Topic: Why not "COVID" vaccine passports on a blockchain ID - page 2. (Read 438 times)
Well, it is very logical, but as you are asking why, there will also be countries that question why use it and its effectiveness is worth it. First of what you're thinking about, I think this phase is all vaccinated, so it will take time to research and integrate it. So I think this has also been a lot of people thinking about it and I think it will be for the future when we have full technology and adoption, the application to any field in life will are all resolved.
People are always thinking and linking that things happening in the world can be resolved by means of putting blockchain in between as if it can resolve anything. Remember all things have their own limitations no matter what happen. There could be areas they are very useful and there are things that others can do it on their own. Now with the case of putting info on a blockchain ID whether yoy have got vaccinated or what, it is not already needed for there are documents and medical records since the lifting of the travel ban implemented as a requirement before you can be able to travel and such way is already enough and blockchain will not be already needed to tag along.
Its not that easy to migrate into another system and for sure, blockchain will take time which is unnecessary for a time like this. We know how good blockchain is, but I’m sure government knows also how to create a good system which is already happening in many countries like Japan, New Zealand, Vietnam and many more without even using blockchain technology, so again this is not the top priority as of the moment. 
I believe, people are just thinking of ways how to make the process easier and smoother. However, authorities are not yet ready to utilize blockchain technology because most of them have no idea where to start. So if in case it will be implemented, it would take time and resources to deliver this kind of project. And right now, people have no interest on this task as there are more pressing matters to attend to. But of course, once this technology is implemented, the life would be much easier. However, it takes time to accomplish this project.
I agree with you. The pandemic and related events require a quick and effective response from the state authorities, and the current situation is not conducive to experiments in this area. Let's be honest, that despite some successful experience of implementing blockchain in different areas of public administration, it is still worth recognizing that all this is an isolated case and it is much more convenient for the authorities to use the usual tools that have shown their efficiency in the pre-pandemic time.

This topic could be ended with a phrase about the laws and medical data of citizens.
Each country has its own requirements for medical information on vaccinations, so it makes no sense to use blockchain for these purposes.
I don't think it is the best idea to use blockchain in all infrastructures, including medicine.
Maybe that's true, but when it comes to data management blockchain could've served better. Even with the present vaccination records management it is good to have combined data, but this isn't shared on cross border travel. I don't know how it works, but one of my friend told me about an application in which it automatically reports if someone is not maintaining social distance as well as about rise in body temperature. If that is possible data management can be made precise eliminating unwanted quarantine. However it is the government to make the decision as said in the post.Each country has its own requirements for medical information on vaccinations, so it makes no sense to use blockchain for these purposes.

For standard data management, traditional databases are also quite suitable, especially since government organizations have much more experience in using traditional databases than databases built on blockchain technology 
By the way, I would not be surprised if some country really tries to use blockchain, but I do not think that this will be a mass phenomenon.

As far as I can remember, there are several projects who already did this (or at least claimed that they're working on blockchain-based COVID passports). ID2020 might be the latest one that I know, they're working with some DPoS blockchain project if I recall correctly.
Pretty sure they won't use Bitcoin or Ethereum network since the cost might be way too much.
It doesn't even need to be a big deal, as far as I remember there were even some small carribean type of nation that actually put all the national ID information on blockchain, since they are island nations even one big fire could destroy all files and yes they can put it on servers but servers could be compromised as well whereas blockchain is something that's all around the world p2p so it will probably not be destroyed ever, could it be hacked? That depends on the software that uses it, but it is at least safe there and can be reached anytime we want.Pretty sure they won't use Bitcoin or Ethereum network since the cost might be way too much.
Same could be used with vaccine passports and it could be on blockchain very easily, it wouldn't take more than 30 days to build something like that and spread it and put all the data in there, just one month. However governments probably didn't want to deal with that since it is a new technology, it is easy but it is new, so they went with the old one.
You know that databases can also be encrypted, right? You know that whoever can access the software creating the blockchain can also read/understand the info, so it's not a difference from the DB, right?
The companies that encrypt it can easily decrypt it to sell our data for profit, blockchain is the best in my opinion. I do not yet know much about how the blockchain will be, but to my best of knowledge, no personal data will be stored on the blockchain. For example, the cryptographic key will only be like transaction ID (although not transaction ID), which will only reveal if someone is vacinated or not, no other information stored/revealed other than that. No medical officials to store data on any database as it is against the total makeup of the distributed ledger. 
It is completely different. For example, if I have been vaccinated by a health official, I will be given the credential about it (and remain to me alone), and also be validated on the decentralized ledger which can be verified through a form that will be given me with a specific cryptographic key which will serves as prove. The form with the specific cryptographic key key will be used to verify if truly I am recorded on the blockchain as one of the people that has been vaccinated. If I want to manipulate in this case, before I can manipulate anything, I will have to make a deal with a health official that do vaccinate people to help me validate a form with a cryptographic key on blockchain. Without this, no way to manipulate, but not compared to physical documents that I can make the fake ones from anywhere which is a lot easier.
1. The ledger will clearly not be decentralized (who would store and mine that and for what incentive?!). That's why it's not better than an ordinary database (it's actually worse).
2. If needed the API that accesses the DB can give you whatever keys and proof they implement, from something basic to cryptographic keys too.
3. I was referring to crooked officials manipulating the data. Either a DB entry is altered or added, either a blockchain entry (unalterable) is added, somebody will get a fake "passport".
All in all, while blockchain is - in theory - not changeable (depends on implementation though, it can be done bad too), as long as somebody can add new records it's not really better than a DB. Also since it's not decentralized, also a hacker can do deeper change (double spend), but indeed, that's more difficult. And since it's cheap to just add a new record, it doesn't make sense to hassle.
So I don't see a real advantage of the (again, centralized) blockchain for this use case.
This is a way our credentials (data) can be safe, it will remain with us than on a third party database, only the form will be on blockchain which has no credential of us. Unlike physical credentials in which blockchain is not used, there must be a database for collecting our vaccination data report. And the positive thing about this is that, it is the method suggested to be used, which will help protect peoples data from third party, although, still at its earliest age.
You know that databases can also be encrypted, right? You know that whoever can access the software creating the blockchain can also read/understand the info, so it's not a difference from the DB, right?
it would be a safe, secured, difficult to tamper and widely available method of travelling and proving that an individual has had a vaccine. No borders, no language, no need to carry papers around. just you bio linked a a recognised signature and you are good to fly. Perhaps this looks too futuristic, but the technology is already there and could be a great testing ground.
Its can be one of the great utilization of blockchain technology, however it should be implemented throughout the world to work which maybe the issue because we can't expect to have such kind of fast adoption all over the world. They may choose to adopt only if developed countries started to utilize this kind of passports.

Government doesn't know much about blockchain system works that's why you can see that they are still using the old method, and its long research to make this thing happen and this is not the time for doing some test regarding on using it on vaccine passport, maybe on other important things if they really want to explore the wide use of blockchain ecosystem.

Because this will cut the black market and the black market will be very actual in some regions globally (including my own country).
People always want to have access 'to another way' which is blocked by the blockchain, especially for controversies like mass vaccination.
It can be a good idea, but as you said, it's too futuristic, and our governments are lazy as sloth, so why would they really care implementing such product and technology when they can just enjoy the luxury of their beautiful cars and houses?! I do however think that, the blockchain can be better used for other more useful purposes if it's used by government rather than proving someone have had covid, because there are lots of problems with higher priorities that can be solved using blockchain technology.

The world needs something like this while the vaccination is still ongoing, so we have a database of people who got vaccinated, this will not be the last virus or pandemic that we are going to encounter, and by having this we have something in place already, maybe fifty years from now we will encounter another new virus that will set up a new pandemic, we are in a modern era we should make something easy for the next generation.
Have you traveled to 3rd world countries yet? Most of the infrastructure there are ancient and these people hardly have electricity and water, so you will not be able to go to these countries, if that was one of the requirements.
Also processes like this can easily be defrauded .... because there are always "humans" behind the capturing of this data that has to go onto the Blockchain. (Some Vaccines will also have to be repeated over and over again... )

Because you would need a world database, because the governments have incompatible systems
Blockchain does not change anything here. You have to have global database (something like excel sheet) or global software to add records to blockchain and the duty to teach thousands of people how to use the new system etc.
global centralized database might be close to free. Adding records to blockchain is expensive.
because it can be tampered with...
What for? Who would want to manipulate the information about who is vaccinated and who not, except for units that do not want to be vaccinated, but these will not have access to a centralized database anyway.What blockchain change here? You will be able to add anything you want in there. You only would not be able to change anything.
And in the case of this blockchain application, you do not need to change anything in the blockchain to make it tampered, person resposible for adding records to add "mr xxx just received vaccine" while in fact he didn't.
Blockchain is expensive and should not be applied everywhere where it is possible.
"Why not "COVID" vaccine passports on a blockchain ID" - because centralized database - simple excell sheet with ID and yes/no annotation in second column is good enough in such case. What extra use case bring blockchain here?
Because you would need a world database, because the governments have incompatible systems, because it can be tampered with... I think you have not though this over.
