Blockchain is a digital ledger technology that allows data to be stored in a secure, decentralized, and transparent manner. It was originally developed as the underlying technology for the cryptocurrency Bitcoin, but it has since been adapted for a wide range of applications.
At its core, a blockchain is a distributed database that is managed by a network of computers. Each computer in the network, or node, maintains a copy of the database and participates in the process of verifying and recording transactions.
When a new transaction is initiated, it is broadcast to the network of nodes. Each node then independently verifies the transaction using a set of predefined rules. Once the transaction is verified, it is added to a block of transactions, which is then added to the existing chain of blocks. Each block contains a unique cryptographic hash that links it to the previous block, creating an unbreakable chain of blocks, or blockchain.
Because each block in the chain contains a unique cryptographic hash that is based on the previous block, it is virtually impossible to alter the contents of the blockchain without being detected. This makes blockchain technology highly secure and resistant to fraud.
In addition to being secure, blockchain technology is also transparent and decentralized. Because each node in the network maintains a copy of the blockchain, there is no central authority that controls the data. This makes blockchain technology ideal for applications where transparency and decentralization are important, such as supply chain management, voting systems, and financial transactions.
Blockchain technology is an advanced database mechanism that allows transparent information sharing within a business network. A blockchain database stores data in blocks that are linked together in a chain.
