Your online presence and interactions with companies in the real world that digitize your information to create a digital identity, and not necessarily you have in your control. Today, your personal data  have been recorded and stored without know to how it will be used in the future. Instead, it’s controlled by the institutions with which you interact. Blockchain technology for decentralized digital identities is making the way for an important paradigm shift centered around control of your digital identity. Now you can be in control of your personal data, who has access to what parts of it, and under what conditions. You may even get paid when your personal data is used.

The rights to physical assets or even personal identifiable data can also be represented digitally as tokens on blockchain networks. To address the challenges and risks associated with an individual or entity having total control over their digital assets, a secure, user-friendly interface with the means to transact and store those digital assets is fundamental in the development of applications and systems that interact with  solutions based on blockchain. Being able to securely and immutably connect physical assets to their digital asset counterpart leads us to interesting challenges where new business scenarios come to life.

The value of public blockchain networks is limited if we cannot easily access their data and interact with them securely. It is particularly important that the devices or software applications have the capability to interact directly with a blockchain network, without reliance on intermediaries. By connecting smart devices to a blockchain, from smartphones and computers to internet-enabled cars, advanced manufacturing machines, and security systems, we can facilitate marketplaces, payment services, or a sharing economy for the Internet of Things.
