Blockchain technology is a decentralized and distributed ledger system that records transactions across multiple computers in a way that ensures security, transparency, and immutability. Its core components include:
- Blocks: Data containers that store information about transactions.
- Transactions: Records of actions, such as transferring assets or data.
- Decentralization: No central authority or intermediary is required; participants maintain the network collectively.
- Consensus Mechanisms: Protocols that validate and agree on transactions.
- Cryptographic Hashing: Algorithms that secure data within blocks.
