# Supply Chain Action Builder (Proof of Concept) {% embed url="" %} Traditional supply chain systems struggle with **data transparency, ownership verification, and maintaining comprehensive audit trails across multiple stakeholders**. There is a critical need for a system that can track **multi-stage workflows, prove ownership at each step, and maintain immutable records of transfers while storing stage data securely** on the blockchain. ### Solution [Supply Chain Action Builder](https://hub.bsvblockchain.org/demos-and-onboardings/demo-solutions/demos/dynamic-supplychains/business-dynamic-supplychains) is a blockchain-based supply chain management system built on BSV Blockchain that enables users to **create, transfer, and track multi-stage action chains with on-chain data storage and ownership verification**. The demo above showcases how blockchain technology can provide transparent, auditable, and immutable tracking of supply chain workflows while maintaining clear ownership and transfer records. ### How It Works * Users create **multi-stage action chains representing supply chain workflows**, with each stage recorded as a blockchain transaction. * Each action chain requires a minimum of 2 stages and a title to be finalized. * **Stage data is stored on-chain** using the PushDrop protocol from the BSV SDK. * Users can either **retain ownership of chains or transfer them to other users** by providing the receiver's public key. * **Ownership is tracked** through a locks collection for **active ownership** and a transfer collection for **historical records.** * **Real-time updates** show pending chains with automatic refresh every 30 seconds. ### Key Benefits * **Transparent Tracking:** Every stage of the supply chain is recorded immutably on the blockchain with complete transaction history. * **Ownership Verification:** Clear proof of ownership through cryptographic locks and transfer records. * **Flexible Workflows:** Support for custom multi-stage processes or pre-built templates for common supply chain scenarios. * **Auditability:** Complete historical record of all transfers with status tracking for continued chains. * **User Control:** Users decide whether to retain or transfer ownership at each stage of the process. ### Target Users * **Supply chain managers** tracking product lifecycle from production to delivery * **Manufacturing companies** managing multi-stage production processes * **Quality control teams** requiring transparent audit trails * **Organizations** needing verifiable proof of ownership and transfer in supply chains * **Businesses** seeking blockchain-based supply chain transparency solutions ### Use Cases * Tracking **agricultural products** from soil to table with multiple verification stages * Managing **plastic product lifecycle** from production through recycling * Monitoring **aircraft parts through manufacturing**, testing, and certification stages * Recording **pharmaceutical supply chain** with temperature and handling verification * Documenting **electronics assembly** with component sourcing and quality checks ### Current Impact Supply Chain Action Builder demonstrates how blockchain technology can revolutionize supply chain management by providing unprecedented transparency, ownership verification, and auditability. The system showcases practical implementation of on-chain data storage and multi-party workflow coordination, paving the way for more trustworthy and efficient supply chain operations. #### Related Resources * Technical Documentation: [technical-dynamic-supplychains.md](https://hub.bsvblockchain.org/demos-and-onboardings/demo-solutions/demos/dynamic-supplychains/technical-dynamic-supplychains) * Repository: [GitHub - bsv-blockchain-demos/dynamic-supplychains](https://github.com/bsv-blockchain-demos/dynamic-supplychains) * Live Demo: [https://dynamic-supplychains.bsvb.tech](https://dynamic-supplychains.bsvb.tech/) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
