While there’s nothing inherently wrong with the article, I feel like the pros are very misleading. Every single point brought up in favor of blockchain would also apply to any other type of distributed database.
The section on trust does not clarify why a blockchain would be needed, any distributed system would have logging capabilities to know which entity updated/added/removed what data point and when. There’s no justification presented for needing something capable of handling false transactions a normal distributed database couldn’t handle.
Efficiency? Again any distributed database would have those same capabilities in tracking. If anything, running a blockchain is less efficient due to scaling issues mentioned later on.
Transparency? Again any distributed database can have this logging capability as mentioned above
There is nothing in this article that specifically explains to me why blockchain is the solution, this is just pros for a generic distributed database
