Cardano founder Charles Hoskinson ignited a fresh debate on July 8, launching a big critique of the Ethereum community. His comments came as ADA price dropped 6.5% today, falling back below $0.17 after briefly trading above $0.18 during the recent market rally. The token is now near $0.167, giving up most of its weekly gains as the broader crypto market resets.
Hoskinson took to X to address what he described as an intentional silence around Cardano’s technology within Ethereum development circles.
“It’s not like I’ve been literally working on this topic for over 10 years of my life and launched a cryptocurrency that was number three on CoinMarketCap with millions of users to deploy it,” he wrote. “It’s literally a crime in the Ethereum inner circles to mention Cardano.”
The Cardano founder argued that the Extended UTXO (EUTXO) model represents the biggest innovation in the smart contract world. According to Hoskinson, Ethereum cannot mention this technology because they are “literally trying to copy it.”
The controversy stems from a larger technical discussion around how blockchains handle transaction data. One Ethereum developer commented on a thread about bringing native UTXO functionality to Ethereum. The developer argued that payments should be one-shot objects, not permanent state. The statement acknowledged that Bitcoin got this right and that Ethereum could bring the same idea to payments.

The post went further, claiming that proving existence from history while keeping only a spent bit in state could reduce permanent state by roughly 99.8%.
Ethereum uses an account-based model that tracks balances as persistent state. UTXO (Unspent Transaction Output) systems treat payments like individual coins that get spent and destroyed. Cardano’s EUTXO extends this concept to support smart contracts while preserving the UTXO model’s benefits.
Proponents argue that UTXO-based systems offer more predictable transaction costs, better parallelization, and enhanced privacy. Critics say they are harder to build complex applications on compared to Ethereum’s account model.
The debate has been ongoing for years, but Hoskinson’s comments suggest he views it as more than a technical disagreement. The friction between the two ecosystems is not new. Cardano has positioned itself as a research-driven alternative to Ethereum since its launch.
Hoskinson was a co-founder of Ethereum before leaving to start Cardano. His frustration appears to be rooted in what he sees as a refusal by Ethereum developers to acknowledge Cardano’s contributions. The fact that Ethereum developers are now exploring UTXO-related approaches, he argued, validates Cardano’s long-standing position.
The technical debate between account-based and UTXO-based models is not going away. Both approaches have their strengths. Ethereum’s account model has enabled the largest DeFi ecosystem in crypto. Cardano’s EUTXO model offers different trade-offs that may be better suited for certain applications.
What is clear is that the smart contract industry is still evolving. The fact that Ethereum developers are exploring UTXO-related optimizations suggests that the account model has limitations. Similarly, Cardano’s adoption has not matched Ethereum’s, showing that technical superiority alone does not guarantee market success.
For now, the debate continues.
Charles Hoskinson was an Ethereum co-founder before leaving to start Cardano. The two projects take different technical approaches, and there is a long history of rivalry and philosophical disagreement.
Could Cardano overtake EthereumIt’s possible but unlikely in the near term. Cardano’s EUTXO model offers technical advantages like predictable fees and parallel processing, but Ethereum has a massive head start in developer mindshare, DeFi liquidity, and institutional adoption.
Does Cardano have a futureYes, but it depends on execution. The Leios upgrade and growing RWA interest could drive adoption, and the community remains one of the most loyal in crypto. However, Cardano needs to translate its technical roadmap into real ecosystem growth and user activity to justify its long-term relevance.
