BLOCKCHAIN: HYPE vs REAL Applications – Episode #3 of our History of the Blockchain


The blockchain is only a fledgling
technology, today in 2019! And as for the internet 30 years ago, we are in an initial phase of infancy. Beyond the buzz and the media hype,
there are in fact currently only very few applications of the blockchain outside the financial field. Most of the alleged applications are for the moment only basic decentralized databases which are backed by a very traditional security process. However, we can mention some very promising areas under development, which really exploit to their full potential the specificities of blockchain technology. The first area that interests me most is Traceability in the supply chain. The blockchain would at any time allow you to know that
a cooked dish served in a community comes from a referenced distributor, who bought it at a referenced factory, who made it from a referenced meat, bought at a referenced slaughterhouse, from an animal coming from a referenced farm. The manufacturing chain of an agricultural meal, medication, or industrial product, could thus be audited at any time,
and contaminated batches could immediately be identified without
possible falsification. For example, India’s biggest conglomerate,
Reliance Industries, is working on its “Jiocoin” project, which is a blockchain-based logistics platform for managing its entire supply and production chain. A second area of very promising application is the field of Medical Records.
The blockchain technology would make it possible to date and archive in a secure and tamper-proof manner all the visits of a patient to his doctor
and to any other specialist, as well as his prescriptions of drugs.
For the delivery of medication, the patient could give the pharmacist
a partial decryption key that would allow him to read his prescriptions
and deliver the drugs. Due to medical privacy, the pharmacist will
however not have access to the diagnosis from the doctor.
As for the emergency services of the hospitals and the ER services, they would have a complete reading key allowing them to be able to immediately access
the whole medical file of a casualty, thus understanding its antecedents and current medications.
