12.2 Smart contracts in supply chain automation

Smart contracts are revolutionizing supply chain management by automating processes and increasing efficiency. These self-executing contracts, written directly into code, eliminate intermediaries and streamline operations like payments, inventory management, and quality control.

The implementation of smart contracts in supply chains offers numerous benefits, including increased efficiency, reduced errors, and enhanced transparency. However, challenges such as technological limitations, legal uncertainties, and resistance to change must be addressed for successful adoption.

1 of 3

• Self-executing contracts with terms of agreement written directly into code
• Automatically enforce terms and conditions without need for intermediaries (lawyers, brokers)
• Can automate various processes in supply chain management
  • Trigger payments automatically upon fulfillment of certain conditions (delivery of goods)
  • Monitor and replenish inventory levels based on predefined rules
  • Perform and record quality control checks on the blockchain

Automation through smart contracts

• Automated payments with smart contracts
  • Program smart contracts to release payments to suppliers once goods are received and verified
  • Eliminates need for manual invoice processing and reduces payment delays
  • Ensures timely and accurate payments to suppliers (within 24 hours of delivery)
• Inventory management with smart contracts
  • Track inventory levels in real-time and trigger automatic reordering when stock falls below certain threshold
  • Ensures optimal inventory levels and reduces risk of stockouts
  • Enables just-in-time inventory management (reduces storage costs)
• Quality control with smart contracts
  • Record and verify quality control checks at various stages of supply chain (manufacturing, transportation)
  • Creates immutable record of quality assurance, increasing transparency and trust among stakeholders
  • Enables quick identification and resolution of quality issues (defective products)

Benefits in supply chain management

• Increased efficiency
  • Automate manual processes, reducing time and resources required for supply chain operations
  • Leads to faster transaction processing and reduced operational costs
  • Streamlines supply chain workflows (order processing, invoicing)
• Reduced errors
  • Eliminate need for manual data entry and processing, minimizing risk of human error
  • Improves accuracy of supply chain data and reduces likelihood of disputes
  • Ensures consistent and reliable data across the supply chain (inventory levels, shipment tracking)
• Enhanced transparency
  • Provide tamper-proof record of all transactions and events in the supply chain
  • Increases transparency and enables all stakeholders to access real-time, reliable information
  • Facilitates collaboration and trust among supply chain partners (manufacturers, distributors, retailers)

Risks of smart contract implementation

• Technological limitations
  • Performance and scalability of blockchain networks may be a challenge for large-scale supply chain operations
  • Interoperability issues between different blockchain platforms and legacy systems may hinder adoption
  • Requires significant investment in infrastructure and technical expertise (blockchain developers)
• Legal and regulatory challenges
  • Legal status of smart contracts varies across jurisdictions, creating uncertainty in their enforceability
  • Compliance with existing regulations, such as data protection laws, may be complex when using smart contracts
  • Lack of clear legal framework for smart contracts in many countries (United States, European Union)
• Resistance to change
  • Implementing smart contracts requires significant changes to existing processes and systems
  • Stakeholders may be resistant to adopting new technologies and adapting to new ways of working
  • Requires extensive training and change management efforts to ensure successful adoption (employee buy-in)
