I am currently developing a Payment System with an Escrow System and Order Handling. Later even a marketplace. So far so good the dApp already exists but saving order information and customer data into blockchain is not the best way for it. I am planning to outsource order handling and customer registration. With each transaction, some pieces of Order information need to be saved, retrieve, and rechecked. It is also not cheap. I came now to Holochain but I’ve checked already the documentation but I am not an expert in a few minutes now.
As I understood the hApp need to be run in the background to validate the data over DHT. I found this link and my question is is a local chain or shared DHT a better way for securing customer data and order information? I guess the customers don’t need to run additional hApps to join and it is enough that we run it? It is also possible to publish files, e.g. images?
