Cardano Foundation CEO Says ADA is Bringing Bitcoin’s Core Architecture to Traditional Banking Infrastructure

At Paris Blockchain Week 2026, Cardano Foundation CEO Frederik Gregaard made a series of claims that deserve careful attention — not because they are outlandish, but because they are specific, verifiable, and increasingly difficult to dismiss. Speaking on the main stage and in a series of panel discussions across the event, Gregaard positioned Cardano not as a competitor to Bitcoin but as a complementary layer that takes Bitcoin’s most important architectural innovations and extends them into territory Bitcoin itself cannot reach.

The remarks come at a pivotal moment for Cardano, which has spent years in the shadow of Ethereum and Solana in the public conversation despite maintaining one of the most active developer communities in the industry. If Gregaard’s claims hold up under scrutiny, ADA’s case for institutional adoption may be considerably stronger than its current market position suggests.

ADA and Bitcoin: The Architectural Connection

Gregaard was explicit about the relationship between ADA and Bitcoin’s design principles. “Bitcoin has the superiority of UTXO and the superiority of its architecture,” he said. “ADA borrowed some of these design principles. I think Bitcoin and ADA really work together very well.”

The UTXO — Unspent Transaction Output — model is Bitcoin’s core accounting mechanism. Rather than maintaining account balances like a traditional bank, Bitcoin tracks individual units of currency as discrete outputs from previous transactions. This model is considered more secure and more parallelisable than the account-based model used by Ethereum because each UTXO can be validated independently without reference to a global state.

Cardano adopted an extended version of this model — eUTXO — which adds the ability to carry arbitrary data and logic alongside each transaction output. Gregaard argues this combination gives Cardano the security and architectural clarity of Bitcoin alongside the programmability that Bitcoin itself lacks.

Banking-Grade Identity on the Blockchain

Perhaps the most substantive claim Gregaard made at Paris Blockchain Week concerns Cardano’s role in the global banking identity infrastructure. He stated that Cardano is the only blockchain capable of implementing the Legal Entity Identifier — a 20-character alphanumeric code used by financial institutions worldwide to uniquely identify legal entities participating in financial transactions.

This system underpins the authentication and verification infrastructure of the modern banking world. Every financial institution involved in regulated markets requires an LEI. Gregaard’s claim is that Cardano has built the capability to anchor these identifiers on-chain, creating an immutable and publicly verifiable record of institutional identity that does not rely on a centralised registry.

The practical application of this is already live. Gregaard disclosed that accounting firm Grant Thornton has used Cardano’s LEI implementation to conduct full architectural audits of financial transactions — examining every transaction rather than the traditional spot-check approach — reducing audit costs for institutions by approximately 50%.

Programmable Bitcoin on Cardano

One of the more forward-looking statements Gregaard made concerns the integration of Bitcoin directly into Cardano’s programmable layer. “There is a lot of work being done to bring Bitcoin to Cardano — programmable DeFi with BTC, using Satoshis as gas fees natively on Cardano,” he said. “So you get programmability without leaving Bitcoin. That will unlock a lot of things.”

This is a direct response to one of Bitcoin’s most persistent limitations: it is extraordinarily secure and reliable as a store of value and settlement layer, but it cannot natively support the kind of complex financial logic that DeFi protocols require. Various solutions — Lightning Network, Rootstock, Stacks — have attempted to add programmability to Bitcoin without compromising its base layer security. Gregaard is positioning Cardano as the most architecturally coherent of these approaches, given its shared UTXO foundations.

The Visa Claim: Can Cardano Really Scale?

Gregaard made one of the boldest claims heard at any blockchain event this year when he stated that Cardano can already run at Visa-level transaction throughput. “Yes, you can run Visa and MasterCard on a public permissionless blockchain,” he asserted. “We did over 90 million transactions in one day, fully secured by 3,000 stake pool operators.”

Visa processes approximately 150 million transactions per day at peak capacity. Cardano’s claimed 90 million in a single day — if verifiable — would put it within the same order of magnitude. This figure is significantly higher than most public estimates of Cardano’s throughput, and independent verification would be required before drawing firm conclusions.

What is not in dispute is that Cardano’s architecture has been designed from the ground up for scalability through its layered approach — separating the settlement layer from the computation layer — and through its Hydra scaling solution, which allows payment channels to be opened off-chain and settled on-chain in batches.

Real-World Deployments: London Stock Exchange and NASA

Beyond the architectural claims, Gregaard pointed to two real-world deployments that give Cardano’s institutional ambitions concrete grounding. First, Cardano partnered with Members Cap to tokenise exposure to Hannover Re — one of the world’s largest reinsurance companies — and list the resulting product on the London Stock Exchange. The asset yields between 10% and 17% and represents a genuine bridge between traditional capital markets and blockchain infrastructure.

Second, and perhaps more surprisingly, Gregaard confirmed an ongoing collaboration with NASA around data provenance, track-and-trace solutions, and satellite data applications. “NASA has code running on Cardano today,” he stated. The partnership uses Cardano’s Merkle Patricia Tries data structure to handle large-scale, constantly updating datasets — a capability Gregaard claims is not present in other major blockchain networks.

These are not speculative partnerships. A product listed on the London Stock Exchange and a confirmed NASA collaboration represent a level of institutional validation that most blockchain projects have not achieved.

What This Means for ADA’s Price

ADA is currently trading in a compressed range, forming what technical analysts describe as a descending wedge pattern since February. The upper trendline continues to slope downward while the lower support rises gradually — a structure that historically resolves with a breakout in either direction.

The fundamental case Gregaard outlined at Paris Blockchain Week — LEI integration, programmable Bitcoin, London Stock Exchange listings, NASA collaboration — represents the kind of genuine institutional adoption that has historically preceded significant ADA price movements. Whether the market will reprice ADA to reflect this activity is a separate question from whether the activity is real, and the evidence suggests much of it is.
