Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the network, forming a peer-to-peer network of nodes.
Decentralization or decentralisation is the process by which the activities of an organization, particularly those regarding planning and decision-making, are distributed or delegated away from a central, authoritative location or group and given to smaller factions within it.

Grokster Ltd. was a privately owned software company based in Nevis, West Indies that created the Grokster peer-to-peer file-sharing client in 2001 that used the FastTrack protocol. Grokster Ltd. was rendered extinct in late 2005 by the United States Supreme Court's decision in MGM Studios, Inc. v. Grokster, Ltd. The court ruled against Grokster's peer-to-peer file sharing program for computers running the Microsoft Windows operating system, effectively forcing the company to cease operations.
In computer networks, download means to receive data from a remote system, typically a server such as a web server, an FTP server, an email server, or other similar systems. This contrasts with uploading, where data is sent to a remote server.
An organizational structure defines how activities such as task allocation, coordination, and supervision are directed toward the achievement of organizational aims.
MGM Studios, Inc. v. Grokster, Ltd., 545 U.S. 913 (2005), is a United States Supreme Court decision in which the Court ruled unanimously that the defendants, peer-to-peer file sharing companies Grokster and Streamcast, could be held liable for inducing copyright infringement by users of their file sharing software. The plaintiffs were a consortium of 28 entertainment companies, led by Metro-Goldwyn-Mayer studios.
Commons-based peer production (CBPP) is a term coined by Harvard Law School professor Yochai Benkler. It describes a model of socio-economic production in which large numbers of people work cooperatively; usually over the Internet. Commons-based projects generally have less rigid hierarchical structures than those under more traditional business models.
Leaderless resistance, or phantom cell structure, is a social resistance strategy in which small, independent groups, or individuals, challenge an established institution such as a law, economic system, social order, or government. Leaderless resistance can encompass anything from non-violent protest and civil disobedience to vandalism, terrorism, and other violent activity.
Peer production is a way of producing goods and services that relies on self-organizing communities of individuals. In such communities, the labor of many people is coordinated towards a shared outcome.
Decentralized computing is the allocation of resources, both hardware and software, to each individual workstation, or office location. In contrast, centralized computing exists when the majority of functions are carried out, or obtained from a remote centralized location. Decentralized computing is a trend in modern-day business environments. This is the opposite of centralized computing, which was prevalent during the early days of computers. A decentralized computer system has many benefits over a conventional centralized network. Desktop computers have advanced so rapidly, that their potential performance far exceeds the requirements of most business applications. This results in most desktop computers remaining idle. A decentralized system can use the potential of these systems to maximize efficiency. However, it is debatable whether these networks increase overall effectiveness.
Wikinomics: How Mass Collaboration Changes Everything is a book by Don Tapscott and Anthony D. Williams, first published in December 2006. It explores how some companies in the early 21st century have used mass collaboration and open-source technology, such as wikis, to be successful.
Rod Beckstrom is an American author, high-tech entrepreneur, and former CEO and President of ICANN. He previously served as Director of the National Cybersecurity Center.
Dynamo is a set of techniques that together can form a highly available key-value structured storage system or a distributed data store. It has properties of both databases and distributed hash tables (DHTs). It was created to help address some scalability issues that Amazon experienced during the holiday season of 2004. By 2007, it was used in Amazon Web Services, such as its Simple Storage Service (S3).
Blessed Unrest: How the Largest Movement in the World Came into Being and Why No One Saw It Coming is a 2007 New York Times bestseller by Paul Hawken. The book is about the many non-profit groups and community organizations, dedicated to many different causes, which Hawken calls the "environmental and social justice movement". Hawken explains that this is a diverse movement with no charismatic leader. The movement follows no unifying ideology, and is not recognized by politicians, the public and the media. But, Hawken argues, it has the potential to benefit the planet.
Seeing Like a State: How Certain Schemes to Improve the Human Condition Have Failed is a book by James C. Scott critical of a system of beliefs he calls high modernism, that centers on governments' overconfidence in the ability to design and operate society in accordance with purported scientific laws.
A blockchain is a distributed ledger with growing lists of records (blocks) that are securely linked together via cryptographic hashes. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Since each block contains information about the previous block, they effectively form a chain, with each additional block linking to the ones before it. Consequently, blockchain transactions are irreversible in that, once they are recorded, the data in any given block cannot be altered retroactively without altering all subsequent blocks.
The InterPlanetary File System (IPFS) is a protocol, hypermedia and file sharing peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content-addressing to uniquely identify each file in a global namespace connecting IPFS hosts.
Decentralized wastewater systems convey, treat and dispose or reuse wastewater from small and low-density communities, buildings and dwellings in remote areas, individual public or private properties. Wastewater flow is generated when appropriate water supply is available within the buildings or close to them.
A digital platform is a software-based online infrastructure that facilitates user interactions and transactions.
