Validator nodes are pivotal elements within Jumbo Blockchain's Proof of Nexus (PoN) consensus mechanism, instrumental in the validation of transactions and the proposal of new blocks for incorporation into the blockchain. These nodes undertake the critical responsibility of ensuring transaction adherence to network regulations, actively participating in the consensus mechanism, and upholding network integrity. Validator nodes are rewarded for their contributions with transaction fees or block rewards, bolstering network security and decentralization. PoN blockchain network employs a system of periodic selection and rotation of validator nodes to prevent centralization and foster inclusivity and diversity.
