What Is Blockchain?
Blockchain is a decentralized network that stores data in blocks chained together to form an immutable ledger.
The system operates on a trustless model where transactions are validated by nodes in the network.
Each block within the chain contains a batch of transactions that, once added, cannot be altered.
This feature enhances the security and transparency of the system.
The chaining process links these blocks sequentially, establishing a chronological record of transactions.
Data stored in the blockchain is distributed across multiple nodes, which makes it resilient to tampering or hacking attempts.
This decentralized structure ensures that no single entity can control the entire network, providing a level of autonomy and security that is unparalleled in traditional centralized systems.
How Does Blockchain Work?
Blockchain operates by recording transactions in blocks that undergo verification via a consensus mechanism, such as proof-of-work. Once a block receives validation, it becomes part of the chain, guaranteeing the integrity and immutability of cryptocurrency transactions.
The process initiates with a new transaction proposal within the network.
Miners then engage in a competition to solve intricate mathematical puzzles in order to validate these transactions.
This is where proof-of-work becomes crucial – miners must dedicate computational power to discover a solution, demonstrating their dedication and reinforcing network security.
Upon solving the puzzle, the freshly verified block is appended to the chain, establishing transparency and security.
Each block includes a distinct hash that connects it to the previous block, forming an unbroken sequence of authenticated transactions.
What Are Servers?
Servers are crucial centralized entities that are responsible for storing and managing data, serving as the foundation of network infrastructures.
