# Blockchain's Role

Blockchain technology ensures that all driving data and recommendations provided by the AI are stored in a decentralized and immutable ledger. This guarantees that user data is transparent, resistant to tampering, and trustworthy. Moreover, the blockchain-backed system ensures that rewards, based on driving habits and CO2 emission reductions, are automatically and transparently distributed to users through smart contracts.
