The "paymaster" feature allows paymaster contracts, which let you separate "who pays for the op" and "who sends the op".

“paymaster”功能允许使用 paymaster 合同，它可以让您区分“谁为操作付费”和“谁发送操作”。

All this ensures that if an op gets broadcasted through the mempool, then it is guaranteed that that op can get included on-chain and will pay fees - unless another op from that same account gets in first. Like Ethereum txs today.
All this prevents DoS attacks on the mempool.

所有这一切都确保了如果一个操作通过内存池广播，那么可以保证该操作可以被包含在链上并支付费用——除非来自同一账户的另一个操作首先进入。就像今天的以太坊 txs。
所有这些都可以防止对内存池的 DoS 攻击。

ERC-4337, and its predecessor EIP-2938, do this by enshrining a split between "validation" and "execution".
The validation step is bounded in how much gas it can consume, and cannot use "forbidden opcodes" that access state outside the account. If an op does this, it is rejected

ERC-4337 及其前身 EIP-2938 通过将“验证”和“执行”分开来做到这一点。
验证步骤受限于它可以消耗多少气体，并且不能使用访问帐户外部状态的“禁止操作码”。如果一个操作这样做，它将被拒绝

Doing this securely requires a mempool node to be able to determine whether or not a given op is guaranteed to pay fees before rebroadcasting it.
This is quite hard to do, because it requires checking that the op does not depend on state that might change in the next block.

安全地执行此操作需要内存池节点能够确定给定的操作是否保证在重新广播之前支付费用。
这很难做到，因为它需要检查操作是否不依赖于可能在下一个块中更改的状态。

This is the gold standard that the existing public mempool provides. And we absolutely need to provide the same guarantees for smart contract wallets, or else we risk worsening centralization and censorship.

这是现有公共内存池提供的黄金标准。我们绝对需要为智能合约钱包提供同样的保证，否则我们将面临加剧中心化和审查的风险。

You should be able to send an op into a public mempool, and if it pays enough fees, reliably expect it to get included. This should NOT depend on ANY:
* Centralized actors
* Reputation systems for op senders
* ETH held in a separate EOA
* External services for account creation

您应该能够将 op 发送到公共内存池中，并且如果它支付了足够的费用，则可以可靠地期望它被包含在内。这不应该取决于任何：
* 集中的演员
*操作发件人的信誉系统
* ETH 保存在单独的 EOA 中
* 用于创建帐户的外部服务

The big really valuable and necessary thing that ERC-4337 provides for account abstraction is a *decentralized fee market* for user operations going into smart contract wallets.

ERC-4337 为账户抽象提供的真正有价值和必要的东西是*分散的费用市场*，用于进入智能合约钱包的用户操作。

How long until there's a scandal related to water, and some writer calls it "Watergate" because that's the correct default modern English-language way to create a name for a scandal, without even realizing what they just did there?

多久才会出现与水有关的丑闻，一些作家称之为“水门事件”，因为这是为丑闻命名的正确默认现代英语方式，甚至没有意识到他们刚刚在那里做了什么？

@matthuang If crypto is a neighborhood does that make maximalists nimbys?

@BurnsPhone @jbaylina @gubsheep Gotta prove it without revealing x in the clear.

@BurnsPhone @jbaylina @gubsheep 必须在不明确透露 x 的情况下证明这一点。

@MazMHussain Reminds me of this invitation I got a couple years ago. "Come talk to anti-globalists from all over the world!"
(Needless to say, I did not respond) https://t.co/B9OEbhssVu

@MazMHussain 让我想起了几年前收到的邀请。 “来和来自世界各地的反全球化主义者交谈！”

@pourteaux @Noahpinion They talk the talk about "national sovereignty" but actually their entire economy depends on imports at every level. Even their memes are imported from 4chan.

@pourteaux @Noahpinion 他们谈论“国家主权”，但实际上他们的整个经济都依赖于各个层面的进口。甚至他们的表情包也是​​从 4chan 导入的。

@statelayer @BASEDghouls of course, should have known that there's a project for every noun these days... 😐

@statelayer @BASEDghouls 当然，应该知道这些天每个名词都有一个项目......😐

@delitzer @nascentxyz I definitely agree that some people are habitual traders who don't care about usage though.
But for that market, the question is how many of them are even on Uniswap now, versus on CEXes.
CEXes would be a uniswap chain's real competition.

@delitzer @nascentxyz 我绝对同意有些人是不关心使用的习惯性交易者。
但是对于那个市场，问题是现在有多少是在 Uniswap 上，而不是在 CEXes 上。
CEXes 将是 uniswap 链的真正竞争者。

@delitzer @nascentxyz Oh it's not about atomicity, it's about having an asset that you did not realize you would want to trade until 30 seconds ago, and being able to trade it quickly once you make that decision, and then being able to immediately use the asset that you traded into.

@delitzer @nascentxyz 哦，这不是关于原子性，而是关于拥有一个你直到 30 秒前才意识到你想要交易的资产，并且一旦你做出决定就能够快速交易它，然后能够立即使用您交易的资产。

@BurnsPhone @jbaylina @gubsheep Actually, this kind of bit arithmetic range proof is a key component in proving balances are non-negative in privacy solutions, including those used in Zcash, Monero and Ethereum-based systems. It may have helped you already.

@BurnsPhone @jbaylina @gubsheep 实际上，这种位算术范围证明是证明余额在隐私解决方案中是非负的关键组件，包括在 Zcash、Monero 和基于以太坊的系统中使用的余额。它可能已经帮助了你。
