What Is Blockchain Technology and How Does It Work?

What Is Blockchain Technology?

Blockchain technology is a decentralized digital ledger that records transactions across many computers in such a way that the registered transactions cannot be altered retroactively. This ensures the security and transparency of data.

Key Features of Blockchain

• Decentralization: Unlike traditional databases, blockchains are not controlled by a single entity.
• Immutability: Once a transaction is recorded, it cannot be changed.
• Transparency: All transactions are visible to all participants with access.

How Does Cryptocurrency Work?

Cryptocurrencies use blockchain technology to gain decentralization, transparency, and immutability. They work through a combination of cryptographic keys, distributed networks, and consensus mechanisms.

Mechanisms Behind Cryptocurrency

• Cryptographic Keys: Secure transactions between parties.
• Peer-to-Peer Networks: Transactions are made directly between users without intermediaries.
• Consensus Algorithms: Methods like Proof of Work (PoW) or Proof of Stake (PoS) validate transactions.
