China, the country where the Covid-19 virus originated from, used many technological breakthroughs to combat the Covid-19 outbreak and help speed up the recovery of its industries:

• Blockchain, to check travel documents and gather information;
• Big Data, crucial for gathering important data;
• 5G, which connects everyone in a network at high speed;
• AI, allowing for unmanned production.

Combining these technological breakthroughs, China was able to more efficiently fight the spread of the virus thanks to:

• much faster virus diagnosis;
• better prevention;
• faster treatment;
• operating unmanned medical care production facilities;
• online education for children in lock-down;
• travel documents checking;
• work from home;

One not to forget property of blockchain is that it isn't physically transmittable: in other words: when comparing cryptocurrencies with traditional fiat money, it can not spread disease. Fiat currencies are a haven for bacteria, microbes from mouths, DNA from pets and viruses. Every time we spend fiat during a lock-down, we help the virus spread its wings and allow it to jump from one person to another.

Cryptocurrencies would also be very easy in a relief program when money needs to be sent to many thousands of temporarily unemployed people, which is the case in the USA today. It can help today, but also after natural disaster relief programs.

The world will learn a lot from this outbreak and several industries will adopt new guidelines to avoid the impact of future viruses that will are unavoidably coming. Viruses are around us, all the time, this particular virus is yet 1000 times more efficient in spreading and contaminating surfaces and ultimately finding a new host.

The world now witnesses the damage that a virus can do, if a population's government isn't prepared to layout social distancing measures and doesn't have a stockpile of necessary equipment for healthcare workers to save people's lives. The WHO will need to address the fact that China didn't inform them soon enough about their problems with a new coronavirus. This lack of global transparency has led to a production shortage of important medical products like ventilators and personal protective equipment because industries simply didn't get that important information and once they got it they couldn't deliver fast enough to make a big difference.

Countries will now need to create national emergency stockpiles, where they collect a number of crucial items that can help during a pandemic and other events.

Conclusion:

Blockchain is not the magical solution to all our problems, but the technology can help us in our efforts to create a safer world in which we can respond to an outbreak more efficiently. Imagine how China can use its databases to check who people had close contact with, to find the people they need to isolate. Unimaginable in western liberal democracies, blockchain has yet other important benefits that can assist us.
