# A Survey of Blockchain Applications for Management in Agriculture and Livestock Internet of Things
## 4 Applications of Blockchain in Agricultural and Animal Husbandry IoT
### Efficient Resource Allocation
This system leverages blockchain technology to forge a decentralized, enduring, and tamper-resistant ledger that documents every transaction and piece of data within the livestock supply chain. This approach markedly enhances the data's transparency and security, allowing for precise tracking across each phase of the supply chain, hence improving product traceability. Furthermore, by augmenting the security of IoT devices, the system effectively thwarts hacking attempts and data leaks, safeguarding the completeness and dependability of livestock data. The IoT-BC-SLF system not only elevates the production efficiency of livestock farming but also advances animal health management and environmental conditions through automated and intelligent measures. This offers farmers more efficient and accurate livestock management strategies. As a result, the system serves a critical function in enhancing the overall sustainability of livestock farming and lays a solid groundwork for the future development of intelligent agriculture. Table 3 provides a summary of different research areas and their applications as explored in the literature pertaining to resource allocation. \begin{table}

Table 3: Resource Allocation Related Papers. This table summarizes research on resource allocation in agriculture, focusing on how IoT and blockchain can combine to enhance efficiency, transparency, and security. Below is a concise overview of key advantages, disadvantages, and notable outcomes from these studies ([100; 101; 102; 103; 104; 105; 106; 107; 108]). Advantages:
* Enhanced traceability and accountability: blockchain-led records mitigate fraud and oversight issues, as demonstrated in tea production ([85]) and livestock resource management ([108]). * Secure and transparent resource management: integrating blockchain with IoT devices ([105; 106; 107]) enables accurate water-use tracking and seed quality monitoring, offering tamper-proof data and reducing reliance on centralized authorities. * Potential for cost savings and sustainability: decentralized systems can cut intermediaries, streamline processes (e.g., water management), and promote more responsible resource usage. Disadvantages:
* Integration and technical complexity: incorporating blockchain into traditional IoT infrastructures requires specialized protocols for low-power devices and advanced expertise, posing adoption challenges ([105; 106]). * Scalability and performance constraints: large transaction volumes and limited network capacity can hinder broader deployment. * Energy and infrastructure demands: some consensus mechanisms or additional hardware may raise operational costs, possibly limiting feasibility for smaller-scale or resource-constrained settings. Best Results:
* IoT-blockchain synergy for resource optimization: Real-time data monitoring combined with decentralized validation supports more equitable and efficient distribution of water and feed resources ([105; 106; 107; 108]).
