The Solana runtime and Anchor framework simplify state management, allowing developers to maintain speed and efficiency without sacrificing user experience [11].

Transaction Speed & Cost

When comparing "speed" in blockchains, it’s important to understand the difference between two key metrics: Throughput (TPS) and Time to Finality. Each measures something different, and which one matters more depends on your specific use case.

Throughput (TPS): The maximum number of transactions the network can process per second. This is a peak capacity indicator.

Time to Finality: The time it takes for a transaction to be considered irreversible. This is the key metric for users who need certainty (e.g., traders, merchants).

WHAT IT MEANS:

• Theoretical TPS = Network potential, not daily reality
• Real-World TPS = Actual throughput under normal load
• Time to Finality = Key differentiator - Sei provides near-instant irreversibility
• Transaction Cost = Both offer negligible fees
