What does IOU mean? 

blockquote icon

IOU stands for “I Owe You” and indicates a debt or amount owed.

IOUs can be issued in any type of document, paper, electronic, or verbal agreement. 

An IOU typically isn’t legally binding, though this depends on your region and jurisdiction. It’s intended to be a reminder and informal agreement that one party owes another and can specify the amount or omit it. 

IOUs are typically issued for a monetary amount but can also apply to physical items or goods. Now, IOUs can be issued for crypto using tokens specifically created to indicate debt on the blockchain.

What is the logic behind tokenizing IOU?

Tokenizing IOUs makes it possible to have a record of debt owed on the blockchain.

Rather than keeping the agreement off-chain, where it can’t be definitively verified, there’s a trustworthy, transparent record. 

The goal of blockchain technology is to maintain a public ledger of financial transactions, so it only makes sense to have IOUs tokenized and tracked, especially if you’re tracking a crypto debt. 

Let’s say you owe someone a certain amount of Ethereum. You can create an IOU token that you send to them as proof that you owe them a debt, and they can send it back to you to request the debt payment. 

IOU tokens aren’t legally binding, but they’re an easy way to borrow and lend and keep track of these amounts.
