What makes a blockchain-type of DB more secure than the others?
...
The blockchain was designed for a specific purpose.
If you can determine the purpose, then you can answer your own question.
Comparing the blockchain to a type of database, is really the most basic layer of it.
See Wikipedia for their input:
https://en.wikipedia.org/wiki/BlockchainI was said I could not base a serious research on Wikipedia. In my opinion, Wikipedia is nice and I have personally experienced how much effort/validation it takes to publish any text there, but I cannot help if the scientific society has doubts about it.
Could you suggest any professional article that compares the blockchain type of DB to the others?
Also, the question remains. How probably is it that there will be a more secure design than blockchain soon?
