Layered Architecture

1. Layer 1 (Ethereum Mainnet):

   • Security and Settlement: CarrChain inherits Ethereum's security through the Rollup or AnyTrust protocols of Arbitrum.

   • Data Finality: Ethereum acts as the ultimate settlement layer, ensuring the integrity and finality of transactions executed on CarrChain.

2. Layer 2 (Arbitrum):

   • Scalability with Rollup Technology: Arbitrum uses Rollup technology to batch transactions and compress data, reducing fees and improving throughput.

   • Data Availability Models:

     • Rollup Mode: Posts all transaction data on Ethereum, offering full decentralization and security.

     • AnyTrust Mode: Reduces costs by maintaining data availability off-chain with a trusted data committee.

3. Layer 3 (CarrChain):

   • Custom Native Gas Token: CarrChain uses its own token for paying transaction fees, allowing for specialized economic models and incentives within the ecosystem.

   • EVM+ Compatibility: Supports smart contracts written in Solidity as well as additional languages like Rust, C, and C++ through Arbitrum Stylus.

   • Application-Specific Logic: Optimized for automotive use cases, providing tailored features for vehicle identity management, marketplaces, and automotive financial products.
