> The author seems to miss that one of Moxie's central criticisms is that, all else being equal, distributed solutions tend to lag centralized ones.

Distributed crypto offerings do not lag much behind in terms of features, but they are costly and inefficient, which drives most users to centralized solutions.

This creates positive network effects for OpenSea (nft), Binance, Coinbase (crypto trading).

L2 / zk-rollups / validiums have potential to change this balance of power by introducing low-cost, fast transactions.

Which can be achieved by making transaction execution/verification faster through ZK proofs and offloading execution off-chain (without sacrificing security). There is intense competition in the space (zkSync, Polygon Hermez, Starkware, Loopring and others).

Some large players like banks or BaaS companies may create or license their own private rollups.

So far most wallets do not support L2 rollups, I've only heard of Argent supporting zkSync.

This is of course a hybrid solution, not for purists.

Blockchain critics will have fun criticizing it for the next 5 years while it scales. :)
