✅ Master Block Time Trade-offs

Understand why blockchains choose different block times and finality models

Key Takeaways

Let's review the critical concepts about block time and test your understanding.

⏱️

Block Time Fundamentals

Block time is the average interval between blocks. It fundamentally shapes security, user experience, and network architecture. Different blockchains optimize for different priorities.

⚖️

The Speed-Security Trade-off

Faster blocks improve UX but increase orphan rates and centralization pressure. Slower blocks maximize security and decentralization but hurt usability. Every choice involves trade-offs.

🌐

Network Effects Matter

Network latency, orphan blocks, and propagation delays all interact with block time. Global, decentralized networks face physical constraints from the speed of light.

🎯

No Universal "Best"

Bitcoin's 10 minutes, Ethereum's 12 seconds, and Solana's 400ms all serve different purposes. The "right" block time depends entirely on your priorities and use case.
