KSI is a blockchain technology designed in Estonia and used globally to ensure networks, systems, and data are free of compromise, all while retaining 100% data privacy.
A blockchain is a distributed public ledger – a database with a set of pre-defined rules for how the ledger is appended by the distributed consensus of the participants in the system. Due to its widely witnessed property, blockchain technology makes it also impossible to change the data already on the blockchain.
With KSI Blockchain deployed in Estonian government networks, history cannot be rewritten by anybody and the authenticity of the electronic data can be mathematically proven. It means that nobody – neither hackers, nor system administrators, nor even the government itself – can manipulate the data and get away with it.
