Traditional Chinese medicine is widely used in the medical field for its good curative effect and extremely small side effects,but the sources and preparation processes of traditional Chinese medicine materials lack transparency,Some traditional Chinese medicines have the defects of being easy to counterfeit and difficult to trace.Thus, a blockchain-based traditional Chinese medicine traceability model(BTCMT) is proposed in the paper.This model is based on the blockchain and uses a distributed storage mechanism. Under the control of the practical Byzantine algorithm and smart contract, it has achieved the distributed management of the whole process of planting, collecting, primary processing, preparation and sales of traditional Chinese medicine, ensuring the transparency, decentralization and anti-counterfeiting of traditional medicine on each block, and has realized the traceability and information sharing of traditional Chinese medicine. After simulation experiments, the accounting success rate of BTCMT was 100%, Failure rate is 0%, the shortest traceability response time was 212ms, and the maximum system traceability throughput was 4908.02bps. The model has good robustness and provides a reference for the traceability model of traditional Chinese medicine.
