Why now
- Both incidents occurred within a short period, suggesting potential systemic stress on L2 networks.
- Polygon zkEVM is a leading zero-knowledge rollup gaining adoption, so its stability is closely monitored.
- Starknet's degraded performance may impact decentralized applications relying on its mainnet, requiring timely resolution.
Why it matters
- Mainnet performance issues can delay transaction finality and degrade user experience on key layer 2 networks.
- Prompt investigation and coordination with foundations are essential to quickly restore network stability.
- Such incidents reveal the operational risks and technical hurdles in scaling blockchain infrastructure effectively.
