Another proposal is to reduce the time between each block generation.
The time between blocks can be decreased to achieve faster finalization of blocks but may result in less security due to the increased number of forks.
A Complete Guide to Understanding This Blockchain Concept
Ethereum has achieved a block time of approximately 14 seconds.
This is a significant improvement from the Bitcoin blockchain, which takes 10 minutes to generate a new block.
In Ethereum, the issue of high orphaned blocks resulting from smaller times between blocks is mitigated by using the Greedy Heaviest Observed Subtree (GHOST) protocol whereby orphaned blocks (uncles) are also included in determining the valid chain.
Once Ethereum moves to Proof of Stake (PoS), this will become irrelevant as no mining will be required and almost immediate finality of transactions can be achieved.
Why This Matters for Blockchain Technology
Understanding Block interval reduction is not just an academic exercise — it has real-world implications for how blockchain systems are designed, deployed, and secured. Whether you are a developer building decentralized applications, a business leader evaluating blockchain adoption, or a curious learner exploring the technology, this knowledge provides a critical foundation.
