Methods and systems for implementing Blockchain-based verifiable claims for use with assets in a physical world, such as Internet-of-Things (IoT) devices, are described. Verifiable claims are integrated with Root of Trust (RoT) technology, in a manner that allows verifiable claims to be linked with physical assets and a “proof” of provisioning of decentralized identity to be established. A system integrates Blockchain and IoT technologies, including Blockchain IoT device with hardware RoT implemented thereon. A validation process leverages RoT of the device to establish a decentralized “proof” of RoT on the Blockchain, which can then be used as a verifiable claim for the device. The validation process can also use the “proof” of RoT to further validate data obtained from the Blockchain IoT device, and to validate business logic allowing context based control of any subsequent transactions. Further, the validation process achieves automation with respect to trustability.
