Abstract: Based on the four characteristics of blockchain technology (BT), namely decentralization, traceability, tamper-proofness and incentive mechanisms, this paper constructed a blockchain-based waste classification management platform with the functions of points incentive, publicity and education, online transaction and data traceability and selected a pilot district in Hefei City to test the effectiveness of the platform through questionnaire survey, field sampling and physical component analysis from January to September 2022. The results show that the recycling potential of recyclable waste increases by 20.4% compared to pre-test, and the food waste mixing rate decreases by 23.5%; the public support and participation rate exceeds 95% as of September 2022, and the successful traceability rate of violations reaches 83.2%. Meanwhile, the paper introduced the entropy-cloud model for the first time to evaluate the blockchain platform. The results show that the comprehensive determinations of waste classification management in the S1(January-March), S2(April-June) and S3(July-September) trial phases are 2.53, 2.66 and 2.82, and the comprehensive evaluation grades are IV (poor), III (fair) and II (good), respectively. The platform can solve the universal problems of poor classification quality and low public participation, and meet the requirements of the era of mandatory waste classification in China. The entropy-cloud model can consider the randomness of questionnaire and
