# Execution Chain

\
Purpose of the Execution Chain:
-------------------------------

&#x20;The Execution Chain serves as the primary interface for users and developers engaging with Polar Network. Engineered for efficient transaction processing and smart contract execution, it forms the foundation for real-time interactions on the blockchain.

## Technical Design and Characteristics:

&#x20;1\. **Transaction Processing Speed:** With a throughput capacity of approximately 100,000 transactions per second (TPS), this chain is optimized to handle high-volume transaction processing, crucial for decentralized exchanges and high-frequency trading platforms.

&#x20;**Transactions are typically confirmed within 1 to 2 seconds, ensuring quick response times vital for time-sensitive applications.**

2. **Smart Contract Execution:** Smart contracts on the Execution Chain undergo rapid execution, aligning with the chain's high transaction processing speed. This swift execution ensures efficient operation of decentralized applications (dApps), with minimal delays in contract execution.
3. **Advanced Sharding Technique**: Leveraging state sharding, the chain divides the network state into multiple shards, each independently processing transactions. This approach enables parallel transaction handling and significantly enhances the chain's capacity.&#x20;

**State sharding ensures horizontal scalability, accommodating increasing transaction volumes without sacrificing performance.**

## Programming Language Support:

&#x20;4\. The Execution Chain offers support for various programming languages for smart contract development, including Rust, Solidity, and Vyper. This multi-language support enhances accessibility and flexibility for developers, allowing them to work in their preferred languages.

5. **Interoperability Features**: Engineered for interoperability, the Execution Chain seamlessly integrates with other chains within the Polar Network ecosystem through robust cross-chain communication protocols.

## Developer Impact:&#x20;

The design of the Execution Chain greatly benefits developers, providing them with a high-performance platform for building and deploying dApps. The combination of high TPS, rapid smart contract execution, and multi-language support fosters an optimal environment for developing a diverse range of real-time blockchain applications.
