Why is Blockchain the Eye of Crypto Money?

The large distributed novel system (Blockchain) was first introduced in 2008 by a pseudonym Satoshi Nakamoto in a proposal titled, "Bitcoin: A Peer-to-Peer Electronic Cash System".

In the proposal, the title Blockchain is still not mentioned, but the basic concept underlines Bitcoin as an alternative electronic payment through peer to peer verification.

Bitcoin offers easy transactions between sellers and buyers anywhere and anytime, without the need for authorization from institutional parties (clearing agents, banks, etc.)

This alternative online payment proposal is indeed interesting, because it is able to cut fees and the long bureaucracy of traditional online payments. But what is actually more revolutionary is how the Bitcoin system (with Blockchain support) is able to authorize the transfer of ownership of Digital objects from one party to another without the mediator and the impact of double-spending.

When before Blockchain innovations are encountered, Digital objects (for example, file, music or film information) can easily be duplicated, so that anyone who has an original copy can spread duplication to others indefinitely.

Well, double-spending is a phenomenon where one tries to transfer something Digital object to another party but the Digital object has been duplicated more than once.

Certainly because of this weakness, the Digital object is out of value.

Alternatively, Digital object transactions must be verified by intermediaries or third parties such as clearing agents (banks) or centralized servers to check authentication in their network. New problems arise again from dependence on these third parties, are trust-gap and attack-vulnerability.

The assumption is that third-party service users are forced to have to trust-gap third parties even though their main server is something when it can be hacked by irresponsible parties (attack vulnerability).
