# Importance of Non-Reversible Transactions

<figure><img src="/files/Djfa1WBldXTtQGQkpeqS" alt=""><figcaption></figcaption></figure>

*Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non-reversible services.*

\- Satoshi Nakamoto, Bitcoin Whitepaper

**Non-reversible transactions** are a critical aspect of online commerce that is often overlooked. The current payment systems, which rely on financial institutions, cannot facilitate completely non-reversible transactions due to the necessity of mediation in disputes. This limitation has several implications:

* **Increased Transaction Costs**: The requirement for mediation increases the overall cost of transactions, making it impractical for small casual transactions. Merchants are often forced to absorb these costs, which can lead to higher prices for consumers.
* **Loss of Non-Reversible Payment Options**: Merchants selling non-returnable goods or services face significant challenges in receiving non-reversible payments. This gap in the payment system creates a barrier to commerce, particularly for digital goods and services.
* **Fraud Risk**: The possibility of chargebacks creates an environment where merchants must be wary of customers, leading to a culture of suspicion and excessive scrutiny. This not only affects the merchant's operations but also impacts the overall customer experience.
