I am starting a project that I need to build a solution to track products (ex: from farm until it gets to the supermarket)
Basically, I need to set up a blockchain structure for my company(private) and put values in there.
Problems: In my research time (about 1 week) I could not found a variety of examples using the blockchain to store objects, the vast majority is about coins. I am studying about Solidity syntax, EVM, web3-js, Ethereum in general with a lot of tutorials.
In other words: I want to insert objects in the blockchain, like company1, company2, person1, person2. Where is it stored? If this is possible, how can I do a
SELECT * FROM Persons table Companies and list all companies?
Could any of you guys help me out pointing me to some straightforward tutorial or something helpful?
Ref to tutorials done:
Among others... Thanks in advance!
