The provided text analyzes the competitive landscape of Ethereum Layer 2 scaling as of late 2025, specifically comparing the technical architectures of zkSync Era and Polygon zkEVM. Both systems utilize zero-knowledge proofs to boost transaction speeds and lower costs, yet they employ different strategies for achieving scalability and security. zkSync Era focuses on a modular Elastic Network of interconnected chains using its RISC-V based Airbender prover to reach massive throughput. Conversely, Polygon emphasizes absolute EVM equivalence and liquidity unification through its Aggregation Layer and Type 1 prover. The overview highlights how innovations like Proto-Danksharding have revolutionized the economics of these networks, making decentralized finance more accessible. Ultimately, the sources suggest that these evolving technologies are transforming Ethereum into a robust, multi-chain settlement layer for global digital value.
