# Layered design In order to facilitate future development and provide a good development environment for developers all over the world, Helicon adopts a layered design and consists of 5 layers: • Data layer: This layer contains the basic data units and data structures of Helicon. • Transport layer: P2P network protocols and algorithms used for connection, data transmission, load balancing and encryption. • Consensus layer: the consensus algorithm embedded in Helicon. • Cross-chain layer: Provide cross-chain liquidity for NFT on Helicon. • Application layer: Configure programs or dAPPs developed by third-party developers to provide developers with SDK and API. Currently, Helicon's application layer includes Genesis Games. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
