snowblossom channel had been up and running for a while.
https://wiki.snowblossom.org/index.php/Channels"Without going into a great amount of technical detail, the basic concept for Snow Channels is that a content creator creates a channel. The channel can be whatever content they want, like a blog or a instagram style series of pictures or a discussion group. The channel creator controls what goes on the channel completely.
People who want to read the channel subscribe to it. When they do, they become peers and help distribute the channel to others. Think of it like blockchain combined with bittorrent. It is like blockchain in that a bunch of peers that don’t trust each other can use a blockchain to agree on what the current best state is and what all of the history is that lead to that state. It is like bittorrent in that peers share content with each other."
