In this context, Buterin, drawing attention to the UXTO model used by Bitcoin, stated, “The Bitcoin camp deserves great praise for pioneering a significant portion of these kinds of ideas through Utreexo and others.”
Looking at current models, in Ethereum, ETH or ERC-20 token transactions increase the storage load on nodes by creating records in the network’s persistent state. In contrast, in Bitcoin’s UTXO model, spent records are removed from the system and new UTXOs are created. Thus, since there is no need to maintain old records, the storage load on validators is reduced.
However, Buterin added that his statement does not mean Ethereum will completely switch to the UTXO model. He stated that this approach is currently being evaluated as part of research and protocol design, and that it would be incorrect to interpret this statement as Ethereum abandoning its current account model anytime soon.
However, according to experts, if Ethereum’s efforts in this direction come to fruition, the goal is to achieve higher transaction capacity while keeping node operating costs under control and preserving its decentralized features.
