Blockchain is a system of distributed ledger technology that enables the secure and transparent exchange of digital information. It is an immutable, cryptographically-secured public record book that stores data in a decentralised fashion.


Blockchain Technology

Blockchain technology has the potential to revolutionise how we conduct our digital lives, from banking to contracts and asset management to voting systems. Blockchain technology is already being used to securely store and transfer digital assets such as cryptocurrencies. It has been described as “the next internet” because of its potential for transforming the way we conduct transactions, store data and interact with each other online.

At its core, blockchain is a system that allows users to record secure, immutable records, all transactions are broadcast and stored across multiple computers, allowing for greater security and trust than traditional methods of storing information. By using cryptography to encrypt data, blockchain ensures that all participants have access to the same information while preventing any single party from having full control over it. The potential applications of this technology are virtually limitless. From financial services to healthcare, blockchain technology can be used for a variety of purposes, such as securely transferring assets, verifying and validating transactions, establishing digital identities, and providing secure access to data and information.

Blockchain in the public sector

Blockchain also has implications for the public sector. Governments around the world are exploring ways to use blockchain technology to improve transparency and build trust in government transactions. In addition, blockchain can help reduce fraud, increase efficiency, and bring greater accountability to public processes. The key takeaway is that blockchain technology offers numerous benefits and applications that can be used in a variety of industries.

4-Key Pillar of Blockchain Technology:

One of the core features of blockchain technology is its decentralisation. Blockchains are distributed ledgers, meaning there is no single point of failure and no centralised server that could be hacked or corrupted. Transactions are added to a blockchain in batches, known as blocks, which are then linked back to previous blocks in chronological order. This means that all participants have a copy of the ledger and data stored on the blockchain is immutable, secure, and resistant to tampering.


One of the primary benefits of blockchain technology is immutability. Thanks to cryptography, information stored on a blockchain can’t be tampered with or modified without being detected. This feature makes it virtually impossible for hackers to change transactions and disrupt the system.


Another key benefit of the blockchain is its transparency. All transactions made using a blockchain are visible to all participants, which provides more trust and accountability than traditional systems. This allows for greater oversight and makes it easier to detect fraudulent activity or errors in the system.


Finally, blockchains offer enhanced security compared to other systems because they use cryptographic algorithms to secure transactions. This means that all data stored on the blockchain is protected by these algorithms and is virtually impossible for hackers to access or modify without being detected.
