what is blockchain technology

Blockchain technology is a decentralized and distributed ledger system that enables secure and transparent record-keeping of transactions across a network of computers. It is the underlying technology behind cryptocurrencies like Bitcoin, but its applications extend beyond digital currencies. Here's a brief overview:

Components of Blockchain Technology:

1. Blocks: Information is stored in blocks, which contain a list of transactions.

2. Chain: Blocks are linked together in chronological order, forming a chain.

3. .

1. Decentralization: Unlike traditional centralized systems, blockchain operates on a decentralized network of computers (nodes).

2. Consensus Mechanism: Nodes in the network must agree on the validity of transactions through a consensus mechanism (e.g., proof-of-work, proof-of-stake).

3. Cryptography: Blockchain uses cryptographic techniques to secure transactions and control the creation of new units
