As more and more L2s launch promising to scale Ethereum, they end up competing for the same market share, userbase and liquidity. Apart from this harsh reality, crosschain interactions should be as seamless as possible in order to bridge different L2 ecosystems. Polygon envisions a scalable future in which various zero knowledge rollups post their proofs on an aggregation layer before settling on Ethereum, thus lowering latency and transaction costs as crosschain interactions take place expeditiously, without involving the L1 mainnet.
