The Sui network security predominantly relies on blockchain consensus mechanisms, typically employing Proof of Stake (PoS) consensus mechanisms. These consensus algorithms validate transactions, secure the network against fraudulent activities, and confirm the authenticity of data. SUI token holders have the option to delegate their tokens to validators, which in turn enhances the network's security and stability. Validators or miners contribute their computing power or stake tokens to verify transactions and uphold the blockchain’s integrity, ensuring network stability and decentralisation.
