CrossFi Chain

The dual-coin model of CrossFi Chain enables a sustainable and efficient economy within the CrossFi product ecosystem. MPX, a coin with unlimited emission, serves as a unit of minting power for generating XFI and as a payment coin for transaction fees. XFI, a volatile coin with limited emission, functions as a means of payment and grants access to all Cross Finance products.

A layer 1 blockchain serves as the foundational protocol in a blockchain network, encompassing the core network architecture, consensus mechanisms, and protocol rules essential for creating, validating, and recording transactions. Examples of l1 blockchain include Bitcoin, Ethereum, and Solana. These blockchains handle fundamental activities such as transaction processing, security, and network governance, providing the infrastructure for decentralized applications (dApps) and other blockchain-based solutions.

The EVM blockchain works with the Ethereum Virtual Machine (EVM). The EVM is a decentralized computing engine that executes smart contracts on the Ethereum blockchain. It provides a platform for developers to build and release decentralized applications (dApps) using smart contracts programmed in languages like Solidity.
EVM blockchains can run EVM-based smart contracts, taking advantage of Ethereum's existing infrastructure and developer community. These blockchains remain compatible with Ethereum, allowing for interoperability and using the same tools and dApps across various EVM-compatible networks. Examples of EVM blockchains include Ethereum itself, Binance Smart Chain, Polygon (previously Matic Network), and CrossFi Chain.

A cross-chain bridge in the blockchain ecosystem enables the transfer of assets, data, and information across different blockchain networks. It enhances interoperability, facilitates asset transfer, optimizes resources, improves user experience, and integrates decentralized finance (DeFi) protocols. This promotes interoperability, enhances functionality, and provides users greater flexibility and options within the blockchain industry.

Blockchain layers refer to the different levels in the blockchain technology stack, each serving specific functions. Layer 0 includes the foundational infrastructure like hardware and networking protocols. Layer 1 is the base layer, responsible for the core blockchain functions such as consensus mechanisms and transaction recording, exemplified by Bitcoin and Ethereum. Layer 2 comprises scaling solutions built on top of Layer 1 to improve transaction throughput and reduce fees, like the Lightning Network and zk-Rollups. Layer 3 is the application layer where decentralized applications (dApps) and smart contracts operate. Finally, Layer 4 includes the interaction layer, which involves tools and interfaces like wallets and browsers that facilitate user interaction with the blockchain. These layers work together to enhance blockchain systems' scalability, security, and functionality.
