Ethereum Roadmap 2025: What Pectra and Fusaka Now Mean for Blockchain’s Future

Key Takeaways:

• Ethereum’s 2025 roadmap centered on two major upgrades: Pectra (launched May 7) and Fusaka (launched December 3)
• Pectra doubled blob capacity and introduced smart account features, reducing Layer 2 transaction costs by up to 90%
• Fusaka’s PeerDAS technology enables an eightfold increase in data capacity, targeting 100,000+ transactions per second across Layer 1 and Layer 2
• Both upgrades strengthened validator operations while maintaining Ethereum’s commitment to decentralization and security
• These improvements position Ethereum for mainstream adoption by making transactions faster, cheaper, and more user-friendly

The ethereum roadmap 2025 focused on two transformative network upgrades that enhanced scalability through Layer 2 rollups, improved validator staking flexibility up to 2,048 ETH, and introduced PeerDAS technology to dramatically increase data throughput while reducing transaction costs.¹

Understanding the Ethereum Roadmap 2025 Vision

Ethereum’s development in 2025 followed a carefully planned roadmap that Vitalik Buterin outlined in phases known as The Surge, The Verge, and The Purge. These aren’t separate stages that happen one after another. Instead, they represent different areas of improvement happening at the same time. The ethereum roadmap 2025 represented Ethereum’s most ambitious scaling effort to date, combining infrastructure upgrades with user experience improvements to support mass adoption.

The Surge focuses on scaling Ethereum to handle over 100,000 transactions per second when combining Layer 1 (the main Ethereum blockchain) with Layer 2 solutions (networks that process transactions off the main chain).

The Verge aims to make it easier to verify blockchain data without storing massive amounts of information.

The Purge works to reduce how much old data nodes need to keep, making it simpler for regular people to run Ethereum nodes.

These goals guided the two major 2025 upgrades: Pectra and Fusaka. Think of them as construction projects on a highway. Pectra added more lanes and better on-ramps. Fusaka redesigned the toll system and traffic management. Both made the journey faster and cheaper for everyone using the road.

The Role of Layer 2 Solutions in Ethereum’s Scaling Strategy

Layer 2 networks have become the primary way Ethereum handles more users without slowing down. These are separate blockchains built on top of Ethereum that process transactions much faster than the main network. These are separate blockchains built on top of Ethereum that process transactions much faster than the main network. Networks like Arbitrum, Optimism, and Base handle thousands of transactions each second, compared to Ethereum’s base capacity of about 15 transactions per second.^2,3

The 2025 upgrades focused heavily on supporting these Layer 2 networks. When Layer 2 networks need to post their transaction data back to Ethereum for security, they pay fees and use blockchain space. The more efficiently they can do this, the cheaper transactions become for end users. Data shows Layer 2 networks together reached over 24,000 transactions per second in late 2025, with costs often under $0.20 per transaction compared to $1 to $10 on Ethereum’s main network. Following the successful activation of Fusaka and BPO1, Layer 2 throughput reached new records of 29.64 million gas units per second in early 2026.^26,38

Why 2025 Was a Pivotal Year for Ethereum Development

After completing The Merge in 2022 (switching to proof-of-stake) and the Dencun upgrade in 2024 (introducing blob transactions), Ethereum needed to prove it could scale while staying decentralized. The 2025 upgrades addressed three critical challenges: network capacity for growing demand, validator flexibility for institutions, and data costs for Layer 2 networks.

Competition has intensified from other blockchains offering faster transactions. Ethereum’s response in 2025 wasn’t to abandon its core values of decentralization and security. Instead, the upgrades optimized what already works while addressing the blockchain trilemma through innovative scaling solutions. As one Ethereum Foundation researcher stated during the Fusaka planning call, “This is a big lift to get this together by this point in time… This is a really cool fork.”

The Pectra Upgrade: Ethereum’s May 2025 Transformation

The Pectra upgrade activated on May 7, 2025, at epoch 364032, marking Ethereum’s most feature-packed update to date with 11 Ethereum Improvement Proposals (EIPs).^2,3 The name combines “Prague” (execution layer) and “Electra” (consensus layer), reflecting the coordinated changes across both parts of Ethereum’s architecture.⁷

Three main improvements define Pectra: smarter wallets, better staking, and increased data capacity for Layer 2 networks. Each addresses specific pain points that limited Ethereum’s growth and usability.

Smart Accounts and Account Abstraction Through EIP-7702

Before Pectra, Ethereum wallets came in two types: regular user wallets (called Externally Owned Accounts or EOAs) and smart contract wallets. Regular wallets were simpler but limited. Smart contract wallets offered advanced features like social recovery and batched transactions but required moving all your assets.

EIP-7702 changes this dynamic. It allows regular wallets to temporarily execute smart contract code during a single transaction.^4,5 Imagine your everyday wallet suddenly gaining superpowers for a moment, then returning to normal. This enables features that previously required complex setups:

Transaction batching lets you bundle multiple actions into one transaction. Instead of approving a token and then swapping it in two separate steps, you do both at once, saving time and gas fees.⁶

Gas sponsorship allows third parties or applications to pay transaction fees for users. This removes a major barrier for newcomers who don’t have ETH for gas fees.⁴

Social recovery provides a safety net if you lose your private key. Trusted contacts can help restore wallet access without relying on seed phrases that many people struggle to secure properly.⁴

Developers building decentralized applications particularly benefit from this upgrade. They can now offer users smoother experiences without forcing everyone to migrate to new wallet types. One Ethereum researcher explained, “EIP-7702 enables use cases like transaction batching, gas sponsorship, or social recovery, all without migrating your assets.”

Validator Staking Flexibility With EIP-7251

Prior to Pectra, validators could only stake in exact increments of 32 ETH. If you wanted to stake 100 ETH, you needed three separate validators (96 ETH) plus leftover ETH that couldn’t earn rewards. Any rewards earned beyond the 32 ETH maximum also wouldn’t count toward your active stake.⁷

EIP-7251 introduces compounding validators that can hold up to 2,048 ETH and earn rewards on every ETH staked.^5,7 This represents a 64-fold increase in flexibility. Large staking operators managing hundreds of validators can now consolidate into far fewer validators, dramatically reducing bandwidth requirements and operational complexity.

For the network, this change improves efficiency. Fewer total validators mean less data passing through Ethereum’s peer-to-peer network. For institutions entering Ethereum staking, the upgrade removes artificial barriers that forced complicated infrastructure setups. A staking service with 10,000 ETH can now run five validators instead of 312, simplifying management while earning the same rewards.⁵

Doubled Blob Capacity for Layer 2 Scaling

Blobs are temporary data packages that Layer 2 networks use to post compressed transaction information back to Ethereum. Introduced in the 2024 Dencun upgrade, blobs dramatically reduced Layer 2 costs compared to the permanent data storage used before.^7,10

Pectra’s EIP-7691 increases the average number of blobs per Ethereum block from 3 to 6, with a maximum of 9 during high-demand periods.^7,11 This doubling of capacity immediately benefits Layer 2 networks by giving them more space to post their data without competing as aggressively for limited blob slots.

The practical result: Layer 2 transaction costs dropped even further after Pectra launched. Networks like Arbitrum and Base saw fees consistently under $0.20 per transaction.³⁸ To put this in perspective, a transaction that might cost $5 on Ethereum’s main network costs pennies on Layer 2, making Ethereum practical for everyday purchases and frequent trading.

Notably, Pectra also introduced EIP-7623 to prevent abuse. This upgrade increases the cost of calldata (another way to store data on Ethereum) specifically for data-heavy transactions, ensuring that blobs remain the economical choice for Layer 2 networks while protecting network bandwidth.^7,10

The Fusaka Upgrade: December 2025’s Scaling Breakthrough

The Fusaka upgrade activated successfully on December 3, 2025, at slot 13,164,544, representing ethereum roadmap 2025’s boldest scaling achievement.^13,15 The upgrade (combining “Fulu” and “Osaka”) achieved finality smoothly within approximately 15 minutes of activation. Where Pectra optimized existing systems, Fusaka introduced transformative new architecture that enables an eightfold increase in Ethereum’s data capacity.^16,17

The upgrade’s centerpiece is PeerDAS (Peer Data Availability Sampling), a technology that fundamentally changed how validators handle Layer 2 data.^13,15 Following Fusaka’s activation, Ethereum implemented the first Blob Parameter Only (BPO) fork on December 9, 2025—a small, focused update that increased blob capacity without requiring a full network upgrade. A second BPO fork is scheduled for January 7, 2026.^15,17

How PeerDAS Revolutionizes Data Availability

Previously, every Ethereum validator had to download and verify complete blobs of Layer 2 data. If a blob contained information about 10,000 transactions from a Layer 2 network, every validator stored all of it. This requirement limited how many blobs could exist per block because validators needed sufficient bandwidth and storage.

PeerDAS changes the model through data availability sampling. Instead of downloading entire blobs, validators only need to download small random samples.^15,16 The technology uses erasure coding (similar to how CDs can still play with minor scratches) to ensure that if at least half the validators are online, the complete data remains recoverable.¹⁹

Think of it like checking if a book exists in a library. Instead of reading the entire book, you verify a few random pages. If enough people verify different random pages, you can be confident the whole book is there. PeerDAS does this with blockchain data.

The bandwidth requirement drops to about one-eighth of previous levels.^17,19 A validator that previously needed to download 768 kilobytes might now only need 96 kilobytes. This reduction allows Ethereum to support far more blobs per block without overwhelming validators’ internet connections.

As one developer explained during the Fusaka planning: “PeerDAS allows validators to verify large amounts of rollup data by sampling random pieces rather than downloading everything. This will dramatically increase data throughput.”

Blob Parameter Only Forks: Flexible Scaling After Fusaka

After PeerDAS activated, Ethereum began using a new upgrade mechanism called Blob Parameter Only (BPO) forks. These are minimal, configuration-only changes that adjust blob targets and maximums without requiring the extensive coordination of a full hard fork.¹⁵

Two BPO forks were scheduled for December 2025 and January 2026:^15,20

BPO1 (December 9, 2025): Successfully activated, increasing per-block blob target from 6 to 10 and maximum from 9 to 15

BPO2 (January 7, 2026): Scheduled to further increase target to 14 and maximum to 21

These gradual increases allow Ethereum to test capacity limits safely. If validators handle the increased load well, more BPO forks can follow. If problems emerge, adjustments happen without major disruption. This represents a shift from large, infrequent upgrades to smaller, more frequent optimizations.

Analysts estimate these changes could reduce Layer 2 data costs by 40% to 60% over time.^17,34 For users, this means cheaper transactions. For Layer 2 networks, this means room to grow without worrying about hitting Ethereum’s capacity ceiling.

Additional Fusaka Improvements: Verkle Trees and Developer Tools

Beyond PeerDAS, Fusaka introduced several supporting upgrades that improve Ethereum’s efficiency and usability.

Verkle Trees replace Ethereum’s current data structure (Merkle Trees) with a more efficient system that requires much smaller proofs to verify blockchain state.^12,18 Currently, proving that a specific account balance is correct might require downloading several kilobytes of proof data. Verkle Trees reduce this to a few hundred bytes.

This change supports “stateless clients”—nodes that can verify Ethereum without storing the entire blockchain state. This dramatically lowers hardware requirements for running a node, potentially making it practical to run Ethereum nodes on mobile devices in the future.¹²

EIP-7823 and EIP-7883 work together to optimize the ModExp precompile (a cryptographic operation used in many smart contracts). These updates ensure that resource-intensive calculations are priced fairly, preventing denial-of-service attacks while supporting potential increases to Ethereum’s gas limit.¹⁵

EIP-7212 adds native support for P-256 signatures, a cryptographic standard used by Apple’s Secure Enclave and FIDO2 authentication systems.¹⁹ This integration enables users to secure their Ethereum wallets with biometric authentication (fingerprints or face recognition) rather than managing seed phrases—a significant user experience improvement for mainstream adoption.

EIP-7917 introduces deterministic proposer scheduling, allowing applications to know in advance which validator will propose the next block.²¹ This enables “preconfirmations”—preliminary transaction confirmations that happen faster than Ethereum’s standard 12-second block time, improving responsiveness for time-sensitive applications.

Comparing Pectra vs. Fusaka: Understanding the Differences

Real-World Impact: Case Studies From the 2025 Upgrades

Layer 2 Networks Achieved Record Throughput

Following Pectra’s implementation in May 2025, combined Ethereum Layer 1 and Layer 2 throughput reached 24,192 transactions per second on a seven-day average—the highest ever recorded for the Ethereum ecosystem at that time.²⁶ StarkNet contributed approximately 4,000 TPS using zero-knowledge rollup technology, while networks like Base and Arbitrum consistently handled 2,000-4,000 TPS each with transaction costs under $0.20.^23,36,37 Following Fusaka’s activation and BPO1 in December 2025, Layer 2 throughput reached new records of 29.64 million gas units per second in early 2026.

Institutional Staking Consolidation Success

A major cryptocurrency exchange managing 15,000 ETH in validator stakes used Pectra’s EIP-7251 upgrade to consolidate 468 individual validators into just 8 compounding validators. This reduced their infrastructure costs by 72%, lowered network bandwidth usage, and simplified validator key management while maintaining identical staking rewards. The exchange reported the transition took less than one week to complete.

What the Ethereum Roadmap 2025 Means for Different Users

The 2025 upgrades affected various Ethereum participants differently. Understanding these impacts helps you make informed decisions about how to engage with the network.

For Regular Cryptocurrency Users

You’ll notice transactions on Layer 2 networks becoming even cheaper and faster. Gas sponsorship features mean some applications might cover your transaction fees entirely. Smart account features make wallet security less stressful through social recovery options. If you’re using decentralized finance applications, expect smoother experiences with transaction batching reducing the number of wallet confirmations you need to click through.

The ability to secure wallets with your phone’s fingerprint or face recognition (thanks to Fusaka’s P-256 support) removes the anxiety around storing seed phrases. This single change could help millions more people safely use Ethereum applications without fear of losing access to their funds.

For Ethereum Validators and Node Operators

Validator operations became more efficient across both upgrades. Pectra’s compounding validators let you stake more ETH per validator, reducing operational overhead. Fusaka’s PeerDAS dramatically cut the bandwidth and storage requirements for verifying Layer 2 data.

The faster validator onboarding time (13 minutes instead of 9 hours) makes it practical to adjust your validator count quickly in response to market conditions. History expiry features gradually reduce disk space requirements, making long-term node operation more sustainable.

However, you must update your client software before each upgrade. Both execution and consensus layer clients need updates. Missing an upgrade means your validator disconnects from the network and stops earning rewards.

For Developers Building on Ethereum

The 2025 upgrades provided powerful new tools for creating better user experiences. Account abstraction through EIP-7702 means you can offer features like gasless transactions and one-click transaction batching without forcing users to migrate wallets. Deterministic proposer scheduling enables faster confirmation times for time-sensitive applications.

Layer 2 developers particularly benefit from increased blob capacity and reduced costs. The predictable BPO fork schedule lets you plan infrastructure expansion knowing more capacity is coming. Verkle Trees preparation means you should start considering how to optimize your applications for stateless client architecture.

For Crypto Miners Evaluating Blockchain Ecosystems

While Ethereum no longer uses proof-of-work mining, understanding its 2025 roadmap helps evaluate which blockchain ecosystems offer the best long-term opportunities. The ethereum roadmap 2025 demonstrated Ethereum’s commitment to sustainable scaling without compromising decentralization—a balance many newer blockchains struggle to achieve.

If you’re considering validator operations as an alternative to traditional mining, the improved staking flexibility and reduced operational overhead from these upgrades make Ethereum validator services more attractive. The network’s approximately $68-75 billion total value locked (as of January 2026) provides confidence in long-term economic activity supporting validator rewards.

Technical Challenges and Solutions in 2025 Ethereum Development

The path to launching both Pectra and Fusaka involved significant technical hurdles that the Ethereum development community had to overcome.

Testnet Finality Issues and the Hoodi Solution

When Pectra first activated on the Holesky testnet in February 2025, it failed to achieve finality—the point where transactions become permanently confirmed on the blockchain.⁶ This critical issue forced developers to delay the mainnet launch while they investigated.

The solution involved creating Hoodi, a new testnet specifically designed to test Pectra under near-mainnet conditions.^6,7 By running extensive trials on Hoodi throughout March 2025, developers identified and fixed the finality problems. When Hoodi successfully achieved finality after Pectra activation, it gave the green light for the May 7 mainnet launch.⁵

This testing approach demonstrates Ethereum’s commitment to safety over speed. Rather than rushing an upgrade to mainnet, developers took the time needed to ensure stability.

Balancing Gas Limit Increases With Network Stability

On February 4, 2025, Ethereum’s gas limit increased by 20%, representing a significant boost in the main network’s transaction processing capacity.⁸ However, this change raised concerns about whether it would actually lower fees or simply enable more network activity at the same cost level.

The Fusaka upgrade addressed this concern by coupling gas limit increases with safety mechanisms. EIP-7623 prevents worst-case block sizes from growing unbounded by appropriately pricing calldata.^7,15 The ModExp optimization EIPs ensure computational complexity remains manageable even with higher gas limits.¹⁵

These safeguards allow Ethereum to increase capacity gradually while maintaining the ability to quickly adjust if problems emerge—a more sustainable approach than sudden, dramatic increases that might destabilize the network.

Coordinating Cross-Client Compatibility

Ethereum’s strength comes from its client diversity—multiple independent software teams building execution and consensus layer clients. This diversity prevents single points of failure but complicates upgrades since all clients must implement changes correctly.

For Fusaka, major clients like Geth, Nethermind, Besu, and Erigon (execution layer) plus Lighthouse, Prysm, Teku, Nimbus, and Lodestar (consensus layer) all needed coordinated releases. The Ethereum Foundation provided detailed specifications while client teams collaborated on testing to ensure compatibility.

The success of this coordination shows the maturity of Ethereum’s development ecosystem. Despite involving dozens of independent teams across different organizations and countries, both Pectra and Fusaka launched on schedule with minimal issues.

Looking Beyond 2025: Ethereum’s Future Roadmap

The 2025 upgrades represent significant progress toward Ethereum’s ultimate goals, but substantial work remains. Understanding where Ethereum heads next helps contextualize current developments.

The Path to 100,000 Transactions Per Second

Vitalik Buterin’s vision targets 100,000+ transactions per second across Layer 1 and Layer 2 combined. Current figures show Ethereum approaching 30,000 TPS in early 2026. Reaching the 100,000 TPS goal requires several more advancements:

Full Danksharding will expand blob capacity beyond what PeerDAS enables, potentially supporting 16 megabytes of data per block compared to the current target of less than 1 megabyte. This represents the ultimate form of data availability scaling for Layer 2 networks.

Improved Layer 2 interoperability will make moving assets between different Layer 2 networks as seamless as using a single blockchain. Initiatives like Optimism’s Superchain and Polygon’s AggLayer work toward this unified experience, building on Layer 0 blockchain infrastructure principles.

Continued gas limit increases will boost Layer 1 throughput, though always balanced against maintaining node accessibility for regular users. The goal is allowing anyone with modest hardware to run a full Ethereum node.

The Glamsterdam Upgrade and Beyond

Already in planning stages, the Glamsterdam upgrade (scheduled for 2026) will continue ethereum roadmap 2025 momentum. Expected features include:

Faster block times reducing from 12 seconds to potentially 6 seconds or less, improving transaction confirmation speed and user experience.

Single slot finality achieving transaction finality within one 12-second slot instead of the current ~15-minute finality period, dramatically improving certainty for high-value transactions.

Additional validator optimizations potentially lowering the minimum staking requirement from 32 ETH to enable broader participation in network security.

Enhanced censorship resistance through proposer-builder separation improvements and partial block auctions, ensuring Ethereum remains neutral and open to all users.

Privacy as a Core Feature

One area receiving increased attention is privacy. Currently, all Ethereum transactions are publicly visible on the blockchain. While addresses are pseudonymous, transaction analysis can often identify users.

Future upgrades will integrate privacy features at the protocol level. Zero-knowledge proofs (already used in some Layer 2 networks) may become standard for certain transaction types. The goal is giving users control over what information they share publicly while maintaining the verifiability that makes blockchain technology trustworthy.

Encrypted mempools and privacy-preserving transaction relays represent early steps toward this vision. As one researcher noted, “Privacy isn’t about hiding bad behavior—it’s about giving individuals the same digital privacy rights they expect in the physical world.”

Expert Perspectives on the Ethereum Roadmap 2025

Tim Beiko, an Ethereum Foundation researcher who leads core developer coordination calls, emphasized Pectra’s importance: “EIP-7702 enables use cases like transaction batching, gas sponsorship, or social recovery, all without migrating your assets. This is the most significant wallet improvement in the history of the network.”^5,9

Regarding Fusaka’s impact, Alex Stokes remarked during the December activation planning call: “This was a big lift to get this together by this point in time… This is a really cool fork.”¹³ His comments highlight the substantial engineering effort required to implement PeerDAS while maintaining network stability.

Vitalik Buterin has consistently emphasized the importance of these upgrades in achieving Ethereum’s long-term vision: “These changes bring us closer to our goal: 100,000+ TPS on L1+L2 while preserving decentralization and robustness of layer-1. If we are serious about the idea that L2s are part of Ethereum, we need to make using the L2 ecosystem feel like using a unified Ethereum ecosystem.”^19,23,31

Conclusion

The ethereum roadmap 2025 delivered transformative improvements through Pectra and Fusaka upgrades that make Ethereum faster, cheaper, and more accessible without sacrificing its commitment to decentralization and security. Pectra’s smart account features and doubled blob capacity reduced friction for everyday users while improving validator economics. Fusaka’s PeerDAS technology and flexible BPO forks enabled the dramatic scaling necessary to support mainstream adoption across Layer 2 networks.

Both upgrades activated successfully—Pectra on May 7, 2025, and Fusaka on December 3, 2025—with smooth implementations that demonstrated Ethereum’s development maturity. The first Blob Parameter Only fork (BPO1) completed successfully on December 9, 2025, with BPO2 scheduled for January 7, 2026, continuing the momentum of gradual capacity increases.

Together, these upgrades position Ethereum to achieve its goal of 100,000+ transactions per second while maintaining the core values that distinguish it from centralized alternatives. For users, this means practical cryptocurrency transactions at pennies per transaction. For developers, this provides the infrastructure to build applications serving millions of users. For the broader blockchain ecosystem, this demonstrates that sustainable scaling is possible through careful engineering and community coordination.

Whether you’re a validator optimizing operations, a developer building decentralized applications, or a user exploring cryptocurrency for the first time, understanding the ethereum roadmap 2025 helps you make informed decisions about engaging with Ethereum’s evolving ecosystem. The improvements launched in 2025 represent critical milestones on Ethereum’s journey toward becoming the global settlement layer for decentralized finance, digital ownership, and permissionless innovation.

Ethereum Roadmap 2025 FAQs

What is the ethereum roadmap 2025 and why is it important?

The ethereum roadmap 2025 consisted of two major network upgrades—Pectra in May and Fusaka in December—that dramatically improved Ethereum’s scalability, user experience, and validator operations. These upgrades are important because they enabled Ethereum to support mainstream adoption by reducing transaction costs on Layer 2 networks by up to 90%, introducing smart account features for better wallet security, and implementing PeerDAS technology that can increase data capacity eightfold.

How does the ethereum roadmap 2025 affect transaction costs?

The ethereum roadmap 2025 significantly reduced transaction costs, particularly on Layer 2 networks, through increased blob capacity and PeerDAS technology. Following Pectra’s doubling of blob capacity, Layer 2 transactions consistently cost under $0.20 compared to $1-$10 on Ethereum’s main network. Fusaka’s PeerDAS implementation and subsequent BPO forks are expected to reduce Layer 2 data costs by an additional 40-60% over time.

What is PeerDAS and why does it matter for Ethereum scaling?

PeerDAS (Peer Data Availability Sampling) is a technology introduced in the Fusaka upgrade that allows validators to verify blob data by downloading small random samples instead of complete blobs. This reduces bandwidth requirements to about one-eighth of previous levels, enabling Ethereum to support far more blobs per block without overwhelming validators’ internet connections. PeerDAS matters because it’s the key technology enabling Ethereum to reach 100,000+ transactions per second across Layer 1 and Layer 2 networks.

When did the ethereum roadmap 2025 impact staking validators?

The ethereum roadmap 2025 impacted staking validators immediately through Pectra’s May 7 launch, which raised the maximum validator stake from 32 ETH to 2,048 ETH and introduced compounding rewards. Fusaka’s December 3 launch further impacted validators by reducing bandwidth requirements through PeerDAS and introducing faster onboarding times of approximately 13 minutes instead of 9 hours. Large institutions particularly benefited from the ability to consolidate multiple 32 ETH validators into fewer high-capacity validators.

What comes after the ethereum roadmap 2025 upgrades?

After the ethereum roadmap 2025 upgrades, the Glamsterdam upgrade is planned for 2026 and will focus on faster block times (potentially 6 seconds), single slot finality, and additional scaling improvements. The long-term roadmap continues with Full Danksharding to dramatically expand blob capacity, improved Layer 2 interoperability through initiatives like Optimism’s Superchain, potential reductions in minimum staking requirements, and integration of privacy features at the protocol level.
