Blockchain Technology Basics
Definition of Blockchain
At its core, blockchain is a distributed digital ledger that records transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network. This ensures transparency and security in the data handled by blockchain.
Key Components of Blockchain Technology
- Blocks and Transactions: Each block in a blockchain contains a list of transactions. Once a block is completed, it is linked to the previous block, forming a chain.
- Distributed Ledger: This technology involves a decentralized database that is managed by multiple participants across different locations.
- Cryptographic Hashing: Each block includes a unique code known as a cryptographic hash. This ensures data integrity and links the blocks together.
How Blockchain Works
- Transaction Processing: Transactions are recorded in a block, verified by nodes (computers in the network), and then added to the blockchain in a chronological order.
- Consensus Mechanisms: These are algorithms that ensure all nodes in a network agree on the validity of transactions. Examples include Proof of Work (PoW) and Proof of Stake (PoS).
- Decentralization: Unlike traditional databases controlled by a central authority, blockchains are decentralized, meaning no single entity has control, enhancing security and reducing the risk of fraud.
Top 10 Revolutionary Blockchain Technologies
