Decentralization and Security
Ethereum's Proof-of-Work system currently boasts:
- 6,373 nodes maintaining network security
- 60% hash rate controlled by top 3 mining pools
- Planned upgrade to 306,169 validators post-Merge
Solana's Proof-of-Stake model shows:
- 1,576 validators securing the network
- 75%+ staked SOL from circulating supply
- 48% initial SOL distribution to internal parties
Security Winner: Ethereum's broader node distribution and upcoming validator expansion make it the more decentralized choice despite mining pool concentration.
