The follow up questions:
Is the post on relay traceable and immutable? If so, how to prove and what mechanism is used?

Because on NOSTR, if the users want to get some information, they have to subscribe the particular relays first. If users don't follow some relays, the information can be missed. However on the Blockchain, all blocks can communicate with each other so it has traceability and transparency. nostr:note1kwxxjnl7qt2c6m53qde6r85gfqcvtqydchn8a847rpm69cf23ayqgyst4y 

 #AskNostr: I'm conducting a university project on the potential integration of NOSTR with blockchain technologies in supply chain solutions. I have a couple of big questions for the community:

Can we use NOSTR instead of blockchain? What are the advantages and disadvantages of opting for NOSTR as a decentralized messaging protocol compared to traditional blockchain systems?
Benefits of NOSTR: If NOSTR can be used in supply chains, what specific benefits would it offer over blockchain? How could its features enhance real-time communication, event logging, or overall supply chain efficiency?
Collaboration Potential: If a direct replacement isn’t feasible, how can NOSTR and blockchain technologies complement each other in supply chain processes?
Information Accuracy: Lastly, how can we verify the accuracy of information shared through NOSTR relays to ensure reliability in supply chain management?

Your insights will be invaluable for understanding how these technologies can work together to create a more transparent and efficient supply chain ecosystem. Thank you for your contributions!
