Ethereum remains the cornerstone of decentralized innovation, powering everything from decentralized finance (DeFi) to non-fungible tokens (NFTs) and the broader Web3 ecosystem. Yet, its dominance isn’t guaranteed — it must continuously evolve to meet rising demand, improve scalability, and preserve decentralization. At the heart of this transformation is Vitalik Buterin, whose strategic shift from operational leadership to long-term research is redefining Ethereum’s future.
This article explores Ethereum’s upcoming upgrades — Pectra, Fusaka, and the Glamsterdam update — while unpacking Buterin’s deeper vision for a more scalable, private, and resilient blockchain. We’ll also examine how these changes fit into Ethereum’s six-phase evolution and what they mean for developers, users, and the future of smart contract platforms.
Why Ethereum Upgrades Matter
Ethereum upgrades are essential to scale, secure, and evolve the network without compromising its decentralized foundation.
Since its launch in 2015, Ethereum has undergone 16 major upgrades, each addressing critical challenges in performance, security, and usability. The most pivotal was the Merge in 2022, which transitioned Ethereum from energy-intensive proof-of-work (PoW) to sustainable proof-of-stake (PoS). This shift laid the groundwork for a more efficient and environmentally friendly blockchain.
But the work doesn’t stop there. As global demand grows, Ethereum faces persistent issues:
- Scalability bottlenecks leading to network congestion
- High gas fees during peak usage
- Clunky user onboarding deterring mainstream adoption
- Centralization risks in staking and infrastructure
To remain the leading smart contract platform, Ethereum must continuously innovate. Its development roadmap — spanning from Pectra to Fusaka and beyond — isn’t just a series of technical patches. It’s a strategic blueprint to transform Ethereum into a high-throughput, low-cost, and truly decentralized global settlement layer.

Vitalik Buterin’s Evolving Role in Ethereum’s Future
Vitalik Buterin has shifted his focus entirely to long-term research, driving innovation in scalability, privacy, and decentralization.
In 2024, Buterin stepped back from day-to-day operations at the Ethereum Foundation to concentrate on foundational research. This move allows him to tackle the most complex challenges facing Ethereum’s long-term sustainability.
His current research priorities include:
- Scaling for billions: Designing architectures that can support global user adoption without sacrificing security.
- Protocol-level privacy: Introducing features like stealth addresses and private transactions by default.
- Decentralized consensus models: Ensuring that no single entity or group gains disproportionate control over validation or transaction ordering.
Buterin’s early vision for Ethereum — proposed when he was just 19 — centered on creating a programmable blockchain beyond Bitcoin’s limitations. Today, his focus is on ensuring that programmability doesn’t come at the cost of decentralization.
This shift reflects a maturing ecosystem: while core upgrades are now managed by a robust developer community, Buterin serves as Ethereum’s chief architect, exploring radical ideas like RISC-V-based virtual machines and modular consensus designs that could redefine the platform by 2030.
Ethereum’s Six-Phase Evolution: From Merge to Splurge
Ethereum’s development is structured across six conceptual phases, each solving a foundational challenge in blockchain design.
The Merge
Completed in 2022, this phase replaced PoW with PoS, reducing energy consumption by over 99% and enabling a more secure, validator-driven network.
The Surge
Focused on scaling through rollups and data availability, this phase includes EIP-4844 (proto-danksharding) and PeerDAS — technologies designed to drastically reduce L2 costs and increase throughput toward 100,000 transactions per second.
The Scourge
Aims to mitigate maximal extractable value (MEV) and centralization in staking. Solutions like enshrined proposer-builder separation (ePBS) ensure fairer transaction ordering and prevent validator dominance.
The Verge
Introduces Verkle Trees and SNARK-based light clients, enabling stateless verification and making it easier for low-power devices to participate in consensus.
The Purge
Simplifies the protocol by pruning historical data (via EIP-4444), reducing node storage requirements and improving long-term sustainability.
The Splurge
A catch-all phase for incremental improvements, including the Ethereum Object Format (EOF), cryptographic experiments, and UX enhancements like account abstraction.
These phases collectively form a cohesive roadmap toward a modular, scalable, and sustainable Ethereum.
The Pectra Upgrade: A Foundation for the Next Decade
The Pectra upgrade, scheduled for May 2025, merges two major upgrade tracks and introduces key features for smarter contracts and better UX.
Pectra combines the Prague (execution layer) and Electra (consensus layer) upgrades into a single hard fork. It delivers over a dozen Ethereum Improvement Proposals (EIPs) that enhance security, efficiency, and developer flexibility.
Key Features in Pectra:
- EIP-2537: Adds BLS12-381 precompiles, accelerating zero-knowledge proofs and boosting ZK-rollup performance.
- EIP-7002: Enables triggerable validator exits via the execution layer, improving staking flexibility.
- EIP-7702: Advances account abstraction by allowing externally owned accounts (EOAs) to act like smart contracts — paving the way for social recovery wallets and gasless transactions.
- EIP-7840: Optimizes blob storage scheduling, preparing for higher data throughput.
- EIP-6110 & EIP-7685: Streamline deposit processing and cross-layer communication.
Together, these upgrades introduce the Ethereum Object Format (EOF) — a modular contract structure that simplifies auditing, reduces runtime errors, and supports future protocol innovations.
While the official Pectra Ethereum release date is set for May 2025, final timing depends on testnet stability and community consensus.

What Comes After Pectra: Fusaka and Glamsterdam
Fusaka and Glamsterdam represent the next leap in Ethereum’s scalability and efficiency journey.
Fusaka (Osaka-Fulu)
Fusaka introduces PeerDAS (Peer Data Availability Sampling), a breakthrough that allows nodes to verify data availability without downloading entire blocks. This enables lighter clients, reduces bandwidth demands, and supports massive scaling for rollups.
By decentralizing data verification, Fusaka ensures that even low-resource devices can securely participate in the network — a critical step toward true decentralization at scale.
Glamsterdam (Amsterdam–G-Star)
Still in early design stages, Glamsterdam focuses on gas optimizations and protocol efficiency. It aims to make complex operations — especially those involving L2 rollups and ZK proofs — faster and cheaper.
Glamsterdam will refine execution logic, reduce overhead, and improve interaction between L1 and L2 layers. This upgrade is essential for supporting advanced dApps in gaming, identity, and decentralized AI.
Buterin’s Long-Term Research: Beyond the Roadmap
Buterin is exploring radical new architectures that could redefine Ethereum’s future beyond 2030.
While current upgrades focus on incremental improvements, Buterin is researching transformative ideas:
- Post-EVM architectures: Investigating RISC-V as a potential successor to the Ethereum Virtual Machine (EVM), offering better performance, modularity, and hardware compatibility.
- Decentralized scaling: Advancing light client protocols and rollup interoperability to ensure L2s remain trust-minimized.
- Privacy-by-default: Advocating for native privacy features that protect user data without compromising transparency or compliance.
These research directions may not appear in near-term upgrades but could shape Ethereum’s next evolutionary leap — one where scalability, privacy, and decentralization coexist seamlessly.
