The Core Concept of Blockchain Explained

Concept of Blockchain

As far as tech breakthroughs go, blockchain development was a real game-changer; a system whereby the data on the chain is interconnected and an open-ledger system is in place and when a data block is added. All stakeholders must consent, which is done automatically in the background and it is this that makes a blockchain secure.

Recording all transactions

A blockchain network records all transactions in a decentralised open ledger; the chain is made up a separate data blocks that are interlinked; one block is connected to the one preceding it and the one after it and this chain cannot be broken. The only way to change things is add more data blocks and all stakeholders must be in agreement for a new block to be added to the chain.

Key elements of blockchain

The core concepts include:

  • Distributed ledger technology – All network participants can access the decentralised ledger and an immutable record of all transactions, while transactions are recorded only once, which eliminates duplication. To learn more, contact a leading Australian blockchain agency and the developers can demonstrate the system.
  • Immutable records – It is impossible to tamper with data once it has been accepted onto the blockchain; the only way to make changes is to add blocks to the chain. In the event an error is made, another block is added to amend the data and both blocks are visible.
  • Smart contracts – In order to speed up transactions, a specific set of transaction rules are visible on the network; smart contracts run automatically at very high speed. The precise conditions need to be met before a transaction can be accepted, which prevents unauthorised data amendments.

A blockchain can be used on tangible and non-tangible assets, such as intellectual property and due to the fact that the chain cannot be broken, only added to, it is 100% secure. If you are a gadget lover, check out the latest wireless headphones.

Public blockchain networks

Bitcoin is a good example of a public blockchain; anyone can join, all you have to do is download the Bitcoin wallet software, buy some Bitcoin and you are added to the participant list. There is a high usage of computing power with a global public blockchain, and security might be an issue.

Private blockchain networks

Corporations and companies create private blockchain networks, which are decentralised much like public networks, yet they are restricted to authorised personnel. A private blockchain is typically run behind a corporate network and can be ‘hosted on premises’.

Permissioned blockchain networks

Businesses typically set up a private permissioned blockchain network, which restricts those who can make transactions; it should be noted that a public blockchain can be permissioned.

Hackers certainly don’t like blockchain, as they have not been able to find a way to penetrate a blockchain; if you want a secure network, blockchain is the obvious solution and a Google search will help you find a leading Australian blockchain developer who has all the answers.
