The Scaling Arms Race Has a Hidden Variable: Centralization

Solana's Firedancer (1M TPS) and Ethereum's Glamsterdam headline crypto's performance narrative. But both chains are racing to resolve a symmetric centralization problem — 70%+ single-client stake on Solana, 24.2% Lido dominance on Ethereum — before an adversarial event exposes the flaw.
