How Ethereum Plans to Scale to 10,000 TPS with ZK Technology by 2026
Ethereum plans to use a new method called zero-knowledge proofs to speed up its network, aiming to handle 10,000 transactions per second by 2026. This change is designed to make the system faster while keeping it secure and decentralized.
What happened
Ethereum has set a target of reaching approximately 10,000 transactions per second (TPS) by the year 2026 through the adoption of zero-knowledge (ZK) proof technology. This ambition is part of a broader scaling roadmap publicly outlined by the Ethereum Foundation and supported by industry participants such as ConsenSys.
Central to this scaling strategy is the deployment of ZK-rollups, a technology that aggregates multiple transactions off-chain into a single proof. This proof is then submitted to the Ethereum mainnet, where it is efficiently verified, significantly reducing the computational load and data footprint on-chain. According to the Ethereum Foundation, this compression of transaction data and succinct proof generation enables the mainnet to validate thousands of transactions with minimal on-chain resource consumption.
Zero-knowledge proofs, by design, allow the network to verify the correctness of large batches of transactions without revealing sensitive information, thereby preserving or potentially enhancing network security. Vitalik Buterin and other Ethereum developers have emphasized that this cryptographic approach maintains the integrity of the network while scaling throughput.
Decentralization considerations are explicitly addressed in Ethereum’s plans. The infrastructure responsible for generating ZK proofs—the prover nodes—is intended to remain permissionless and open. This design seeks to avoid centralization risks often associated with off-chain computation, ensuring that no single entity controls the proof generation process.
Analysts and blockchain researchers interpret the integration of ZK technology as a paradigm shift in scalability. Unlike traditional Layer 1 scaling or sharding, ZK-rollups leverage cryptographic proofs to compress and validate transactions more efficiently. This approach is expected to enable Ethereum to compete more effectively with centralized payment networks, supporting more complex decentralized applications (dApps) and expanding decentralized finance (DeFi) use cases.
Why this matters
Scaling blockchain networks without compromising security or decentralization has long been a core challenge in the industry. Ethereum’s plan to reach 10,000 TPS using ZK-rollups represents a significant evolution in addressing this problem.
Achieving such throughput would mark a substantial improvement over current Ethereum mainnet capacities, which typically handle tens of transactions per second. By enabling thousands of transactions to be processed securely and efficiently, Ethereum could support a wider range of applications, including high-frequency trading, gaming, and large-scale DeFi protocols, potentially broadening user adoption and utility.
From a market perspective, this scaling could position Ethereum more competitively against centralized payment systems, which offer high transaction speeds but lack the decentralization and censorship resistance inherent to blockchain networks. The use of zero-knowledge proofs also aligns with broader trends in privacy and cryptographic security innovations within the blockchain ecosystem.
Moreover, Ethereum’s explicit commitment to maintaining permissionless prover infrastructure addresses ongoing concerns about centralization risks in Layer 2 scaling solutions. This focus on decentralization is critical for sustaining trust in the network and supporting its role as a foundational platform for decentralized applications.
What remains unclear
Despite the outlined roadmap and technological direction, several important details remain unspecified or unresolved in public communications.
First, the precise timeline and specific milestones for deploying ZK-rollup infrastructure capable of consistently handling 10,000 TPS are not detailed beyond the general 2026 target. This leaves uncertainty about the stages of development, testing, and incremental capacity increases leading up to full-scale deployment.
Second, the long-term implications for decentralization are not fully clarified. While the intention to keep prover infrastructure permissionless is stated, the governance mechanisms, incentive models, and distribution of prover nodes and data availability committees remain under development. This raises questions about how decentralization will be maintained as throughput scales and network complexity increases.
Third, interoperability between ZK-rollups and other Layer 2 solutions, such as optimistic rollups and sharding, has not been comprehensively addressed. The absence of a unified roadmap integrating these scaling methods leaves open questions about user experience coherence and cross-solution compatibility.
Finally, technical trade-offs inherent in achieving very high TPS levels remain a subject of ongoing research. These include balancing data compression, proof size, and verification time. No publicly available benchmarking data confirms that Ethereum’s mainnet can sustain 10,000 TPS using ZK-rollups in practice as of now.
Additional uncertainties include the economic models for prover incentives, the impact of zero-knowledge proofs on user privacy beyond transaction compression, and the potential security risks introduced by new cryptographic primitives or implementation complexities—none of which have been fully assessed in public audits or formal verification reports.

Ethereum’s ambition to scale to 10,000 TPS by 2026 using zero-knowledge proofs represents a significant technological advancement with broad implications for blockchain scalability, security, and decentralization. While the foundational concepts and strategic direction are clear, critical details about implementation, governance, interoperability, and security remain to be disclosed or finalized. These open questions will be pivotal in determining how effectively Ethereum can deliver on its scaling promises and maintain its position as a leading decentralized platform.
