Opside is a 3-layer scaling platform providing ZK-Rollups as a Service, whose layer 2 is an EVM-compatible and Rollup-friendly chain, and layer 3 is a collection of different zkRollups. Layer 2, or Opside chain, has made many system-level optimizations for zkRollup and introduced the concept of the native rollup.
Layer 2 and 3 of the Opside architecture share a consensus mechanism that integrates PoS and PoW.
