U°OS introduces a new type of blockchain transactions — social. The social transaction is a reaction of network participants on each other’s activity recorded in a public distributed ledger. In addition to account balance and its financial transactions, U°OS also operates with social interaction, which creates a more holistic portrait of our digital identity owned to us on the sovereign rights.

The U°Community dApp uses this type of transactions to upvote, downvote, publish content and follow or trust users — this is just one of the countless potential use cases for social transactions.

Social transactions along with economic ones are used to determine Importance° of each account by calculator nodes – the community-owned nodes that perform importance° score calculation and distribute the resulting scores back to the network.
