We discuss the pros and cons of this protocol, and show how it could be employed to create a separating equilibrium between honest and dishonest users. The core idea of the proposal is to allow users to publish a zero-knowledge proof, demonstrating that their funds (do not) originate from known (un-)lawful sources, without publicly revealing their entire transaction graph. This is achieved by proving membership in custom association sets that satisfy certain properties, required by regulation or social consensus. The proposal may be a first step towards a future where people could prove regulatory compliance without having to reveal their entire transaction history.<\/jats:p>","DOI":"10.2139\/ssrn.4563364","type":"posted-content","created":{"date-parts":[[2023,9,8]],"date-time":"2023-09-08T23:54:51Z","timestamp":1694217291000},"source":"Crossref","is-referenced-by-count":13,"title":["Blockchain Privacy and Regulatory Compliance: Towards a Practical Equilibrium"],"prefix":"10.2139","author":[{"given":"Vitalik","family":"Buterin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacob","family":"Illum","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Nadler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabian","family":"Sch\u00e4r","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ameen","family":"Soleimani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"78","reference":[{"issue":"2","key":"ref1","first-page":"122","article-title":"Tornado cash and blockchain privacy: A primer for economists and policymakers","volume":"105","author":"M Nadler","year":"2023","journal-title":"Federal Reserve Bank of St. Louis Review"},{"key":"ref2","author":"A Soleimani","journal-title":"2023, gitHub repository"},{"key":"ref3","author":"S Nakamoto","year":"2008","journal-title":"Bitcoin: A peer-to-peer electronic cash system"},{"key":"ref4","author":"S Meiklejohn","year":"2013","journal-title":"A fistful of bitcoins: Characterizing payments among men with no names"},{"key":"ref5","author":"C Kang","year":"2020","journal-title":"De-anonymization of the bitcoin network using address clustering"},{"key":"ref6","year":"2023","journal-title":"Ethereum name service, decentralised naming for wallets, websites, & more"},{"key":"ref7","author":"G Maxwell","year":"2013","journal-title":"Coinjoin: Bitcoin privacy for the real world"},{"key":"ref8","author":"J Liu","year":"2004","journal-title":"Linkable spontaneous anonymous group signature for ad hoc groups"},{"key":"ref9","author":"B Goodell","year":"2019","journal-title":"Concise linkable ring signatures and forgery against adversarial keys"},{"key":"ref10","author":"M Moser","year":"2018","journal-title":"An empirical analysis of traceability in the monero blockchain"},{"key":"ref11","author":"V Buterin","year":"2021","journal-title":"An incomplete guide to rollups"},{"key":"ref12","article-title":"Why and how zk-snark works","author":"M Petkus","year":"1906","journal-title":"CoRR"},{"key":"ref13","author":"A Berentsen","year":"2023","journal-title":"An introduction to zero-knowledge proofs in blockchains and economics"}],"container-title":[],"original-title":[],"deposited":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T16:13:50Z","timestamp":1786724030000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ssrn.com\/abstract=4563364"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2023]]},"references-count":13,"URL":"https:\/\/doi.org\/10.2139\/ssrn.4563364","relation":{},"subject":[],"published":{"date-parts":[[2023]]},"subtype":"preprint"}}
