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.
