Polygon zkEVM development has become popular over other layer 2 solutions due to its advantages. While networks like Arbitrum and Optimism use optimistic rollups,  Polygon zkEVM uses zero-knowledge proofs that verify transactions instantly at lower cost. 

Many zk-rollups require code modifications, but Polygon zkEVM aims for bytecode-level equivalence, meaning that Solidity contracts work without modification, Ethereum tools/frameworks work natively, and require the same gas cost structure & same opcodes.

Polygon zkEVM uses recursive proofs, efficient polynomial commitments, and parallelized proof generation, making proof submission cheaper for users compared to earlier zk-rollups. Also, it offers higher TPS, keeps costs low even during network congestion, and scales better.
