Ethereum is now the main capital hub of ZKsync

ZKsync's Atlas upgrade is presented as letting ZK chains use Ethereum itself as a real-time liquidity hub instead of building separate central liquidity pools. The text cites 15k+ TPS, one-second ZK finality and near-zero fees, but says these are a small part of the story. It claims Atlas brings L2-to-L2 interop to around one second and L1-to-L2 interop latency below the finality time of an Ethereum block, removing the need for a separate hub for institutional and RWA flows. It contrasts this with optimistic rollups, where L1-L2 interaction can take up to seven days to finalize.
