Scroll is pioneering a vision of the Open Economy. A fully decentralized ecosystem where innovation thrives, collaboration flourishes, and meaningful solutions emerge for both global and local communities. At its core, it's a zkEVM (zero-knowledge Ethereum Virtual Machine) rollup that scales Ethereum while maintaining its foundational principles of decentralization and censorship resistance.

Unlike other scaling solutions that compromise on security or decentralization, this approach maintains complete compatibility with Ethereum while dramatically improving transaction throughput and reducing costs. This means developers can deploy their existing Ethereum applications without any modifications, enjoying the benefits of faster transactions and lower fees.

The robust infrastructure is built on three interconnected layers:

Settlement Layer (Ethereum) The foundation of trust where security is anchored. This layer provides data availability, verifies validity proofs, and enables seamless asset transfers between Ethereum and the rollup through bridge and rollup contracts.

Sequencing Layer The operational heart, containing:

• Execution Node: Processes transactions from both users and Ethereum bridge interactions, producing L2 blocks

• Rollup Node: Batches transactions, posts data to Ethereum for availability, and submits validity proofs for finalization

Proving Layer The innovation engine that ensures transaction correctness through:

• A distributed pool of provers generating zkEVM validity proofs

• A coordinator orchestrating proving tasks and relaying proofs back to Ethereum

Zero-knowledge proofs are cryptographic marvels that allow the system to prove the correctness of thousands of transactions without revealing their details. However, generating these proofs presents significant challenges:

Proofs are generated through a sophisticated three-step process:

1. Chunk Proofs: Prove collections of ordered transaction traces across multiple blocks

2. Batch Proofs: Combine and verify adjacent chunks

3. Bundle Proofs: Aggregate adjacent batches into final proofs verifiable on Ethereum

Each stage requires intensive computation, careful orchestration, and reliable infrastructure. Managing this complexity while maintaining decentralization and cost-efficiency is where traditional approaches fall short.

This is precisely where Fermah transforms the rollup's capabilities. As a universal proof market, it abstracts away the entire complexity of proof generation, providing cheap, fast, and decentralized computational power.

Intelligent Orchestration The sophisticated coordination system automatically distributes proving tasks across its decentralized network, ensuring optimal resource utilization and minimal latency.

Universal Compatibility Unlike specialized proving solutions, Fermah can generate proofs for any proof system, chain, or virtual machine. This versatility ensures proving needs are met both today and as the ecosystem evolves.

Lean Mechanism Design Through efficient economic incentives and streamlined processes, it delivers cost-effective proof generation without compromising on speed or reliability.

The integration creates a seamless proof generation workflow:

When the network identifies the need for new proofs (chunks, batches, or bundles), the coordinator makes these tasks available to proof markets.

The Proving SDK continuously monitors the coordinator, automatically capturing new tasks and translating them into Fermah-compatible proof requests.

Fermah Core intelligently processes these requests, analyzing computational requirements and assigning tasks to the most suitable prover nodes in its decentralized network.

Selected prover nodes execute the intensive computations within secure Docker containers, generating the required proofs and returning them to Fermah Core.

The completed proofs flow back through the Proving SDK to the coordinator, which verifies and integrates them into the network, completing the cycle.

The recent launch of the SDK represents a quantum leap in addressing Ethereum's fragmentation problem. This powerful toolkit enables developers to deploy their own ZK-rollup chains while maintaining full interoperability with the broader ecosystem.

Fermah plays a crucial role in this expansion by ensuring proof generation never becomes a bottleneck. Whether powering the mainnet or supporting new chains built with the SDK, projects can simply submit proof requests and receive reliable results—allowing developers to focus entirely on building innovative products rather than managing complex infrastructure.

With Fermah handling the proving infrastructure, developers enjoy:

• Simplified deployment: No need to understand or manage proof generation complexity

• Predictable costs: Transparent, competitive pricing for proof generation

• Reliable performance: Guaranteed proof delivery backed by a decentralized network

• Scalable architecture: Proof generation capacity that grows with demand

Projects building the future of finance, gaming, social applications, and beyond now have the infrastructure they need to succeed without compromise.

The combination of zkEVM technology and decentralized proving infrastructure isn't just solving today's scalability challenges; it's laying the foundation for a more open, accessible, and innovative blockchain ecosystem.
