BalanceSeal is an AGPL 3.0+ cryptographic audit module for cryptocurrency exchanges and digital wallets that generates a verifiable, time-frozen snapshot of all user assets at the moment an account is terminated. It aggregates on-chain and off-chain balances, reconciles holdings across systems, locks market pricing at the termination timestamp, and produces tamper-evident reports for compliance, auditing, and transparency. https://roxanneardary.com/balanceseal/

The real estate specifications focus on shifting property data away from centralized listing platforms into locally hosted, machine-readable systems that users can fully control. Each property is structured as a modular dataset with consistent formatting for spatial, financial, and descriptive attributes, allowing it to be reused across applications and AI systems without platform dependency. On top of this foundation, the design incorporates encryption-first principles and blockchain-inspired verification concepts to ensure tamper-resistant records, traceable ownership changes, and secure handling of sensitive information, creating a hybrid model of local control with distributed-style trust and transparency. https://roxanneardary.com/real-estate-specifications/

Blockchain specifications define an institutional blockchain system built on distributed custody using Multi-Party Computation (MPC), where no single entity can access or control private keys. All transactions are governed through policy engines, role-based permissions, and full audit logging instead of centralized custody. It supports tokenization and multi-chain interoperability for real-world assets like real estate and financial instruments, with deployment across on-prem, sovereign cloud, and hybrid environments. The result is a secure, auditable infrastructure for programmable assets with built-in compliance and institutional control. https://roxanneardary.com/blockchain/

Magistrate Title Services is an open-source, AGPL-3.0+ platform that modernizes real estate title and escrow processes using a hybrid blockchain architecture, AI-powered verification, and encrypted data systems. It combines public blockchain transparency with permissioned legal recordkeeping to improve security, reduce fraud, and increase trust in property transactions. https://roxanneardary.com/magistrate-title-services/

RegistryGuide is an open-source vehicle registration, title management, and legal compliance platform designed for government agencies, transportation authorities, tribal governments, and other jurisdictions. Built with a modular architecture, it combines vehicle records, title processing, machine-readable law modules, AI-powered assistance, and optional blockchain-backed ownership verification to create a secure, transparent, and modern vehicle administration system. https://roxanneardary.com/registryguide/

CommonVote System is an open-source, distributed voting infrastructure protocol designed to enable secure, verifiable, and jurisdiction-adaptable elections. It uses end-to-end encryption, cryptographic identity verification, and one-time voting tokens to ensure ballot integrity while preserving voter privacy. The system separates identity, voting, and audit layers, with blockchain-based immutable vote recording and a compliance-driven jurisdiction plugin model that allows states and countries to define legal election rules without modifying the core cryptographic system. https://roxanneardary.com/commonvote-system/
