Types of blockchain in Supply Chain

When an enterprise formulates a blockchain solution for its supply chain requirements, the decision must be made as per the type of blockchain that will suit the project and team’s purpose. Therefore, before hiring a blockchain development company in Australia, it is essential to have a clear understanding of the types of blockchain structures available. 

Permissionless vs. Permissioned blockchains

All blockchain structures are characterised as permissioned, permission less, or both. Permissionless blockchains enable their users to pseudo-anonymously become the nodes of the network while posing no restrictions on their rights.

On the contrary, permissioned blockchains don’t let all nodes gain access to the network and also restrict their rights. In addition to this, all users know each other on a permissioned blockchain.

Permissionless blockchains are more secure than permissioned ones, as they tend to have more nodes to validate transactions. However, permissionless blockchains may also have long transaction processing times due to the number of nodes. Contrarily, permissioned blockchains are more efficient as access to the network is restricted. As they have fewer nodes, there is less processing time per transaction. 

Permissioned and permissionless blockchains can be further classified into four types. Although firms that provide blockchain app development services may offer all structures, it is essential to understand what will suit the purpose-

Public blockchains are permissionless. They are completely decentralised and allow any user to join the network. Apart from this, they allow all the nodes of the blockchain system to have equal rights to access the network, create and validate blocks of data. Bitcoin, Ethereum and Litecoin are a few known public blockchains. Enterprises can connect with any blockchain development company in Australia to develop a public blockchain. 

Private blockchains are also referred to as managed blockchains. They are permissioned blockchains and are controlled by a single organisation. In a private blockchain, the central authority determines who can become a node. This central authority also decides which nodes should be granted equal rights to perform functions. These blockchains are partly decentralised as access to their network is restricted. Some most popular private blockchains include Ripple, a business virtual currency exchange network and Hyperledger, an umbrella project of open-source blockchain applications.

A consortium blockchain is a permissioned blockchain that is governed by a group of organisations. As it is not managed by a single entity, consortium blockchains have more decentralisation than private ones, resulting in higher security. But, setting up a consortium blockchain can be a fraught process as it requires cooperation between a large number of organisations.

These blockchains are controlled by a single organisation, however, with a certain level of oversight performed by a public blockchain, which is required in certain transaction validations. One known example of a hybrid blockchain is the IBM Food trust that was developed to improve efficiency in the food supply chain.
