The Ethereum Merge marked a historic shift from proof-of-work (PoW) to proof-of-stake (PoS), slashing energy consumption by 99%. But Ethereum’s evolution is far from over. Here’s a deep dive into the next phases: the Surge, Verge, Purge, and Splurge — upgrades poised to transform Ethereum into a scalable, decentralized, and ultra-efficient blockchain.
Key Takeaways
- Merge Impact: Ethereum now uses PoS, reducing ETH issuance by ~90% (a "triple halving") and enabling gas fee burns via EIP-1559.
- Future Upgrades: Parallel development of the Surge (sharding), Verge (Verkle trees), Purge (ledger pruning), and Splurge (miscellaneous optimizations).
- End Goal: Achieve 100k transactions per second (TPS), lower fees, and stateless validation for true decentralization.
The Merge Recap
Ethereum’s PoS transition:
- Energy Efficiency: 99% reduction in power usage.
- ETH Issuance: New formula (
166*√total ETH staked
) drastically cuts supply growth. - Fee Burning: EIP-1559 permanently removes ETH from circulation via gas fee burns.
This sets the stage for Ethereum’s next act.
Vitalik’s Roadmap: The Five Phases
1. The Surge: Scaling via Sharding
Problem: Mainnet congestion and high gas fees.
Solution:
- Introduce 64 shard chains to offload transactions from Layer 1 to Layer 2.
- Layer 2 rollups (e.g., Arbitrum, Optimism) bundle transactions, reducing costs by ~90%.
- Outcome: Target throughput of 100k TPS, enabling microtransactions for social/gaming use.
2. The Verge: Stateless Clients with Verkle Trees
Problem: Validators require massive storage for network state.
Solution:
- Replace Merkle trees with Verkle trees (smaller proofs).
- Enable stateless clients—validators need minimal data, lowering hardware requirements.
- Outcome: Decentralized validation via smartphones.
3. The Purge: Slimming the Ledger
Problem: Full nodes store 1TB+ of historical data.
Solution:
- EIP-4444: Nodes no longer need to archive the entire ledger.
- Outcome: Lighter nodes, faster sync times, and reduced operational costs.
4. The Splurge: Miscellaneous Upgrades
Catch-all for optimizations like:
- Account abstraction (smart contract wallets).
- MEV mitigation (fairer transaction ordering).
FAQs
Q1: When will Ethereum reach 100k TPS?
A: Post-Surge, estimated within 2–3 years as sharding rolls out.
Q2: How does Verge improve decentralization?
A: Stateless clients allow validation on low-power devices (even smartphones).
Q3: Will gas fees drop to zero?
A: No, but Layer 2 fees could fall to fractions of a cent.
Q4: Is Ethereum abandoning its mainnet?
A: No—mainnet remains the "spine" for Layer 2 security.
Conclusion
Ethereum’s post-Merge upgrades aim to resolve scalability trilemma tradeoffs: security, decentralization, and speed. While challenges remain, the roadmap signals Ethereum’s ambition to power Web3’s future.
