Bitcoin Hashrate Surpasses 1 Zettahash for First Time

TLDR

• Bitcoin’s hashrate hits 1 ZH/s for the first time.
• Miner revenue per exahash drops to $42.40, a record low.
• Hashrate increased by nearly 7% to 121.5 trillion difficulty.

Bitcoin’s computing power has reached a new high, achieving 1 zettahash per second (ZH/s) for the first time according to Glassnode data dated April 7, 2025. This achievement marks a significant evolution in Bitcoin’s network, illustrating a 1,000-fold increase since 2016 when the hashrate first hit 1 exahash per second (EH/s).

The Bitcoin mining network shows continued growth, currently reporting a hashrate of 860.54 EH/s with mining difficulty at 126.98 trillion at block height 899,358. This comes after a previous reading of 827.38 EH/s with a difficulty of 121.66 trillion at block height 897,674.

Challenges for Bitcoin Miners Amid Growth

Despite these advances, Bitcoin miners face challenging conditions. The hashrate increase occurs even as miner revenue per exahash hits a record low of $42.40. Factors affecting profitability include reduced transaction fees, increased network difficulty, and lower Bitcoin prices, which hover around $77,000 following a 10% decrease influenced by tariffs imposed by President Trump.

The Bitcoin network recently saw a notable difficulty adjustment, increasing by nearly 7% to reach a high of 121.5 trillion. This jump represents the biggest rise since July 2024, with 14 out of the last several adjustments being upward, as per Glassnode data. This adjustment is crucial for maintaining steady block times of approximately 10 minutes.

Insights from Longer-Term Hashrate Trends

Short-term hashrate measurements can be misleading due to natural fluctuations. Analysts recommend using longer-term metrics, such as the 7-day moving average, for more accurate insights. These metrics indicate that, despite market difficulties, the Bitcoin network retains robust growth capabilities.

This milestone in Bitcoin’s hashrate underscores its computational resilience, with the continued expansion of mining power demonstrating the dedication of Bitcoin mining participants. These developments can be explored further in resources like CoinDesk.

Understanding Bitcoin’s Network Data

More detailed network data, including the hashprice index, can be found through specialized sources. Resources such as Hashrate Index provide extensive insights into Bitcoin’s hashprice and hashpower trends.

Comparative information about Bitcoin hashrates over time is available on platforms like BitInfoCharts, offering analysis of network growth over periods. These tools are essential for understanding the broader impact of changes in Bitcoin’s computational power.
