Vitalik: EIP-8141 is expected to be implemented within a year, fully addressing the account abstraction issue

Vitalik posted on the X platform stating that Ethereum has been discussing account abstraction (AA) since early 2016. Now, EIP-8141 serves as a comprehensive proposal aimed at addressing all remaining issues related to AA. The core concept of this proposal is "frame transactions," where a transaction contains N calls that can read each other's call data and can authorize the sender and gas payer.This mechanism supports various use cases: ordinary account transactions (such as multi-signature, variable keys, quantum-resistant signature schemes) are completed through validating frames and executing frames; when paying gas fees with non-ETH tokens, it can be achieved through the main contract without any intermediaries.In terms of privacy protocols, ZK-SNARK verification or the addition of two-dimensional randomness can be implemented through payment contracts. Regarding security, on-chain transactions are only valid when the validating frame returns an ACCEPT with a gas payment flag, while the memory pool layer will initially adopt conservative rules, gradually expanding later.EIP-8141 is highly complementary to FOCIL, with FOCIL ensuring quick transaction inclusion and AA ensuring that complex operations can be executed as first-class transactions directly. The proposal is also discussing EOA compatibility, which is theoretically feasible. After more than a decade of research, these technologies are expected to be implemented within a year through the Hegota fork.

Vitalik: FOCIL and EIP-8141 can work together to achieve censorship-resistant fast on-chain

Vitalik Buterin posted on the X platform, stating that there is an important synergy between the FOCIL mechanism and the account abstraction proposal Ethereum's EIP-8141 (based on 7701). EIP-8141 elevates smart accounts (including multi-signature, quantum-resistant signatures, key changes, Gas sponsorship, etc.) to "first-class citizens," meaning that operations from these accounts can be directly packaged as on-chain transactions without additional encapsulation.At the same time, privacy protocols can achieve a multi-tenant account model through the paymaster or 2D nonce mechanism, thereby gaining the same level of native support. FOCIL provides a censorship-resistant fast transaction inclusion mechanism. With the combination of both, various transactions, including smart wallet transactions, Gas sponsorship transactions, and privacy protocol transactions, can be included in blocks by one of the 17 roles (proposers or inclusions) randomly selected for each time slot.Vitalik stated that this design can ensure that transactions are almost guaranteed to be completed on-chain within 1-2 time slots in adversarial environments. In the current version, each FOCIL volume is approximately 8kB, which is relatively small, but there is a path for future expansion that could support most transactions in a block entering through the FOCIL channel. This architecture is similar in characteristics to the multi-parallel proposer (MCP) design, but differs in that FOCIL does not control the "last look" related to MEV, which is still allocated through the ePBS auction mechanism.Vitalik emphasized that even if 100% of block time slots are monopolized by adversarial parties through the proposer-builder separation (PBS) mechanism, refusing to connect to the public mempool or discriminating against specific applications, FOCIL can still ensure that all transactions receive fast inclusion. Although this design does not eliminate the centralization risk of the proposer role, it significantly weakens its power. Under the EIP-8141 framework, transactions from smart wallets or privacy protocols can be directly received by FOCIL inclusions through the public mempool without additional intermediaries or encapsulation processes.Vitalik concluded that Ethereum is accelerating the advancement of core architecture upgrades.

CCB responds to the transfer remark of Dogecoin being locked: detected high risk, the account will be set to "no receipt, no payment" status

Recently, Ms. Yu and her husband transferred 250 yuan in pocket money to each other through China Construction Bank, with the note "This week's Dogecoin," which led to an investigation by the bank and the locking of their accounts. The couple received calls from bank staff to verify their relationship and the reason for the transfer note, stating that the note triggered "virtual currency control," and their accounts would be set to a "no deposit, no withdrawal" status.The staff at the bank where Ms. Yu opened her account informed her that to unlock the account, she needed to submit her husband's bank statement for the past few months. After approval, she would then need to write a commitment letter, promising that the previous transactions were not related to virtual currency and that they would not participate in virtual currency transactions in the future. However, her husband strongly opposed the direct restriction on account usage and was negotiating with the staff at his bank. In response, China News Weekly called the China Construction Bank customer service for consultation, and the staff stated that they had not received any information regarding virtual currency control and suggested consulting the relevant branch for specific details.Subsequently, China News Weekly inquired at the branch of China Construction Bank in Tianjin where Ms. Yu opened her account, and the staff claimed they were unaware of the situation. Meanwhile, the staff at her husband's branch in Dalian stated that if the account involved virtual currency transactions, the bank would impose "no deposit, no withdrawal" control on the account. If the transfer note specified "Dogecoin," they would need to provide materials to prove that the note was unrelated to virtual currency. However, the issue lies in how to prove this; if only the bank statement is available, it cannot serve as valid proof. Therefore, such controlled accounts cannot be unlocked and can only be canceled.As for the specific regulations, the other party did not provide a clear response. Currently, Ms. Yu has submitted her husband's bank statement and a handwritten commitment letter and is applying to lift the account restrictions. Meanwhile, her husband's bank staff responded that after submitting their marriage certificate, they could apply to lift the restrictions. According to Xinhua News Agency, the China Internet Finance Association and six other associations jointly issued a risk warning, requiring all member units not to participate in virtual currency, real-world asset token issuance, and trading activities within the country, and reminding the public to discern risks and stay away from illegal activities.
