A whitelisted node is a type of participant in a blockchain network that has been granted special permissions. This designation allows the node to perform certain functions that other nodes may not be able to do, such as validating transactions or creating new blocks.To be whitelisted, a node typically undergoes a vetting process. This can involve meeting specific criteria outlined by the network’s governance model, such as demonstrating trustworthiness, adhering to certain regulations, or maintaining a certain level of performance. Whitelisted nodes play a crucial role in maintaining the security and integrity of the network. By limiting the ability to validate or create blocks to trusted nodes, the network can reduce the risk of malicious activity, like double spending or fraudulent transactions. The concept is often used in private or permissioned blockchains where control over who can participate is essential for operational efficiency and security.
