# Overcoming the Technological Barriers in the Blockchain Supply Chain for Small Carriers
## 5 Discussion and Further Work  
In our paper, we addressed the challenge of small carriers being responsible for transporting perishable goods and explored the potential of using blockchain technology in the supply chain. One of the main issues with smaller vehicles performing shorter delivery tasks is measuring and maintaining temperatures in the transport space. We suggest implementing an online monitoring system to retain records for temperature compliance checks to address this. Temperature monitoring equipment directly on vehicles with a minimum of three checkpoints (at the refrigeration unit, centre of the vehicle, and doors) would allow monitoring of the required temperatures. Figure 14: The verification of transactions in Hashscan.io. Continuous temperature measurement is carried out in the semi-trailer if the vehicle is equipped with a refrigeration unit and temperature recorder. Telematics devices are also installed in semi-trailers, allowing temperature recording and online monitoring and control throughout the entire transport period. This is the only part of the transport chain where online temperature monitoring is enabled and is accessible to third parties by agreement. Transparency, quick data verification, and decentralised features are desirable attributes for various applications. For example, in addition to managing data quickly, the pharmaceutical industry also evaluates and verifies data from different sensors. Assessing your reasons for developing decentralised applications before choosing an innovative contract platform is essential. Differences in platform features and capabilities could affect the functionality of an app and the tasks that users can perform with it. We did not focus on security but examined the 'blockchain's applicability in the supply chain. So, what will attract potential stakeholders to use this technology in the supply chain? There is still a gap between the scientific and research fields, where blockchain is seen as having potential for the future. However, there is still some distrust among business stakeholders regarding the adoption of blockchain technology. There are still many areas that will need to be explored in terms of the relationship between blockchain and the supply chain. _Challenges for Small Carriers_  
The specific challenges for small carriers in adopting blockchain technology are:  
* Transformation and adaptation to market needs,
* Modernising the fleet,
* Testing new equipment,
* Automatisation of processes,
* Introducing the new approach to meet the industry criteria,
* Provide feedback to supply chain consortia to enable efficient data verification. Small carriers can also be incentivised to participate in the blockchain supply chain through financial and non-financial incentives and benefits, offering participation in a larger market. **Integration with existing systems and Interoperability:** To effectively integrate blockchain technology into existing supply chain systems with small carriers, it is necessary to ensure seamless interoperability with other technologies such as ERP, CRM, and IoT. In addition, through decentralised applications built on smart contracts, it is possible to create automated processes, e.g., data verification, execution of tasks, thus eliminating the need for manual data evaluation, task assignment, etc. This can greatly speed up and simplify the supply chain process, for example. **Regulatory Compliance:** Compliance with relevant regulations and industry standards governing data privacy, security, and consumer protection. Some of them are mandatory in terms of legislation, but some will be indispensable from the point of view of using the blockchain platform. Compliance with regulations such as GDPR (General Data Protection Regulation) or HIPAA (Health Insurance Portability and Accountability Act) may be necessary, depending on the industry and geographic location. **Public or private:** We expect there to be concerns regarding whether the platform should be public or private.
