Distributed System have no single authority and each node is connected to every other node while in Decentralized System each node is not connected to every other node as it also have no single authority. Then how Blockchain is a decentralized-distributed system?

Distributed systems mean that more than one computer is used to perfom a specific task. They can be centralised, like in cloud computing where users connect to a group of computers that are owned by a specific cloud provider, or descentralized like peer to peer systems like BitTorrent where files are shared between computers without the need of a centralized resource. Blockchain is also a form of peer to peer system.

  • So it will be a decentralized system. How it have both decentralization and distribution properties? – HAMMAD ALI Jan 26 '20 at 09:19
  • A decentralized system is a subset of a distributed system. If it has descentralization properties it must have distributed properties as well. – anegru Jan 26 '20 at 09:52
