What is Hashrate and How is it Measured?
Hashrate represents the computational power of mining hardware, measured in solutions (hashes) per second. In the Bitcoin Cash network, mining performance is quantified as h/s (hashes per second). Here's how the units scale:
- 1 Kh/s = 1,000 h/s
- 1 Mh/s = 1,000 Kh/s = 1,000,000 h/s
- 1 Gh/s = 1,000 Mh/s = 1,000,000,000 h/s
- 1 Th/s = 1,000 Gh/s = 1,000,000,000,000 h/s
For context, a single Nvidia 1070 Ti GPU mines at 340 MH/s, performing 340 million hash calculations per second.

Understanding Hash Functions and Mining Solutions
What Constitutes a Mining Solution?
Each hash calculation represents one attempt to solve the cryptographic puzzle set by the Bitcoin Cash algorithm. Mining is essentially a high-speed guessing game where miners:
- Continuously compute hash functions.
- Search for a valid block solution.
- Once found, the network resets the puzzle, restarting the process.
Key Insight: The "solution" is the correct hash that meets the blockchain's difficulty criteria, allowing a new block to be added.
Bitcoin Cash Network Hashrate: Definition and Calculation
What is Network Hashrate?
The BCH network hashrate (currently 3.48 EH/s) aggregates the total mining power of all participants. This metric is derived from:
- Network difficulty: Adjusts to maintain consistent block times.
- Average block discovery time: Typically targeted at 10 minutes for BCH.
- Recent block data: Real-world mining performance metrics.

FAQ: Bitcoin Cash Mining Essentials
Q1: Why does network hashrate fluctuate?
A1: It changes as miners join/leave the network or upgrade/downgrade equipment.
Q2: How does hashrate affect mining rewards?
A2: Higher hashrate increases competition, reducing individual miner rewards unless offset by higher hardware efficiency.
Q3: Can I mine BCH with a home GPU?
A3: While possible, profitability is limited due to high network hashrate; ASICs dominate BCH mining.
Q4: Where can I track real-time BCH hashrate?
A4: Use blockchain explorers or mining pools like 2Miners for live metrics.
