Maximum performance requires accepting centralized block production
  • Physical latency limits mean decentralization inherently caps performance
  • MegaETH collocates block producers in few data centers for sub-10ms finality
  • Contrasts with Ethereum's ~12s or Solana's ~400ms block times
  • Lei argues this is unavoidable for certain applications (gaming, HFT)

Supporting quotes

If you have a few servers around the world co-producing blocks...it takes some certain amount of time because information travels in fibers at one/third of the speed of light Lei Yang
What layer 2s can serve in this trade-off curve is the far end which is maximizing performance...we want to address a market that is fundamentally impossible for any layer 1 to address Lei Yang

From this concept

The Performance-Centralization Tradeoff

MegaETH's core thesis embraces strategic centralization of block production to achieve unmatched performance, while maintaining Ethereum-level security for finality. This creates a fundamentally different design point from both L1s and traditional rollups.
