​This guide was written to introduce the concept of tracking physical and digital goods as well as crypto assets for transactions or marketing and branding purposes on a Web3 blockchain technology storage platform. This represents a significant shift in technology, where blockchain assets are available on a public digital ledger, open for all to view and verify. It marks a paradigm shift from the private cloud storage currently used in Web2 infrastructure platforms. This guide provides minimum requirements for the secure verification of a Certificate of Authentication (COA) used to track any product through their supply chain by utilizing Blockchain Technology.

The implementation of blockchain technology can enhance the transparency, traceability, and trustworthiness of the supply chain, ensuring product quality and authenticity while reducing the potential for fraud, tampering, and other malicious activi-ties. Each Certificate of Authenticity (COA) is minted on the blockchain, featuring a screenshot of the summary page on the front of a Non-Fungible Token (NFT) with the unique traits of that lab report tagged as metadata. Examples of this metadata include the name of the lab, the name of the client, the unique identifier of the sample tested, and the date the test was performed. To enhance the tracking and security of these COAs, various tracking devices can be linked to the COA on the blockchain, depending on the product's specific needs and the nature of the supply chain. These devices include RFID tags, QR codes, holograms, micro transponders, and embed-dable watermarks. Each serves a unique purpose, from instant verification via QR codes to advanced security and tracking through RFID and micro transponders. Holograms and embed-dable watermarks provide additional layers of security, making
