Definition of Blockchain Technology

Blockchain technology is a decentralized and distributed digital ledger system that enables the secure and transparent recording of transactions across multiple computers or nodes. It is essentially a chain of blocks, where each block contains a set of transactions or data.

Blockchain’s decentralized nature makes it unique, where no single entity or central authority controls the entire network. Instead, all participants in the network maintain a copy of the blockchain and work together to validate and verify transactions through consensus mechanisms.

The data in a blockchain is stored chronologically and immeasurable, meaning that once a block is added to the chain, it cannot be altered or tampered with retroactively.

This immutability is achieved through cryptographic hashing and linking each block to the previous one, creating a continuous chain of blocks. The consensus mechanisms, such as proof-of-work or proof-of-stake, ensure that all participants agree on the validity of transactions and maintain the integrity of the blockchain.

Blockchain technology has gained significant attention due to its potential to provide transparency, security, and trust in various applications beyond cryptocurrencies, such as supply chain management, voting systems, smart contracts, and, as discussed in this article, digital identity management.
