A nonce in blockchain technology is a number used only once in cryptographic communication. In the context of mining for cryptocurrencies, it refers to a number that blockchain miners are attempting to find to solve the cryptographic puzzle that allows them to add a new block to the blockchain. The nonce is a critical component of the proof-of-work process; miners adjust the nonce repeatedly to achieve a hash below a target set by the network. This process secures the network and verifies transactions without the need for a central authority. For a more in-depth look at how nonces function and their role in securing blockchain transactions, this article offers detailed insights: https://paybis.com/blog/glossary/what-is-a-blockchain-nonce/ It explains the concept thoroughly, enhancing understanding of the mining process and blockchain security.
