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 @mempool research report, @OrangeSurf 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!
