Approximately 60% of bitcoin blocks are merge mining other chains (since the last halving).

That's down from a peak of 96% in April 2020.

For our latest mempoolresearch (npub1m7q…m4gz) report, OrangeSurf (npub18h0…ws8m) analysed which merge mining schemes are in use, and which miners are using them.

Looking at recent data we see different miner / pool groups.

Group 1. No Merge Mining
Foundry, MARA, SBI Crypto

Group 2. AuxPow & “Chain A”
ViaBTC, F2Pool & Luxor

Group 3. Distinct switching pattern
Binance Pool, BTCcom, Poolin, Braiins, ULTIMUS

Group 4. Other
Antpool, SECPOOL

Taking a longer view looking back to the genesis block we see that adoption of schemes has fluctuated wildly over time!
