Nonetheless, a Bitcoin researcher has stepped in to debunk the rumors.

Race at top 941880
As reported by U.As we speak, the community briefly break up into two competing chains at block top 941880.
AntPool mined block 941881, and this was adopted up with block 941882 on that very same path by ViaBTC.
Concurrently, Foundry USA mined its personal variations of blocks 941881 and 941882.

The community briefly had two legitimate chains of equal size till Foundry USA broke the tie by persevering with its streak, mining blocks 941883, 941884 and 941885.

Egocentric mining idea, debunked
Foundry seemingly materialized a number of blocks to overhaul its rivals, and for some, the knee-jerk response was to accuse the pool of “egocentric mining.”
A theoretical assault would contain a miner deliberately withholding legitimate blocks from the general public community to achieve a head begin on discovering the following block, in the end losing the hash energy of competing swimming pools.
In line with the researcher, the information doesn’t assist this malicious narrative. If Foundry was trying a selfish-mining assault, it was executed extraordinarily poorly, provided that the financial incentives have been horrible.
It’s value noting that the occasion came about throughout a low-fee interval. The 2 reorganized blocks solely netted Foundry an infinitesimal 0.025 BTC in transaction charges.
Moreover, on-chain information exhibits that Foundry really spent a second mining on high of the AntPool and ViaBTC blocks earlier than switching again to its personal chain. A miner deliberately withholding a secret chain wouldn’t act this fashion.
The researcher attributes the occasion to plain community latency and using particular Bitcoin Core instructions.
