Different Types of Nonce
1. Transaction Nonce
- The transaction nonce is a value that is unique to every transaction in every blockchain network.
- Its main function is for the purposes of non-replayability, giving an assurance that only approved transactions are engaged in.
- The account’s transaction nonce is incremented with every fresh transaction. The nonce increases with the last digits of the nonce of the transactions being identified as duplicate and sent back to the user.
2. Block Nonce
- Block nonce is a value added to the block header during the mining process which is called a pointer.
- It is employed in the PoW mechanisms in order to calculate the hash value that matches the desired difficulty level of the network.
- With each change of the block nonce, miners are persistently targeting hash values under the target difficulty, this way they are able to create a valid block that will be added to the blockchain.
Distinguishing transaction nonce from block nonce is the key to understanding their role in the blockchain ecosystem that maintains the networks’ security and integrity. Transaction nonce gives an edge in the of prevention transaction replay attacks while block nonce plays a crucial role as the proof of work algorithm creates computationally challenging blocks giving the network security overall.
What is a Nonce in Blockchain?
In the domain of blockchain technology, several terms and concepts have a significant impact on the security and integrity of the network. One such term is “nonce,” which holds significance in the process of mining and validating transactions. This article focuses on discussing the nonce in Blockchain.
