Hello, everybody. This is my first post to the forum. I have read a bit about cryptocurrencies but I am still rather newbie to the field. I would like to ask: Can I somehow "mark" a transaction? I will give an example to make my question clear. For example: Name me Bob. I want to give 1 BTC to Alice, for her to buy a new motherboard and processor. So I send 1 BTC to her wallet. Can i somehow give a "title" to this transaction, for example "Money to buy a computer"? Just like the title of an e-mail for example.
Thank you kindly in advance.
Many wallet will support creating a label for an address within your own wallet as a reminder to yourself.
There is currently no supported way to send the label through the bitcoin protocol to Alice though.
What Alice should do is create a new address specifically for this transaction. She can label the address in her own wallet as "Payment from Bob for computer". Then when you send bitcoins to that address, she will know that she has received the payment for the computer that she is selling to you.
