#EthCC talk: Sybil Resistance for a more democratic web3 by @owocki

TLDR: Boosting decentralized coordination and trust via identities utilizing soulbound and DID systems.

To begin with, Kevin went through a list of answers to his "what is the purpose of Web 3" question. This was my favorite:

@carl_cervone: "to regenerate the world by taking the most powerful coordination tool invented - money - and reprogramming it with different values."

Decentralized Society 101:

- A soul (account)
- A credential that encodes into a soul's state
- An entity that creates a cluster of souls

Idea is to take our on-chain identities and marking up that data with Soulbound tokens or DIDs that can have someone attest to that account via an authorizing trusted entity — eg every time you contribute to a Gitcoin grant round, Gitcoin can issue a SBT that tags your address.

More Examples of DeSoc use-cases that can build up one’s reputation.

With enough identifiers, you can start creating an interconnected web of trust.

This enables intersectional identity. Which allows for:
* DeFi protocols to assess trust (use your reputation as collateral) cc @RMRK
* Sybil resistance
* Pluralistic identity that creates cooperation across social distance

(cont'd)
* NFT artists can ensure they whitelist people who care (imagine an art appreciator score (; cc @justinaversano @quantumNFT may be interested :)
* Good faith actors to get heightened governance powers when voting.

This web of trust allows you to measure social proximity. Here is some math courtesy of @VitalikButerin & @poojaranjan19 on how this could work.

This is really cool, and @0xPARC actually made a ZKfied variant of this for ETHNY and won a prize through Optimism!
