Understanding Blockchain Technology

Within the rapidly evolving digital landscape, understanding blockchain technology is imperative for harnessing its potential for web security and trust.

Defining Blockchain and Its Architecture

A blockchain is often described as a decentralised ledger that records transactions across many computers. This means that no single entity has control, ensuring security and integrity. Fundamentally, the architecture of a blockchain is such that it’s immutable; once data has been recorded, it cannot be altered without changing all subsequent blocks and gaining network consensus. This distributed database is structured into blocks linked and secured using cryptography, creating a tamper-resistant chain.

Types of Blockchains: Private, Public, and Consortium

Blockchains come in several types, primarily public, private, and consortium. Public blockchains like Bitcoin are open to anyone and use incentives to maintain the integrity of the network. Private blockchains restrict access and are controlled by a single organisation, making them more centralised. Consortium blockchains straddle the line between the two, with a group of organisations controlling the network, often used for business collaborations.

How Transactions Are Recorded on a Blockchain

On a blockchain, a transaction undergoes verification by network nodes through a process called consensus. Upon verification, the transaction is grouped into a block with others. Each block contains a unique code, called a hash, and the hash of the previous block, creating the chain. This process ensures each block is cryptographically linked to its predecessor, enhancing the decentralised trust of the network.

“We’ve witnessed how blockchain’s robust security mechanisms can help prevent fraud and unauthorised activity, making it a significant advancement in digital transactions,” says Ciaran Connolly, ProfileTree Founder.
