最新报道：According to Bijie.com, data shows that two major mining pools currently control over 51% of Bitcoin's total computing power. Bitcoin has long been considered a symbol of decentralization and financial independence. However, recent developments have revealed the drawbacks of centralization within the Proof-of-Work (PoW) mechanism. Could Bitcoin face a 51% attack? According to analyst Jacob King, Foundry currently holds a 33.63% market share of Bitcoin mining hashrate, while AntPool holds 17.94%. Together, these two mining pools control over 50% of the network's hashrate, raising concerns about centralization in Bitcoin mining. This means that if the two Bitcoin mining pools merge, they would exceed the 51% hashrate control threshold. This theoretically opens the door to attacks aimed at manipulating the network. Some community members have also publicly acknowledged that Bitcoin mining has become "extremely centralized." Statistics from Evan Van Ness show that three mining pools regularly hold over 80% of the global hashrate. This marks the first time in over a decade that mining concentration has reached such a dangerous threshold. This has shaken the community's confidence in decentralization, the foundation of Bitcoin. Many experts question whether the Proof-of-Work (PoW) mechanism remains suitable as a pillar of the global financial system. Its vulnerabilities, such as the risk of a 51% attack, have raised concerns about its long-term viability. Some analysts warn that this scenario could transform Bitcoin from a decentralized asset into one perceived as "risky and burdensome" by institutional investors. This shift could also impact the broader financial system. In the event of a 51% attack, controlling mining pools could manipulate transaction verification and block or reverse confirmed transactions. This could also lead to double spending, compromising the integrity of the Bitcoin network. Such a scenario would result in economic losses and undermine confidence in Bitcoin as a safe haven asset. Despite the hash rate and difficulty currently reaching all-time highs, concerns about a potential 51% attack have added psychological pressure to the market. Experts point out that executing a 51% attack on Bitcoin is extremely costly, requiring significant infrastructure and energy resources. This high barrier to entry makes such an attack logistically challenging despite the concentration of mining power. Furthermore, mining pool economic incentives may limit the likelihood of a 51% attack, as it could cause a price crash in Bitcoin. Such a crash would directly harm those who control the hash rate. However, the perception that Bitcoin is vulnerable to a 51% attack could generate significant concern among investors. This fear alone is sufficient to raise concerns about systemic risk.
