Blockchain technology is a decentralized and distributed ledger system that securely records and verifies transactions across a network of computers. Here are key aspects:


Blockchain operates on a peer-to-peer network, eliminating the need for a central authority. This decentralized nature enhances security and reduces the risk of a single point of failure.

Immutable Ledger

Once a block of data is added to the blockchain, it is cryptographically linked to the previous block, creating a chain of blocks. This linkage makes it extremely difficult to alter historical data, ensuring the immutability of records.

Cryptographic Security

Transactions on the blockchain are secured using cryptographic techniques. Each participant in the network has a private key to sign transactions, and a public key allows others to verify the transaction’s authenticity.

Consensus Mechanisms

Blockchain relies on consensus algorithms to agree on the state of the ledger. Common mechanisms include Proof of Work (used in Bitcoin) and Proof of Stake. Consensus ensures that all nodes in the network have a consistent view of the data.

Smart Contracts

These self-executing contracts with the terms of the agreement directly written into code automate and enforce contractual agreements. Smart contracts run on the blockchain, providing transparency and reducing the need for intermediaries.
