The Ethereum network has officially transitioned from Proof-of-Work (PoW) to Proof-of-Stake (PoS) consensus mechanism, marking the end of an era for ETH mining. This historic event—dubbed "The Merge"—was completed on September 15 at 2:43 PM UTC, rendering Ethereum mining difficulty and hashrate obsolete overnight.
The Dawn of a New Ethereum Era
After years of development and delays, Ethereum's Merge represents one of crypto's most ambitious technical achievements. Vitalik Buterin, Ethereum's co-founder, celebrated the milestone on Twitter:
This is a monumental moment for the Ethereum ecosystem. Everyone who contributed to the Merge should feel proud today.
Key impacts of the Merge include:
- 99.95% reduction in energy consumption
- Elimination of GPU/ASIC mining requirements
- Foundation for future scalability solutions like sharding

The Rise of Ethereum Classic (ETC)
With ETH mining now obsolete, displaced miners have flocked to Ethereum Classic—the original Ethereum blockchain that remained PoW after ETH's 2016 hard fork.
ETC Hashrate Reaches Record Highs
- 183.40 TH/s current hashrate (190% 24-hour increase)
- Mining profitability dropped 200% due to sudden influx
- Network difficulty adjusts automatically every 2 weeks
| Metric | Pre-Merge | Post-Merge | Change |
|-----------------|-----------|------------|---------|
| Hashrate | 63 TH/s | 183 TH/s | +190% |
| Mining Profit | $2.50/day | $0.80/day | -200% |
| Network Difficulty | Medium | Very High | 3x |Understanding Ethereum Classic's Origin
ETC exists due to Ethereum's controversial 2016 hard fork after The DAO hack. Key differences:
- ETC: Maintained original blockchain (PoW)
- ETH: New chain with rewritten transaction history

FAQs About The Merge and Mining Transition
1. Can I still mine Ethereum?
No—ETH mining has permanently ended. The network now validates transactions through staking.
2. Why are miners choosing ETC over other PoW coins?
ETC shares Ethereum's original codebase, making it the most familiar alternative for ETH miners.
3. Will ETC's price rise with increased mining activity?
Not necessarily—price depends on broader market factors beyond hashrate.
4. How long until ETC mining profitability stabilizes?
Typically 2-4 weeks as network difficulty adjusts to new hashrate levels.
5. What happens to unused ETH mining equipment?
Some repurposed for ETC, others sold or used for alternative computing tasks.
The Future of Proof-of-Work Mining
While Ethereum's transition leaves fewer major PoW chains, mining remains viable for:
- Bitcoin (BTC)
- Litecoin (LTC)
- Dogecoin (DOGE)
- Other smaller-cap PoW cryptocurrencies
Industry experts suggest the mining sector will undergo consolidation as less efficient operations become unprofitable.
