Zero-knowledge proofs, attested data, and escrowed transactions

1. Privacy: Allows you to privately prove something without sharing who you are. Eg. For verification, credentials, etc.
2. Ease of integration: Code, and create conditional statements, using outputs of any service without API access. Eg. To connect outputs of two separate services.
3. Trustless escrow: Trust code, rather than a third party. Eg. To create an order book public infrastructure.
4. Trustless collaboration: Trust code was executed correctly among a non-trusting group. To analyze or do benchmarks without sharing data.

• For all, reduce cost of quality control, dispute resolution, and customer support

Attestation is an official verification of something as true or authentic, by certifying the validity of a document and the signatures on it.

1. Managed Auctions (e.g., Christie’s, Namecheap):
• Manage the auction process, including listing, bidding, and finalizing sales. They often incorporate escrow services for high-value items. Value add outside of the sale itself - Increase sales price by better education, scarcity, reputation, and limited time nature; Guide buyers to, and get them access to, the right objects via concierge
• Involves competitive bidding, which is not a feature of the other categories.
2. Peer-to-Peer Asset Transfer (e.g., PlayerAuctions):
• Facilitates direct transactions between individuals for assets, often including digital assets.
• Direct transfer of assets between peers, possibly with less oversight
3. Payment for Services or Goods (e.g., Uber drivers, Upwork, Etsy handmade goods):
• Mediate the provision of services, handling payment and often quality control.
• Services rather than goods, involving different dynamics like service quality assessment.
4. Payment for Online Goods That Can Be Duplicated (e.g., Gumroad, Etsy digital goods):
• Facilitate the sale of digital goods
• Intellectual property and distribution.

• What data in web2 do we need to bring to web3?
• Is there a trusted institution that does this or do we need to use all sorts of zk tech?
• What platforms can you build upon that already have the requisite data?
• Eg. Base, BSC, appchains, etc
• What use cases are there in untrusted computing environments?
• What digital voting systems are least trusted?
• What managed marketplaces spend significantly on quality control, dispute resolution, and customer support?

• Whether it’s poor pricing, unclear financial strength of institution, etc.
• Natural disaster insurance (earthquake warnings from recognized agencies), travel (flight delay), crop insurance (weather conditions), supply chain (verified shipping data), etc.
