You’re absolutely right to be concerned, when two mining pools collectively control more than 51% of Bitcoin's total hashrate, it's a potential centralization red flag that warrants attention. That doesn’t necessarily mean an imminent breach, but it does raise risks. Let’s break it down clearly: 👇👇👇
What’s Actually Going On
Recent reports indicate that Foundry USA and AntPool jointly control around 57% of Bitcoin’s total mining hashrate. These figures and the evolving dynamics have sparked growing concerns about mining centralization.
Why Does This Matter?
1. The Risk of a 51% Attack
With more than half of the network's computing power, these pools could, in theory:
✓Reorder or censor transactions.
✓Double-spend coins.
✓Manipulate block confirmations to their advantage.
In June 2014, GHash.io briefly crossed the 51% threshold, causing panic and a temporary price dip from ~$633 to ~$600. On the Bitcoin Cash network, BTC.com and BTC.top successfully executed a 51% attack in 2019. Other chains like Ethereum Classic and Bitcoin Gold have also suffered such attacks, leading to double-spends.
2. Centralization Undermines Decentralization:
Bitcoin was built to be decentralized, but mining centralization undermines that principle. A few large entities controlling a significant portion of the network raises the risk of collusion and regulatory or geopolitical influence.
3. Economic and Governance Implications:
If mining power centralizes, these pools could resist or override network upgrades by not adopting new protocol rules. Their actions would overshadow community decisions simply because they control consensus.
Is This an Immediate Threat?
It's more of a latent threat with high potential rather than an active crisis. Currently, there's no public evidence that Foundry or AntPool are abusing their control or staging an attack. However, the concentration still poses risks, should they ever choose to act maliciously or politically.
What Can Be Done?
Structural and community responses:
✓Voluntary caps: In the past, GHash.io voluntarily limited its hashrate to below 40% to ease fears.
✓Decentralized mining tools: Solutions like the OCEAN pool aim to redistribute control by empowering miners to choose their own block templates, injecting more autonomy back into the system.
✓Monitoring & transparency: Keeping public scrutiny on pool shares (via Blockchain.com, MiningPoolStats) helps push pools to stay accountable.
In summary, Is It a Threat?
Yes—potentially.
While this isn’t a smoking gun, the fact that two pools command over half of Bitcoin’s hashrate poses a structural risk. It doesn’t guarantee an attack, but it does elevate the stakes. The market, regulators, and the community should remain vigilant to ensure the network stays decentralized and resilient.
