Can I use Blockchain records to verify a purchase I am new in the Bitcoin field, but I wondered, if I paid bitcoins to a store to buy something from the internet, then if the store did not send what I purchased, is there a way I could use the blockchain to verify the transaction, say to sue the store?
The transaction itself would be publicly visible, but you'd have to first prove that the address you sent the coins to is owned by the company, and that you were the one sending them, and also what the payment was for. If you had some proof that the transaction was for the item you bought, then yes, it would be easily verifiable that the transaction was legit. But bitcoin addresses are just random looking numbers and letters, so the company could claim that they didn't own the address you sent the payment to (and so they never received the money) or that the payment was for something else you purchased off them, not the item in question.
