Ethereum's Post-Merge Performance and the Case for Institutional Adoption
Ethereum's journey since the Merge in 2022 has been nothing short of transformative. By shifting from proof-of-work to proof-of-stake, EthereumETH-- slashed energy consumption by 99.95%, aligning with environmental sustainability goals while fortifying network security through over 1 million active validators staking 36 million ETH—nearly a third of the total supply [1]. But the Merge was just the beginning. Over the past three years, Ethereum has rolled out a series of technical upgrades—Shapella, Dencun, Pectra, and the upcoming Fusaka—that have redefined its scalability, usability, and institutional appeal. These upgrades are not just incremental improvements; they are foundational shifts that position Ethereum as a robust, enterprise-grade blockchain.
The Pectra Upgrade: A Catalyst for Institutional Staking
The Pectra upgrade in May 2025 marked a pivotal milestone. By increasing the validator staking limit from 32 ETHETH-- to 2,048 ETH, it streamlined operations for large stakers, reducing the overhead of managing multiple validators and lowering costs for institutions [3]. This change, encapsulated in EIP-7251, directly addresses the operational complexity that had previously deterred institutional participation. For example, BlackRockBLK-- and UBSUBS-- have already deployed on-chain strategies leveraging this flexibility, enabling them to allocate capital more efficiently while maintaining decentralization [1].
Additionally, Pectra introduced account abstraction via EIP-7702, allowing smart contract wallets with features like multisig and social recovery. This innovation is critical for institutional-grade security and compliance, enabling custodians to manage assets with granular control and auditability [3]. The upgrade also expanded data blob capacity per block from 3 to 6, enhancing Layer 2 (L2) scalability and reducing transaction costs by 90%—a boon for DeFi and NFT platforms [1].
Fusaka: Scaling for the Future
Scheduled for November 2025, the Fusaka upgrade will further cement Ethereum's scalability. PeerDAS (EIP-7594) will allow validators to sample data availability without downloading entire datasets, slashing bandwidth requirements and improving L2 performance [4]. This is particularly significant for rollups like ArbitrumARB-- and Optimism, which rely on efficient data availability to maintain throughput. Fusaka also includes EIP-7935, which increases the gas limit from 30 million to 150 million, enabling more transactions per block and reducing congestion [4].
For institutions, these upgrades mean Ethereum can now rival traditional financial infrastructure in terms of speed and cost. As one industry analyst notes, “Fusaka's optimizations will make Ethereum the go-to base layer for enterprises seeking blockchain solutions without compromising on decentralization” [5].
Institutional Adoption: Metrics and Momentum
The technical upgrades have directly fueled institutional adoption. Ethereum's Total Value Locked (TVL) surged to $90 billion by July 2025, representing 60% of the DeFi ecosystem's total TVL [5]. This growth is driven by reduced L2 fees (down 90% post-Dencun) and the introduction of staked Ethereum ETFs, which saw $907.99 million in weekly inflows in July 2025 [2].
Regulatory tailwinds have further accelerated adoption. The U.S. SEC's approval of in-kind creation/redemption for Ethereum ETFs and the exemption of stETH from securities rules have made Ethereum a more accessible asset class [5]. As a result, spot Ethereum ETFs now hold $20.11 billion in net assets, with $5.43 billion in net inflows recorded in July 2025 alone [3].
Challenges and the Road Ahead
Despite these gains, challenges persist. The increased validator staking limit in Pectra raises centralization risks, as larger entities may dominate staking pools [1]. Additionally, Ethereum faces competition from SolanaSOL-- and BNBBNB-- Chain, which offer faster transaction speeds. However, Ethereum's focus on L2 interoperability and post-quantum cryptography (via Fusaka) positions it to address these threats [4].
Conclusion
Ethereum's post-Merge technical upgrades have created a flywheel effect: improved scalability attracts developers and users, which in turn drives institutional adoption. With Pectra and Fusaka addressing both operational efficiency and long-term security, Ethereum is no longer just a speculative asset—it's a foundational infrastructure for the next era of finance. For institutions, the case is clear: Ethereum's technical roadmap aligns with the demands of modern capital markets, making it a compelling long-term investment.
