Distributed systems disagree not only about state, but about sequence.
Why it matters
Performance is meaningful only beside hardware demands, decentralization, application demand and operational resilience.
The design claim
Proof of History creates a cryptographic sequence that participants can verify, reducing some coordination overhead around time and order. It is one component, not Solana's complete consensus system.
What speed made possible
High capacity supports exchanges, payments, consumer applications and rapid state changes. It also raises the standard for reliable infrastructure and validator accessibility.
Disputed and evolving
Critics focus on hardware intensity, validator concentration and the history of network disruptions; supporters point to improving clients, demand and throughput. Both belong in the record.
