A public function in the context of blockchain and cryptocurrency refers to a function that is accessible to anyone on the network. This means that anyone can call or interact with the function without needing special permissions or access rights.Public functions are usually part of smart contracts, which are self-executing contracts with the terms of the agreement directly written into code. Since these contracts run on a decentralized platform, anyone can review, audit, and use the public functions as they see fit.Examples of public functions include transferring tokens, querying balances, or executing certain actions tied to a smart contract. The transparency of public functions helps ensure accountability and trust, as all actions can be verified by anyone who interacts with the blockchain.Overall, public functions play a crucial role in enabling decentralized applications by allowing open participation and interaction among users on the network.
