Scuttlebutt

Scuttlebutt is slang for gossip, particularly among sailors. It is also the name of a peer-to-peer system ideal for social graphs, identity and messaging.

The unique properties of Secure Scuttlebutt (SSB) make it possible for digital information to spread easily even in the absence of Internet Service Providers (ISP) and the internet’s backbone. What makes that possible is a decentralized protocol based on the mechanics of word of mouth.

Scuttlebutt is decentralized in a similar way that Bitcoin or BitTorrent are. Unlike centralized systems like PayPal or Dropbox, there is no single website or server to connect when using decentralized services. Which in turn means there is no single company with control over the network.

However, Scuttlebutt differs from Bitcoin and BitTorrent because there are no “singleton components” in the network. When accessing the BitTorrent network, for instance, you need to connect to a Distributed Hash Table (DHT, think of it as a huge round table where anyone can come and take a seat). However, to get access to the DHT in the first place, you need to connect to a bootstrapping server, such as router.bittorrent.com:6881 or router.utorrent.com:6881. These are very lightweight servers which simply introduce you to the DHT. They still depend on the existence of ISPs and the internet backbone. Also, those systems are concerned about public information. For instance, with Bitcoin, each peer stores the entire log of all transactions ever sent by anyone.

Secure Scuttlebutt is also different to federated social networks like Mastodon, Diaspora, GNU social, OStatus. Those technologies are not peer-to-peer, because each component is either a server or a client, but not both. Federated social networks are slightly better than centralized services like Facebook because they provide some degree of choice where your data should be hosted. However, there is still trust and dependency on third-party servers and ISPs, which makes it possible for admistrators of those to abuse their power, through content policies, privacy violations or censorship.

 In Scuttlebutt, the “mesh” suffices. With simply two computers, a local router, and electricity, you can exchange messages between the computers with minimal effort and no technical skills. Each account in Scuttlebutt is a diary (or “log”) of what a person has publicly and digitally said. As those people move around between different WiFi / LAN networks, their log gets copy-pasted to different computers, and so digital information spreads."
