• Built and optimized the Roll-DPoS consensus mechanism, crucial for supporting the linear scalability of thenetwork. This enhancement significantly improved network performance and reliability, aligning with thelatest scalability requirements.• Spearheaded the successful migration of iotex-core modules to the Cosmwasm module, a pivotal movethat markedly enhanced system compatibility and functionality.• Developed the Itox AMM and NFT Contract bridging Ethereum and Iotex through the Iotex Tube, utilizingSolidity and Rust for seamless interoperability.• Engineered an upgraded host wallet security framework by integrating sophisticated cryptographic digitalsignatures, substantially strengthening system security and reliability. This crucial development reinforceduser and stakeholder confidence in our platform's integrity.• Executed continuous integration and deployment of binary and public RPC endpoint middleware updates inthe staging environment (testnet) using GitHub Actions and AWS EKS, ensuring a robust and efficient development pipeline.

• Enhance Hyperledger Fabric by developing or refining modules, boosting its efficiency and capacity forlarger-scale applications. This involves improving transaction processing speeds and scalability toaccommodate growing network demands.• Focus on seamless integration of blockchain technology with existing educational Information andCommunication Technology (ICT) systems. This ensures fluid exchange of data, such as student recordsand learning materials, between blockchain platforms and educational software.• Develop a Decentralized Identifier (DID) management smart contract for registering and authenticatingstudent identities, alongside verifying ownership and details of educational certificates on the blockchain.• Implement advanced encryption techniques to protect sensitive educational data stored on the blockchain,ensuring it remains secure, private, and resistant to unauthorized changes.• Conduct an in-depth study on utilizing Non-Fungible Tokens (NFTs) for the tokenization of music assets inthe educational sector. This includes exploring NFT capabilities across various blockchain networks, both Ethereum Virtual Machine (EVM)-compatible and others, for enhanced digital asset management.
