Block Spacing

Block spacing for Qtum averages around 144 seconds, or 600 blocks per day. Block reward difficulty is adjusted to keep this average spacing, but there is some variation in block spacing caused by the random lottery algorithm which selects the block reward winner. The histogram chart below shows the number of block spacings grouped in 16-second buckets for April 15–21, for those block spacings from 2 seconds to 256 seconds. For this period, there were two block spacings greater than 20 minutes, and the longest block was 138,226 at 26:55.
