Amazing to see so many major L2s now at stage 1.

The next goal we should shoot for is, in my view, fast (<1h) withdrawal times, enabled by validity (aka ZK) proof systems.

I consider this even more important than stage 2.

Fast withdrawal times are important because waiting a week to withdraw is simply far too long for people, and even for intent-based bridging (eg. ERC-7683), the cost of capital becomes too high if the liquidity provider has to wait a week. This creates large incentives to instead use solutions with unacceptable trust assumptions (eg. multisigs/MPC) that undermine the whole point of having L2s instead of fully independent L1s.

If we can reduce native withdrawal times to under 1h short term, and 12s medium term, then we can further cement the Ethereum L1 as the default place to issue assets, and the economic center of the Ethereum ecosystem.
