@tlbtlbtlb f(k) = k, out-of-range.
@tlbtlbtlb f（k）=k，超出范围。

@polymutex Ideally no, but if a trusted setup is truly unavoidable that's fine.
@polymutex理想情况下不会，但如果可信的设置确实不可避免，那也没关系。
@rohitalmelkar Yes. It should be computationally infeasible to discover x where f(x) can't be computed, or (x, y) where x != y but f(x) = f(y).
(Or if the construction has *other* defects, eg. z where f_inv(z) can't be computed, those should also be hard to find)
@是的。在f（x）无法计算的地方，或者（x，y）在x！=但f（x）=f（y）。
（或者，如果建筑有*其他*缺陷，例如无法计算f_inv（z）的z，这些缺陷也应该很难找到）
@jasonhuan_ By definition, a function from [0...2^256-1] to [0...2^256 - 2] can't be truly invertible everywhere; there has to be some x where f(x) can't be computed, or some f(x) = f(y) collision. I want these unavoidable exceptions to be computationally infeasible to discover.
@根据定义，从[0…2^256-1]到[0…2^256-2]的函数不可能处处都是可逆的；必须存在一些不能计算f（x）的x，或者一些f（x）=f（y）碰撞。我希望这些不可避免的例外在计算上不可能被发现。
@domothy A really efficient solution could actually significantly simplify Verkle trees, erasure codes and many other constructions in ethereum, by making 32-byte chunks one-to-one mappable to F_p elements.
@domothy是一个非常有效的解决方案，通过将32字节块一对一映射到F_p元素，它实际上可以显著简化Verkle树、擦除代码和以太坊中的许多其他构造。
@zkproofs Either one. Basically I want a function where if you have black-box access to it on the stated domain/codomain you have no way to tell that it's not invertible.
@两个都有。基本上我想要一个函数，如果你在指定的域/密码域上有黑盒访问权，你就无法判断它是不可逆的。
Cryptography problem: make an invertible, easy-in-both-directions function from [0...2^256 - 1] to [0...2^256 - 2] (or more generally, -k for small k) where the exceptions to the invertibility are computationally infeasible to find.
Has there been any work on this?
密码学问题：在[0…2^256-1]到[0…2^256-2]（或者更一般地说，-k代表小k）的两个方向上制作一个可逆的、简单的函数，其中可逆性的异常在计算上是不可能找到的。
这方面有什么进展吗？
RT: Maybe states and localities can use some of their CARES money to put air filters in classrooms
COVID is bad but wait until you hear how air pollutions affects education attainment! https://twitter.com/vitalikbut...
RT：也许州和地方可以用他们的资金在教室里安装空气过滤器
新冠肺炎是不好的，但等你听到空气污染如何影响教育程度吧！https://twitter.com/vitalikbut...
@halabi @mattyglesias I think this is getting into "need expert advice to figure out how to reconcile the conflicting documents" territory. Which.... is itself a problem!
@halabi@mattyglesias我认为这正进入“需要专家建议，以找出如何协调冲突文件”的领域。哪一个这本身就是个问题！
@Noahpinion We also need to keep working hard on UV light, air filters and pan-coronavirus (incl mucosal) vaccines!
@我们还需要继续努力研发紫外线灯、空气过滤器和泛冠状病毒（包括粘膜）疫苗！
@halabi @mattyglesias Yeah I'm aware of all that. But according to the second link (residency requirement), I'm not eligible for nexus!
@哈拉比@mattyglesias是的，我知道这一切。但是根据第二个链接（居留要求），我没有资格申请nexus！
@halabi @mattyglesias Canadians are eligible only for Nexus, but that's only available to Canadians resident in Canada.

@john59eliot@TusharN27043081@mattyglesias@NickSzabo4很难说，twitter用户界面要求我打开一个私人浏览器标签才能看到他的推文，而我最近太懒了。我希望他能找到幸福。https://t.co/AD2SCbJoYt
@TusharN27043081 @mattyglesias Killed fewer people than some single days of covid.
@TusharN27043081@mattyglesias导致的死亡人数少于新冠病毒感染的几天。
@halabi @mattyglesias I think as the cool kids say, "check your privilege" 😋 https://t.co/BIH8ENqe9Z
@halabi@mattyglesias我想就像那些酷孩子说的，“检查你的特权”😋 https://t.co/BIH8ENqe9Z
@scott_lew_is @nicksdjohnson IMO we don't have any "standard templates" for any governance I would consider remotely acceptable.
(Coin voting is not acceptable regardless of how many delays and safeguards you bandaid around it)
@ SktTeLeWiSIS @尼克松JimsIO我们没有任何“标准模板”的任何治理，我认为是可以接受的。
（硬币投票是不可接受的，无论你有多少次拖延和保护措施）
@mattyglesias Can we ___-and-relax on all the other airport security measures (take off shoes + sweater, take out phone + wallet + laptop, also the on-plane safety videos) at some point? I would bet they save fewer lives per unit inconvenience than mask mandates do.
@mattyglesias我们能在某个时候放松一下所有其他机场安全措施（脱鞋+毛衣，拿出手机+钱包+笔记本电脑，还有机上安全视频）吗？我敢打赌，他们每单位拯救的生命比他们少。
