The Bitcoin Cash (BCH) network hashrate is a critical metric that reflects the overall computational power securing the blockchain. As one of the most prominent proof-of-work cryptocurrencies, BCH relies on miners to validate transactions and maintain network integrity. Understanding hashrate—what it means, how it’s measured, and why it matters—offers valuable insight into the health, security, and future potential of the Bitcoin Cash ecosystem.
What Is Hashrate? A Beginner’s Guide
Hashrate is a measure of computational performance in cryptocurrency mining. Specifically, it refers to the number of hash calculations a mining device can perform per second. In the context of Bitcoin Cash, each "hash" represents an attempt to solve a complex cryptographic puzzle required to mine a new block.
The higher the hashrate, the more guesses a miner can make per second, increasing their chances of successfully mining a block and earning rewards. Hashrate is typically expressed using standard units:
- 1 Kh/s = 1,000 hashes per second
- 1 Mh/s = 1,000 Kh/s = 1 million h/s
- 1 Gh/s = 1,000 Mh/s = 1 billion h/s
- 1 Th/s = 1,000 Gh/s = 1 trillion h/s
- 1 Ph/s = 1,000 Th/s = 1 quadrillion h/s
- 1 Eh/s = 1,000 Ph/s = 1 quintillion h/s
These units help quantify everything from individual GPU performance to the total power of an entire mining network.

How Does Mining Work? The Role of Hash Functions
Mining on the Bitcoin Cash network involves repeatedly applying a cryptographic hash function—specifically SHA-256—to find a value that meets the network's current difficulty target. Each attempt generates a “solution,” or hash. This process is often described as a guessing game because miners are essentially trying billions or trillions of values per second until they find one that satisfies the required conditions.
For example, a single NVIDIA GTX 1070 Ti GPU can achieve approximately 340 Mh/s, meaning it performs 340 million hash operations every second. While this may seem high, modern ASIC miners operate at speeds exceeding 100 Th/s, making GPU mining largely obsolete for BCH.
Once a valid solution is found, the miner broadcasts the new block to the network for verification. The blockchain then updates, and the process begins anew with a fresh set of data and a new target.
This continuous cycle ensures decentralization and security. The more computational power (i.e., hashrate) dedicated to the network, the harder it becomes for any malicious actor to alter past transactions—a concept known as network security through hash power.
What Is Network Hashrate and Why It Matters
The Bitcoin Cash network hashrate represents the combined mining power of all active miners across the globe. As of now, the BCH network operates at approximately 3.48 EH/s (exahashes per second)—equivalent to over 3.48 quintillion calculations per second.
This staggering number isn’t arbitrary. It’s directly tied to two key factors:
- Network Difficulty: Adjusted roughly every 2016 blocks (about two weeks), difficulty ensures that new blocks are mined approximately every 10 minutes, regardless of changes in total hashrate.
- Block Time Consistency: Even if more miners join or leave the network, the protocol automatically recalibrates difficulty to maintain stable block intervals.
A rising network hashrate generally signals growing interest and confidence in Bitcoin Cash. It suggests more miners are investing in hardware and electricity to support the network, which enhances resistance to attacks like 51% takeovers.
Conversely, a declining hashrate could indicate reduced miner incentives—often due to falling coin prices or rising operational costs—which may raise concerns about long-term network resilience.

How Is Network Hashrate Calculated?
The Bitcoin Cash network calculates its global hashrate based on three primary inputs:
- Current network difficulty
- Targeted block time (600 seconds for BCH)
- Actual time between recent blocks
By analyzing how quickly recent blocks were discovered compared to the expected interval, the system estimates the total computational effort being applied across the network.
For instance:
- If blocks are found faster than every 10 minutes on average, the estimated hashrate increases.
- If blocks take longer, the estimate decreases.
This calculated value is then displayed on blockchain explorers and mining dashboards as the current network hashrate—providing transparency and enabling miners to assess profitability.
Frequently Asked Questions (FAQ)
Q: Can I mine Bitcoin Cash with my home computer?
A: Technically yes, but it’s no longer practical. Modern BCH mining requires specialized ASIC hardware due to intense competition and high network difficulty. Consumer GPUs or CPUs would take years to mine a single block and likely consume more in electricity than they earn.
Q: Does higher hashrate mean higher transaction speed?
A: Not directly. Bitcoin Cash targets a block time of 10 minutes regardless of hashrate. However, higher hashrate improves network security and stability, reducing the risk of chain splits or double-spending attacks.
Q: Where can I check the live Bitcoin Cash hashrate?
A: You can view real-time metrics on blockchain analytics platforms or mining pool dashboards. These tools display current difficulty, hashrate trends, block times, and more.
Q: How does halving affect network hashrate?
A: Block reward halvings reduce miner income by 50%, which can lead to temporary drops in hashrate as less efficient miners shut down. However, if price rises post-halving, profitability may recover, attracting miners back.
Q: Is low hashrate dangerous for Bitcoin Cash?
A: A significantly low or rapidly declining hashrate can make the network vulnerable to 51% attacks, where a single entity gains majority control over mining power. Fortunately, BCH’s current multi-exahash level offers strong protection against such threats.
