Blockchain for Education

With blockchain, we can imagine a world in which certificates are embedded in digital code and stored in transparent, shared databases, where they are protected from deletion, tampering, and revision. In this world, students from all around the world will own their digital identity and studies across multiple educational institutes, creating a single, immutable and verifiable curriculum. Certificates of attendance, completion of exams, and diplomas can be issued on the blockchain and be digitally signed. No more fake certifications, no more degree mills, no more “photoshopped” papers.
In the future, students may apply for further study, a job, immigration to another country. They may require to prove their level of study or knowledge of language to attend university, for example. Entities like recruiters, employers, government, universities, can verify the student’s credentials without relying on central authorities, in just minutes, and with no other intermediaries.


Blockchain for Energy

Blockchain is a decentralized ledger technology. When applied to the energy sector, it will enable people to trade energy among themselves. Just as Bitcoin allows the exchange of digital currency with its peer to peer platform, blockchain will enable a fundamental shift in the distribution of energy. This shift will stimulate more renewable energy projects as a whole, ultimately forwarding our transition from carbon emitting electricity generation. Tokenizing renewable energy allows wind, solar and hydro producers to seamlessly connect with investors, who are willing to pay upfront for the right to consume renewable energy.


Blockchain for Health

With blockchain, medical records and certifications have a digital record and signature that could be identified, validated, stored, and shared in an immutable way. Patients will own their digital identity and medical records across multiple health institutes, creating a single, unmodifiable and verifiable medical registry.
Entities like hospital, health regulation agencies, government, universities, can verify the practitioner’s credentials without relying on central authorities, in just minutes, and with no other intermediaries.
When a request for proof of existence of a certificate is issued by a government or health regulation agency, a transaction is initiated by the practitioner, the relevant information is encrypted in a new transaction block using the public key of the entity requesting visibility on the certificate, and only the requestor, and no-one else, can decrypt this information using their own private key.
