Coin World reports:
The competition in Bitcoin mining always produces leaders. After the most recent halving, the network is now dominated by only two mining pools, which generate over 60% of the blocks.
Bitcoin mining is entering a new mature stage, where mining pools are vying for the reduced block rewards. Typically, around 50% of the blocks flow to four leading pools. However, the shift in investments has changed the landscape of the mining industry, making the two major pools the top block producers.
The two major pools with the highest output are Foundry USA and Antpool. Together, they possess over 51% of the hash power, theoretically capable of attacking the Bitcoin network. So far, there hasn’t been collusion among producers in Bitcoin, but it would take at least three pools to control 51% of all mining.
Within a seven-day timeframe, these two pools also produced 55% of all the blocks, with over 29% flowing to Foundry. Pools do not necessarily control all the miners; only a portion of the hash rate is under their direct control. Theoretically, miners can choose to switch pools, but most miners still remain with the larger producers to have a higher chance of receiving a share of the rewards.
Update: Two entities now control 63% of the Bitcoin block production in pool 3#, with their known proxies controlling 76%. https://t.co/NfhhackfjSpic.twitter.com/uKIugGse5i – Evan Van Ness
