Ethereum’s journey from a nascent smart contract platform to a global decentralized computing engine has been defined by one overarching goal: scalability. As transaction demand grows and user expectations rise, Ethereum is pushing toward an ambitious milestone — 100,000 transactions per second (TPS) across its ecosystem. This target isn’t just aspirational; it’s a core component of Ethereum’s long-term roadmap known as The Surge, designed to make the network capable of supporting mass adoption without sacrificing decentralization or security.
Today, Ethereum processes around 13 TPS on Layer 1 (L1), with Layer 2 (L2) rollups adding another ~296 TPS collectively. While this represents a 21x improvement over just a few years ago, it's still far from the scale needed to compete with centralized systems like Visa, which handles tens of thousands of transactions per second. Bridging that gap requires a multi-pronged technical evolution — one that combines data availability innovations, execution efficiency, and seamless user experience.
The Rise of Rollups and the Dencun Upgrade
The most visible leap in Ethereum’s scalability so far has come from the explosive growth of Layer 2 rollups. Today, there are over 105 active rollups — a number that was nearly unthinkable just a few years ago when high gas fees drove users toward alternative Layer 1 blockchains.
This shift was accelerated by the Dencun upgrade in March 2024, which introduced EIP-4844. This critical enhancement brought proto-danksharding to Ethereum, drastically reducing the cost for L2s to post transaction data on L1. By introducing blob transactions, the upgrade cut data posting costs by up to 90%, making rollups significantly more affordable and efficient.

The proliferation of Rollup-as-a-Service (RaaS) platforms like Caldera and Conduit has further democratized access to scalable infrastructure, enabling teams to deploy custom rollups in minutes rather than months. Combined with emerging data availability (DA) solutions such as Celestia, these tools are laying the foundation for a modular blockchain future — where computation, consensus, and data storage are decoupled for maximum efficiency.
The Path to 100K TPS: Key Technical Milestones
Reaching 100,000 TPS won’t happen overnight. It requires several interlocking upgrades across Ethereum’s stack:
1. PeerDAS: Decentralized Data Availability at Scale
One of the biggest bottlenecks in scaling Ethereum is data availability — ensuring that all participants can verify that transaction data is published and accessible. PeerDAS (Peer Data Availability Sampling) aims to solve this by borrowing concepts from peer-to-peer file-sharing networks like BitTorrent.
Under PeerDAS, validators sample small fragments of transaction data from different nodes instead of downloading entire datasets. This distributed approach reduces bandwidth pressure and allows the network to handle exponentially more data without requiring every node to store everything — a crucial step toward supporting thousands of high-throughput rollups.
2. Signature Aggregation with BLS Signatures
Every time you approve a token transfer in MetaMask, your wallet generates an ECDSA signature. Today, an ERC-20 transfer consumes about 180 bytes of data — largely due to signature overhead. By switching to BLS (Boneh-Lynn-Shacham) signatures, Ethereum can aggregate multiple signatures into a single compact proof.
This means hundreds of transactions could be verified with one cryptographic check, reducing signature data size to as little as 30 bytes per transaction. The result? Drastically lower data costs and higher throughput — especially vital for account abstraction and smart contract wallets that batch many operations.
3. Plasma and Validiums: Off-Chain Computation with On-Chain Trust
While rollups post full transaction data on-chain, plasma chains and validiums take a different approach: they publish only Merkle roots of blocks on Ethereum, keeping actual data off-chain. This model offers even greater scalability but traditionally sacrifices some data availability guarantees.
With improved fraud proof mechanisms and trusted setups being phased out via zero-knowledge proofs, plasma and validium architectures are regaining attention as potential high-efficiency solutions — particularly for use cases where data privacy or throughput is paramount.
4. L1 Execution Efficiency: Beyond Settlement
A major concern in Ethereum’s scaling journey is the risk of L1 becoming a “ghost chain” — used only for settlement and data availability while all meaningful activity shifts to L2s. To prevent this, Ethereum must remain capable of handling complex operations when necessary.
Upgrades like EVM Object Format (EOF) aim to make smart contract execution more efficient by standardizing bytecode behavior and enabling better optimization. Meanwhile, proposals for multidimensional gas pricing seek to create separate markets for computation, storage, and data — ensuring resources are priced fairly and preventing congestion from any single resource type.
Vitalik Buterin has emphasized that Ethereum must remain robust enough to manage “a highly complex and chaotic wind-down of an L2” if needed — underscoring the importance of long-term security and resilience at the base layer.

Improving User Experience: Chain Abstraction and Interoperability
Even with perfect scalability, Ethereum will struggle with mass adoption if users have to navigate dozens of fragmented chains with different bridges, tokens, and UX patterns.
Efforts in chain abstraction aim to hide this complexity entirely — letting users interact with apps seamlessly across L1 and L2s without managing gas, approvals, or bridging manually. Projects working on shared sequencers are also helping standardize ordering and finality across multiple rollups, reducing fragmentation.
At the protocol level, new standards like ERC-7683 are being developed to streamline cross-chain messaging and token transfers. These innovations are critical for creating a unified Ethereum ecosystem — one that feels like a single network rather than a patchwork of siloed chains.
Decentralization Remains Paramount
All these upgrades must preserve Ethereum’s core ethos: decentralization. As powerful as centralized sequencers or trusted data availability providers may be, they introduce single points of failure. The roadmap prioritizes trustless systems — especially in areas like MEV (Maximal Extractable Value), where centralization risks are growing.
Research into decentralized MEV markets, proposer-builder separation (PBS), and censorship-resistant designs continues to ensure that power remains distributed among validators and users alike.
Frequently Asked Questions (FAQ)
Q: What does TPS mean in blockchain?
A: TPS stands for Transactions Per Second — a measure of how many transactions a blockchain can process in one second. Higher TPS enables faster and more scalable networks.
Q: How close is Ethereum to reaching 100K TPS?
A: Currently, Ethereum processes around 300 TPS across L1 and L2s combined — about 0.3% of the 100K goal. While full realization is years away, key upgrades like Dencun and future danksharding phases are paving the way.
Q: Are rollups the main solution for Ethereum scaling?
A: Yes, rollups are currently the primary scaling strategy. They bundle transactions off-chain and post compressed data to Ethereum, offering immediate gains in speed and cost.
Q: What is the difference between optimistic and zk-rollups?
A: Optimistic rollups assume transactions are valid by default and use fraud proofs to challenge errors. Zk-rollups use zero-knowledge proofs to mathematically verify transactions upfront — faster but more complex.
Q: Will Ethereum ever replace traditional payment networks?
A: With continued scaling progress, Ethereum could support payment volumes comparable to major networks. However, achieving this requires not just technical upgrades but also regulatory clarity and widespread adoption.
Q: What role does OKX play in Ethereum's ecosystem?
A: OKX supports Ethereum-based assets and innovations through trading, staking, and developer initiatives — helping bring scalable blockchain solutions to a global audience.
