Cardano Foundation on Why 2026 Will Redefine AI Authority, Digital Identity and Privacy

2026 will mark a major shift in how humans interact with artificial intelligence, according to Cardano Foundation executive Thomas Mayfield.

Speaking about the next phase of digital trust, Mayfield said AI agents will soon be granted delegated authority to act on behalf of people, moving beyond passive assistance into active decision-making roles.

“In 2026, I anticipate a significant shift where agentic AI will be granted delegated authority to make active decisions on behalf of individuals,” said Mayfield, who leads decentralized trust and identity solutions at the Foundation.

He argues that properly designed AI agents could surpass human-led processes in security and fraud resistance, particularly when combined with decentralized identity frameworks.

Governments Take the Lead on Digital Identity

Contrary to expectations that Big Tech would dominate digital identity, Mayfield believes governments will move faster. He predicts that national ID schemes will become the first large-scale adopters of decentralized identity (DID) technology, driven by the need for secure, interoperable public services.

These government-backed identity systems are expected to integrate with corporate identity frameworks and eventually extend into supply chains.

Mayfield sees this convergence as laying the groundwork for a trusted digital infrastructure across sectors, from public services to enterprise operations.

EU Regulations Force Corporate Identity Rethink

New European Union regulations will act as a major catalyst in 2026, pushing enterprises to overhaul how they manage identity and data.

Mayfield expects rising demand for verifiable data as compliance requirements expand across supply chains, particularly through mechanisms such as Digital Product Passports (DPPs).

To meet these demands, solution providers will need to support cross-domain secure attribution, ensuring identity and data can be verified across multiple ecosystems.

The challenge, Mayfield said, will be balancing interoperability and ease of use with privacy, self-sovereign controls, and long-term security, especially when it comes to sensitive customer data, intellectual property, and trade secrets.

Digital Product Passports Without Surveillance

Mayfield described DPPs as a potential antidote to surveillance-heavy data models. A self-sovereign approach would allow participants in a value chain to selectively disclose information, using off-chain storage for private data and on-chain records for verifiable public data.

He also called for regulatory safeguards to prevent data verifiers from storing and reselling personal or commercial data, warning against enrichment practices that undermine privacy.

The views come as Cardano, the tenth-largest cryptocurrency network with a market value of around $25 billion, expands its real-world footprint.

The Cardano Foundation has recently launched collaborations with FC Barcelona, Veritree, and Petrobras, showing its push into enterprise, sustainability, and government-facing use cases.

2025 was a monumental year for Cardano.

Cardano completed its transition to fully decentralized governance, with the community now steering the protocol through live votes, a ratified Constitution, and an operational treasury.

Taken together, Mayfield’s outlook suggests 2026 could be a turning point—where AI authority, decentralized identity, and privacy-first infrastructure converge to reshape digital trust at scale.
