No, centralized databases proved itself untrustful because the concept of being centralized holds the handiest and best supply of consider, and if it gets compromised (and it's going to, 0day the use of viruses will seem periodically) there is probably information loss/publicity, diverse from non-zero to one hundred% (assuming there are backups made, and stage at which data is encrypted).
Blockchain can dispose of this trouble, because it offers extreme degree of trustfulness to database cutting-edge u . S ., due to more than one consider nodes over the network which one after the other signal trustful transactions.
However, your point is valid, due to the fact there are more than one nodes which preserve same information country and all transactions being publicly to be had, the privateness is to be concerned approximately. There are tactics to make nodes do more steps on assuring transaction stays non-public and does now not divulgea.
