The blockchain is basically a distributed data storage system, where every recorded data secured by a cryptographic key is eternal and irreplaceable, so it tries to replace data that can be detected very easily. Blockchain is not limited to crypto currency transactions only. In the future, try the Blockchain as well as supporting the following smart solutions: Next, I will review a number of types of blockchain currently being developed and functions, here are the reviews:

1. Public type blockchain
This type of blockchain model is the most commonly used today because it was developed jointly without community space (block). Initially this was the agreement of a number of users or online forums. Every user can use or change the software. However, the user will not get the loss obtained from using the software. However, the blockchain model is very useful because it is easily accessed, approved and corrected at any time.
Fundamental weaknesses are only because a public (open) system will be a problem because many irresponsible parties will attack or approve this blockchain model. How to find bugs in the attack process and be more efficient in making blocks down. Users of the smart and many blockchain can certainly ward off the way because of the nature of the blockchain that isn't centralized.

2. Blockchain the type of consortium
It is different from the public type which is done jointly by a community. The blockchain consortium model was developed independently by leading companies in the blockchain field. They have finished preparing to continue the process.

Certainly with the support of reliable technicians and experts in their fields, surely the blockchain model is the most widely developed at this time. Many companies or even startups are developing the idea of ​​a blockchain type consortium. Because it discusses potential and certainly becomes a trend in the future.

3. Private type blockchain (Closed)
Finally, the type of blockchain that is protected is closed (private), namely those that do not publish the source code to the public and are considered as intellectual rights. Because of its private nature, it means that the blockchain network used is only intended for the company. The concept of the private blockchain is very suitable for state institutions that require security and confidentiality. Only those in this environment know and this model has been widely used in various state-owned institutions. Not Closed Will Continue to Grow Better.


And in my opinion that matches the type of Blockchain the type of consortium.
