Understanding the Ethereum PoW (ETHW) network hashrate is essential for anyone involved in cryptocurrency mining or blockchain technology. After the Ethereum network transitioned to proof-of-stake, a community-driven fork preserved the original proof-of-work mechanism, giving rise to Ethereum PoW (ETHW). This guide dives into what network hashrate means, how it's measured, and why it matters for miners and investors alike.
Whether you're running a single GPU rig or managing a large-scale mining operation, grasping the fundamentals of hashrate helps you optimize performance and make informed decisions. Let’s explore the core concepts behind Ethereum PoW network hashrate and its implications.
What Is Hashrate? How Is It Measured?
Hashrate refers to the computational power used in cryptocurrency mining. It measures how many cryptographic calculations—called hashes—a mining device can perform per second. In the Ethereum PoW (ETHW) network, each hash represents one attempt to solve a complex mathematical problem required to validate transactions and mine new blocks.
The unit of measurement is hashes per second (h/s), with larger values expressed using metric prefixes:
- 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, modern GPUs like the NVIDIA GeForce RTX 3070 can achieve around 60 Mh/s when mining ETHW, while high-end ASICs or optimized GPU farms operate at several Gh/s or even Th/s levels. The higher the hashrate, the greater the chances of successfully mining a block and earning rewards.

How Does Your GPU Contribute to Network Hashrate?
Every miner participating in the Ethereum PoW ecosystem contributes their hardware's hashrate to the total network power. For example, an NVIDIA GTX 1070 Ti typically delivers about 31 Mh/s, according to mining profitability calculators. This means it performs 31 million hash calculations every second in pursuit of finding a valid block.
Each hash is the result of running the Ethash algorithm—a memory-hard proof-of-work function designed to resist ASIC dominance and promote decentralized GPU mining. Miners repeatedly input slight variations into this function until they find a solution that meets the current network difficulty target.
Mining is essentially a race: thousands of devices worldwide are simultaneously solving the same puzzle. The first to find a correct hash broadcasts it to the network for verification. Once confirmed, the miner receives block rewards (in ETHW), and the process begins anew with a fresh challenge.
This decentralized competition ensures security and fairness across the network. As more miners join, the collective hashrate increases—leading to adjustments in mining difficulty to maintain consistent block times.
What Is Network Hashrate? Why Does It Matter?
The Ethereum PoW (ETHW) network hashrate represents the combined computational power of all active miners on the blockchain. At the time of writing, the total network hashrate stands at approximately 19.61 TH/s, or over 19.6 trillion hashes per second.
This figure isn't directly measured but calculated using two key variables:
- Current Network Difficulty – A dynamic value that adjusts based on how quickly blocks are being mined.
- Average Block Time – Ethereum PoW targets a block time of around 13–15 seconds.
Using these inputs, the network estimates total hashrate with the formula:
Hashrate ≈ (Difficulty × Hashes per Solution) / Average Block Time
A rising network hashrate indicates growing miner participation and enhanced blockchain security. Conversely, a sharp drop might signal reduced confidence or large-scale miner exits.
High network hashrate makes the chain more resistant to attacks (like 51% attacks), as an attacker would need immense resources to overpower the majority of honest miners.
Key Factors Influencing ETHW Network Hashrate
Several factors drive changes in Ethereum PoW’s overall hashrate:
1. Cryptocurrency Market Price
When ETHW price rises, mining becomes more profitable, attracting more participants and increasing total hashrate.
2. Electricity and Operational Costs
Regions with low electricity costs tend to host larger mining operations, contributing disproportionately to global hashrate distribution.
3. Hardware Availability and Efficiency
Advancements in GPU efficiency and availability of used graphics cards influence how many miners can participate profitably.
4. Fork Events and Community Support
The initial surge in ETHW hashrate followed the Ethereum merge in 2022, as miners migrated from the legacy chain. Ongoing community development and exchange listings help sustain interest.
5. Mining Pool Distribution
Large pools like 2Miners aggregate individual miner power, creating concentrated sources of hashrate. Monitoring pool dominance helps assess decentralization health.
Frequently Asked Questions (FAQ)
Q: What was the original Ethereum PoW network hashrate after the fork?
A: Immediately after the Ethereum merge in September 2022, ETHW started with a hashrate exceeding 35 TH/s, largely fueled by displaced miners seeking alternative chains.
Q: Why did ETHW hashrate decline from its peak?
A: As profitability fluctuated and some miners shifted to other coins or shut down operations due to economic conditions, the total hashrate gradually decreased to current levels (~19.61 TH/s).
Q: Can I check real-time ETHW network hashrate?
A: Yes—blockchain explorers and mining pool dashboards (such as those provided by 2Miners) offer live updates on network difficulty, hashrate, and block statistics.
Q: Does higher hashrate mean higher transaction fees?
A: Not directly. Transaction fees depend on network congestion and demand for block space. However, a stable high hashrate improves network reliability and security.
Q: Is ETHW still mineable with GPUs?
A: Absolutely. ETHW uses the Ethash algorithm, which remains GPU-friendly and ASIC-resistant—making it accessible for individual miners using consumer-grade hardware.
