# Credit Debit

The credit-debit model provides a double-entry accounting system for tracking asset movements on the blockchain.

This model is particularly useful for analyzing token flows, calculating balances, and understanding asset distribution patterns.

**Credit Debit vs Transfers** Credit-debit tables transform single transfer events into two corresponding entries:

* A debit (negative) entry for the sending address
* A credit (positive) entry for the receiving address

**Example** Using an ERC20 token as an example, a **token transfer** will be represented as follows:
