The Ethereum Merge, completed over a year ago, marked a historic shift from proof-of-work (PoW) to proof-of-stake (PoS) consensus. This upgrade introduced "staking" as a new method to validate transactions while addressing environmental concerns—but lingering challenges around centralization and infrastructure risks persist. Here’s an in-depth analysis of Ethereum’s post-Merge landscape:
1. Energy Consumption Plummets by 99.9%
Ethereum’s transition to PoS slashed its energy usage dramatically. Pre-Merge, the network consumed energy comparable to a small country due to power-hungry mining operations. Post-Merge:
- 99.9% reduction in energy use by eliminating mining rigs.
- Emissions now negligible, resolving earlier critiques from NFT/DeFi skeptics.
- Bitcoin (still PoW) consumes ~Singapore-level electricity annually (Cambridge Bitcoin Index).

2. Staking Centralization Emerges as a Critical Issue
While PoS lowered entry barriers, centralization risks intensified:
- 32 ETH (~$50K) required to run a validator node, limiting participation.
- Lido dominates with 32.3% of staked ETH—raising concerns over the 33% threshold that could compromise security.
- Intermediaries like Coinbase and Lido pool user funds, controlling disproportionate network influence.
3. MEV and Censorship Debates Intensify
Maximal Extractable Value (MEV) became a double-edged sword post-Merge:
- MEV-Boost (by Flashbots) optimizes validator profits but centralizes block production (~90% of blocks use it).
- Censorship risks: Flashbots once excluded Tornado Cash-related transactions, sparking neutrality debates.
- Recent fixes reduced Flashbots’ relay dominance to 17.3%, cutting censorship rates from 78% (2022) to 35%.
4. Liquid Staking Tokens (LSTs) Dominate ETH Markets
LSTs surged post-Shapella upgrade (enabling staked ETH withdrawals):
- $200B market: LSTs like Lido’s stETH (72.24% share) allow trading while earning staking yields.
- DeFi integration: LSTs solve liquidity lock-up issues, appealing to traders.

5. ETH Supply Turns Deflationary
Merge-induced tokenomics changes:
- EIP-1559 + Merge reduced ETH issuance, creating net deflation (-0.24% supply YOY).
- Price impact muted: Macro factors overshadowed supply effects short-term.
FAQs
Q: How does PoS differ from PoW?
A: PoW relies on competitive mining; PoS selects validators randomly based on staked ETH, cutting energy use.
Q: Is Ethereum now fully decentralized?
A: No—staking pools like Lido consolidate power, posing centralization risks.
Q: Can MEV be eliminated?
A: Unlikely, but solutions like MEV-Boost aim to minimize exploitation while facing neutrality critiques.
Q: Are LSTs safer than traditional staking?
A: They offer liquidity but introduce smart contract risks (e.g., de-pegging).
Q: Will ETH’s deflationary model boost its price?
A: Long-term potential exists, but short-term price action depends more on market conditions.
Key Takeaways: Ethereum’s Merge achieved its sustainability goals but exposed trade-offs in decentralization and MEV governance. The network’s next phase must address these gaps to fulfill its decentralized vision.
