I agree with Nick that you have noted a big hard problem, with Zooko’s triangle type trade-offs. (For a semi-related example that is “easier” but still crazy difficult, see our “PeerFlow: Secure Load Balancing in Tor” https://doi.org/10.1515/popets-2017-0017 ) As noted or implied already in this thread: in the end, if someone can cheaply spin up indefinite unlinked identities and build good reputations for them, and if trust is based on such reputations, it is hard (impossible?) to avoid them s...
MeritRank: Sybil Tolerant Reputation for Merit-based Tokenomics*
Decentralized reputation systems are emerging as promising mechanisms to enhance the effectiveness of token-based economies. Unlike traditional monetary incentives, these systems reward participants based on the actual value of their contributions to the network. However, the advantages and challenges associated with such systems remain largely unexplored. In this work, we investigate the inherent trade-offs in designing a decentralized reputation system that is simultaneously generalizable, trustless, and Sybil-resistant. Specifically, “generalizable” means that the system can assess various types of contributions across different contexts, “trustless” indicates that it functions without the need for a central authority to oversee reputations, and “Sybil-resistant” refers to its ability to withstand manipulations by fake identities, i.e., Sybil attacks.

If WSocial sold people on the idea that everyone they would interact with is ID-verified, then indeed, every single open ATProto community would act as a back door of sorts. The only way for them to deliver would be to de-federate entirely. And it's always a bad idea to bet against openness.
EigenTrust
The EigenTrust algorithm is a reputation management algorithm for peer-to-peer networks, developed by Sep Kamvar, Mario Schlosser, and Hector Garcia-Molina.[1] The algorithm provides each peer in the network a unique global trust value based on the peer's history of uploads and thus aims to reduce the number of inauthentic files in a P2P network. It has been cited by approximately 5800 other articles according to Google Scholar.[2]

Introducing attested.network: Proof of Payment for ATProtocol - Nick's Blog
attested.network is an open spec for decentralized proof of payments on ATProtocol, built on what we learned making atprotofans.com. It formalizes the three-party attestation model and opens it up for any app to implement.
Trust and Faith in Our Web
I’m not Brennan, but I’m very interested in decentralization and a fan of AtProto specifically, so I’d like to weigh in. First I should mention I’ve personally never been able to get into microblogging, so I haven’t touched bluesky myself, despite having an account for ATProto reasons. But I agree it’s concerning that the company chooses to continue to host the content of harmful individuals and calling that act “neutral”. I’m certainly against the idea of the “marketplace of ideas” as it’s cle...
atproto offers an fascinating example of what it means to restructure this relationship. End-users get to choose who and how much trust they delegate to software producers, the delegation of trust becomes tangible and revokable.

Networked computing, in a fundamental way, changed the producer-consumer relationship we have with corporations. In the material world that relationship ends with the transfer of material and money; I buy a pencil and some paper, and the producer is out of the picture while I use them to write.

I know, Daniel, but that's not the way WSocial "sold" it to us. We could only access trough ID-verification so we know for 100% they are EU and a "real person". That was the whole point. So we went trough that process, but now it seems that the backdoor are the other ATProt platforms to get in too.
As atproto matures, adversarial actors will reveal all the places where trust is implicit rather than managed - maybe time to build reputation mechanisms for PDSs like we do for email servers? It'll likely need to be default-block/prove-healthy, or default throttle until proven typical?

They've got a huge network that I'm in the process of graphing. They're now setting up their own PDSes. It's sophisticated.
