Centralization
Centralization is when a single entity has control over a network or structure. This means that the central entity has the power to manage, control, and supervise the entire system. For example, a country's currency is managed by its central bank. This means that the central bank has the authority to regulate the supply of money, set interest rates, and control inflation.
Decentralization
Decentralization is the opposite of centralization. In a decentralized system, no single person or entity has control over the network or structure. Instead, the system is managed by a network of users who work together to maintain the system. This means that no one person or entity can make decisions on behalf of the entire network.
Decentralization in Blockchain
Blockchain is a decentralized system. This means that no single person or entity has control over the network. Instead, the network is maintained by a network of users who work together to validate transactions and maintain the integrity of the system. This is done through a process called consensus, where users agree on the validity of transactions and work together to maintain the system.
Centralization in Blockchain
While blockchain is a decentralized system, there are some instances where centralization can occur. For example, some blockchain networks have a central authority that controls the network. This can be seen in private blockchain networks, where a single entity has control over the network. However, this is not the case for public blockchain networks, which are truly decentralized.
