Professional recommendations have a trust problem. Anyone can write a glowing review and claim someone else said it. How do you know it's real? We built endorsements on at://work using ATProtocol's cryptographic infrastructure.

Unlike traditional platforms where the company owns your reputation data, your endorsements live on your PDS. You own them. They move with you across the ATProtocol ecosystem. Your reputation is truly yours.

When someone endorses you, both parties must publish signed proof records to their Personal Data Servers. No forgeries, no fakes.

The magic? Content Identifiers (CIDs). They're cryptographic hashes of the endorsement content. Change one character and the CID changes completely. Both parties must commit to the same CID for the endorsement to verify.

When you receive an endorsement, you have complete control. Accept it and both your proof and the endorsement get published. Reject it and nothing ever becomes public. No passive acceptance, only active consent.

Try it at atwork.place. Give endorsements to colleagues you've worked with, accept ones you receive, and build a cryptographically-verified professional reputation on the decentralized web.
