100 Validators Are Sufficient to Run a Decentralized L1
summary
Claim: 100 validators are economically inevitable because voting costs and fee-sharing push stake to large operators; a 200k SOL node barely breaks even while a 2M SOL node can share ~30 SOL/epoch (~390 SOL/month). That concentrates infrastructure into owners who can afford FPGA, multi‑GPU, dedicated DBs and promise 90% transactions landing same slot and <1s confirmations. Counterclaim: physical security and CAP tradeoffs mean partitions require many geographically and jurisdictionally dispersed nodes, suggesting 500–1,500 validators for real-world economic security.
