Research on blockchain-driven decentralised ETF trading platform architecture

This study designs and implements a blockchain-based decentralised ETF trading platform architecture, deploying smart contract clusters through the Arbitrum network to achieve ETF asset management, trading and redemption functions. Experimental evaluation shows that the platform achieves a transaction confirmation time of 19.7 seconds and a functional success rate of more than 99.8%, while reducing the transaction cost by 66.7%. The hybrid trading mechanism combines the advantages of AMM and order book to effectively increase liquidity utilisation to 56%.ZKP technology application achieves user privacy and compliance balance. The research results demonstrate that the blockchain-driven ETF trading model outperforms the traditional model in terms of asset transparency, trading efficiency and user autonomy, and provides an innovative solution for financial asset management.
