This  paper  presents  the  design  and  implementation  of  a  monitoring  and  data  collection  system  for  agricultural  product preservation during transportation to meet authenticity and traceability requirements. The system is built and performed using blockchain  and  Internet  of  Things  (IoT)  technology  to  use  and  integrate  their  benefits.  This  system  comprises  a  private blockchain network built on the Ethereum platform and powered by the GoQuorum protocol, which enables distributed data exchange  among  members  using  a  common  protocol  and  cryptographic  techniques  while  ensuring  the  transparency  and integrity of the information. A wireless sensor network has been designed and implemented for collecting data from sensors about the storage environment of agricultural products. This study also proposes using LoRa technology to build low-cost wireless communication networks with broad coverage for data collection from sensor nodes mounted to agricultural products. Furthermore,  the  integrated  online  map  web  assists  in  real-time  monitoring  and  tracing  of  information  on  the  process  of transporting agricultural products, as well as querying data for completed contracts. Experiments were conducted close to the reality of the application’s desire to deploy the system to calibrate and evaluate the functioning, with promising results.
