> ETH's L2 ecosystem

How does this work? It feels like moving all of this off the blockchain loses a bunch of the supposed value.

If I move to a “side chain” do I get to keep the guarantees around settlement? I would assume no, not until this gets worn back to the block chain.

I think I understand (theoretically) how the side chain would increase throughput and reduce transaction fees, but these benefits as I understand them come specifically from making the side chain high volume. If I need to do one transaction with you, the side chain is redundant, right?

Good to know. I only know what I learned in maybe 20 minutes of research.



L2 doesn't have to mean you leave the chain, it means you 'batch' transactions using this technique, generally : https://ethereum.org/developers/docs/scaling/optimistic-roll...

Not all L2 are about throughput exclusively, some are, for example, more focused on private ZKSnark based transactions. There is a huge quantity of development out there.

Generally the security guarantees on L2 range from identical to the main chain to 'good enough' to 'I pinkie promise not to take your money'. It's a permissionless protocol so that's kinda what you get.


Thanks for the link. I’ll have to read up.
