Finality

What Is Finality?

The term “Finality” is defined as an event or action that permanently puts a stop to something. The idea of finality in cryptocurrency is explained below.

Looking at traditional finance to understand why finality is important for blockchain is helpful. Settlement finality is the type of finality in which financial institutions are most interested. It's important because the longer it takes to complete a transaction, the greater the chance that something may go wrong.

Finality - An Essential Feature of Cryptocurrency

Finality is a key component for businesses that accept cryptocurrencies because waiting forever on a blockchain network can have a negative impact on firms that accept cryptocurrency as a form of payment. Low latency is essential for the creation of a successful payment system.

To put this into perspective, going shopping would rapidly become incredibly inconvenient if you had to wait 10 minutes each time you wanted to make a purchase. Companies in the financial sector must also be able to determine whether they are the owners of specific assets quickly.

As a result of its finality, transactions are considered immutable when it comes to blockchain technology. However, most blockchain protocols only display a probabilistic level of transaction finality, which means that rather than becoming "more and more final" right away, transactions need time to become final.

Example of Finality 

A transaction is deemed FINAL in bitcoin after six blocks from the original block. This means that if a transaction is still active and there isn't a chain fork for six more transaction periods, there is a tiny chance it will be lost at a subsequent chain fork.
