We often come across the terms fungible Tokens and non-fungible tokens in blockchain. What are they? The following table explains what are they and how they differ.
|Fungible Tokens||Non-fungible Tokens|
A fungible token can be exchanged with any other fungible token of the same type. It it like exchanging a dollar bill with another dollar bill and the value is still the same.
A non-fungible token cannot be exchanged with another non-fungible token of the same type. It is like your passport or ID, they cannot be exchanged.
Each fungible token is identical to all other fungible tokens of the same type. For example, your one dollar bill is the same as John’s one dollar bill.
Each token is unique and different from all other tokens of the same type. For example, your bank account is not the same as John’s bank account
A fungible token can be divided into smaller units and the total value is still the same. For example, you can divide a dollar bill into two 50 cents or five 20 cents and the total value is still the same.
Non-fungible token cannot be divided into smaller units. The basic unit is one token and one token only. For example, your driving license.
