为何以太坊下次升级中纳入 EIP-3074？账户抽象方案 ERC-4337 还不够吗？

After more than years of precipitation and improvement, the author's source was widely supported by the Ethereum community in the first meeting of Ethereum, and it was formally included in the next Ethereum hard fork, which was put forward by Ethereum researchers and developers. Its core is to make any externally owned account work like a smart contract wallet, and there is no need to deploy additional contracts and manually migrate. For example, it is said that the wallet user experience will be doubled, so how to do this? What is the difference between what is right and what is the difference between upgrading externally owned accounts? One type of account in Ethereum, such as direct control and management by users, is our commonly used mnemonic word wallet. For example, two new Ethereum virtual machine instructions are introduced, and an intelligent contract instruction is used to verify a signature and set a context variable based on the signature result. If the signature is valid and the signer's address matches the given authorized address, the instruction allows an intelligent contract generation. Table 1. A delegated instruction that performs an operation to realize authorization control is similar to the existing instruction for executing an external call. The difference is that the authorized address previously set by the instruction will be used as the caller's address, which means that the authorized sender will be used instead of the contract itself. The whole process is that the user signs the authorization message contract to receive and verify the contract use and the instruction to send the transaction on behalf of the user without directly using the user's private key and then returning to the node. The difference between the result and the user is that there is no need to change the agreement level. The main goal of the consensus layer is to realize the account abstraction, allow the smart contract to directly own funds and have functions similar to those of the Ethereum account, that is, let the smart contract account have the characteristics of actively initiating transactions and need to be implemented through the Ethereum hard fork. The main goal is to entrust the control similar to the smart contract to the smart contract, so that the smart contract can conduct transactions on behalf of the user and support bulk transactions. The three parties pay the gas bill to execute the transaction and other functions. Although it makes the account have the function of smart contract wallet, the account is still completely lost if the key is stolen, unless a special contract is set up for account recovery. Why is it important to support each chain in the multi-chain era? It takes a lot of development work, while the proposed migration transaction requires the user to manually send a migration transaction to the smart contract. Compared with other proposals, it is simple and efficient to use it directly on all chains and does not require users to manually migrate, so that users can enjoy the function of smart contracts without additional processes. After improvement and testing, the technical security issues that the Ethereum community will be worried about will be widely supported by the community, which will have an impact on many fields in the Ethereum ecosystem, such as the bulk transaction function in the field, which will greatly improve liquidity providers and The efficiency of traders reduces the cost of participation. In addition, by authorizing the user's account to execute the transaction, the application can pay for the user as a sponsor, thus lowering the threshold for the user to use the product. In the field of full-chain games, the user can authorize the third party to operate the account, thus avoiding the problem that each transaction requires the user to confirm and pay the fee on the chain. Game developers or other third parties can execute the transaction instead of the user. Only one-time authorization is needed to simplify the transaction process and improve the fluency of the game. Potential risks In the Ethereum transaction, the node verifier needs to know the details of the transaction accurately in order to handle them correctly, so as to ensure the security and stability of the network. In the process, allowing the intelligent contract representative to execute the transaction, interacting with other contracts or accounts may change the account status before and after the transaction execution, and it is difficult for the witness to accurately predict the impact of the transaction. In addition, although the user can authorize the third party to operate the account by signing, it also means that the third party can operate the user's account to a certain extent, which may lead to potential security problems. If the authority of the third party is abused or hacked, the user's funds and personal information may be threatened. 比特币今日价格行情网_okx交易所app_永续合约_比特币怎么买卖交易_虚拟币交易所平台
