What is a txID? Sorry still a bit new to this.... I paid and need to send info but not sure what that is
Txid is a long string of number and letters (not your btc address) txid stands for transaction identification.
Imagine for example you are pumping gas at the gas station, you purchased a few gallons.The tx id is like the serial number on the receipt that is dispensed to you.
This serial number on the receipt can be punched into a block explorer and it will query the block that your bitcoin transaction was broadcast with.
The txid allows mr. crypto hodl, or any other bitcoiner to scrutinize and ascertain that the coins were sent.
Without the txid it would be hard to prove that you actually sent the funds, or if you missent the funds it would be hard to prove that you sent them to a differnt address.
I hope this helps.
