decentralised system in systems theory is a system in which lower level components operate on local information to accomplish global goals.
centralised system is one in which a central controller exercises control over the lower-level components of the system directly or through the use of a power hierarchy (such as instructing a middle level component to instruct a lower level component). The complex behaviour exhibited by this system is thus the result of the central controller’s “control” over lower level components in the system, including the active supervision of the lower level components. A decentralised system, on the other hand, is one in which complex behaviour emerges through the work of lower level components operating on local information, not the instructions of any commanding influence. This form of control is known as distributed control, or control in which each component of the system is equally responsible for contributing to the global, complex behaviour by acting on local information in the appropriate manner
decentralized system is an interconnected information system where no single entity is the sole authority
decentralized system generally has multiple authoritative nodes, each of which serves a subset of the total end users. In a distributed system, however, there are no end users, because every node on the network communicates with every other to behave as a single unit.
decentralization refers to the transfer of control and decision-making from a centralized entity (individual, organization, or group thereof) to a distributed network
decentralized system that operates on the blockchain is controlled by no single authority, nor is it backed by any centralized government or nation-state
control is distributed fairly to anyone that wants to use the system
Three types of Decentralization
- Architectural (de)centralization
- how many physical computers is a system made up of?
- Political (de)centralization
- how many individuals or organizations ultimately control the computers that the system is made up of?
- Logical (de)centralization
- does the interface and data structures that the system presents and maintains look more like a single monolithic object
why is decentralization useful in the first place? There are generally several arguments raised:
- Fault tolerance :: decentralized systems are less likely to fail accidentally because they rely on many separate components that are not likely.
- Attack resistance :: decentralized systems are more expensive to attack and destroy or manipulate because they lack sensitive central points that can be attacked at much lower cost than the economic size of the surrounding system.
- Collusion resistance :: it is much harder for participants in decentralized systems to collude to act in ways that benefit them at the expense of other participants, whereas the leaderships of corporations and governments collude in ways that benefit themselves but harm less well-coordinated citizens, customers, employees and the general public all the time.
property of a system in which nodes or actors work in concert in a distributed fashion to achieve a common goal.
Decentralized organizations are those that do not rely on a single center of authority to enforce the rules and maintain operation.
