Phala Network, a decentralized computing platform built on Polkadot, has launched the first Op-Succinct Layer 2 (L2) rollup on Ethereum. This groundbreaking development is set to reshape Ethereum’s scalability framework while unlocking new possibilities for developers and users across the blockchain ecosystem. By combining cutting-edge privacy-preserving technologies with high-performance infrastructure, Phala is positioning itself at the forefront of the next evolution in decentralized computation.
What Is the Phala Network L2 Rollup?
The newly launched Layer 2 rollup leverages two powerful technologies: Trusted Execution Environments (TEEs) and Zero-Knowledge Proofs (ZKPs). This fusion enhances scalability, strengthens security, and significantly reduces transaction costs—all without compromising privacy or decentralization.
By integrating GPU-based TEEs with zk-proofs, the rollup enables high-throughput computations while maintaining cryptographic trustlessness. This means sensitive data can be processed securely off-chain, with only verified proofs submitted to Ethereum’s mainnet.

Developed in collaboration with Succinct Labs and Conduit, the rollup benefits from advanced ZKP capabilities and a robust Rollups-as-a-Service (RaaS) infrastructure. Succinct Labs contributed their expertise in succinct proof systems, enabling efficient verification of off-chain computations. Meanwhile, Conduit provided the modular framework necessary to deploy and manage rollup instances seamlessly.
Key features of the Phala L2 rollup include:
- Fast finality: Transactions are confirmed quickly due to optimized proof generation and validation.
- Lower fees: Batch processing of transactions on Ethereum reduces gas costs for end users.
- Cryptographic security: ZKPs ensure that all state transitions are valid without revealing underlying data.
- Seamless asset migration: Users can easily transfer assets from Phala’s Polkadot-based Khala chain to Ethereum via Ethereum Vault contracts.
This integration marks a significant step toward interoperability between Polkadot and Ethereum ecosystems, enabling cross-chain dApps and shared computational resources.
Why Ethereum Needs Advanced Layer 2 Solutions
Ethereum’s base layer has long faced scalability limitations. With a throughput of approximately 12 transactions per second (TPS), the network often experiences congestion during peak activity—leading to high gas fees and delayed confirmations.
Layer 2 rollups address these challenges by processing transactions off-chain and submitting compressed proofs back to Ethereum. This model dramatically increases throughput while preserving the security guarantees of the underlying blockchain.
Recent data underscores the growing dominance of L2 solutions:
“The adoption of Ethereum rollups has accelerated significantly over the past year. ~5x more transactions per second are happening on L2 rollups than on the Eth baselayer. Over the past 12 months, there have been 48x more on-chain calls to CL Data Feeds on L2 rollups compared to the base layer.”

As more decentralized applications (dApps) migrate to Layer 2, Ethereum’s overall utility expands. This shift supports innovative use cases such as:
- AI-driven smart contracts that require intensive computation
- Privacy-preserving DeFi protocols
- Confidential identity verification systems
However, this transition isn’t without trade-offs. One potential downside is the reduction in transaction fee revenue for Ethereum validators, as much of the economic activity shifts off-chain. If not addressed, this could impact long-term network sustainability.
Additionally, the rise of alternative data availability layers—such as EigenDA or Celestia—may challenge Ethereum’s role as the default settlement layer for rollups. Still, Ethereum remains the most secure and widely adopted base layer, giving it a strong competitive edge.
How This Benefits Developers and Users
For developers, Phala’s Op-Succinct rollup offers a powerful environment for building privacy-centric, high-performance dApps. The combination of TEEs and ZKPs allows for secure execution of complex logic—ideal for applications involving machine learning, confidential finance, or regulated data processing.
Users benefit from faster, cheaper interactions with dApps, along with stronger privacy guarantees. Unlike traditional rollups that expose transaction details publicly, Phala’s architecture ensures computational integrity while keeping input data confidential.
Moreover, the migration path from Khala (Phala’s Polkadot parachain) to Ethereum simplifies cross-chain asset movement. Through Ethereum Vault contracts, users can lock PHA tokens on Khala and mint equivalent representations on Ethereum—enabling frictionless access to both ecosystems.

Frequently Asked Questions (FAQ)
What is an Op-Succinct Layer 2 rollup?
An Op-Succinct L2 rollup combines optimistic rollup principles with succinct zero-knowledge proofs to achieve scalable, secure, and cost-efficient transaction processing on Ethereum. It uses ZKPs to verify off-chain computations cryptographically, ensuring correctness without sacrificing speed.
How does Phala Network enhance Ethereum’s scalability?
Phala improves scalability by offloading computation from Ethereum’s mainnet using a ZKP-powered rollup. This reduces congestion, lowers gas fees, and increases transaction throughput—all while maintaining compatibility with existing Ethereum tooling and wallets.
What are Trusted Execution Environments (TEEs)?
TEEs are secure hardware enclaves that isolate sensitive computations from the rest of the system. When combined with ZKPs, they enable private, verifiable computing—allowing dApps to process confidential data without exposing it to external parties.
Can I use PHA tokens on Ethereum now?
Yes. Through Ethereum Vault contracts, users can bridge PHA tokens from Phala’s Khala chain (on Polkadot) to Ethereum. This enables participation in Ethereum-based DeFi protocols while retaining ownership of native assets.
Is this rollup fully decentralized?
While early stages may involve some centralized components for stability, Phala aims to progressively decentralize governance and operations. Future upgrades will focus on permissionless node participation and community-driven decision-making.
Why combine ZKPs with TEEs instead of using one or the other?
Using both technologies creates a hybrid trust model: ZKPs provide mathematical proof of correctness, while TEEs offer real-time performance for complex workloads. Together, they balance security, privacy, and efficiency better than either solution alone.
Final Thoughts: A New Era for Decentralized Computing
Phala Network’s launch of the first Op-Succinct L2 rollup represents a pivotal moment in blockchain evolution. It bridges the gap between high-performance computing and cryptographic security, offering a scalable pathway for privacy-focused dApps on Ethereum.
As Layer 2 adoption continues to grow, solutions like this will play a crucial role in expanding what’s possible on public blockchains. From AI-integrated smart contracts to confidential financial systems, the future of decentralized computing is taking shape—one rollup at a time.
