Decentralized Social Network

https://joinmastodon.org

A social decentralized network without advertising, similar to Twitter or Weibo.
~ 4.5 million users.

Thousands of independent communities, using Mastodon, form a common network where each planet, despite its differences, is part of something in common.

Thanks to the distribution of the network, many moderators are ready to help you, and there are also nodes with stricter behavioral requirements.

You can run your social platform with your own infrastructure. Do not rely on other companies that can change the rules of the game at any time - set your own rules.

The social network is supported by the community and is not owned by any person or organization.

A network of nodes, or pods, that are located in different individuals and organizations.
Each node runs on its own copy of the engine, being essentially a separate web server.
Network users can create an account on any one of these servers, but will still interact with all other servers.

Posts can be public or limited.
Restricted posts can only be read by a particular group or groups.
Besides existing groups (friends, family, work ...), you can create your own.
You can read the posts of another user without adding them to your friends.
The ribbon can be filtered by groups.

Export messages to Facebook, Twitter, Tumblr and Wordpress.

Decentralized network of hubs.
A platform for creating social networks with a transparent identification system and access control tools.

Hubs are servers that exchange data in the network "grid". All hubs are equal. Hubs can be linked to one or more third-party hubs depending on the need.

The channel is the main element in the grid. A channel can be represented in different ways: a private page, blog or forum. Channels can be linked to other channels to share information according to flexibly configurable access rights. The channel address is in the usual format: channel@hub.domain.

Transparent migration means real control over your data.
In Habzilla, you have an account in the grid rather than on a particular server and this account can move around the grid.
You can clone a channel to several hubs to increase resistance to network failures and counteract censorship, or you can migrate a channel from one hub to another with all your data and contacts.

You can link the cloud storage of your channel's files to your hard drive.

The world's 1st cryptographic video platform, decentralized and built using the infrastructure provided by the STEEM blockchain, along with the IPFS P2P network.

And simpler?
A video streaming video hosting service that uses blockchain technology for the database.
This makes it decentralized, like Torrent or Telegram Messenger. That is, there is no single place where it is located, and therefore it is impossible to block it.
Which means if YouTube gets blocked, you can safely use this video hosting.

The only way to block it is to disable the Internet, as Lukashenko did in Belarus. But you won't be able to block it for long. In Belarus, ATMs stopped working and had to bring back the Internet, otherwise there would be a collapse.
