TL;DR

• Upgrade Background: The competition among public chains has shifted to "real financial capacity competition," requiring faster, more stable, cheaper, and more predictable solutions.
• Ethereum Mainline: Through the Glamsterdam and Hegotá upgrades, it reshapes the capability boundaries of L1, moving from "the safest settlement layer" to "a higher performance financial foundation."
• Solana Mainline: Through the Alpenglow and Firedancer upgrades, it addresses shortcomings, helping Solana transition from "the fastest transaction chain" to "a more reliable global settlement candidate layer."
• Route Comparison: Ethereum is proving that "the most stable system can also be fast enough," while Solana is proving that "the fastest system can also be stable enough."
• Conclusion and Outlook: 2026 is not the endgame, but an open qualification round, where the outcome depends on the final direction of stablecoins, RWA, and on-chain capital.

The current competition among public chains is no longer about "whose story is bigger, whose community is livelier," but rather "who can maintain reliability in the face of real financial flows." As institutional funds begin to treat on-chain as a new clearing track, and when stablecoins, RWA, and high-frequency trading applications truly require 24/7 operation, the market's demands for underlying infrastructure have distilled into a few simple keywords: faster, more stable, cheaper, and more predictable. This is why 2026 will be a key year for Ethereum and Solana to confront each other directly— the former needs to prove it is not just "the safest asset layer," but can also handle high-frequency, large-scale on-chain financial activities; the latter needs to prove it is not just a high-performance testing ground or "meme land," but can support a global-level financial circulation foundation.

I. Upgrade Background of the Two Major Public Chains in 2026

1. Ethereum Upgrade Background: Moving from "the Safest Settlement Layer" to "High-Performance Financial Foundation"

Ethereum completed two mainnet upgrades in 2025: Pectra launched in May, and Fusaka went live in December, with the official designation of 2025 as the year with the richest output for the protocol layer. More importantly, these two upgrades are not just about stacking functions, but have gradually formed a clearer rhythm in the upgrade process: more frequent forks, smaller incremental deliveries, and continuous progress around scalability, account abstraction, and data availability. In other words, Ethereum is no longer satisfied with "outsourcing complex demands to L2," but is attempting to make L1 itself more resilient. By 2026, the Glamsterdam in the first half of the year and the subsequent Hegotá will be like two consecutive "system-level surgeries": the former focuses on L1 expansion capabilities and block production mechanism optimization, while the latter continues to push for more radical underlying transformations.
The goal of Glamsterdam is to separate the pressure of "block packaging" and "block execution," allowing validators to outsource block construction more safely and paving the way for parallel execution and higher gas limits. By the time of Hegotá, the keywords discussed within the developer community have further extended to deeper topics such as shorter slots, censorship resistance, native account abstraction, and post-quantum security. This can be simply understood as: Ethereum is upgrading from an "extremely robust but somewhat clunky" global settlement host to a still conservative, but significantly more capable financial operating system. It is like a heavy truck that used to prioritize not tipping over; in 2026, it needs to prove that it can not only avoid tipping over but also run faster under full load.

2. Solana Upgrade Background: Transitioning from "the Fastest Transaction Chain" to "Global Financial Settlement Layer"

On the other hand, Solana's story is completely different. In 2024, it regained market attention with the memecoin frenzy and explosive growth of pump.fun; entering 2025, the ecological heat experienced a decline, and on-chain activity and prices also faced significant fluctuations, but the truly noteworthy change was not in the price line, but in the infrastructure layer: Solana achieved its first full year of operation without downtime and maintained a stable slot time of about 400 milliseconds during the Agave 3.0 advancement; by the end of 2025, Firedancer had covered about 22% of total staking, significantly reducing the risk of a single client. The significance of this change is substantial—because Solana was most often criticized in the past not for insufficient speed, but for "being fast but prone to issues when congested." The performance in 2025 has led the market to seriously consider that it may indeed have the opportunity to transition from a high-performance public chain to a high-reliability financial infrastructure.
The upgrades in Solana in 2025 are essentially a pressure test before the major overhaul in 2026. Anza officially proposed Alpenglow in 2025, even directly calling it "the biggest change in Solana's core protocol history"; this new consensus design aims for lower latency, stronger security, and higher efficiency. One of Alpenglow's goals is to push the network's median finality below 150 milliseconds. Meanwhile, Firedancer is not just a "second client"; it represents Solana's ambition to break free from single implementation dependence and elevate both network performance and client diversity. Coupled with continuous optimization of Agave, increased computational units, network layer improvements, and a market microstructure roadmap, Solana has increasingly defined itself as the infrastructure for the internet financial market in the second half of 2025, rather than just a high-throughput platform suitable for issuing tokens, trading, and conducting on-chain experiments.
Thus, the real highlight of 2026 is not whether "Ethereum will become more like Solana," nor whether "Solana will completely replace Ethereum," but rather that the two routes are rarely converging towards the same direction. Ethereum aims to address performance, execution efficiency, and user experience shortcomings to be worthy of the next stage of on-chain financial scale; Solana is working on stability, client decentralization, and institutional-level credibility, attempting to convince the market that it is suitable not only for traffic surges but also for asset accumulation. Both paths ultimately point to the same question: what should the foundation for future internet finance look like— a cautiously evolving global clearing machine, or a real-time financial engine born for speed that compensates for reliability?

II. Ethereum's Mainline Task for the 2026 Upgrade: Reshaping L1 Capability Boundaries

In recent years, Ethereum's division of labor logic has been very clear: L1 is responsible for security, settlement, and decentralization, while L2 is responsible for scalability, low fees, and high-frequency interactions. However, as on-chain begins to bear more stablecoin settlements, RWA, transaction matching, and cross-chain settlement demands, L1 is not just a settlement center; it must also become a sufficiently fast, smooth, and predictable financial thoroughfare. This is why the Ethereum upgrade in 2026 feels no longer just about "fixing roads for L2," but rather about directly reshaping L1's own capability boundaries. In the protocol priority update released by the Ethereum Foundation in February 2026, the upcoming mainline is summarized as: parallel execution, higher gas limits, protocol-built PBS, continuous expansion of blobs, and progress in censorship resistance, native account abstraction, and post-quantum security. Glamsterdam is explicitly positioned as the next major network upgrade in the first half of 2026, while Hegotá is planned to follow in the second half.

1. Glamsterdam: Making the Mainnet No Longer "Half a Beat Slow"

The key to Glamsterdam is not just speed, but its attempt to solve two fundamental problems that Ethereum L1 has faced for a long time: first, the mainnet's throughput and capacity for complex transactions are not strong enough, and second, the block production and transaction ordering mechanisms still face significant MEV and centralization pressures.

• Higher gas limit: Between the two upgrades in 2025, the Ethereum community has gradually raised the mainnet gas limit from 30 million to 60 million, marking the most significant increase since 2021. Glamsterdam's direction is to continue pushing upwards from the existing 60M, potentially becoming a "ten-thousand TPS public chain."
• Achieving parallel execution: What truly gives Glamsterdam weight is its binding with parallel execution. The goal of parallel execution is to allow non-conflicting transactions to be processed more efficiently at the same time, thereby extracting higher actual throughput from the same "block space." For end users, this is likely to manifest as: transaction fees not suddenly skyrocketing during congestion, complex interactions being more smoothly packaged, and on-chain application experiences encountering fewer stalls and waits.

2. ePBS: Institutionalizing Transaction Ordering

Another truly "structural transformation" of Glamsterdam is the enshrined proposer-builder separation, abbreviated as ePBS or enshrined PBS. This is not a simple efficiency optimization but a fundamental reorganization of the block production process. To put it simply, the previous system was more like "the same person is responsible for taking orders, queuing, packaging, and finally serving the dishes"; what ePBS aims to do is break this process into clearer divisions of labor: proposers are responsible for block rights and consensus layer responsibilities, while builders are responsible for more efficiently organizing transactions and constructing execution loads.
This does not mean that "MEV will be eliminated." The significance of ePBS lies in attempting to move this matter from being primarily "gray, temporary, off-chain negotiation" to a stage that is "more open, more stable, and protocol-perceptible." This is especially crucial for institutions and large applications—because what they truly fear is not the existence of arbitrage in the market, but rather ambiguous transaction ordering rules, poor execution predictability, and strong implicit centralization risks in extreme cases.

3. Hegotá: Making Ethereum Lighter and More Usable

If Glamsterdam's keywords are "speeding up" and "restructuring," then Hegotá is more like Ethereum's "lightweight and usability engineering" for the second half of the year, with the main upgrade direction being: state slimming, censorship resistance, native account abstraction, and long-term node sustainability transformation. The two most important keywords are: statelessness and account abstraction.

• Statelessness: The goal is to verify new blocks without storing large amounts of historical and state data, thereby significantly reducing the cost of running nodes and making it easier for the entire network to maintain decentralization—because the lighter the nodes and the lower the hardware threshold, the less likely it is to evolve into a pattern where only a few large infrastructure service providers can reliably run full nodes. Additionally, Verkle is an important technical path for achieving state proof compression and promoting lightweight nodes, and in the long run, it is widely regarded as a key piece of the puzzle for Ethereum's state slimming.
• Account abstraction: The goal is to natively support smart contract wallets without relying on complex intermediate layers. In a more mature account abstraction system, wallets will no longer just be "safes for storing mnemonic phrases," but will increasingly resemble real internet financial accounts: they can set more flexible permissions, allow applications to pay gas fees, and support multi-signatures, social recovery, and batch operations, which will determine whether a large number of ordinary users and institutional users are willing to keep real funds on-chain for the long term.

Looking at Glamsterdam and Hegotá together, it becomes clear that Ethereum's true mainline in 2026 is not a single-point function, but a noticeable strategic shift: L1 is no longer just a "secure foundation," but is extending towards stronger execution, lower coordination costs, and better account experiences while maintaining its security foundation. Currently, Ethereum's gas prices are at extremely low levels: Etherscan's snapshot on March 19 showed low-end gas as low as 0.1 gwei, with multiple points fluctuating around 0.1 to 0.3 gwei. This indicates that after Dencun, Pectra, Fusaka, and L2 absorbing traffic, Ethereum's mainnet is no longer in the past "normal high fee" environment.

However, "cheap" itself is not the end goal. What truly matters is that after gas has significantly decreased, the capacity limits of L1 continue to be pushed forward. This means that Ethereum's competitiveness in the future will not only be about being "the safest," but will increasingly reflect that: while maintaining security and decentralization, the mainnet itself can also bear more real financial activities, rather than always leaving performance issues to be handled by peripheral expansion layers.

III. Solana's Mainline Task for the 2026 Upgrade: A Gamble from "Fast Chain" to "Global Settlement Layer"

Solana once fell into a low point due to the FTX collapse and multiple downtimes in 2022, being viewed by the market as a high-performance but unreliable representative. However, in 2024, applications like pump.fun lowered the barriers for issuing tokens and trading, driving a rapid explosion in Solana's on-chain activity. Although the price of SOL significantly retreated from historical highs between 2025 and 2026, Solana's infrastructure performance has actually become stronger. Solana aims to carry not just memes, bots, and retail high-frequency trading, but to further enter more serious financial scenarios such as payments, settlements, asset issuance, and on-chain capital markets.

1. Alpenglow: A Major Change in Consensus Mechanism

Alpenglow is the most core protocol-level upgrade for Solana in 2026. Anza officially calls it the biggest change in Solana's core protocol history, aiming to compress the network's finality to an approximate median of 150ms, ideally approaching 100ms. Its significance is mainly reflected in three points:

• Rewriting Consensus Logic: Replacing key parts of the original TowerBFT/PoH combination with a new mechanism to reduce confirmation latency.
• Enhancing Reliability: Simplifying consensus and clarifying verification and propagation paths to pave the way for higher throughput.
• Creating a Real-Time Financial Network: If finality can indeed be compressed to 100-150ms, Solana's transaction confirmation experience will be closer to that of real-time internet systems, rather than just traditional blockchain.

2. Firedancer: Client Diversity

If Alpenglow addresses how the consensus layer can confirm faster, then Firedancer addresses the reconstruction of client diversity. Solana officially stated at Breakpoint 2025 that after the mainnet launch of Firedancer, Solana will officially bid farewell to the "single-client network" phase and enter a true era of client diversity. This means that in the future, even if a certain client encounters a bug, it will not expose the entire network to the same risk. Currently, the Firedancer route has entered the mainnet practical phase, with Frankendancer already handling actual traffic on the mainnet, while the complete Firedancer is still being gradually pushed. The most important significance of Firedancer has three points:

• Reducing Single Client Risk: In the past, Solana's network relied heavily on Agave's client, with software implementation being too centralized, easily forming systemic vulnerabilities. The emergence of Firedancer essentially adds a "second engine" to Solana.
• Enhancing Network Resilience: With multiple clients coexisting, a single type of bug will no longer necessarily spread into a network-wide failure, which is crucial for high-frequency financial chains.
• Increasing Institutional Credibility: For scenarios involving payments, stablecoins, RWA, matching, and clearing, what truly matters is not the peak TPS in the lab, but rather that "the system does not fail together due to a fault in the same software stack." Firedancer brings Solana closer to an infrastructure that can be trusted by serious financial flows.

In summary, Alpenglow determines how fast Solana can be, while Firedancer determines whether Solana can sustain that speed in the long run. Only when both are established can Solana qualify to transition from "the fastest chain" to "a candidate for the global financial settlement layer."

IV. Comparison and Analysis of Ethereum vs. Solana Routes

Ethereum and Solana represent two completely different underlying philosophies: the former attempts to govern security, scalability, and user experience through modular layering; the latter hopes to complete execution, transactions, and settlements as much as possible within a single chain with high performance. They are not different solutions to the same problem but rather are answering two different questions: should internet finance resemble a global settlement network or a real-time financial operating system?

1. Route Divergence: Modular Financial Network vs. Monolithic Real-Time System

Ethereum's logic has always leaned towards "institutionalism." It believes that the most important thing at the underlying level is not extreme speed, but trustworthiness, stability, verifiability, and composability. Therefore, it defines L1 as a global settlement layer and security anchor, while delegating most high-frequency activities to L2. According to DefiLlama data, on March 19, 2026, Ethereum's main chain DeFi TVL was approximately $56.17 billion, with stablecoin size around $164.78 billion; meanwhile, L2BEAT statistics show that the total value collateralized on Ethereum's second layer is about $32.53 billion, with Arbitrum One at approximately $16.32 billion and Base at about $11.03 billion. This indicates that Ethereum is no longer a single-chain competition but a multi-layer financial network centered around the mainnet and extended by L2.

Solana represents another approach: to avoid fragmenting transactions, settlements, and liquidity across multiple layers, but rather to directly enhance performance, speed up confirmations, and lower costs on a single chain. As of March 19, 2026, Solana's on-chain DeFi TVL was approximately $6.92 billion, with stablecoin size around $15.13 billion, significantly lower than Ethereum; however, its 24-hour DEX trading volume reached $3.89 billion, far exceeding Ethereum's main chain's approximately $1.37 billion during the same period. This means that Solana's advantage lies not in asset accumulation depth but in trading activity and single-layer circulation efficiency.

Source: https://defillama.com/chain/Solana
In other words, Ethereum is more like "the underlying legal and clearing architecture of the global financial network," while Solana is more like "the real-time execution engine for high-frequency financial activities." Neither is inherently superior or inferior; rather, they serve different focal points.

2. Who is More Suitable for Institutional Funds and RWA?

Institutions care not only about transaction fees but also about the stability of rules, the sense of security for funds, the depth of asset accumulation, and compatibility with custody, auditing, compliance, and clearing infrastructures. Ethereum's main chain currently still possesses the deepest stablecoin pool in the industry, the most complete DeFi protocol layer, and the most mature institutional collaboration environment; in terms of stablecoin size, the stock of stablecoins on Ethereum exceeds $164 billion, which is more than ten times that of Solana. More importantly, Ethereum's upgrade direction in 2026 essentially addresses the weaknesses that Solana has been most likely to attack in the past: L1 is no longer satisfied with just being "the safest," but is advancing through parallel execution, higher gas limits, ePBS, and continuous account abstraction to ensure that the mainnet also possesses stronger actual financial carrying capacity.
However, from the perspective of "transaction efficiency" and "payment-style settlement," Solana's appeal will rise rapidly. In 2025, Solana completed its first full year of operation without downtime, maintaining a stable slot time of about 400 milliseconds, and by the end of the year, the Firedancer route client covered about 22% of total staking. This indicates that Solana is transitioning from "high performance but fragile" to "high performance and gradually reliable," which is precisely the premise that payment, settlement, market making, and high-frequency asset issuance scenarios care most about.
Therefore, in the context of institutions and RWA, a more accurate judgment is not "who wins or loses," but rather: Ethereum is more like an asset accumulation layer, while Solana is more like an asset circulation layer. The former is suitable for large assets to stay long-term, while the latter is more suitable for efficient movement of high-frequency funds.

3. Who is More Suitable for Ordinary Users and Consumer-Level Applications?

From the perspective of ordinary users, the answer will clearly lean towards Solana. Most users care about three questions: is the transfer fast, are the fees high, and is the operation complicated? In these dimensions, Solana's product experience is naturally closer to Web2—transactions are completed within a single chain, confirmation speeds are extremely fast, and costs are almost negligible, making user perception very direct. Solana remains highly attractive in consumer-level transactions, meme traffic, and bot-driven activities.
Ethereum's issue lies precisely in being "too mature and too complex." The main chain, L2, cross-chain bridges, different Rollups, different gas tokens, and different wallet abstraction paths, while each has its rationality from a system design perspective, often lead to an overly fragmented experience for ordinary users. The account abstraction and L1 performance upgrades in 2026 are indeed improving these issues, but at least for now, Solana still resembles a consumer-level financial product that can be used immediately, while Ethereum resembles a powerful financial operating system with a higher entry threshold.
Thus, if the goal is to first attract mass internet users, Solana clearly has a natural advantage; if the goal is to first serve high-value funds and complex financial protocols, Ethereum still has more institutional depth.
In summary, Ethereum's strength lies in "retaining funds." The main chain's stablecoin size, DeFi TVL, total value collateralized in L2, and historical institutional credibility constitute its deepest moat today. Solana's strength lies in "running traffic." High DEX transaction volumes, near real-time confirmations, low fees, and increasing client diversity make it more like the next-generation on-chain trading and payment network. The former represents financial credibility, while the latter represents financial efficiency.

V. Outlook and Conclusion

The competition between Ethereum and Solana essentially approaches the same goal: to become the most core and irreplaceable layer in the future on-chain financial world.
Ethereum has chosen a more robust and institutionalized path. It still insists that security, decentralization, and trustworthy settlement are the most important aspects of the underlying network, but the changes in 2026 indicate that it is no longer satisfied with just being "the safest settlement layer." Whether it is the advancement of Glamsterdam in parallel execution, higher gas limits, and ePBS, or the subsequent lightweight, account abstraction, and long-term state optimization direction represented by Hegotá, all indicate that Ethereum is striving to prove one thing: the most stable system can also become more efficient; the heaviest foundation can continue to evolve into a stronger financial thoroughfare.
Solana bets on single-chain high performance, near real-time confirmation, and extremely low interaction costs, believing that large-scale on-chain finance in the future does not necessarily have to rely on complex multi-layer divisions, but can also be directly supported by a sufficiently fast, smooth, and stable main chain. The rewriting of consensus in Alpenglow and the enhancement of client diversity in Firedancer both point to the same goal: the fastest system must not only be fast but also prove itself to be stable and reliable enough to support truly serious global financial activities.
Looking ahead, the next round of key variables that will determine the landscape may no longer be simply about bull-bear switches, but rather several more specific migrations: whether stablecoins continue to expand as a global payment and settlement network, whether RWA truly forms a large-scale on-chain asset pool, whether on-chain capital markets can accommodate more complex, higher-frequency, and more institutionalized trading demands, and whether ordinary users are willing to truly stay long-term at the wallet, payment, and application layers.
In conclusion, 2026 is not the final battle but more like an open qualification round: Ethereum is striving to prove that the most stable system can also be fast enough; Solana is working to prove that the fastest system can also be stable enough. Both are crossing their most obvious boundaries from the past and approaching a higher level of competition. The real answer will be written in the actual direction of the next round of stablecoins, RWA, and global on-chain capital market migrations.
