Introduction to Blockchain Technology
Definition and Key Features
Blockchain technology is a decentralized, distributed ledger that records transactions across multiple computers in such a way that the registered transactions cannot be altered retroactively. Each “block” in the blockchain contains a record of a transaction, and each block is linked to the previous one, forming a chain. Key features of blockchain technology include decentralization, immutability, security, transparency, and consensus-driven validation.
How Blockchain Works
Blockchain operates by allowing participants to verify transactions without the need for a centralized authority. Each participant in the blockchain network has a copy of the ledger, ensuring transparency and trust. Transactions are verified by consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS), making it difficult to alter any data once it’s recorded.
