Private and Public Blockchain
Depending on the needs of an organisation, they can choose from Private and Public Blockchain networks. The difference in these is, for Public Blockchain network computers connected to the public internet and easy accessibility are used to validate transactions and bundle these public computers into blocks to add to the ledger. Any computer or device connected to the internet can easily and actively join the party. Private Blockchain, on the other hand, allows only the known organization to join. Together these private organizations comprise a member only “Business network”.
It is quite obvious from the nodes comprising either the Public or Private network that which will have a better security feature and which will be more prone to be tampered or hacked. A public network, considering how it is made up, may not be the right choice for an enterprise. Whereas for an open library, it may be the best-suited option. Considering an organization, the better option would be always a private network with access credentials to every individual so as they know exactly who are they dealing with.
