A blockchain is a decentralized, distributed ledger that records transactions across multiple computers in a secure and transparent manner. Each transaction is verified by network participants and added to a chain of blocks, creating a permanent and unchangeable record of all transactions. Blockchains are most commonly associated with cryptocurrencies like Bitcoin, but they have many other potential applications in industries such as finance, supply chain management, and healthcare.

A blockchain is a distributed database that is used to maintain a continuously growing list of records, called blocks. Each block contains a timestamp, a transaction record, and a reference to the previous block. Once a block is added to the chain, it cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
Key characteristics of a blockchain:
- Decentralized: A blockchain is not stored in a single location, but rather on a network of computers. This makes it very difficult to hack or tamper with.
- Immutable: Once data is added to a blockchain, it is very difficult to change or remove it. This is because each block contains a hash of the previous block, which means that any change to a block would require changing all subsequent blocks as well.
- Transparent: All transactions on a blockchain are public and can be viewed by anyone. This makes it a very transparent system.
- Secure: Blockchains are very secure because they use cryptography to protect data. This makes it very difficult for unauthorized users to access or tamper with data.
Benefits of using a blockchain:
- Increased security: Blockchains are very secure because they use cryptography to protect data. This makes it very difficult for unauthorized users to access or tamper with data.
- Reduced costs: Blockchains can reduce costs by eliminating the need for intermediaries. For example, a blockchain could be used to automate the process of clearing and settling payments, which would reduce the need for banks.
- Improved efficiency: Blockchains can improve efficiency by streamlining processes. For example, a blockchain could be used to track the movement of goods through a supply chain, which would reduce the need for manual paperwork.
- Increased transparency: Blockchains are very transparent because all transactions are public and can be viewed by anyone. This makes it a very transparent system.
