Blockchain technology

Definition

Blockchain technology is a decentralized digital ledger system that securely records transactions across multiple computers, ensuring the integrity and transparency of data without the need for intermediaries. This innovation allows for increased efficiency, reduced fraud, and greater trust in various applications ranging from finance to supply chain management.

5 Must Know Facts For Your Next Test

1. Blockchain operates on a peer-to-peer network, meaning each participant has access to the entire database and its transaction history.
2. The technology is immutable, meaning once a transaction is recorded, it cannot be altered or deleted, providing a permanent audit trail.
3. Blockchain enhances security through cryptographic techniques, making it difficult for unauthorized users to manipulate data.
4. Smart contracts facilitate automated processes in various industries by executing transactions when specific conditions are met without requiring human intervention.
5. The adoption of blockchain technology in financial services has led to the emergence of decentralized finance (DeFi), offering users greater control over their assets.
