ETH Vitalik Buterin praises Bitcoin's UTXO model
Ethereum co-founder Vitalik Buterin gave positive comments on Bitcoin's UTXO model. While sharing a study on Ethereum's expansion, Buterin pointed out that the Bitcoin community has led important innovative ideas, especially through solutions such as Utreexo. He believes that if Ethereum can learn from the advantages of the UTXO model, it will help improve the scalability and decentralization of the network. In particular, reducing the storage burden on verifiers and lowering the threshold for running nodes has become an important goal for Ethereum's long-term development. Buterin believes that such improvements will not only improve the network's transaction processing capabilities, but also maintain its decentralized structure.
Vitalik Buterin praised Bitcoin's UTXO model
Vitalik Buterin pointed out that the UTXO system adopted by Bitcoin is also worthy of Ethereum's reference in some respects. He particularly highlighted the Utreexo solution and said the Bitcoin community's efforts in this area are commendable. According to Buterin's assessment, the new capacity expansion method being developed by Ethereum may also draw on similar architectures. The core goal of this approach is to increase the transaction capacity of the Ethereum network without sacrificing decentralization.
In Ethereum, address balances and token records are continuously stored on the network. When users send ETH or hold ERC-20 tokens, these records are retained as part of the network's status. Over time, this will put greater storage pressure on the validator. Bitcoin's UTXO model tracks unspent transaction output. When a bitcoin is spent, the old UTXO becomes invalid and the transaction results generate a new UTXO record. In this way, the system can more efficiently manage the data structures tracked by the verifier.
Buterin emphasizes scalability and decentralization
In Buterin's evaluation, it not only focused on improving transaction capacity, but also emphasized protecting the decentralized structure of the Ethereum network. Allowing more users to run their own nodes is crucial to maintaining the network's ability to resist censorship. If Ethereum can draw on some of the advantages of the UTXO model, the network is expected to run more efficiently and the verification process will be simpler. However, how these changes integrate with Ethereum's existing account model and infrastructure remains an important issue for developers.
Assessment
Vitalik Buterin's positive comments on the Bitcoin UTXO model once again brought the differences in the technical architecture of the two blockchains to the forefront. In terms of Ethereum, scalability, node operation convenience and decentralized protection will continue to be important development themes for some time to come. Adapting some of the advantages of the UTXO model to the Ethereum infrastructure may help reduce the data and storage burden on verifiers. In addition, allowing more users to run their own nodes is of great significance to strengthening the decentralized structure and anti-censorship capabilities of the Ethereum network.
