Introduction

We are thrilled to announce a significant upgrade for Fuse Network. Fuse is launching a zkEVM Layer 2 Network using the Polygon CDK. This transformation will enhance our network’s scalability, security, and interoperability. Our first step is the launch of our Testnet, Flash.

Why Polygon CDK and zkEVM?

Integrating Polygon’s Chain Development Kit (CDK) allows us to build a highly efficient, Ethereum-compatible Zero-Knowledge (ZK) Layer-2 network. Key advantages include:

  • Scalability: zkEVM will enable higher transaction throughput and lower latency.

  • Security: Zero-Knowledge Proofs (ZKPs) provide enhanced security by validating transactions without revealing details, preserving user privacy.

  • Interoperability: Full compatibility with EVM chains will ensure seamless network interactions and asset transfers.

Flash Testnet

The Flash Testnet marks our first step in launching a zkEVM L2. The settlement Layer for Flash L2 is Sepolia Network.

Flash zkEVM is to Sepolia Network a Layer 2 network and a scalability solution utilizing zero-knowledge technology to provide validation and fast finality of off-chain transactions.

Since Polygon zkEVM supports most Ethereum EIPs, precompiles, and opcodes, developers building on FLash will benefit from the seamless deployment of smart contracts, developer tools, and wallets that already work on Ethereum but in an environment with significantly lower costs.

Polygon CDK Architecture

The Polygon CDK architecture comprises several key components:

  • Sequencer: Responsible for ordering transactions and ensuring they are processed efficiently.

  • Aggregator and Prover: Aggregates transactions into batches and generates cryptographic proofs for validation.

  • L1 Smart Contracts: Interacts with Sepolia Network for Layer 1 for state commitments and proofs, ensuring the integrity and security of the Layer 2 operations.

  • Unified Bridge: The Fuse Charge Bridge will facilitate seamless asset transfers between Fuse and Ethereum, maintaining interoperability and liquidity.

Sequencing and Decentralization

Initially, the Fuse team will operate sequencing on the Flash Testnet. Our long-term goal is full decentralization, ensuring stability and security during transition.

Changes and Compatibility

As part of this transition, we will deprecate certain legacy transaction types. Detailed information on these changes will be provided in our documentation.

Getting Started with Flash

We invite the Fuse community to participate in testing the Flash Testnet. Here’s how you can get started:

Conclusion

This is an exciting time for Fuse Network. Transitioning to an advanced Layer 2 using Polygon CDK and zkEVM will position Fuse as a leader in scalability, security, and interoperability. We look forward to your participation in the Flash Testnet and valuable feedback.

Thank you for your continued support.

The Fuse Team. :rocket:
