Blockchain is a decentralized and non-tamperable data ledger used to record transactions and asset ownership. Its main features include: Decentralization: distributed in a computer network and does not rely on a central authority. Immutable: Once a transaction is added, it cannot be changed unless approved by a majority of nodes. Transparency: All transactions are publicly visible and can be audited at any time. Security: Use encryption technology to protect data from tampering and hacking.

Blockchain: Decentralized Data Ledger

Blockchain is a decentralized and immutable data ledger used to record transactions and ownership of assets. It consists of a set of interconnected blocks, each of which contains a set of transaction records.

Main features of blockchain:

• Decentralization: Blockchain does not rely on any central authority or single point of failure, and transaction records are distributed across a computer network.
• Immutable: Once a transaction is added to the blockchain, it cannot be changed or deleted except by obtaining the consent of a majority of nodes in the network.
• Transparency: Every transaction on the blockchain is publicly visible and can be audited at any time.
• Security: Blockchain uses encryption technology to protect data from tampering and hacking.

Uses of Blockchain:

Blockchain was originally developed as the technology behind cryptocurrencies such as Bitcoin. However, it is now used in a wide range of applications, including:

• Finance: Payment processing, asset management, lending and supply chain finance.
• Supply Chain Management: Track goods, verify product origin and optimize logistics.
• Healthcare: Manage patient records, conduct drug trials and track medical supplies.
• Government: Electronic voting, land registration and identity verification.
