Abstract: Methods, systems, and apparatus including computer programs encoded on computer storage media for implementing a decentralized social-media network. The system platform servers of a social-media platform and a stand-alone client, instances of which are downloadable to and executable on devices of end users to interface with the platform servers. The servers have computer-executable instructions to compute a measure of reputation based on engagements within a community, including moderation work of community content, and based on highly idiosyncratic community-specific rules. The stand-alone client has computer-executable instructions to generate and store a public-private key pair, which is accomplished to the exclusion of the servers. The key pair enables recording of the measure of reputation and related changes on decentralized computing resources in a way that is verifiable.
