Mining Pools Control 51% of Bitcoin
- Two mining pools produced over 51% of Bitcoin since 2020.
- Concerns about centralization and security grow.
- Industry experts urge for decentralized mining solutions.
Two major Bitcoin mining pools have mined over 51% of the total Bitcoin in the last three years. This figure has raised concerns over centralization within the cryptocurrency community.
The event signifies a potential risk to Bitcoin’s decentralized nature, posing security vulnerabilities and control issues.
Analysis of Dual Control Over 51% of Bitcoin Blocks
Recent data shows two leading mining pools accounting for the majority of Bitcoin blocks mined since 2020. Analysts highlight the significant control these entities hold, which could influence transaction validation processes. To understand the impact of such control, consider insights from CryptoSlate.
Pooling resources aids miners in addressing Bitcoin’s mathematical challenges, but excessive consolidation could undermine network security. Crucially, Bitcoin relies on decentralization to deter single points of failure.
Security Risks Intensify with Centralized Mining Power
Security experts caution that centralized mining may heighten risks of 51% attacks, compromising transaction legitimacy. Industry figures express unease, advocating for increased resource diversification among miners to maintain network integrity. According to Chainalysis, unchecked growth of dominant mining pools could lead to network security concerns.
“The concentration of mining power poses a risk to Bitcoin’s decentralization, which is fundamental to its security and integrity.” — Marco Santori, Chief Legal Officer, Kraken

Lessons from Bitcoin’s 51% Attack Threat History
Compared to past scenarios, where no single pool dominated, experts equate the current situation to the 51% attack threats highlighted in Bitcoin’s whitepaper. This pattern leads to discussions about enhancing network resistance through distribution. Insights from a New York University study could inform future policy discussions on Bitcoin governance.
Potentially, if centralization persists, Bitcoin’s trust and operational stability could be challenged. Experts forecast possible regulatory scrutiny aimed at ensuring security, citing previous events such as the GHash.io controversy in 2014. For historical context, the CCN article on Bitcoin’s defense mechanisms explains the significance of exceeding 51% hash power.
