Background of the problem: I am undertaking a blockchain course at University and I have taken up a case study for blockchain that relates to logistics. The requirements are simple, yet I am confused with the storage segment of blockchain. Given that we have a table of deliveries to be made, I incorporate certain fields of the table into the blockchain.
- Would the data (payload of the block) be stored as plaintext?
- And how would I verify that the table hasn't been tampered with and it satisfies the blockchain?
