Ethereum researcher Toni Wahrstätter published a proposal this week to introduce native UTXOs into Ethereum’s payment layer, treating simple payments as one-shot objects rather than permanent state entries. The design could reduce Ethereum’s permanent state for payment workloads by up to 99.8%. Charles Hoskinson, the founder of Cardano, went on X and then livestreamed his response. ‘EUTXO is the biggest innovation of the smart contract world and Ethereum cannot mention it as they literally try to copy it,’ he wrote. ‘It is literally a crime in the Ethereum inner circles to mention Cardano.’
The question worth asking is not whether Hoskinson is right to be annoyed. It is what this moment actually tells us about the two chains, and whether Cardano being architecturally ahead on EUTXO and staking translates into anything meaningful for ADA holders or builders. The answer is more nuanced than either community wants to hear.
What EUTXO Is and Why Hoskinson Thinks It Matters
Ethereum uses an account model. Every address has a running balance. When ETH or an ERC-20 token arrives at an address for the first time, a permanent entry is written into Ethereum’s state. That entry never disappears even if the address never transacts again. Wahrstätter’s proposal, published this week and triggering the Hoskinson response, argues that most simple payments do not need a permanent record. His design stores only a small spent marker in state and keeps the payment data in blockchain history. He says this mirrors Bitcoin’s UTXO model, where a payment exists once, gets spent once and then leaves the active ledger.
Cardano’s EUTXO extends Bitcoin’s UTXO model to handle smart contracts. Instead of an account maintaining ongoing state, each transaction consumes specific unspent outputs and creates new ones. The key properties are predictability, you can calculate the exact fee before submitting a transaction, no surprises, and parallelism, because UTXOs are independent objects, multiple transactions can be validated simultaneously without conflicts. Hoskinson’s Chimeric Ledgers paper, published with IOG in 2018, formally described how to run both UTXO and account systems in parallel, precisely the hybrid approach Wahrstätter is now exploring for Ethereum. Hoskinson noted in his livestream that the Wahrstätter proposal makes no reference to Cardano or to that paper despite the conceptual overlap.
The honest counterpoint is what Wahrstätter himself said: his proposal borrows from Bitcoin’s UTXO model, not Cardano’s EUTXO. The distinction matters technically. Bitcoin UTXOs handle simple value transfers. Cardano’s EUTXO handles smart contract execution on top of that model. Wahrstätter’s proposal is specifically for simple ETH and ERC-20 payments, not for generalising UTXO to smart contracts across Ethereum. Whether the conceptual debt runs through Bitcoin only or also through Cardano is a legitimate architectural debate, not a settled fact.

The Staking Story: Cardano Was Five Years Ahead
The EUTXO debate is the latest chapter in a longer pattern. Cardano launched its Shelley upgrade in July 2020, transitioning to Proof of Stake and introducing its native liquid staking model where ADA holders delegate to a stake pool without locking funds. You keep your ADA. You spend it whenever you want. You earn rewards continuously through Ouroboros, Cardano’s PoS consensus mechanism. No lockup. No slashing. No bonding period. No derivative token needed to stay liquid while staking.
Ethereum completed its own move to Proof of Stake in September 2022, with the Merge. That is more than two years after Cardano, and the contrast in implementation is significant. Ethereum requires validators to stake 32 ETH to run a node. It has slashing penalties. Withdrawal queues can delay access to staked funds. Most retail users access Ethereum staking through Lido, which issues stETH, a liquid derivative representing staked ETH. You need a synthetic asset to stay liquid while staking on Ethereum. Cardano users never did.
Hoskinson made this point directly in his follow-up commentary: ‘You have to lock your funds, and have slashing and bonding, and all this garbage, and create synthetic assets like Lido. There is no locking in Cardano.’ The pattern holds: Cardano pioneered PoS without lockups in 2020, Ethereum arrived at PoS in 2022 with a more complex implementation that created an entire derivative ecosystem around it. Cardano was architecturally ahead and got less credit for it than its design merited.

Does Being Right First Make Cardano a Better Chain?
This is the question the EUTXO debate dances around without answering. Hoskinson is probably correct that Cardano’s EUTXO influenced the design space Ethereum is now exploring, and almost certainly correct that Cardano’s liquid staking model was cleaner from day one. Being architecturally correct and being widely adopted are two different things, and the gap between them is where Cardano’s story lives.
Ethereum has more than 4,000 active dApps. It processes billions of dollars in daily DeFi volume. Its developer ecosystem is the largest in crypto. Every major tokenization platform, BlackRock’s BUIDL, Ondo Finance, Securitize, uses Ethereum as its primary chain. When Vitalik Buterin published his Lean Ethereum roadmap this week, the same roadmap Hoskinson accused of borrowing Cardano’s ideas, it was being read and discussed by tens of thousands of developers. Cardano’s ecosystem, while genuinely growing with RealFi, Midnight, Voltaire governance and Leios approaching, is still a fraction of that in active usage.
The honest framing: Cardano has produced real architectural innovations that the broader industry is now taking seriously. That is not a small thing. The Ethereum researchers proposing UTXO-style improvements to the world’s most-used smart contract platform are engaging with ideas Cardano spent a decade refining. Whether they credit it or not, the intellectual lineage runs through Cardano’s work. That matters for builders who care about research-grounded design.
Will Cardano Ever Exceed Ethereum?
The direct question deserves a direct answer: not in the metrics that matter most in the near term. Ethereum’s network effects in DeFi, developers and institutional adoption are enormous and self-reinforcing. Every new tokenization platform that launches on Ethereum adds to the gravity. Cardano would need not just better technology but a decisive reversal of that gravity, which historically has not happened between blockchain platforms once the gap is this large.
The more realistic scenario is a different kind of winning. Cardano is building toward a specific market: institutional DeFi that requires regulatory compliance, privacy via Midnight, and formal verification. RealFi targets real-world credit. The van Rossem hardfork proved the Voltaire governance model works. Leios, if it delivers 65x throughput on schedule, changes Cardano’s competitive position for high-frequency use cases. That is not beating Ethereum in general-purpose smart contracts. It is owning a specific lane where Ethereum’s account model and complex staking actually are disadvantages.
Hoskinson’s frustration about attribution is understandable. His satisfaction should come from something else: the fact that Ethereum researchers are now exploring problems Cardano solved years ago is the clearest external validation that Cardano’s architectural bets were correct. Markets have not priced that in. ADA at $0.17 with Ethereum at $1,754 reflects where network effects sit today, not where architectural correctness points. Those two things can stay disconnected for a long time. But they rarely stay disconnected forever.
Five Years of Market Cap and Price: Ethereum vs Cardano
The market cap and price history of the two chains over five years tells a story that the architectural debate does not: Ethereum has held a scale advantage that compounded with every cycle, while Cardano peaked at the same moment in 2021 and has recovered less of that peak in the 2026 bear market. Both charts use end-of-year closing data from CoinLore and Kraken’s historical data, with current figures from CoinDesk and CoinGecko as of July 9, 2026.

What the price history shows
Both chains peaked in 2021 and corrected sharply in 2022. Ethereum recovered across 2023-2025 to set new highs. Cardano’s 2025 recovery to $1.31 was strong but still 58% below its 2021 ATH, and the 2026 correction has hit ADA harder in percentage terms (-94.6% from ATH vs ETH’s -64%). Architectural leadership and market recovery are two separate variables.

Frequently Asked Questions
Is the Ethereum UTXO proposal going to happen?
Wahrstätter’s proposal is a research post, not an EIP. No formal Ethereum Improvement Proposal has been filed. Any change of this scale would require community review, a formal EIP process and a hard fork. Ethereum’s roadmap is already crowded with Pectra, Fusaka and other upgrades. A UTXO payment layer would be a significant architectural addition and is not on any confirmed near-term schedule.
Did Ethereum copy Cardano’s staking model?
Ethereum’s Proof of Stake implementation and Cardano’s are both PoS but architecturally different. Cardano launched PoS in July 2020, Ethereum in September 2022. Cardano’s model allows staking without lockups. Ethereum’s requires bonding, has slashing risk and created the Lido liquid staking ecosystem as a workaround. Whether Ethereum consciously borrowed from Cardano or arrived at PoS independently with different design choices is contested.
Why does Cardano have better staking on paper but less usage?
Cardano’s native liquid staking is objectively simpler for users: no lockup, no slashing, no derivative token needed. Ethereum’s staking complexity created a multi-billion dollar ecosystem around Lido and similar platforms. Despite the simpler model, Cardano has fewer users, lower DeFi TVL and fewer applications because network effects in DeFi are sticky. Being better designed does not automatically attract users when the alternative has a multi-year head start and thousands of existing applications.
