It’s a fair point, but it’s unclear to me to what extent these hybrid solutions retain the advantages of blockchain and to what extent they give them up. I’m not at all an expert, but I’ve been wondering if a world where we all regularly use Bitcoin, but only via large, centralized L2 networks, would be one which feels exactly like the world of today, except (say) Visa or Stripe use Bitcoin instead of…fedwire? I dunno?…for clearance. And as a user, would that actually benefit me?

> what extent these hybrid solutions retain the advantages of blockchain and to what extent they give them up Security guarantees don't change, zk-proof will guarantee that your transaction was processed as is (without modifications). The resiliency of a rollup would depend on how it's off-chain "backend" is implemented - if it has good load-balancing, if it is multi-cloud etc. It's possible that a specific rollup can try to censor your transaction (similar to Visa or Mastercard). I can see a future where if a specific rollup cannot accept your transaction, your wallet would retry successfully with another rollup or try a censorship-resistant channel to push your transaction through. Transaction fees being negligible simplify the UX for user, they may not even know there was any problem unless they look. This is a good post (somewhat technical) on rollups in Ethereum ecosystem and the areas for improvements: https://vitalik.ca/general/2021/12/06/endgame.html https://vitalik.ca/general/2021/12/06/endgame.html I don't know much about Bitcoin L2 networks, but it makes sense that lots of infra/business logic around that would be implemented by centralized companies (Square, Stripe?). No smart contracts support is a limiting factor.
