The evolution of blockchain technology has reached a pivotal stage, with Ethereum standing at the forefront of innovation and adoption. As the world's leading smart contract platform, Ethereum continues to shape the future of decentralized applications (dApps), DeFi, and Web3. With the successful transition to Ethereum 2.0 and ongoing Layer 2 (L2) advancements, the network is becoming more scalable, secure, and sustainable. In this deep dive, we explore key insights from Justin Drake, a core contributor at the Ethereum Foundation (EF), and Owen, OKX Web3 Product Lead, on Ethereum’s technical progress, ecosystem growth, and long-term vision.
Ethereum and Layer 2 Post-Cancun Upgrade
The Cancun-Deneb upgrade marked a transformative moment for Ethereum, significantly enhancing scalability through proto-danksharding—a precursor to full sharding. This upgrade introduced blob transactions, drastically reducing data storage costs for L2 rollups.
👉 Discover how Ethereum’s latest upgrades are reshaping Web3 scalability.
According to Justin Drake, the impact has been immediate:
- Transaction throughput on Ethereum has increased.
- L2 gas fees have dropped substantially, making micro-transactions economically viable.
- Data usage reflects strong adoption: Dune analytics show average blob usage per block rising from ~1 in March to 2.3 blobs/block, with a target of 3 blobs/block soon.
From an economic standpoint, this expansion in supply (S1 → S2) lowers equilibrium prices (P1 → P2), stimulating demand (Q1 → Q2). The result? More users, more dApps, and a healthier ecosystem.
Owen adds that while overall transaction volume hasn’t exploded, capital is clearly shifting to L2s:
- Base: +560% in daily active users (DAUs), +540% in daily transactions (DTXs)
- Optimism: +70% DTXs
- Arbitrum: +200% DTXs
This trend indicates that lower fees are attracting retail users and small traders, driving real-world usage.
Ethereum Foundation’s Role: Promoting Decentralization Through ETH Reduction
A common misconception is that the Ethereum Foundation (EF) centrally controls the network. In reality, EF’s role is increasingly minimal—by design.
Justin Drake outlines EF’s current responsibilities:
- Hosting developer events like Devcon
- Maintaining Geth (one of five execution clients)
- Providing unconditional grants to community projects
- Facilitating coordination calls (e.g., All Core Devs, MEV-boost)
- Conducting foundational research
- Supporting roadmap development
Notably, EF’s ETH holdings are steadily decreasing due to funding disbursements. Currently, EF controls just 0.23% of total ETH supply—a number expected to trend toward zero over decades.
This deliberate reduction strengthens network decentralization, ensuring no single entity holds undue influence.
Owen emphasizes that EF should evolve into a technical advisory body, not a governing force. As the ecosystem matures, open, community-driven discourse becomes more important than centralized leadership—aligning perfectly with blockchain’s ethos of transparency and shared ownership.
DeFi and Future Mass-Adoption Use Cases
Decentralized Finance (DeFi) remains one of Ethereum’s strongest value propositions.
Justin Drake forecasts a 10x growth in DeFi over the next five years, driven by:
- Stablecoins: Aiming for $1 trillion in issuance, with strong demand for decentralized options
- DEXs: Continued rise in trading volume share vs. centralized exchanges
- Lending protocols (e.g., Aave, Compound): Expected 10x growth
- Prediction markets (e.g., Polymarket): Growing mainstream interest
- Derivatives: Liquid perps, options, and futures on-chain
Beyond DeFi, ENS and IPFS-powered decentralized frontends will become standard, reducing reliance on centralized servers.
However, high transaction fees remain a barrier. As Owen notes, executing one transaction on Ethereum L1 could fund dozens on L2s. This efficiency gap drives user behavior toward rollups.
To bridge Web2 and Web3 experiences, innovations like EIP-4337 (Account Abstraction) are critical. It enables:
- Social recovery of wallets
- Paying gas in non-native tokens
- Simplified onboarding

These upgrades lay the foundation for mass adoption, where average users can self-custody assets seamlessly—just like using traditional apps.
Key Technological Advances: Staking, Restaking & EIP-7702
Two major innovations define Ethereum 2.0’s current phase: staking and restaking.
With Proof-of-Stake (PoS), Ethereum slashed energy consumption by over 99%. But beyond sustainability, staking enables economic security sharing—where protocols like EigenLayer allow restaking of ETH to secure new services.
Only Ethereum’s scale and decentralization make this possible.
Additionally, Vitalik Buterin’s EIP-7702 proposes upgrading externally owned accounts (EOAs) to support smart contract functions temporarily. This enhances flexibility without sacrificing security—further lowering entry barriers for new users.
Proof-of-Stake and Decentralization: A Realistic Perspective
Critics argue PoS favors wealthy stakeholders. But Owen counters with real-world context:
- PoW mining was already centralized: Top 5 pools controlled >75% of hashrate.
- Geopolitical risks emerged (e.g., China’s 2021 mining ban halved Bitcoin’s hashrate).
- Hardware dependence (e.g., GPUs) created supply-chain vulnerabilities (e.g., NVIDIA throttling mining performance).
In contrast, PoS:
- Lowers hardware barriers
- Enables global participation
- Reduces environmental impact
To protect small validators:
- Verkle Trees + EIP-4444 reduce disk space requirements
- Light clients become more viable
- Future proposals may lower minimum staking thresholds
These improvements promote fairness and long-term decentralization.
Layer 2 Landscape & Rollup Technology Potential
While L2s solve scalability, their rapid proliferation has led to liquidity fragmentation and UX fragmentation.
Owen observes:
- Too many L2s compete for users, undermining the goal of unified scaling.
- Headline chains (Arbitrum, Optimism, Base) capture most activity; others risk obsolescence.
- Users struggle with disjointed interfaces across chains.
Solutions are emerging:
- Chain abstraction: Enables seamless cross-chain interaction via atomic swaps
- Aggregation layers (e.g., Polygon AggLayer) aim to unify L2s into a single logical chain
Rollups offer compelling advantages:
- High throughput and low fees
- Security inherited from Ethereum
- Full EVM compatibility
- Innovation-friendly environments
Yet challenges persist:
- Data availability constraints
- Withdrawal delays (challenge periods)
- Partial incompatibilities between rollups
- Centralization risks in sequencer nodes
Despite drawbacks, rollups remain essential to Ethereum’s scaling roadmap.
Security, Governance, Energy Efficiency & Privacy in Ethereum 2.0
Security Challenges
- Whale attacks: Large stakers could collude.
- Concentration risk: Liquid staking pools (e.g., Lido) dominate validator sets.
- Sharding complexity: New attack vectors may emerge.
- Economic incentives: Attack profitability must remain lower than slashing penalties.
- Smart contract risks: EVM changes may break backward compatibility.
Governance Evolution
Post-PoS, governance is shifting toward token-weighted participation. However, social consensus remains vital. As L2s grow, governance must adapt to include cross-layer coordination.
Energy Efficiency
PoS reduced energy use by 99.95%. Further gains will come from:
- Transitioning from Merkle Patricia Trees to Verkle Trees
- Stateless client architectures
Privacy Roadmap
Future privacy enhancements include:
- Wider adoption of zero-knowledge proofs
- Development of quantum-resistant cryptography
- Balancing regulatory compliance with user anonymity
Long-Term Outlook: Challenges Over 10 and 30 Years
In the next decade, Ethereum’s biggest challenge will be reducing friction between L1 and L2s, creating a unified user experience akin to a single chain.
Over 30 years, Ethereum is poised to remain relevant due to its unmatched decentralization, longevity, and developer momentum—even as newer chains emerge.
