Bitcoin hashrate approaches the zettahash mark, setting a new peak of 943 EH/s

When the price of Bitcoin is in the accumulation phase after the historical peak (ATH), the computational power of the network has reached an unprecedented milestone: hitting a peak of 943 exahash per second (EH/s).

According to the simple moving average data (SMA) for 7 days, the global hashrate of Bitcoin reached a new high of 943 EH/s on May 31, just 22 days after the previous record of 929 EH/s. This increase of 14 EH/s indicates a strong momentum in the processing capacity of the network.

Notably, the figure of 943 EH/s is only 57 EH/s away from the milestone of 1 zettahash per second (ZH/s)—making a significant step closer to the historical threshold. Although the hashrate slightly decreased on June 1st, it remains at an impressive level: approximately 934 quintillion hashes per second performed on the Bitcoin blockchain at 6:02 PM Vietnam time on that Sunday.

The most powerful distributed computing system on the planet?

Although many people have likened the Bitcoin network to the most powerful computing system in the world, a direct comparison with supercomputers is not entirely appropriate. Bitcoin's hashrate is based on integer operations, while supercomputers are measured in FLOPS (floating-point operations per second), which serve completely different types of tasks.

However, preliminary estimates once suggested that the hashrate of Bitcoin could perform more calculations than top supercomputers like El Capitan— which has a power of 1.742 exaflops. But once again, comparing two types of systems with fundamentally different natures is like placing poetry next to mathematics—one cannot use the same measure.

Notably, the computing power of Bitcoin is distributed globally, operating non-stop—24/7. Although interruptions or temporary device shutdowns may occur, this has not happened in 2025; rather, miners continue to enhance their hash power contributions to the network.

Profits are down, but hashrate is still increasing

Notably, the recent increase in hashrate has occurred against the backdrop of a 7.93% decline in revenue per petahash since May 29. At that time, the expected revenue for 1 PH/s was 56.99 USD; currently, this figure has decreased to 52.47 USD.

Although profit margins are becoming thinner and the market has not fully recovered from the fourth halving event last April, the continuous increase in hashrate reflects the confidence of miners and the rising technological ambitions. The network is becoming increasingly efficient, despite volatility in profits.

What is Zettahash?

Zettahash (ZH/s) is a unit of measure for hash rate (hashrate) that is extremely large, used to measure the computational power of blockchain networks like Bitcoin.

1 zettahash is how much?

1 zettahash/second (ZH/s) =

= 1,000,000,000,000,000,000,000 hashes/second

= 10²¹ hashes per second

= 1 million exahash/second (EH/s)

Comparison of units:

| Unit | Abbreviation | Hashes per second | | --- | --- | --- | | Kilohash | KH/s | 10³ = 1.000 | | Megahash | MH/s | 10⁶ = 1 million | | Gigahash | GH/s | 10⁹ = 1 billion | | Terahash | TH/s | 10¹² = 1.000 billion | | Petahash | PH/s | 10¹⁵ | | Exahash | EH/s | 10¹⁸ | | Zettahash | ZH/s | 10²¹ (1.000.000 EH/s) |

The fact that the Bitcoin network is approaching 1 ZH/s means that the entire system is performing about 1,000,000,000,000,000,000,000 hashes per second — a colossal number, demonstrating the collective computing power that global miners are putting into the network. This is a historic milestone, indicating that the Bitcoin network is becoming increasingly secure and decentralized.
