Introduction
As mid-2022 approaches, Ethereum 2.0 upgrades reach a critical milestone. The Ropsten testnet is set to undergo "The Merge," marking a pivotal step toward transitioning Ethereum from Proof-of-Work (PoW) to Proof-of-Stake (PoS).
Key Developments
- Ropsten Testnet Merge: The terminal total difficulty (TTD) is set at
50000000000000000, with the merge expected around June 8–9, barring unexpected hash rate fluctuations. - Consensus Shift: The merge combines Ethereum’s Beacon Chain (consensus layer) with its existing execution layer, eliminating PoW but not reducing Gas fees.
- Mainnet Timeline: No official date yet. Post-Ropsten, two additional testnets (Goerli and Sepolia) will transition before focus shifts to the mainnet.
"Mainnet merge dates can’t be confirmed until after Goerli and Sepolia transitions," emphasized Ethereum core developer Tim Beiko.
Ethereum 2.0 Upgrade Phases
The upgrade is a multi-phase process:
| Phase | Description | Status |
|-------------|-------------------------------------------------------------------------------------------------|--------------------|
| Phase 0 | Beacon Chain launch (Dec 2020). Introduces PoS consensus via staking (~10.53% of ETH staked). | ✅ Operational |
| Phase 1 | Sharding trials (data layer). Focuses on structural testing, not scalability. | ⏳ Pending |
| Phase 2 | eWASM integration (execution layer). Enables smart contracts, transfers, and full functionality.| ⏳ Pending |
| Phase 3 | Optimization and fine-tuning. | ⏳ Pending |

Market and Miner Impact
- ETH Price: Down 65% from its peak ($4,868), trading at **$1,755** (OKX data).
- Miner Revenue: Dropped 27.2% in May ($969.4M), with transaction fees contributing just 5.6%. EIP-1559 has burned 2.41M ETH to date.
- Hash Rate: Despite the impending merge, Ethereum’s hash rate remains near all-time highs as miners capitalize on final PoW rewards.
Stakeholder Perspectives
For Holders:
- No action required post-merge. ETH holdings remain unchanged.
- No new tokens or migrations needed.
Controversies:
- 2Miners Pool Critique: Argues PoS reduces decentralization (32 ETH minimum stake vs. GPU mining’s low entry cost) and risks security.
- PoS Concerns: Potential for fraudulent staking platforms, echoing risks like LUNA’s collapse.
"PoS is Ethereum’s biggest mistake," claims 2Miners, citing centralization and security flaws.
FAQs
1. When will Ethereum’s mainnet merge happen?
No confirmed date. Developers await successful transitions on Goerli and Sepolia testnets first.
2. Will Gas fees decrease after the merge?
No. Gas fees are tied to network demand, not consensus mechanisms.
3. How does PoS affect miners?
PoW mining ends, eliminating GPU-based revenue. Miners must transition to staking or other chains.

Conclusion
The Ethereum 2.0 merge is a landmark shift toward sustainability and scalability, yet challenges around decentralization and security persist. As the crypto community watches closely, Ethereum’s evolution will shape the future of blockchain technology.
