Key Resilience Drivers Proof-of-History consensus and global validators ensured stability. Solana’s stablecoin market cap hit $15 billion post-outage, per DeFiLlama. This reflects growing institutional confidence. Centralization Risks Exposed The outage highlighted crypto’s reliance on centralized infrastructure. Layer-1s like Solana, Bitcoin, and Ethereum outperformed Layer-2s. Experts urge broader backend diversification. Solana’s resilience rebuts earlier outage critiques.
