Understanding Zero-Knowledge Transport Layer Security and how it enables privacy-preserving proofs of government data without server cooperation. Learn how we extract verified NFS-e data while keeping sensitive information hidden.
Deep dive into Zero-Knowledge Virtual Machines (SP1/RISC Zero) that enable verifiable computation of complex credit models written in Rust, without revealing input financial data or intermediate steps.
Why credit scores shouldn't be tradeable NFTs. Exploring ERC-5192 standard, the economics of reputation markets, and how SBTs prevent identity fraud while enabling verifiable credentials.
How we use Mina Protocol's zkApps to bind Soulbound Tokens to specific devices via cryptographic fingerprinting, creating an additional security layer that prevents wallet compromise attacks.
Economic analysis of why DeFi protocols require 150-200% overcollateralization and how zero-knowledge solvency proofs enable 50% collateral ratios without sacrificing security. The $5.2T credit gap solution.
How Zolvency integrates with Brazilian government systems (NFS-e, PGDAS-D, e-CAC) to verify income for 15+ million Micro-Entrepreneurs, reducing lending costs from 45-65% APR to DeFi's 5-12% rates.
Complete implementation guide for using tlsn-js to generate ZK proofs from nfse.gov.br, including cookie redaction, selective disclosure, HTML parsing, and on-chain verification with gas optimization.
Technical deep-dive into implementing the Soulbound Token standard with on-chain SVG generation, tier-based gradients (Gold/Silver/Bronze), and achieving 100% test coverage with Foundry.
Evolution of credit scoring systems from centralized bureaus (Experian, SERASA) to decentralized zero-knowledge proofs. Why privacy isn't just a feature—it's a requirement for LGPD/GDPR compliance.
Mathematical proofs that Zolvency's construction satisfies completeness (honest users always succeed), soundness (adversaries can't forge proofs), and zero-knowledge (no data leakage beyond predicates).
