For security we have secure elements on the hardware devices which will provide digital signatures for data validation. The device ids, in the form of public keys, will be on a blockchain for anyone to validate the data signatures. We also have device disconnect alerts in-case someone disconnects the device from the car. We have collaborated with multiple hardware partners and will have a vendor onboarding process wherein we will bring in more and more hardware players into the ecosystem. On the blockchain we are using proxies along with pausable function modifiers for security and upgradability of smart contracts. We will also be keeping larger pieces of data, like raw trip data, off-chain to make the contracts more gas efficient. --- # Agent Instructions This documentation is published with GitBook.
