Op, you should understand that there are different types of blockchain networks and each operates using different features, not all are very secure, or public(transparent), or decentralized.

there are still 3 problems: scalability, security and decentralization.

How does decentralization become an issue with the blockchain when it is the main feature of the technology?
Security is also not an issue depending on the algorithm which that network uses, some are more secure than others, scalability also varies with different networks abd different transaction destinations.
