Now that Ethereum has successfully completed the Merge, the blockchain enters a new era defined by sustainability, scalability, and long-term decentralization. The transition from proof-of-work (PoW) to proof-of-stake (PoS) wasn’t just a milestone—it was the foundation for a broader roadmap aimed at transforming Ethereum into a high-performance, energy-efficient, and globally accessible decentralized platform.
This article explores what comes after the Merge, detailing Ethereum’s upcoming upgrades—collectively known as the Surge, Verge, Purge, and Splurge—and how they will shape the future of Web3.
The Merge: A Recap of Ethereum’s PoS Transition
The Merge marked one of the most significant events in blockchain history. By shifting Ethereum from PoW to PoS, the network achieved a 99% reduction in energy consumption, making it one of the most environmentally sustainable blockchains at scale.
Beyond environmental benefits, the Merge fundamentally altered Ethereum’s economic model:
- Reduced ETH issuance: Validators now receive lower rewards than miners did under PoW. Annual ETH issuance is projected to drop dramatically—from 5 million ETH per year to a dynamic rate based on staking participation (calculated via 166 × √total ETH staked).
- Deflationary pressure via EIP-1559: Since August 2021, Ethereum has implemented a fee-burning mechanism. Every transaction fee (or "gas fee") is partially burned, removing ETH from circulation. Combined with reduced issuance, this could make Ethereum net deflationary during periods of high network usage.
Some analysts have likened this dual mechanism—lower supply growth and active coin destruction—to a "triple halving," far exceeding Bitcoin’s periodic reward cuts in long-term scarcity impact.

But the Merge was never the end goal. It was the necessary first step toward a much more ambitious vision.
The Road Ahead: Ethereum’s Four-Part Upgrade Roadmap
Vitalik Buterin and the Ethereum development community have outlined a multi-phase plan to scale and strengthen the network. These phases—the Surge, Verge, Purge, and Splurge—are not strictly sequential; many will be developed in parallel to accelerate progress.
Let’s break down each phase and what it means for users, developers, and the broader Web3 ecosystem.
The Surge: Scaling Through Sharding
Ethereum’s biggest usability challenge has been congestion. High demand for DeFi, NFTs, and token launches has driven gas fees skyward, pricing out everyday users.
Rather than increasing block size (like some competing chains), Ethereum is pursuing off-chain scaling via Layer 2 solutions—rollups, sidechains, and soon, native shards.
With the Surge, Ethereum will introduce 64 new shard chains. These are independent data layers designed to distribute transaction load across the network. Each shard will process its own set of data, which is then batched and anchored back to the mainnet for final settlement.
Key benefits include:
- Massive throughput increase: Projected capacity could reach up to 100,000 transactions per second (TPS)—a 6,600x improvement over current levels.
- Dramatically lower costs: With more data space available, Layer 2 transaction fees could drop by up to 90%, potentially falling below $0.01.
- Enhanced accessibility: Cheap transactions open doors for microtransactions in gaming, social media, and IoT applications.
Today’s Layer 2 ecosystem already includes major players like Arbitrum, Optimism, and Polygon. Post-Surge, these platforms will integrate more seamlessly with Ethereum’s core protocol, creating a unified, scalable stack.

The Verge: Enabling Stateless Clients with Verkle Trees
As Ethereum scales, node requirements must shrink—not grow. That’s where the Verge comes in.
Currently, validating Ethereum transactions requires storing and processing vast amounts of network state using Merkle trees. This demands powerful hardware, limiting who can run a node.
The Verge introduces Verkle trees, a more efficient cryptographic structure that allows validators to verify transactions using minimal data. This enables stateless clients—nodes that can validate without holding the full state of the network.
Implications:
- Lower hardware barriers: Validators could run on laptops or even smartphones.
- Greater decentralization: More participants = stronger censorship resistance.
- Faster synchronization: New nodes join the network quicker.
This upgrade is critical for maintaining Ethereum’s decentralized ethos as it scales globally.
The Purge: Reducing Network Bloat
Even if nodes don’t need to store current state (thanks to Verkle trees), they still carry the full historical record of Ethereum—a ledger now exceeding 1 terabyte in size.
The Purge aims to solve this through proposals like EIP-4444, which removes the requirement for nodes to store historical data indefinitely. Instead, old blocks can be pruned or archived off-chain.
Benefits include:
- Reduced storage demands for node operators.
- Faster sync times and improved client performance.
- Lower operational costs—making home-baked staking more accessible.
Ultimately, The Purge ensures that running an Ethereum node remains feasible for individuals—not just institutional players with server farms.
The Splurge: Polishing the Protocol
“The Splurge” sounds whimsical, but it’s serious business. It’s a catch-all term for smaller yet impactful upgrades that enhance usability, security, and efficiency across the stack.
Potential components include:
- Improvements to consensus mechanics.
- Enhancements to account abstraction (e.g., ERC-4337).
- Better tooling for developers and wallet integrations.
- Optimization of cross-shard communication.
While less flashy than sharding or statelessness, these tweaks are essential for delivering a smooth user experience at scale.

Frequently Asked Questions (FAQ)
Q: What comes after the Ethereum Merge?
After the Merge, Ethereum is progressing through four major upgrade phases: the Surge (scaling via sharding), the Verge (stateless clients), the Purge (data pruning), and the Splurge (miscellaneous optimizations). Together, they aim to make Ethereum faster, cheaper, and more decentralized.
Q: Will Ethereum become faster after these upgrades?
Yes. Current throughput is around 15 TPS. After full implementation of the Surge and related upgrades, Ethereum could handle up to 100,000 TPS, rivaling centralized payment systems in speed while remaining decentralized.
Q: Can I run an Ethereum node on my phone?
Eventually, yes. Thanks to Verkle trees (The Verge) and data pruning (The Purge), future Ethereum clients may be lightweight enough to run on smartphones—bringing true decentralization to mobile users.
Q: Is Ethereum becoming deflationary?
It already has periods of deflation. With EIP-1559 burning transaction fees and reduced issuance post-Merge, when network activity is high, more ETH is burned than issued—resulting in a net decrease in supply.
Q: How do Layer 2 solutions benefit from upcoming upgrades?
Layer 2 rollups will gain greater data availability through sharding (Surge), enabling cheaper and faster transactions. This strengthens their role as the primary interface for most Ethereum users while preserving security via mainnet settlement.
Q: Are all upgrades happening at once?
Many are being developed in parallel to accelerate progress. However, deployment will occur incrementally based on testing and network readiness.
Final Thoughts: Ethereum’s Journey Has Just Begun
The Merge was historic—but it was only the beginning. With the Surge, Verge, Purge, and Splurge on the horizon, Ethereum is evolving into a truly scalable, sustainable, and user-friendly platform.
These upgrades aren’t just technical improvements—they’re foundational shifts that could enable blockchain technology to power everyday digital interactions: social networks, games, identity systems, and more.
As development continues, now is the time to understand not just what Ethereum is, but what it’s becoming.
