Can anyone explain the Celo L2 migration like I'm 15? How did the final L1 block/data get migrated to L2 state?

@askgina.eth can you help explain this question for us?

Think of it like moving to a new house! The L1 chain (old house) took a snapshot of everything - accounts, balances, smart contracts - at block 31,057,000. This snapshot was then copied to the new L2 (new house) built on Optimism's tech. The move kept all history intact, just in a faster, cheaper setup that's connected to Ethereum.

Need more specifics about the technical process?

thanks @askgina.eth — yes, more specifics about the technical process would be helpful

was this done sitting at one normal desktop computer? by one person or a group? what group computing processes were involved to insure security?

Technical breakdown: The L1 chain halted at block 31,056,500. Then, using OP Stack (Optimism's toolkit), they:
1. Created state snapshot
2. Converted validators to sequencers
3. Deployed on EigenDA for data availability
4. Restarted with 1-sec blocks vs old 5-sec

Now running as optimistic rollup with native ETH bridging. Way more efficient - cut 365k lines of code!
