Grappa’s Reputation Principles

An effective reputation system reduces the friction required to build trust between people.



With Grappa, users own their badges, which means they are in control of their professional story. False badges can’t be created, and earned badges can’t be taken away. The result is empowered talent who can share their verified reputation on their own terms.



Every piece of information in the system is signed by an Issuer, vouching for the credibility and value of the data. Valuable badges will increase Issuers’ and Talent’s reputations, leading to trusted endorsements.



Grappa’s reputation system is open and permissionless, without any gatekeepers or institutions. This allows market forces to work, ensuring the best information rises to the top.
