Block latency refers to the time it takes for a new block to be added to a blockchain after a previous block. This duration varies depending on the network’s design and conditions. Different blockchain networks have their own target block times.

For instance, Bitcoin aims for a new block approximately every 10 minutes, while Ethereum targets around 15 seconds per block. Factors that influence block latency include network congestion, the speed of node communication, and the block creation process.

Lower block latency can enhance transaction confirmation times, making the network more efficient for users. However, extremely low latency might compromise security, as faster block creation can lead to increased occurrences of forks or chain splits.

Balancing block latency is crucial for ensuring both speed and security in blockchain operations. Ultimately, it plays a significant role in the overall user experience and the functioning of various blockchain applications.
