Introducing the Merge Mining Monitor, another tool in service of the Bitcoin monitoring mission.
Merge mining lets child chains ride on Bitcoin's PoW, preserving the parent headers miners hashed.
Bitcoin keeps no durable record of valid blocks it later discards (stales/orphans). Merge-mined chains do.
The monitor turns that merge-mining evidence into a browsable record of who mined each Bitcoin block, which child chains rode along, and which discarded blocks survived in child-chain history.
The current dataset recovers 2,200+ stale blocks back to 2011, when Namecoin first brought merge mining to Bitcoin.
