Understanding Blockchain Technology
Blockchain technology is a decentralised digital ledger that records transactions across multiple computers. It comes in two types: public and private blockchains, each with its own unique security features.
Definition of Blockchain
Blockchain is a cutting-edge technology that works like a digital ledger. Picture it as a book where you can write down transactions or agreements, but once you’ve written something, nobody can erase or alter it.
This means all the information is secure and transparent for everyone involved. Instead of being stored in one single place, this ledger spreads across a network of computers. Each part of this network has to agree on any new entry before it’s added to the chain, making the process decentralised and tough for cybercriminals to attack.
This tech forms the backbone for most digital currencies, but its uses reach far beyond just cryptocurrencies. Sectors such as healthcare, finance and even government services are looking at blockchain as a way to keep data safe from hackers and other online threats.
It offers an innovative approach to safeguarding sensitive information by securing data with sophisticated cryptography – basically converting the data into virtually unbreakable codes which only authorised users can decrypt.
Its robust security features make blockchain not just revolutionary in managing digital currency exchanges but also key in protecting our online activities from cyber-attacks and ensuring privacy protection in our increasingly interconnected world.
Types of Blockchains (Public and Private)
Following the definition of blockchain, it’s important to understand the different types of blockchains, namely public and private. These variations cater to different needs and offer distinct features catering to various applications and industries.
- Public Blockchains: These are open networks where anyone can join, participate, or transact. They are decentralised and provide transparency and security by allowing anyone to view the entire transaction history.
- Private Blockchains: In contrast, private blockchains operate within a specific network or organisation, limiting access to verified participants. They offer more control over who can participate in the network and who can view the transaction history.
- Permissioned Blockchains: This type of blockchain combines aspects of both public and private blockchains by giving certain individuals or entities permission to participate in the network while still maintaining a level of decentralisation.
- Consortium/ Federated Blockchains: These are semi-decentralised blockchains where a group of organisations come together and control the consensus process, making them suitable for industry collaborations.
- Hybrid Blockchains: As the name suggests, these blockchains combine elements of both public and private blockchains to leverage the strengths of each type while minimising their weaknesses.
- Sidechain/Childchain: These are additional blockchains that run parallel to the main blockchain, offering opportunities for scalability without compromising on security or data integrity.
