Wiki

A wiki is a type of collaborative website that allows users to easily create, edit, and link content through their web browser, often without needing special software or logins. The most famous example is the online encyclopedia Wikipedia.

Key Characteristics

• Collaborative: Wikis are designed for groups of people to share ideas and information quickly. Content creation is a collective effort, without a defined owner for specific pages.
• Easy Editing: Content is typically edited using a simplified markup language or a rich-text editor that functions like a word processor.
• Interlinked Pages: The structure relies heavily on links between pages, allowing information to be organized according to the users' needs.
• History Tracking: Wiki software keeps a history of all revisions, making it easy to monitor changes, spot errors, and reverse unwanted edits.

Wikis can be centralized or decentralized

Decentralized wikis are wiki systems that distribute content across many computers (nodes) instead of a single server, using technologies like IPFS or blockchain, offering censorship resistance, high availability, and new collaboration models like token rewards for contributors (e.g., Lunyr, WikiChain). They aim to be more inclusive and robust than traditional wikis (like Wikipedia), allowing for offline access and preventing single points of failure, with concepts like P2Pedia showing how to manage trust and multiple versions of pages in a distributed environment.
