Blockchain technology is a decentralized digital ledger system that records transactions across multiple computers in such a way that the registered transactions cannot be altered retroactively. This technology operates on a peer-to-peer network, where each participant, or node, has access to the entire database and its complete history. The integrity of the data is maintained through cryptographic hashing, which ensures that any attempt to alter a block of data would require changing all subsequent blocks, making it virtually impossible to tamper with the information without detection.
This characteristic of immutability is one of the key features that distinguishes blockchain from traditional databases. At its core, blockchain is built on a series of blocks that contain transaction data, a timestamp, and a cryptographic hash of the previous block. This chain of blocks forms a secure and transparent record of all transactions.
The consensus mechanism, which can vary from one blockchain to another, ensures that all participants agree on the validity of transactions before they are added to the chain. For instance, Bitcoin employs a proof-of-work mechanism, where miners solve complex mathematical problems to validate transactions and add them to the blockchain. This decentralized nature not only enhances security but also reduces the need for intermediaries, thereby streamlining processes and reducing costs.
