Although the block chain technology powering projects is the same, the target consumers of the various blockchain types can differ. Public blockchains emphasis on the public as end-users, on the other hand private blockchains are intended exclusively at invitation users and their networks.

Public Blockchain

Public blockchain is the first kind of block chain technology. Here, crypto-monetary technology, was invented and popularised. It eliminates the centralization disadvantages, including reduced safety and transparency. Instead of disclosing information across a peer-to- peer network, DLT doesn't save information in any place. It requires some way in which data authenticity can be verified. This method is a consensus algorithm in order to establish agreement on the present state of the leader by participants in the blockchain. Two common consensus methodologies are proof of work (PoW) and proof of involvement (PoS).
