【Abstract】This study develops a new analysis method, the latent Dirichlet allocation topic model, and uses it to perform technology assessment and roadmapping analysis of the blockchain field based on patent data. Our results describe the current state of technology development and predict future development trends. The new analysis method is based on technology life cycle theory, the latent Dirichlet allocation topic model, and text similarity calculation, enabling a more effective analysis of the status of R&D in the blockchain field. We find that research on the theory of blockchain, blockchain trading systems, blockchain system structure, and intelligent financial systems based on blockchain should be prioritized to realize the full benefits of this technology.
