V神最新技能探讨 以太坊如何办理隐私裂痕?

This is of course rather stupid but it can be expanded. Think of a DDEX: here you can match someones trade by transferring tokens to a certain address. The only thing the user now needs to do is to broadcast that these tokens are deposited and either the maker of this order can now take them or the user includes a fee for someone else to ““mine”” this token on-chain which gives them incentive to pay for this gas. (This fee is hence in the calldata / salt). If the order is not matched the user can go on-chain to withdraw their tokens by simply providing the supplied calldata and showing that the user wants to cancel the order (to prevent the contract to try to match the order again). (Or the order is fulfilled already).

This seems like a doable first task. The second part about Whisper etc. etc. seems like there are a lot of rabbit holes to go down. If we get these simple mixers, one can start by having users actually generate multiple accounts and not immediately link them. Still relies on OPSEC of the user, but a good start for simple dApp usage.

Burrrata:

This is a situation that could use improvement. Two areas come to mind.

UX

要明晰的是,利用一个帐户的问题,可能在拥有的多个帐户之间举办生意业务,有效地使其成为单个“小我私家资料”,可以更轻松地以有意义的方法识别人员。

Jochem Brouwer:

Have people here thought about these issues more deeply?

譬喻,我可以查察获取ETH /令牌的地点,最终完成信息互换。互换有助于识别分叉式网络的垂纶潜在进攻前言,也展现了一些地理信息。这些事务产生的时间也有助于缩小区域配置。

You can even profile what kind of wallet scheme their using. Whether they have a cold storage address, are just using MetaMask or some other hot wallet, etc. This helps to know how difficult it would be to attack the user.

“这好像是一项可行的首要任务。关于Whisper等的第二部门好像有许多裂痕。”

burrrata:

另外,假如开拓人员或用户需要特另外尽力来建设隐私,没有这样经济鼓励,它最多只是一个开拓不利便的游戏理论业务决定。最好是选择隐私而不是就像我们本日看到的2FA和暗码打点器一样,它们是破例,而不是常态。

On the UX front, this is mainly a middleware and best practices issue. Can we help out wallets / web3 providers succeed at making this easier to set / generate accounts per dapp?

没错,可是开拓“通过付出Gas到达去中心化匿名”的Mixers需要layer2协议用于生意业务以外的工作(除非我们想要办理这个问题的方法是基于添加一些有限形式的譬喻图层抽象...)

This problem becomes exponentially worse when you add it to things like airdrops or giveaways where many people are associating their social media identity with their address. Anything that can be used to tie an address down to any other identifiable information makes this blockchain meta-information very powerful to attackers.
