fees are risking making Ethereum even LESS secure[2].

Also here's his response to someone mentioning his initial quote about 5 cents per transaction and accusing Vitalik that he has since become more accepting of higher transaction fees:

"Wait what? Why do you think half the ecosystem is working nonstop on rollups and eth2?"[3]

I think it's safe to assume that Vitalik does not share the opinion of the linked article that Ethereum is intended to have high fees or that it helps security by having those high fees.

Vitalik originally proposed it here: https://ethereum-magicians.org/t/a-rollup-centric-ethereum-r...

ETH2 is where Ethereum goes from Proof of Work to Proof of Stake and as a result uses 99% less electricity.

The second phase of ETH2 is sharding where instead of Ethereum being one big chain it has one execution chain and 64 additional data shards. This makes it scale incredibly well when it's a settlement layer for rollups (up to 14 million TPS with 1024 shards - See https://polynya.medium.com/conjecture-how-far-can-rollups-da...)

Yes and the point there isn't so much that on-chain transactions are "supposed to be expensive," but that zkrollups are just as secure as on-chain transactions but scale an order of magnitude better than executable shards, so executable shards start to look a little superfluous.

The researchers have floated the possibility of incorporating zkrollup tech into L1 eventually, but with the tech advancing so quickly it's hard to say whether it will ultimately make sense.
