How Does Blockchain Technology Work?
What is blockchain technology and how does it work? Blockchain operates through a chain of blocks, each containing a list of transactions. These blocks are linked using cryptographic hashes, ensuring security and data integrity.
Step-by-Step Explanation of Blockchain Process
- Transaction Initiation: A user requests a transaction, which includes a digital signature for authentication.
- Verification: The transaction is broadcast to the network and validated by nodes (miners or validators) using cryptographic algorithms.
- Block Creation: Verified transactions are grouped into a block and timestamped.
- Consensus Mechanism: The block is validated through consensus mechanisms like PoW or PoS.
- Block Addition: The validated block is appended to the blockchain, linking it to the previous block via a cryptographic hash.
- Finalization: The transaction is confirmed and permanently recorded, preventing any modifications.
Consensus Mechanisms Explained
- Proof of Work (PoW): Used in Bitcoin; requires solving complex mathematical puzzles, consuming significant computational power.
- Proof of Stake (PoS): Used in Ethereum 2.0; validators are chosen based on the amount of cryptocurrency they hold and stake.
- Delegated Proof of Stake (DPoS): A more energy-efficient alternative where elected delegates validate transactions.
- Byzantine Fault Tolerance (BFT): Used in Hyperledger; ensures network consensus even with some malicious nodes.
Types of Blockchain Networks
Blockchain networks vary based on accessibility, security, and governance. The four primary types include:
Public Blockchain
- Fully decentralized and open to everyone (e.g., Bitcoin, Ethereum).
- Operates on a consensus mechanism like PoW or PoS.
- High transparency and security but lower scalability.
Private Blockchain
- Restricted access; used by enterprises (e.g., Hyperledger Fabric).
- Centralized governance with permissioned users.
- Faster transaction speeds but reduced decentralization.
Consortium Blockchain
- Governed by multiple organizations, ensuring partial decentralization.
- Used in finance, banking, and supply chain industries.
- Higher efficiency with controlled access.
Hybrid Blockchain
- Combines public and private blockchain benefits.
- Allows selective transparency and data sharing.
