Understanding Blockchain Technology
Definition and Principles
Blockchain is a distributed ledger technology that records transactions across multiple computers in a way that ensures the security and transparency of data. Each transaction or “block” is linked to the previous one, forming a “chain” of blocks. Key principles of blockchain include:
- Decentralization: Unlike traditional databases controlled by a central authority, a blockchain is maintained by a network of nodes (computers) that collectively validate and record transactions. This decentralization reduces the risk of a single point of failure and enhances the system’s resilience.
- Immutability: Once a block is added to the blockchain, it is virtually impossible to alter or delete it. This immutability ensures that the transaction history is permanent and tamper-proof, providing a reliable record of all activities.
- Consensus Mechanisms: Blockchain networks use consensus algorithms to agree on the validity of transactions. Common mechanisms include Proof of Work (PoW) and Proof of Stake (PoS), which ensure that all participants in the network agree on the state of the ledger.
