3.5 Technical Architecture

The ChiChiPingPing Global Edu Network is built on the Solana blockchain, with an architecture designed for the characteristics of educational data, child user protection, and global scalability.

3.5.1 Hybrid Storage Model for Educational Data

To protect learner privacy and secure child data, a three-layered storage architecture is implemented:

• On-Chain Layer: Only essential data such as token transactions, NFT ownership, and critical learning certificates’ hash values are stored on-chain, complying with GDPR’s principles of purpose limitation and data minimization.

• Distributed Storage Layer (IPFS): Educational content metadata, NFT images, and learning materials that require integrity verification but contain minimal personal data are stored on IPFS.

• Encrypted Off-Chain Layer: Detailed learning records, personal learning data, and sensitive child user information are stored off-chain with AES-256 encryption and access controls.

3.5.2 Technical Implementation for Educational Solutions

Each core solution of the CPT ecosystem is implemented on the following technical basis:

• Edu Passport NFT System: Extends Solana’s Metaplex protocol by adding an education-specific metadata layer, incorporating zero-knowledge proof (ZKP) technology to ensure both reliability and privacy of learning assessments, and automating tier upgrades via smart contracts.

• P&L-to-Earn Reward Engine: Utilizes machine-learning-based evaluation systems to analyze learner activity, engagement, and achievement, employs multi-dimensional algorithms to prevent gaming, and automatically adjusts reward pools based on token economics.

• Global Content Marketplace: Features a decentralized content storage system and an automated royalty distribution system, a smart contract-based subscription model, and an on-chain reputation system to ensure content quality.

• RWA Integration Technical Solutions: Revenue data from IP utilization is transmitted to the blockchain via secure oracle networks, with transparent reward distribution processes secured by multisignature and timelock mechanisms, and quarterly settlement data permanently recorded on-chain.

Core smart contracts undergo a minimum of two independent security audits before release and comply with international educational data standards (xAPI, SCORM, LTI) to ensure compatibility with existing educational systems.

The technical architecture underpins both the innovation in learning experiences and the tokenization of IP value, providing a secure and transparent infrastructure for global learners, educators, and ecosystem participants.
