Cardano founder Charles Hoskinson criticizes Ethereum UTXO proposal as controversy intensifies

Charles Hoskinson criticizes Ethereum\'s UTXO proposal, technical route battle resumes

Charles Hoskinson criticized a proposal by Ethereum developers to adopt elements of the UTXO transaction model, which aims to address the network\'s growing database size. The Cardano founder\'s comments stem from a plan released by Ethereum researchers similar to the one Cardano has relied on since its launch.

Ethereum researcher Tony Walstadt proposed the plan through Ethereum improvement proposal EIP-8141 (also known as \"frame transactions\"). The proposal aims to reduce the amount of active data stored by Ethereum by changing the way simple transfers are processed. Rather than permanently retaining complete account information for one-time transfers, the plan allows these transactions to rely on historical blockchain records. In this way, the network retains only one spent mark in active storage, reducing long-term database growth.

According to Valstadt, the design can reduce unnecessary storage growth for simple transfers at the base level by 99.8%. Currently, the proposal has entered the \"straw man\" discussion stage of Ethereum, and co-founder Vitalik Buterin is monitoring its progress.

Hoskinson responded on social media that Ethereum was exploring ideas that Cardano had adopted many years ago. He also claimed that there was a tacit understanding within the Ethereum community that was unwilling to recognize Cardano\'s technical contributions.

Ethereum explores hybrid design to meet storage challenges

Ethereum has always adopted an account-based model that stores the balance and status of each active wallet. While this design is effective in supporting smart contracts, as activity increases, the storage requirements of the network also rise. Cardano, on the other hand, builds its blockchain based on an extended unspent transaction output (eUTXO) model. The framework extends Bitcoin\'s original UTXO architecture while implementing advanced smart contract functionality.

Hoskinson pointed out that Cardano chose the eUTXO model from the beginning to improve scalability and storage efficiency. As a result, Ethereum\'s latest proposal rekindled comparisons between these two competing blockchain designs. Rather than proposing a complete shift to the UTXO model, Ethereum developers are considering a hybrid solution-using UTXO-style mechanisms only for simple transfers, while retaining the existing account system for decentralized applications.

This distinction is crucial because Ethereum supports thousands of decentralized financial protocols that rely on its current architecture. Therefore, developers must ensure that any changes do not break existing apps or cause compatibility issues. The proposal has also revived attention to Hoskinson\'s past with Ethereum. He left the project in 2014 due to differences with Vitalik Butrin over the long-term commercial direction of Ethereum.

Proposal may affect Ethereum\'s future expansion strategy

Discussions around EIP-8141 highlight Ethereum\'s efforts to manage long-term network growth without abandoning existing infrastructure. Although the proposal is still in the early stages of discussion, it has sparked a broader debate about blockchain architecture and scalability. Hoskinson\'s response added a new dimension to the debate-he believed the proposal validated design concepts that Cardano had implemented many years ago. Whether Ethereum ultimately adopts a hybrid solution or finds another alternative, the proposal rekindled comparisons of the technological foundations of the two leading smart contract networks.

Ethereum\'s storage proposal reopens a long-standing discussion about blockchain scalability and network design. While the researchers evaluated the hybrid approach, Hoskinson insisted that the proposal reflected the concept that Cardano had incorporated from the beginning, keeping the competition between the two blockchain ecosystems a constant focus.
