Mastodon is a social network[2] that operates on a federated system, also known as the Fediverse. This free and open-source platform, which was launched in October 2016, allows users to post short messages, referred to as toots, of up to 500 characters. Users are free to join specific servers each with its unique rules and themes. Mastodon employs a community-based approach to moderation, offering mechanisms to filter content, block and report users. Its search capability is limited to hashtags and mentioned accounts, differing from Twitter[3]’s comprehensive full-text search. Despite potential security[4] challenges owing to its decentralized structure, Mastodon has implemented measures to address vulnerabilities like DDoS attacks and data breaches. The platform is primarily crowdfunded, does not run ads, and operates as a registered nonprofit organization[1] in Germany.

Définitions des termes
1. nonprofit organization.
1 A nonprofit organization is a type of legal entity that operates primarily for the collective, public, or social benefit, rather than for the personal profit of its owners or shareholders. These organizations are characterized by their accountability, trustworthiness, and openness. They can apply for tax-exempt status which allows them to receive contributions that are tax-deductible for the donor. Nonprofits encompass a wide range of organizations, including political entities, schools, and churches. In the United States, there are over 1.5 million registered nonprofit organizations. They largely rely on various income sources such as donations, sponsorships, and government funding. Nonprofits face unique challenges such as balancing staff salaries with expenses for beneficiaries and competition for talent with the public and private sectors.
2 A nonprofit organization is a lawful establishment that operates primarily for the communal, public, or societal benefit. Unlike for-profit businesses, nonprofits are bound by a non-distribution constraint, meaning any profit made isn't distributed to owners or shareholders. Instead, these organizations focus on accountability, trustworthiness, and transparency with the aim to boost public confidence and support. They often supply public goods or services that are insufficiently provided by the government. Nonprofits can vary widely in their structure, purpose, and legal classification. They operate under laws that govern their creation and management in most countries. Fundraising is a critical aspect of a nonprofit's financial stability and often includes donations, sponsorships, and government funding. Nonprofits also face unique challenges, including resource management and competition for talent.
2. social network.
1 A social network, as the term suggests, is a system that connects various individuals or organizations, also known as social actors. It's not just about online platforms like Facebook or Twitter, but about the intricate web of connections between these actors. The relationships, known as dyadic ties, allow for interaction and communication. By studying these networks, we can identify patterns and understand how influence works within the group. The field of social network analysis has roots in several areas such as social psychology, sociology, statistics, and graph theory. It's an evolving interdisciplinary field that uses various methods to analyze these social structures and provides theoretical explanations for the observed patterns. Key figures like Georg Simmel and Jacob Moreno have made significant contributions to this field.

Each user is a member of a specific Mastodon server that can interact seamlessly with users in any other server. This is intended to give users the flexibility to select a server whose policies they prefer, but keep access to a larger federated social network. Mastodon is powered by the ActivityPub protocol, making it part of the Fediverse ensemble of services such as Lemmy, Pixelfed, Friendicaet PeerTube.

Mastodon was created by Eugen Rochko and announced on Hacker News in October 2016, and gained significant adoption in 2022 in the wake of Twitter's acquisition by Elon Musk.

The project is maintained by German non-profit Mastodon gGmbH. Mastodon development is crowdfunded and the code does not support advertisement.
