When Satoshi Nakamoto conceived Bitcoin (BTC), the security of this revolutionary digital currency was predicated on a consensus mechanism known as Proof-Of-Work (PoW). However, the current state of consensus decentralization might be placing Bitcoin’s security on shaky ground. This is a concern that has been raised by crypto researcher Chris Blec, who recently pointed out that two mining pools, both requiring miners to complete Know Your Customer (KYC) procedures, control 55% of the Bitcoin hash rate. This situation could potentially spell trouble for Bitcoin, yet it seems to be largely ignored by the community.
Bitcoin Mining Pool Centralization: A Cause for Concern?
The chart that Blec referred to shows Foundry USA and AntPool each accounting for 27.6% of Bitcoin’s global hashrate. These two Bitcoin mining pools are essentially cooperatives of Bitcoin mining companies aiming to enhance block discovery and, consequently, their profits. But what does this dominance of two pools mean for Bitcoin’s consensus?
Blec’s concern is not just about the dominance of these two pools, but also about the apparent lack of awareness within the community about this issue. The centralization of Bitcoin mining has been a growing concern over the years, and it’s a topic that deserves more attention.
Why Does Bitcoin Mining Pool Centralization Matter?
As it stands, Bitcoin mining pools operate in a centralized manner under the coordination of the pool’s coordinator. This coordinator is responsible for creating the block template, filtering out unwanted transactions, discovering the next block using their miner’s hashrate, broadcasting the mined block to the network, collecting the mining reward, and distributing it proportionally to the miners. This single entity carries out actions that directly affect Bitcoin’s security.
Recently, there have been instances of mining pools arbitrarily deciding not to pay their miners on certain occasions. Specifically, F2Pool and AntPool, which hold 8.8% and 27.6% of the global block discovery rate, respectively, have been implicated in such practices. There was also a case where a newly established Bitcoin mining pool was accused of intentionally filtering privacy-related BTC transactions. These events underscore the importance of having a decentralized pool-based consensus.
Implications for Bitcoin’s Value Proposition
Bitcoin’s value proposition is intrinsically linked to its security and decentralization. The current state of the network could potentially impact the market’s perception of the leading cryptocurrency’s value.

While the issue of Bitcoin mining pool centralization may not be at the forefront of every investor’s mind, it is a factor that could potentially impact the long-term stability and value of Bitcoin. Therefore, it is an issue that deserves our attention and discussion.
