Satoshis as Gas: Cardano Foundation's Frederik Gregaard on Bitcoin + Cardano, Quantum, and On-Chain Audit

In this episode of Bitcoin.com News Interviews, host speaks with Frederik Gregaard, CEO of the Cardano Foundation, during Paris Blockchain Week 2026. Gregaard outlines Cardano’s strategic vision of integrating Bitcoin into its ecosystem by enabling Satoshis to serve as native gas fees on Cardano, allowing users to retain Bitcoin while accessing programmable DeFi. He emphasizes the architectural synergy between Bitcoin’s UTXO model and Cardano’s enhancements, particularly in identity, privacy, and real-world asset (RWA) tokenization. A major focus is on Cardano’s use of the Legal Entity Identifier (LEI) and Verified LEI (VLEI) to bridge TradFi and Web3, enabling regulatory compliance and trust. The discussion also covers quantum readiness, with Gregaard asserting that both Bitcoin and Cardano are well-positioned due to their architecture, and that Cardano’s research into quantum-resistant cryptography and AI agent identity—via the Sokosumi platform—positions it as a leader in next-gen security. The episode concludes with a deep dive into Midnight, Cardano’s privacy layer, and its potential to unlock institutional adoption in sectors like healthcare and trade finance, all while maintaining compliance with global regulations like GDPR and AML. Key takeaways include: (1) Bitcoin can be used as gas on Cardano without leaving the Bitcoin network, unlocking new DeFi use cases; (2) Cardano’s integration of TradFi standards like LEI enables real-world regulatory compliance and institutional trust; (3) The foundation is pioneering quantum-resistant infrastructure and AI agent identity to future-proof the ecosystem; (4) Privacy via Midnight and compliance via VLEI allow Cardano to serve both retail and enterprise needs; (5) On-chain audits using real-world auditors like Grant Thornton validate transparency and build trust in blockchain-based financial systems; (6) Tokenizing high-barrier assets like reinsurance portfolios democratizes access to capital markets; (7) Cardano’s approach balances innovation with practicality, focusing on utility over speculation; (8) The vision is to create a decentralized, privacy-preserving, and auditable global financial and social infrastructure.
