COVID-19 has had a devastating global impact. Travel and tourism industries have been particularly crippled by the virus, with no near term end in sight. Also concerning is the understanding that this will probably not be the last time that a global pandemic will affect all aspects of life for the world’s population. There is, or there should be, an internalization that if the world is to remain open, it needs to be prepared. Some kind of systematic solution is needed that will assist the global community to live through a pandemic without a mass closing of borders.
Many countries are struggling to adapt, and even those that have succeeded in curtailing the disease have solutions that are far from optimal. Testing each individual upon arrival is labor-intensive and expensive. On the other hand, allowing people in without a test, relying only on “green countries/zones”, or accepting test results that are practically impossible to validate might incentivize adverse selection and have severe consequences in further spreading the disease.
We need a solution for the future, and the key to that solution is blockchain.
Blockchain is most effective when multiple parties need to work together, but do not want one party to control the database; instead, they want shared control and visibility, combined with immutability. So the use case of a global (in our case COVID, but in the future for all other pandemics) passport that would connect to each country’s network of verified medical labs and confirm either immunity or test results, is almost self-explanatory in it’s blockchain use case. This solution would allow multiple local governments, whether states, regions, or cantons, to coordinate amongst themselves with or without the support of a federal or central government. In many instances, local coordination can be far more efficient, productive and effective than waiting for a central government to get its act together. By way of example, in the US, multiple governors could coordinate their health efforts or travel restrictions in order to control flow into their jurisdictions. Similarly, in the EU, member states could use the system to control or stem the flow of visitors into “green zones''. Another benefit is that medical institutions could easily share data on testing methodologies, best practices or any other type of information as part of the global effort to fight the pandemic.
Of course, a system like this would need to address important challenges. For one, user privacy is paramount. Individuals will need to share test results while minimizing access to all other personal data among the parties involved. Second, test authenticity will need to be proved. And finally, based on the above, destination countries will need an instrument that will allow them to set a coherent policy for allowing visitors to cross their borders.
Orbs has been discussing this vision for utilization in an EU member country. We proposed a platform that will consist of two permissionless blockchain databases that are constantly interacting with each other and a mobile app:
Upon reaching the passport control post, the individual will present her digitally signed test results over the app. The results will be verified online to make sure that the results are authentic (properly notarized on the Certificate Registry), reliable (conducted by a reliable Tester), and valid (a combination of the previous two along with the individual’s ID).
Blockchain provides the following benefits for:
Naturally, both registries are constantly being updated. In the Trust Registry new testers apply for registration or existing testers are being endorsed (or revoked). In the Certificate Registry, Tester status is being updated as Testers notarize new test results. Cities, states, regions or countries using this system will have a seamless, transparent and continuously updated database that will allow them to keep their borders open for those who are verified as disease-free, and thus their economy functioning - in a healthier manner.
It is time for a wake-up call and for global coordination and preparation. SARS, MERS, Ebola provided past warnings of what was to come - but COVID-19 took us all to another level. What is to say that the next global pandemic will not be even worse? Given the increasing importance of business travel and tourism to the global economy, we can not remain unprepared. On a technological level, it is time to up the universal game and work together to make sure that we are not torn apart.
