Can Blockchain Keep AI Honest? Cardano CEO Thinks So

At Paris Blockchain Week, Frederik Gregaard of the Cardano Foundation delivered a sweeping narrative that tied together the origins of decentralized tech

Frederik Gregaard, CEO of the Cardano Foundation, took to the stage at Paris Blockchain Week to discuss the role of blockchain in an age of artificial intelligence (AI), arguing that the technology could help to keep AI honest.

Gregaard began his presentation by looking back at the origins of decentralized technology, aiming to dismantle financial institutions and remove identity-based exclusion. However, he noted that traditional finance has begun to seep back into the crypto space, bringing with it the same exclusivity that decentralization set out to avoid.

Instead, Gregaard’s real concern lies in the rapidly advancing field of AI. While praising the convenience that AI could bring, he warned that the technology’s reliance on unverified data poses serious risks. Without transparency and traceability, decisions driven by AI—be they political or economic—are built on shaky ground.

This, he argued, is where blockchain must step in: as a backbone for data integrity, supporting a new generation of AI.

Gregaard highlighted how Cardano is already moving in that direction, supporting decentralized land registries in Africa and on-chain financial disclosures. To him, the platform is positioning itself as a public infrastructure for verified truth, with reliable identity systems, interoperable wallets, and open-source tools keeping individuals in control—especially in a world soon to be dominated by autonomous digital agents.

He also noted that Cardano can rival the throughput of systems like Visa, having supported over 90 million transactions in a day, managed by a global web of independent node operators. To him, the narrative that public blockchains can’t scale is outdated.

Concluding his presentation, Gregaard posed a thought experiment: a world where trillion-dollar companies operate with skeleton crews, governed by AI and run through transparent ledgers. In that world, he said, power doesn’t need to be feared—if it’s verifiable. Blockchain, paired with AI, could make every shareholder an informed one.
