While we try to understand Blockchain better, it is very important to understand how its two major network types work and what advantages do they bring to our business. Each type has its own set of benefits which is why it is important to analyze them and use the best one for our business.
Before we get into how different Public and Private Blockchain, let us have a look at some of their similarities.
- Both are decentralized peer-peer networks and every participant involved in the transaction maintains a copy of the same.
- Through a protocol referred to as consensus, both networks maintain the replica of transactions and are in sync with each other. This means any change or addition made on the transaction information will be immediately reported to the other party.
- A certain level of security is maintained by both the networks
So, what is the difference?
The primary difference between the public and private blockchain networks is the participants who are allowed to be a part of the network and maintain the shared ledger.
Public Blockchain is completely open and anybody can join and be a part of the network. It has an incentivizing mechanism that encourages more and more people to participate in the network. Private Blockchain gives a little bit authority to the firm or organization that controls the network. Only a certain individuals can be a part of it who qualify a set of terms and condition and it’s the company that controls who can read access to their transactions. This brings a level of privacy in private networks which the public networks lack.
A major drawback of public blockchain networks is that it involves a good deal of computational power which is a necessity as the distributed ledger needs to be maintained on a large scale. The consensus process is also a little more intense and the whole process results in a little more costly affair than the private networks.
Public blockchain has low transactional speed owing to the huge pile of data that needs to be processed to complete the transaction. Private networks, however, initiate the transactions quickly, as the parties involved have an inbuilt trust, the network nodes are well connected, which is why the consensus happens a lot more quickly. This makes them an efficient system which a lot of traditional business and governance model are eying upon.
The immense potential and accelerated growth that blockchain has brought to the tech-world are highly remarkable. The added interest from a wide range of industries across various sectors is a stimulant in the entire process which makes us believe that Blockchain is indeed the technology of future.
