Architectural Design Philosophy

PopChain is not a traditional "general-purpose public chain," but a next-generation public chain specially optimized for social and content economies.

PopChain is built on Cosmos SDK, adopts the DPoS (Delegated Proof of Stake) consensus mechanism, and integrates Cosmos’s IBC (Inter-Blockchain Communication) protocol, forming a decentralized infrastructure with cross-chain interoperability, modular extensibility, and high performance at low cost.

Design goals:

• Connectivity-driven: built-in support for on-chain logic of identity, content, and behavior, constructing the ConnectFi economy.

• Cross-chain interoperability: leveraging IBC to connect multiple chains, supporting cross-chain transfer of assets, identities, and behaviors.

• User experience optimization: low gas fees and second-level confirmations to meet high-frequency social interactions.

Developer-friendly: modular components plus CosmWasm smart contracts, lowering the threshold for building SocialFi applications.

Technical Architecture Overview

PopChain adopts a layered architecture, from the underlying consensus to application layer protocols, emphasizing scalability and social nativeness.

• Application Layer — Social and content applications

• Protocol Layer — Content protocol / Behavior protocol / Incentive protocol / DID protocol

• Module Layer — ContentBase / BehaviorTrack / PopID / EngageScore / PopFun

• Execution Layer — CosmWasm smart contract engine

Network Layer — DPoS consensus + Cosmos SDK + IBC cross-chain communication
