Abstract: This study examines using blockchain to establish trust in cross-border e-commerce and strengthen regional trade networks to address major issues such as information asymmetry, lack of a trust mechanism, and inefficiency, which are found in traditional cross-border trade. By integrating blockchain technology with network optimization theory, the study constructs a cross-border e-commerce credit system architecture based on a consortium chain structure, designs a multidimensional credit evaluation model, and establishes smart contract-driven credit data collection and processing mechanisms. Empirical research demonstrates that this credit system, when applied to large-scale cross-border e-commerce platforms, improves information transparency by 85%, achieves 91% risk warning accuracy, and reduces dispute resolution time from 14 days to 3 days. In Small and Medium Enterprise (SME) alliances, the proportion of trade executed through smart contracts increases from 15% to 67%, with average credit limits granted by financial institutions increasing by 41%; in regional trade ecosystems, trade activity increases by 27%, with network density rising from 0.31 to 0.45. Research contributions include proposing a blockchain-driven multidimensional credit evaluation model for international e-commerce, cross-border credit collaboration mechanisms based on smart contracts, and multi-level credit data sharing solutions adapted to different trading requirements. These findings provide technical implementation pathways for cross-border e-commerce platforms, innovative regulatory approaches for trade management departments, and feasible support solutions for SMEs participating in international trade, offering extensive application value for inclusive global trade development, regional economic structure optimization, and international trade efficiency enhancement.
