A community trust management system based on explicit vouches to participate.
Trust Infrastructure on ATproto
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...

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.
Building Unforgeable Professional Endorsements with ATProtocol - Nick's Blog
Traditional professional endorsements on platforms like LinkedIn lack cryptographic proof—anyone could forge them, and the platform controls the truth. This article introduces a two-record architecture using ATProtocol's Content Identifiers (CIDs) and Decentralized Identifiers (DIDs) to create mathematically unforgeable mutual attestations. By separating proof creation from endorsement acceptance and leveraging the firehose for distributed validation, we build a system where both parties cryptographically consent and no central authority can manipulate the record.

Payments on Protocol - Nick's Blog
atprotofans.com was a proof of concept for payments on ATProtocol built at Graze Social. This post is about what we built, why proof of payment on protocol matters, and what it makes possible.

Bluenotes: Community Notes for ATProto
I'll briefly demonstrate Bluenotes, a fork of the Bluesky with Community Notes. Then I'll discuss a proposed "Open Community Notes" standard and lexicon for Community Notes on ATProto, and discuss challenges such as preserving contributor anonymity and defending against manipulation.

Ante: A New Way to Blend Borrow Checking and Reference Counting
Ante has taken the first step towards something we all thought was impossible: blending reference counting and borrow checking without run-time crashes. 0
Excited to share that the official developer docs for the claim-atproto SDK are now live! Developers can now easily build apps to read,write, and publish LinkedClaims natively on the #ATProto network Check out the doc here 🔗 github.com/Cooperation-... @goldavelez.org #LinkedTrust #AtmosphereConf
