- 5. Do you need a Blockchain? If a traditional database meets your needs, you don’t need a Blockchain. If you don’t mind putting someone in charge of the database, you don’t need a Blockchain. If you trust all the participants that update the database and it’s not likely for the database to be attacked, than you also don’t need Blockchain. In all other cases, depending on the level of the data privacy and restricted access you may need private or public Blockchain.
- 6. The Need of an Ecosystem Don’t forget that blockchains are transactional databases. All other documents and images should be stored outside of the Blockchain. We require a distributed storage or trustful cloud and data lake. In Blockchain we store simple transactions: – just as an immutable index of the data – metadata mostly for ownership and access info – URL link to the cloud that has the data

- 10. A Blockchain-based Online Marketplace for Personal Health Data https://hit.foundation/ Health Information Traceability - HIT
- 11. Some identified issues in Healthcare Data format and structure is not unified. On time data sharing is not achieved. Healthcare data is in silos of many healthcare providers. Hardly possible to gather all history of one patient. Who owns the patient’s data?
- 12. Opportunities In healthcare tremendous amounts of data are generated by medical documentation, regulatory requirements, and patient care. Digitization in healthcare lead to a constant rise of data being gathered on the individual user or patient’s level. In a recent survey in Switzerland 43% of all people would be willing to give personal data to medical research, either for free or for a reduction of their health insurance premium. In France 99% of all internet user would share personal information if they received cash rewards in return.

- 14. HIT’s Vision and Mission Blockchain-based online marketplace for health data Empowering patients with full control over their health data
- 15. Value Proposition Allow individuals to store, trace data usage and participate in its monetization. Individuals are granting access to their data under a smart contract. Smart contracts set conditions of the data usage by information seekers such as market researchers, academic institutions or hospitals. The HIT token is used as an incentive and aligns the motivation of all network participants. HIT motivates individuals to digitize their health-related data and give the individual the opportunity to a) earn a token in exchange for data and b) redeem bonuses for the tokens earned.
- 16. The Marketplace The HIT-system is only the enabler of an ecosystem where individuals can monetize their personal-health data. Data seekers can access data in a much more efficient, hence faster and even cheaper way. Participants must be able to exchange their tokens not only for information but also for a so called bonus. A bonus can be everything from a medical video-consultation to a wellness offer or a reduction in the health insurance premium.
- 17. Token – Information Exchange
- 20. Token Distribution - A total of 1 billion HIT tokens (cap) will be issued - The number of tokens is justified by the potential number of users and the transaction volume in the healthcare market. - In the crowd-funding the token will be sold at €uro 0.10.

- 22. Benefits of Blockchain for certificates Relying on centralized authorities to verify the authenticity of a certificate can be a slow and complicated process. Accessing the Blockchain and verifying a certificate directly in the system, replaces institutions with a permanent infrastructure of trust. At the same time, the Blockchain empowers individuals to hold their own official records and share them with others. The Blockchain acts as a notary that can always attest to the authenticity of certificates.
- 23. Blockchain for SIMSA SIMSA – Swiss Internet Industry Association This educational certificates solution enables Simsa members to create, store, validate (sign), display and revoke educational certificates. Some challenges: Who can issue a certificate? Where are the certificates stored? Who can verify the certificate’s validity? How can the system be always accessible?
- 24. Storing the certificates All certificates are stored in a decentralized storage with a local copy at multiple issuers. A digital certificate is essentially a JSON file with all the necessary fields. Our smart contracts place the certificate as a transaction in the Blockchain and share it between all the members. All future modifications of the certificate are also new transactions in the Blockchain.
- 25. Verifying the certificates For every certificate, the system creates a unique ID as proof of existence. The owner of the certificate knows the ID and the URL to her certificate and can share it when needed. Using the public Blockchain verifier, everyone with the certificate’s ID can ask for verification. Then the system checks both the proof of existence and the revocation status of the certificate. If all is fine, the system visually displays the certificate and the signature.

- 27. Hyperledger and OpenBadges - We have decided to use Hyperledger as the best framework for building permissioned blockchains. - OpenBadges is an open standard for verifiable, portable digital badges with embedded metadata about skills and achievements. - It is a JSON defined extensible format for the specific needs of the issuer
