Description
- Centralization of Validators
Core Issue: Solana sacrifices decentralization for high TPS, concentrating validator control among capital-heavy entities due to extreme hardware requirements (high-end CPUs, massive RAM, enterprise-grade bandwidth).
Critical Evidence:
Nakamoto Coefficient historically dipped below 30 (only <30 entities needed to compromise the network)
Node operation excludes ordinary users
Aggregator Impact: "Censorship-resistant" claims become hollow—top validators could collude to manipulate transaction order.
- Unreliable Network Uptime
Core Issue: Repeated catastrophic outages (2021-2023) expose critical instability.
Critical Evidence:
Multi-hour global halts caused by bot floods/code bugs
Frequent performance degradation during peak loads
Aggregator Impact: Network failure during market volatility traps users, causing irreversible financial loss.
- Monoculture in Core Infrastructure
Core Issue: Heavy reliance on Solana Labs’ single client (Firedancer remains immature), unlike Ethereum’s battle-tested multi-client approach.
Critical Evidence:
Contrast with Ethereum’s robust client diversity (Geth, Nethermind, Besu, Erigon)
Single-point-of-failure risk remains high
Aggregator Impact: A core client bug could cascade into ecosystem-wide blackout.
This positions Ethereum as the mature solution while objectively highlighting Solana’s operational risks for serious builders.
