Datum can never be successful because all of their assumptions on which their reasoning is based are faulty.
How so? What assumptions do you question? The general idea seems to be viable imo.
The crypto-economics are wrong.
No-one wants a new database that only stores user data.
No-one wants to get paid to see advertisements.
well, I for one would use such an offer if the rewards were high enough. also, it is not only about watching ads.
Here let me go through it in detail, some of this is my opinion, some of it is easy to inter from facts.
http://www.ejinsight.com/20181113-datum-blockchain-business-won-t-rely-solely-on-token-economics/"decentralized data storage" - no-one cares about decentralized data storage, sure people want to store data but they don't care if its decentralized or not, that's not a deciding factor, its just a nice to have.
"trading platform" - for data, unlikely, many bigger players have tried this and are trying, they are well funded and a lot bigger. There is some data trading for AI in the crypto space.
"The reality is that one of the most popular decentralized applications (dApps) on the Ethereum network, CryptoKitties, has only a few hundred daily users." - yes no-one cares about Dapps. A simple fact to observe.
"However, the adoption of blockchain technology is lower than expected; " - not exactly, we are now entering into a period where only those things that are really used will survive, part of the normal tech cycle, Dapps are not important. There are many other blockchain technologies which are being adopted other than Dapps. Now is the right time for value investing in those things which will survive.
“I don’t see [the next wave of growth] happening at the moment. I would be surprised if anything really changes in this market by end of this year - there's plenty of growth, just not in dapps.
http://www.ejinsight.com/20181113-data-breaches-raise-public-awareness-of-risks-to-privacy-datum/"The user can choose to authorize individual merchants to send advertising messages to them, and will receive a token issued by Datum, named DAT, in return." - no no no, no-one will care. User's don't want to control this, this is time consuming to control for the user, for the individual merchant they won't have a large enough user base to advertise to. Those users who do use it are after the DAT coin and are scamming the system. There may be a small sub-set between scammers and normal people who might care but thats a small overlap of two larger sets of people. People are time poor and don't care - more people don't even use more than 5 apps on their phone from week to week, they definitely won't use the Datum app. People don't switch between 50 apps during their weekly life, they just go back to a few small ones which do what they want, ie, whatsapp, banking or whatever. Datum app won't fit into that sub-set of apps.
Its fundamentally unworkable as presented by Datum.
"We can’t get Facebook and Google to change the way they store their users’ data,” Haenni said. “What we are basically doing with Datum blockchain platform is building an infrastructure where developers can properly get access to your data, in a way that the user maintains trust and control over it.”" - Firstly no-one cares, on the one hand it sounds idealistic that developers can use this to get access to user data in a nice way where users will have control but without user data then developers don't want it and you can't get user data without developers, its a chicken and egg problem. You need one before the other. You either need data OR developers before you can get the other. Why? Because you can't have a build it and they will come attitude.
If you look at other businesses such as
https://www.swipecrypto.com/ you can see they have managed to get user data by partnering with a swipe screen, the swipe screen which already had user data can feed that data into their system, the chicken and egg problem is solved. That's called a razor and blades business model
https://en.wikipedia.org/wiki/Razor_and_blades_model - one thing is a cheap commodity, the other is the value.
The vast majority of what is said is sales stuff and doesn't matter its all fluff, and where a solution is presented its really unworkable.
There are solutions to this problem but that's not it, I'd love to see if they get it and see the solution because there is a real solution and its kind of obvious.
