May i know how blockchain is used in mobile applications? In what way Yappadappado use blockchain in this project? What do they need to take care to to be hacked in applications by the way unless they are talking about crypto-wallet applications from their platform?

Your hunch is right elycoinz, according to Yappadappadoo's whitepaper:


Indicating that blockchain will execute abovementioned procedures including app reviews (which we know, most of the times, can be manipulated in many ways making the ratings unfair and unreliable).

And it was a good move that Yappadappadoo is taking the apps ratings and reviews in an immutable platform.

The case here would be dependent on the nature of the PWA i guess.  By nature, i meant to say purpose & design.

As rightfully pointed out by Shikaina, applications that does not depend on online contents and constant in-app updates, we can be rest assured that the PWA can work without any internet connection. Whilst PWAs that needs online contents and related updates to run would definitely require an internet connection.  Though on the latter scenario, Yappadappadoo is to deliver  a solution that will allow PWAs to still run even with a very woobly internet connection giving PWAs a good advantage.

Facebook is already PWA and still will be consuming a lot of memory, I think. When browsing facebook, if the connection suddenly got disconnected, you can still browse pre-loaded page and pre-loaded videos and I think there's a setting for that.

Here's an article I found regarding Facebook implementing PWA in their platform!

There's not much point in knowing since one won't really understand how it works unless you're into github and code stuff but in lighter terms, facebook started using manifest, manifest is a file, a json file like when you create a MEW wallet you may save a json file other than the private key.

correct me if I'm wrong or not, in my understanding yappadappadoo don't care if it is online or offline, just for what is important was that its

connected into blockchain technology, where Blockchain technology has quickly moved past the stage of being just a vehicle for Bitcoin

or for the Finance Sector. As a public, decentral, digital register, the Blockchain shows all transactions in an open and transparent form and is

radically changing the ways that supply meets demand across all platforms and industries.

Yes it has multi platform feature means no restrictions, but how can be possible that android phone and iOS will allow yappadappadoo application to operate on their phones and tablets since yappadappadoo is new and want to compete with them (Android & iOS)? Even if they ask permission to Android and Apple iOS i don't think that this two would agree...

Im just wonder if yappadappadoo store will make charge or pay from user that will transfer their application to another user, since both of them have particular blockchain ID that will record all the transactions from user to user (p2p)?
