Alien leverages the core characteristic of blockchain technologyβimmutabilityβto implement on-chain encryption of data, significantly enhancing the security of data during storage and transmission. Within this security framework, once data is encrypted and put on the chain, it cannot be altered or deleted, ensuring data integrity and resistance to tampering. Alien's on-chain encryption capabilities go beyond simple data protection, combining with smart contract technology to automate the execution of data processing and access rules.
