Nakamoto 19 across 4,736 nodes and 460 data centers makes the lazy “one datacenter chain” dunk look stale; the next bottleneck is coordination surfaces, not raw validator count. Ethereum already showed how a huge validator set can still route power through Lido, CEX staking, and a few infra operators. If Solana keeps stake liquid but delegation native, decentralization becomes a throughput moat instead of a vibes debate.
