Ethereum Merge Series #02: PoS Transition Progress and Fork Narratives

01 Merger Progress and Ethereum’s Future Roadmap

Current Status and Historical Context

On July 14, Ethereum core developer Tim Beiko announced during a conference call that the Merge upgrade—shifting Ethereum’s consensus algorithm from PoW to PoS—is tentatively scheduled for September 19. The Merge won’t be instantaneous; it’s expected to unfold over 6+ months, completing fully by early 2023.

The PoS Beacon Chain, launched in December 2020, serves as the backbone for managing staking and coordinating future shard expansions. As of August 2022, over 13.88 million ETH (≈$190B) is staked, with 400,000+ validators participating (Source).

In January 2022, the Ethereum Foundation rebranded "ETH 2.0" to "Consensus Layer." The Merge will integrate the Beacon Chain (consensus layer) with the current mainnet (execution layer), finalizing the transition to PoS.

Why PoS?

The Merge slashes Ethereum’s energy consumption by 95%+ and enhances network security. Vitalik Buterin argues in "Why PoS?":

• PoW Attacks: Require minimal cost (renting GPUs to outpace miners).
• PoS Defense: Attacks incur massive capital loss—staking penalties automatically burn malicious actors’ ETH.

PoS also lays groundwork for shard chains, where validators are randomly assigned, reducing collusion risks to <1 trillion odds.

Ethereum’s Roadmap Post-Merge

1. The Merge: ETH becomes deflationary; energy use drops 99%.
2. The Surge (2023): Introduces sharding for scalability.
3. The Verge: Optimizes storage via Verkle trees.
4. The Purge: Reduces validator storage needs.
5. The Splurge: Ensures smooth post-upgrade operations.

These phases advance concurrently, aiming for 100,000 TPS.

02 The $190B Question: What’s Next for PoW Miners?

Options for GPU/ASIC Miners

1. Mine Other PoW Coins (e.g., ETC)

   • Challenges: ETC’s market cap is 1/50th of ETH’s; ROI dwindles as hash rate shifts.
   • Stats: ETC’s hash rate (25 TH/s) vs. ETH’s (924 TH/s) → 1:37 ratio.

2. Fork Ethereum

   • Complexity: Requires ecosystem-wide coordination (DeFi, NFTs, stablecoins).
   • Vitalik’s Warning: Centralized stablecoins (USDT/USDC) may sway fork outcomes.

3. Transition to Data Centers

   • Examples: Hut 8 and HIVE Blockchain repurpose GPUs for AI/cloud services.

4. Power Web3 Protocols

   • Render Network: Renders 3D/2D objects.
   • Livepeer: Decentralized video streaming.

5. Stake in PoS

   • Validators need 32 ETH; yields 7–13% APR.

FAQ Section

Q: Will ETH-PoW forks survive long-term?
A: Unlikely without developer/ecosystem support (see Ethereum Classic’s stagnation).

Q: What’s the most profitable post-Merge option for miners?
A: Repurposing GPUs for data centers or Web3 protocols offers sustainable ROI.

Q: How does PoS improve scalability?
A: Sharding + PoS enables parallel processing, boosting TPS 1000x.
